Whitewall

Whitewall (pronounced hwahyt-wawl or wahyt-wawl)

(1) A tyre (or tire), almost always pneumatic, with a sidewall with a white circular line of varying widths.

(2) Having white sidewalls (of a tyre).

(3) In US military use, a hair cut with a closely cropped back and sides and the hair on the top of the head left longer.

(4) In UK dialect (Northamptonshire), the spotted flycatcher (the bird so-called because of the white color of the under parts).

1950–1955: The construct was white + (side)wall.  White pre-dates 900 and was from the Middle English whit & hwit, from the Old English hwīt (whiteness, white food, white of an egg (and in late Old English “a highly luminous color devoid of chroma”)), from the Proto-West Germanic hwīt, from the Proto-Germanic hwītaz, from the primitive Indo-European weydós, a by-form of weytós (bright; shine). It was cognate with the German weiss, the Old Norse hvītr and the Gothic hweits; akin to wheat.  The idea of the “whites of the eye” was known in the late fourteenth century while the use of the term “white man” emerged in the late 1600s.  Wall pre-dates 900 and was from the Middle English wal, from the Old English weall (wall, dike, earthwork, rampart, dam, rocky shore, cliff), from the Proto-West Germanic wall (wall, rampart, entrenchment), from the Latin vallum (wall, rampart, entrenchment, palisade), from vallus (stake, post), from the primitive Indo-European welH- (to turn, wind, roll).  It was likely conflated with waw (a wall within a house or dwelling, a room partition), from the Middle English wawe, from the Old English wāg & wāh (an interior wall, divider).  It was cognate with the North Frisian wal (wall), the Saterland Frisian Waal (wall, rampart, mound), the Dutch wal (wall, rampart, embankment), the German Wall (rampart, mound, embankment) and the Swedish vall (mound, wall, bank”).  The forms white wall & white-wall are also used.  Whitewall is a noun & adjective; the noun plural is whitewalls.

Wide whitewalls on 1953 Packard Caribbean Convertible (left), narrow whitewalls on 1967 Mercedes-Benz 600 (centre) and triple whitewalls on 1966 Cadillac Coupe De Ville (right) (there were also double whitewalls).

Whitewall tyres became available in the early years of the twentieth century but it wasn’t until the 1930s they became a noted feature on luxury cars sold in the US and, in the way these things work, they were soon also an option on lower-priced models although, being relatively expensive and offering no functionality, the take-up rate was low.  The very existence of the whitewall was, stylistically, something of a throwback because the earliest pneumatic tyres were an off-white, the color of the natural rubber formula and the manufacturers soon added a zinc oxide to the mix for no reason other than producing a bright white which was more appealing in showrooms.  Given the unsealed roads of the era, the stark white didn’t long last in use and tyres quickly degenerated to a “dirty beige” and although “tyre cleaning” products were available, it was a sisyphean task and presumably few persisted.  In 1910 the BF Goodrich Company began adding carbon black to its various formulae after tests confirmed this added strength and durability to the rubber.  Rapidly the technique was adopted by the industry although because carbon black was an additional input cost, some tyres were produced with the additive used only for the portion of the rubber used for the tread surface, meaning the sidewalls remained white.  The first whitewalls were thus a product of cost-cutting and it’s an irony the look would more than a decade later be picked up as a marker of wealth and luxury although the commercial “whitewalls” would be a strip of white rubber added during the manufacturing process to an all-black carcass.  As a “discovery” the whitewall can be thought serendipitous.

The whitewall became more popular in the late 1940s until the Korean War (1950-1953) caused a squeeze on rubber supplies but once the peacetime returned, so did the whitewall and the width grew, often measuring 2½-3 inches (65-75 mm), something made possible by the physical size of tyre sidewalls increasing during the 1950s.  The perception now is the fashion was very much a US taste and while there’s some truth in that, American culture in the 1950s exerted a great influence and whitewalls were seen in Europe, Australia and Japan and for some reason the Italian fashion magazines seemed particularly taken with them for their photo-shoots.  Curiously, the US industry seemed to lose interest in whitewalls between 1961-1963, just as the wild fins of the era suddenly vanished although there was a period of transition, the “standard” whitewall shrinking to a width of 1 inch (25 mm) and sometimes less.  During the 1960s, although whitewalls remained a fixture on the more up-market mainstream vehicles the preferred look for high-performance machinery (it was the “muscle-car” era) was the “raised letter” tyre which spelled out the manufacturer’s name and often model of tyre, the free advertising greatly pleasing.  At the same time, the muscle car circle developed a taste for “red-line” tyres” which featured a thin red strip.

The Ferrari was a gift from Enzo Ferrari (1898-1988) to Henry Ford II (1917–1987) and was the last non-racing Ferrari bodied by coachbuilder Carrozzeria Touring Superleggera.  The whitewall tyres were fitted especially for US delivery and Ford used the car during its evaluation process for the 1955 Thunderbird which picked up styling cues including the hood (bonnet) scoop and egg crate grille.  The Mercedes-Benz 450 SL illustrates just how jarring whitewalls can be if used on vehicles not suited to their presence.  On the early R107s (1971-1989) and C107s (the SLC, 1971 1981), thin whitewalls were sometime fitted to US market cars and even then there was comment about they really didn’t suit.  On the 450 SL pictured, the error is compounded by the fitting of the “chrome” wheel arch trims.  This was an unfortunate trend (which spread also to Jaguar, BMW and beyond) which began with their appearance in 1963 on the Mercedes-Benz 600 (W100, 1963-1981) but on the original they were of metal whereas the aftermarket ones were almost always anodized plastic.

Lettrism

Lettrism (pronounced let-riz-uhm)

A French avant-garde art and literary movement established in 1946 and inspired, inter alia, by Dada and surrealism.  The coordinate term is situationism.

1946: From French lettrisme, a variant of lettre (letter).  Letter dates from the late twelfth century and was from the From Middle English letter & lettre, from the Old French letre, from the Latin littera (letter of the alphabet (in plural); epistle; literary work), from the Etruscan, from the Ancient Greek διφθέρ (diphthérā) (tablet) (and related to diphtheria).  The form displaced the Old English bōcstæf (literally “book staff” in the sense of “the alphabet’s symbols) and ǣrendġewrit (literally “message writing” in the sense of “a written communication longer than a “note” (ie, something like the modern understanding of “a letter”)).  The –ism suffix was from the Ancient Greek ισμός (ismós) & -isma noun suffixes, often directly, sometimes through the Latin –ismus & isma (from where English picked up ize) and sometimes through the French –isme or the German –ismus, all ultimately from the Ancient Greek (where it tended more specifically to express a finished act or thing done).  It appeared in loanwords from Greek, where it was used to form abstract nouns of action, state, condition or doctrine from verbs and on this model, was used as a productive suffix in the formation of nouns denoting action or practice, state or condition, principles, doctrines, a usage or characteristic, devotion or adherence (criticism; barbarism; Darwinism; despotism; plagiarism; realism; witticism etc).  Letterism is listed by some sources as an alternative spelling but in literary theory it used in a different sense.  Lettrism and lettrist are nouns; the noun plural is letterists.

Letter from letterist Lindsay Lohan (2003).

A Lettrist was (1) one who practiced Lettrism or (2) a supporter or advocate of Lettrism.  Confusingly, in the English-speaking world, the spelling Letterist has been used in this context, presumably because it’s a homophone (if pronounced in the “correct (U)” way) and the word is “available” because although one who keeps as diary is a “diarist”, even the most prolific of inveterate letter writers are not called “letterists”.  The preferred term for a letter-writer is correspondent, especially for those who writes letters regularly or in an official capacity.  The Letterist International (LI) was a Paris-based collective of radical artists and cultural theorists which existed 1952-1957 before forming the Situationist International (SI), a trans-European, unstructured collective of artists and political thinkers which eventually became more a concept than a movement.  Influenced by the criticism that philosophy had tended increasingly to fail at the moment of its actualization, the SI, although it assumed the inevitability of social revolution, always maintained many (cross-cutting) strands of expectations of the form(s) this might take.  Indeed, just as a world-revolution did not follow the Russian revolutions of 1917, the events of May, 1968 failed to realize the predicted implications; the SI can be said then to have died.  The SI’s discursive output between 1968 and 1972 may be treated either as a lifeless aftermath to an anti-climax or a bunch of bitter intellectuals serving as mourners at their own protracted funeral.  In literary theory, while “Lettrism” has a defined historical meaning, the use of “letterism” is vague and not a recognized term although it has informally been used (often with some degree of irony) of practices emphasizing the use of letters or alphabetic symbols in art or literature and given the prevalence of text of a symbolic analogue in art since the early twentieth century, it seem surprising “letterism” isn’t more used in criticism.  That is of course an Anglo-centric view of things because the French Lettrists themselves are said to prefer the spelling “Letterism”.

The French literary movement Lettrism was founded in Paris in 1946 and the two most influential figures in the early years were the Romanian-born French poet, film maker and political theorist Isidore Isou (1925–2007) and his long-term henchman, the French poet, & writer Maurice Lemaître (1926-2018).  Western Europe was awash with avant-garde movements in the early post-war years but what distinguished Lettrism was its focus on breaking down (deconstruction was not yet a term used in this sense) traditional language and meaning by emphasizing the materiality of letters and sounds rather than conventionally-assembled words.  Scholars of linguistics and the typographic community had of course long made a study of letters, their form, variation and origin, but in Lettrism it was less about the letters as objects than the act of dismantling the structures of language letters created, the goal being the identification (debatably the creation) of new forms of meaning through pure sound, visual abstraction and the aesthetic form of letters.  Although influenced most by Dada and surrealism, the effect the techniques of political propaganda used during the 1930s & 1940s was noted by the Lettrists and their core tenent was an understanding of the letter itself as the fundamental building block of art and literature.  Often they would break down language into letters or phonetic sounds, assessing and deploying them for their aesthetic or auditory qualities rather than their conventional meaning(s).  In that sense the Lettrists can be seen as something as precursor of post-modernism’s later “everything is text” orthodoxy although that too has an interesting origin.  The French philosopher Jacques Derrida (1930-2004) made famous the phrase “Il n'y a pas de hors-texte” which often is translated as something like “there is no meaning beyond the text” but “hors-texte” (outside the text) was printers’ jargon for those parts of a book without regular page numbers (blank pages, copyright page, table of contents et al) and Derrida’s point actually was the hors-texte must be regardes as a part of the text.  There was much intellectual opportunism in post modernism and for their own purposes it suited may to assert what Derrida said was “There is nothing outside the text” and what he meant was “everything is part of a (fictional) text and nothing is real” whereas his point was it’s not possible to create a rule rigidly which delineates what is “the text” and what is “an appendage to the text”.  Troublingly for some post modernists, Derrida did proceed on a case-by-case basis although he seems not to have explained how the meaning of the text in an edition of a book with an appended "This page is intentionally left blank" page might differ from one with no such page.  It may be some earnest student of post-modernism has written an essay convincingly exactly that.

The Lettrism project was very much a rejection of traditional language structures and the meanings they denoted; it was a didactic endeavor, the Lettrists claiming not only had they transcended conventional grammar & syntax but they could obviate even a need for meaning in words, their work a deliberate challenge to their audiences to rethink how language functions.  As might be imagined, their output was “experimental” and in addition to some takes on the ancient form of “pattern poetry” included what they styled “concrete poetry” & “phonetic poetry”, visual art and performance pieces which relied on abstraction, the most enduring of which was the “hypergraphic”, an object sometimes describe as “picture writing” which combined letters, symbols, and images, blending visual and textual elements into a single art form, often as collages or as graphic-like presentations on canvas or paper.  This wasn’t a wholly new concept but the lettrists vested it with new layers of meaning which, at least briefly, intrigued many although it was dismissed also as “visual gimmickry” or that worst of insults in the avant-garde: “derivative”.  Despite being one of the many footnotes in the history of modern art, Lettrism never went away and in a range of artistic fields, even today there are those who style themselves “lettrists” and the visual clues of the movement’s influence are all around us.

Chrysler’s letterism: The Chrysler 300 “letter series” 1955-1965.

The “letter series” Chrysler 300s were produced in limited numbers in the US between 1955-1965; technically, they were the high-performance version of the luxury Chrysler New Yorker and the first in 1955 was labeled C-300, an allusion to the 300 hp (220 kW) 331 cubic inch (5.4 litre) Hemi V8, then the most powerful engine offered in a production car.  The C-300 was well received and when an updated version was released in 1956, it was dubbed 300B, the annual releases appending the next letter in the alphabet as a suffix although in 1963 “I” was skipped when the 300H was replaced by the 300J, the rationale being it might be confused with a “1” (ie the numeral “one”), the same reasoning explaining why there are so few “I cup” bras, some manufacturers filling the gap in the market between “H cup” & “J cup” with a “HH cup” but there’s no evidence the corporation’s concerns ever prompted them to ponder a “300HH”.  Retrospectively thus, the 1955 C-300 is often described as the 300A although this was never an official factory designation.  While in the narrow technical sense not a part of the “muscle car” lineage (defined by the notion of putting a “big” car’s “big” engine into a smaller, lighter model), the letter series cars were an important part of the “power race” of the 1950s and an evolutionary step in what would emerge in 1964 as the muscle car branch and the most plausible LCA (last common ancestor) of both was the Buick Century (1936-1942).  The letter series was retired after 1965 because the market preference for high-performance car had shifted to the smaller, lighter, pony cars & intermediates (neither of which existed in the early years of the 300) though the “non letter series” 300s (introduced in 1962) continued until 1971 with an toned-down emphasis on speed and a shift to style.

1955 Chrysler C-300 (300A).

The 1955 C-300 typified Detroit’s “mix & match” approach to the parts bin in that it conjured something “new” at relatively low cost, combining the corporation’s most powerful Hemi V8 with the New Yorker Series (C-68) platform, the visual differentiation achieved by using the front bodywork (the “front clip” in industry jargon) from the top-of-the-range Imperial.  The justification for the existence of the thing was to fulfill the homologation requirements of NASCAR (National Association for Stock Car Auto Racing) that a certain number of various components be sold to the public before a car could be defined as a “production” car (ie a “stock” car, a term which shamelessly would be prostituted in the years to come) and used in sanctioned competition.  Accordingly, the C-300 was configured with the 331 cubic inch Hemi V8 fitted, with dual four barrel carburetors, solid valve lifters and a high-lift camshaft profiled for greater top-end power.  Better to handle the increased power, stiffer front and rear suspension was used and it was very much in the tradition of the big, powerful grand-touring cars of the 1930s such as the Duesenberg SJ, something that with little modification could be competitive on the track.  Very successful in NASCAR racing, the C-300 also set a number of speed records in timed trials but it was very much a niche product; despite the price not being excessive for what one got, only 1,725 were made.

The 300B used a updated version of the C-300s body so visually the two were similar although, ominously, the tailfins did grow a little.  The big news however lay under the hood (bonnet) with the Hemi V8 enlarged to 354 cubic inches (5.8 litres) and available either with 340 horsepower (254 kW) or in a high- compression version generating 355 (365), the first time a US-built automobile was advertised as producing greater than one horsepower per cubic inch of displacement.  It was a sign of the times; other manufacturers took note.  The added power meant a top speed of around 140 mph (225 km/h) could be attained, something now to ponder given the retardative qualities of the braking system but also of note was the season's much talked-about option: the "Highway Hi-Fi" phonograph player which allowed vinyl LP records to be played when the car was on the move; the sound quality was remarkably good but on less than smooth surfaces, experiences were mixed.  Success on the track continued, the 300B wining the Daytona Flying Mile with a new record of 139.373 MPH, and it again dominated NASCAR, repeating the C-300’s Grand National Championship.  Despite that illustrious record, only 1,102 were sold.

1957 Chrysler 300C.

The 1955-1956 Chryslers had a balance and elegance of line which could have remained a template for the industry but there were other possibilities and these Detroit choose to pursue, creating a memorable era of extravagance but one which proved a stylistic cul-de-sac.  The 1957 300C undeniably was dramatic and featured many of the motifs so associated with the US automobile of the late 1950s including the now (mostly) lawful quad-headlights, the panoramic “Vista-Dome” windshield, the lashings of chrome and, of course, those tailfins.  The Hemi V8 was again enlarged, now in a “tall deck” version out to 395 cubic inches (6.4 litres) rated at 375 horsepower (280 kW) and for the first time a convertible version of the 300 was available.  By now the power race was being run in earnest with General Motors (GM) offering fuel-injected engines and Mercury solving the problem in the traditional American (there’s no replacement for displacement) way by releasing a 430 cubic inch (7.0 litre) V8 although it was so big and heavy it made the bulky Hemi seem something of a lightweight; the 430 did however briefly find a niche in in power-boat racing.  For 300C owners who wanted more there was also a high-compression version with more radical valve timing rated at 390 horse power (290 kW) and this was for the first time able to be ordered with a three-speed manual transmission.  Few apparently felt the need for more and of the 2,402 300Cs sold (1,918 coupes & 484 convertibles), only 18 were ordered in high-compression form.

1958 Chrysler 300D.

Again using the Hemi 392, now tuned for a standard 380 horsepower (280 kW), there was for the first time the novelty of the optional Bendix “Electrojector” fuel injection, which raised output to a nominal 390 horsepower (290 kW) although its real benefit was the consistency of fuel delivery, overcoming the starvation encountered sometimes under extreme lateral load.  Unfortunately, the analogue electronics of the era proved unequal to the task and the unreliability was both chronic and insoluble, thus almost all the 21 fuel-injected cars were retro-fitted with the stock dual-quad induction system and it’s believed only one 300D retains its original Bendix plumbing.  Also rare was the take-up rate for the manual transmission option and interestingly, both the two known 300Ds so equipped were ordered originally with carburetors rather than fuel injection.  The engineers also secured one victory over the stylists.  After testing on the proving grounds determined the distinctive, forward jutting “eyebrow” header atop the windscreen reduced top speed by 5 mph (8 km/h), they managed to convince management to authorize an expensive change to the tooling, standardizing the convertible’s compound-curved type “bubble windshield”, a then rare triumph of function over fashion.  Although the emphasis of the letter series cars was shifting from the track to the roads, the things genuinely still were fast and one (slightly modified) 300D was set a new class record of 156.387 mph (251.681 km/h) on the Bonneville Salt Flats.  Production declined to 810 units (619 coupes & 191 convertibles).

1959 Chrysler 300E.

With the coming of the 1959 range, the Hemi was retired and replaced by a new 413 cubic inch (6.8 litre) V8 with wedge-shaped combustion chambers.  Lighter by some 100 lb (45 kg) and cheaper to produce than the Hemi with its demanding machining requirements and intricate valve train, the additional displacement allowed power output to be maintained at 380 horsepower (280 kW) while torque (something more significant for what most drivers on the street do most of the time actually increased).  The manual transmission option was also deleted with no market resistance and despite the lower production costs, the price tag rose, something probably more of a factor in the declining sales than the loss of the much vaunted Hemi and, like the 300D (and most of the rest of the industry) the year before, the economy was suffering in the relatively brief but sharp recession and Chrysler probably did well to shift 390 units (550 coupes & 140 convertibles).

1960 Chrysler 300F (left) and 300F engine with Sonoramic intake in red (right).

Although the rococo styling cues remained, underneath now lay radical modernity, the corporation’s entire range (except for exclusive Imperial line) switching from ladder frame to unitary construction.  The stylists however indulged themselves with more external flourishes, allowing the tailfins an outward canter, culminating sharply in a point and housing boomerang-shaped taillights.  Even the critics of such things found it a pleasing look although they were less impressed by the faux spare tire cover (complete with an emulated wheel cover!) on the trunk (boot), dubbing it the “toilet seat”.  The interior though was memorable with four individual bucket in leather with a center console between extending the cockpit’s entire length and there was also Chrysler’s intriguing electroluminescent instrument display which, rather than being lit with bulbs, exploited a phenomenon in which a material emits light in response to an electric field; the ethereal glow was much admired.  Buyers in 1959 may have felt regret in not seeing a Hemi in the engine bay, but after lifting the hood (bonnet) of a 300F they wouldn’t have been disappointed because, in designer colors (gold, silver, blue & red) sat the charismatic “Sonoramic” intake manifold, a “cross-ram” system which placed the carburetors at the sides of engine, connected by long tubular runners.  What the physics of this did was provide a short duration “supercharging” effect, tuned for the mid-range torque most used when overtaking at freeway speeds.  Also built were a handful of “short ram” Sonoramics which had the tubes (actually with the same length) re-tuned to deliver top-end power rather than mid-range torque.  Rated at a nominal 400 (300 kW) horsepower, these could be fitted also with the French-built Pont-a-Mousson 4-speed manual transmission used in the Chrysler V8-powered Facel Vega and existed only for the purpose of setting records, six 300Fs so equipped showing up at the 1960 Dayton Speed Week where they took the top six places in the event’s signature Flying Mile, crossing the traps at between 141.5-144.9 mph (227.7-233.3 km/h).  The market responded and sales rose to 1217 (969 & 248 convertibles) and the 300F (especially those with the “short ram” Sonoramics) is the most collectable of the letter series.

1961 Chrysler 300G.

The 300G gained canted headlights, another of those styling fads of the 1950s & 1960s which quickly became passé but now seem a charming period piece.  There was the usual myriad of detail changes the industry in those days dreamed up each season, usually for no better reason that to be “different” from last year’s model and thus be able to offer something “new”.  As well as the slanted headlights, the fins became sharper still and taillights were moved.  Mechanically, the specification substantially was unaltered, the Sonoramic plumbing carried over although the expensive, imported Pont-a-Mousson transmission was removed from the option list, replaced by Chrysler’s own heavy-duty 3-speed manual unit, the demand for which was predictably low.  The lack of a fourth cog didn’t impede the 300G’s performance in that year’s Daytona Flying Mile where one would again take the title with a mark of 143 mph (230.1 km/h) and to prove the point a stock standard model won the one mile acceleration title.  People must have liked the headlights because production reached 1617 units (1,280 coupes & 337 convertibles).

1962 Chrysler 300H.

Perhaps a season or two too late, Chrysler “de-finned” its whole range, prompting their designer (Virgil Exner (1909–1973)) to lament his creations now resembled “plucked chickens”.  For 1962 the 300 name also lost some of its exclusivity with the addition to the range of the 300 Sport series (offered also with four-door bodywork) and to muddy the waters further, much of what was fitted to the 300H could be ordered as an option on the basic 300 so externally, but for the distinctive badge, there was visually little to separate the two.  Mechanically, the “de-contenting” which the accountants had begun to impose as the industry chase higher profits (short-term strategies to increase “shareholder value” are nothing new) was felt as the Sonoramic induction system moved to the 300H’s option list with the inline dual 4-barrel carburetor setup last seen on the 300E now standard.  However, because of weight savings gained by the adoption of a shorter wheelbase platform, the specific performance numbers of 300H actually slightly shaded its predecessor but the cannibalizing of the 300 name and the public perception the thing’s place in the hierarchy was no longer so exalted saw sales decline 570 (435 coupes & 135 convertibles), the worst year to date.  The magic of the 300 name however seemed to work because Chrysler in the four available body styles (2 door convertible, 2 & 4 door hardtop & 4 door sedan) sold 25,578 of the 300 Sport series, exceeding expectations.  Since 1962, the verbal shorthand to distinguished between the ranges has been “letter series” and “non letter series” cars.

1963 Chrysler 300J.

Presumably in an attempt to atone for past sins, a spirit of rectilinearism washed through Chrysler’s design office while the 1963 range was being prepared and it would persist until the decade’s end when new sins would be committed.  Unrelated to that was the decision to skip a 300I because of concerns it might be read as the wholly numeric 3001.  The de-contenting (now an industry trend) continued with the swivel feature for the front bucket seats deleted while full-length centre console was truncated at the front compartment with the rear seat now a less eye-catching bench.  The 413 V8 was offered in a single configuration but the Sonoramics were again standard and the manual transmission remained optional, seven buyers actually ticking the box. The 300J was still a fast car, capable of a verified 142 mph (229 km/h) although the weight and gearing conspired against acceleration but a standing quarter mile (400 m) ET (elapsed time) of 15.8 was among the quickest of the cars in its class.  Still, it did seem the end of the series might be nigh with the convertible no longer offered and the sales performance reflected the feeling, only 400 coupes leaving the showrooms.

The BUFF: The new version of the Boeing B-52 Stratofortress (replacing the B-52H) will be the B-52J, not B-52I or B-52HH.   

The US Air Force also opted to skip “I” when allocating a designation for the updated version of the Boeing B-52 Stratofortress (1952-1962 and still in service).  Between the first test flight of the B-52A in 1954 and the B-52H entering service in 1962, the designations B-52B, B-52C, B-52D, B-52E, B-52F & B-52G sequentially had been used but after flirting with whether to use B52J as an interim designation (reflecting the installation of enhanced electronic warfare systems) before finalizing the series as the B-52K after new engines were fitted, in 2024 the USAF announced the new line would be the B-52J and only a temporary internal code would distinguish those not yet re-powered.  Again, the “I” was not used so nobody would think there was a B521.  Although the avionics, digital displays and ability to carry Hypersonic Attack Cruise Missile (HACM, a scramjet-powered weapon capable exceeding Mach 5) are the most significant changes for the B-52J, visually, it will be the replacement of the old Pratt & Whitney TF33 engines with new Rolls-Royce F130 units which will be most obvious, the F130 promising improvements in fuel efficiency of some 30% as well as reduction in noise and exhaust emissions.  Already in service for 70 years, apparently no retirement date for the B-52 has yet been pencilled-in.  In USAF (US Air Force) slang, the B-52 is the BUFF (the acronym for big ugly fat fellow or big ugly fat fucker depending on who is asking).  From BUFF was derived the companion acronym for the LTV A-7 Corsair II (1965-1984, the last in active service retired in 2014) which was SLUFF (Short Little Ugly Fat Fellow or Short Little Ugly Fat Fucker).

1964 Chrysler 300K.

Selling in 1963 only 400 examples of what was intended as one of the corporations “halo” cars triggered management to engage in what the Americans had come to call an “agonizing reappraisal”.  The conclusion drawn was the easiest way to stimulate demand was to lower the basic entry price to ownership of the name and if buyers really wanted the fancy stuff once fitted as standard, they could order it from an option list; it was essentially the same approach as used for most of Chrysler’s other ranges.  Accordingly, the leather trim and many of the power accessories joined air-conditioning on the option list.  The base engine was now running a single four barrel carburetor although for and additional US$375, the Sonoramic could be ordered and combined with Chrysler’s new, robust four-speed manual transmission.  Surprising some observers, the convertible coachwork made a return to the catalogue.  All that meant the 300K could be advertised for US$1000 less than the 300J and the market responded in a text book example of price elasticity of demand, production spiking to 3647 (3,022 coupes & 625 convertibles).

1965 Chrysler 300L (four speed manual).

Despite the stellar sales of the 300K, even before the release of the 300L, the decision had been taken it would be the last of the letter series.  The tastes of those who wanted high performance had shifted to the smaller, lighter pony cars and intermediates which hadn’t even been envisaged when the C-300 had made its debut a decade earlier.  Additionally, the letter series had outlived their usefulness as image-makers for the corporation now they were no longer the fastest machines in the fleet and production-line rationalization meant it was easier and more profitable to maintain a single 300 line and allow buyers to choose their own combination of options; in other words, after 1965, it would still be possible to create a letter series 300 in most aspects except the badge and the now departed Sonoramics of fond memory.  When the last 300L was produced it was configured with a single four barrel carburetor and had it not been for the badges, few would have noticed the difference between it and any other 300 with the same body.  The lower price though continued to attract buyers and in its final year 2845 were sold (2,405 coupes & 440 convertibles).

Asymmetric

Asymmetric (pronounced a-sim-et-rick)

(1) Not identical on both sides of a central line; unsymmetrical; lacking symmetry.

(2) An asymmetric shape.

(3) In logic or mathematics, holding true of members of a class in one order but not in the opposite order, as in the relation “being an ancestor of”.

(4) In chemistry, having an unsymmetrical arrangement of atoms in a molecule.

(5) In chemistry, noting a carbon atom bonded to four different atoms or groups.

(6) In chemistry (of a polymer), noting an atom or group that is within a polymer chain and is bonded to two different atoms or groups that are external to the chain.

(7) In electrical engineering, of conductors having different conductivities depending on the direction of current flow, as of diodes

(8) In aeronautics, having unequal thrust, as caused by an inoperative engine in a twin-engined aircraft.

(9) In military theory, a conflict where the parties are vastly different in terms of military capacity.  This situation is not in all circumstances disadvantageous to the nominally inferior party.

(11) In cryptography, not involving a mutual exchange of keys between sender a7 receiver.

(12) In set theory, of a relation R on a set S: having the property that for any two elements of S (not necessarily distinct), at least one is not related to the other via R.

1870–1875: The construct was a- + symmetric.  The a- prefix was from the Ancient Greek - (a-) (ν-) (an- if immediately preceding a vowel) and was added to stems to created the sense of "not, without, opposite of".  The prefix is referred to as an alpha privative and is used with stems beginning with consonants (except sometimes “h”); “an-“ is synonymous and is used in front of words that start with vowels and sometimes “h”.  Symmetric was from the Latin symmetria from Ancient Greek συμμετρία (summetría).  Symmetry was from the 1560s in the sense of "relation of parts, proportion", from the sixteenth century French symmétrie and directly from the Latin symmetria, from the Greek symmetria (agreement in dimensions, due proportion, arrangement", from symmetros (having a common measure, even, proportionate), an assimilated form of syn- (together) + metron (measure) from the primitive Indo-European me- (to measure).  The meaning "harmonic arrangement of parts" dates from the 1590s.  The suffix -ic was from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European -kos & -os, formed with the i-stem suffix -i- and the adjectival suffix -kos & -os.  The form existed also in Ancient Greek as -ικός (-ikós), in Sanskrit as -इक (-ika) and the Old Church Slavonic as -ъкъ (-ŭkŭ); A doublet of -y.  In European languages, adding -kos to noun stems carried the meaning "characteristic of, like, typical, pertaining to" while on adjectival stems it acted emphatically.  In English it's always been used to form adjectives from nouns with the meaning “of or pertaining to”.  A precise technical use exists in physical chemistry where it's used to denote certain chemical compounds in which a specified chemical element has a higher oxidation number than in the equivalent compound whose name ends in the suffix -ous; (eg sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulphurous acid (H₂SO₃).  Asymmetric & asymmetrical are adjectives, asymmetricity, asymmetricality, asymmetricalness & asymmetry are nouns and asymmetrically is an adverb; the noun plural is asymmetries.

The usually symmetrically attired Lindsay Lohan demonstrates the possibilities of asymmetry.

1975 Kawasaki 750 H2 Mach IV.

Manufacturers of triple-cylinder motorcycles traditionally used single (3 into 1) or symmetrical (3 into 2) exhaust systems (although, during the 1970s, Suzuki offered some of their "Ram-Air" models with a bizarre 3 into 4 setup, the centre cylinder’s header bifurcated) but in 1969 Kawasaki adopted an asymmetric addition for one of the memorable machines of the time.  The Kawasaki 500 H1 Mach III had two outlets to the right, one to the left and was a fast, lethally unstable thing which was soon dubbed the "widow maker".  Improvements to the Mach III made it a little more manageable and its successor, the 750 H2 Mach IV was claimed to be better behaved but was faster still and best enjoyed by experts, preferably in a straight line although, with a narrow power band which peaked with a sudden rush, even that could be a challenge.  The Kawasaki triples remain the most charismatic of the Japanese motorcycles.

1973 Triumph X-75 Hurricane.

Available only during 1972-1973 and produced in small numbers, the Triumph X75 Hurricane was typical of the motorcycles being produced by the British manufacturers which had neglected development and re-investment and consequently were unable adequately to respond to the offerings of the Japanese which had done both aplenty.  Whatever their charms, models like the X75 were being rendered obsolescent, some of the underlying technology dating back decades yet, without the capital to invest, this was as good as it got and some of the fudges of the era were worse.  The X-75 was however ahead of its time in one way, it was a “factory special”, a design influenced by what custom shops in the US had been doing as one-offs for customers and in the years ahead, many manufacturers would be attracted by the concept and its healthy profit margins.  The X-75 is remembered also for the distinctive asymmetric stack of three exhaust pipes on the right-hand side.

1986 Ferrari Testarossa (1984-1991) with monospecchio.

Some of Ferrari's early-production Testarossas were fitted with a single high-mounted external mirror, on the left or right depending on the market into which it was sold and although the preferred term was the Italian “monospecchio” (one mirror), in the English speaking-world it was quickly dubbed the “flying mirror" (rendered sometimes in Italian as “specchio volante” (a ordinary wing mirror being a “specchietto laterale esterno”, proving everything sounds better in Italian)).  The unusual placement and blatant asymmetry annoyed some and delighted others, the unhappy more disgruntled still if they noticed the vent on right of the front spoiler not being matched by one to the left.  It was there to feed the air-conditioning’s radiator and while such offset singularities are not unusual in cars, many manufacturers create a matching fake as an aesthetic device: Ferrari did not.  The mirror’s curious placement was an unintended consequence of a European Union regulation (and it doubtful many institutions have in a relatively short time created as many regulations of such collective length as the EU) regarding the devices and this was interpreted by the designers as having to provide 100% rearward visibility.  Because of the sheer size of the rear bodywork necessitated by the twin radiators which sat behind the side-strakes (another distinctive Testarossa feature), the elevation was the only way this could be done but it later transpired the interpretation of the law was wrong, a perhaps forgivable mistake given the turgidity of EU legalese.

The Blohm & Voss BV 141

Focke-Wulf Fw 189 Eurl (Owl)

In aircraft, designs have for very good reason (aerodynamics, weight distribution, flying characteristics, ease of manufacture et al) tended to be symmetrical, sometimes as an engineering necessity such as the use of contra-rotationg propellers on some twin-engined airframes, a trick to offset the destabilizing effects of the torque when very potent power-plants are fitted.  There has though been the odd bizarre venture into structural asymmetry, one of the most intriguing being the Blohm & Voss BV 141, the most distinctive feature of which was an offset crew-capsule.  The BV 141 was tactical reconnaissance aircraft built in small numbers and used in a desultory manner by the Luftwaffe (the German air force) during World War II (1939-1945) and although it was studied by engineers from many countries, none seem to have been inspired to repeat the experiment. The origin of the curious craft lay in a specification issued in 1937 by the Reichsluftfahrtministerium (RLM; the German Air Ministry) which called for a single-engine reconnaissance aircraft, optimized for visual observation and, in response, Focke-Wulf responded with their Fw 189 Eurl (Owl) which, because of the then still novel twin-boomed layout, encountered some resistance from the RLM bureaucrats but it found much favor with the Luftwaffe and, over the course of the war, some nine-hundred entered service and it was used almost exclusively as the German's standard battlefield reconnaissance aircraft.  In fact, so successful did it prove in this role that the other configurations it was designed to accommodate, that of liaison and close-support ground-attack, were never pursued.  Although its performance was modest, it was a fine airframe with superb flying qualities and an ability to absorb punishment which, on the Russian front where it was extensively deployed, became famous and captured examples provide Russian aeronautical engineers with ides which would for years influence their designs.

The RLM had also invited Arado to tender but their Ar 198, although featuring an unusual under-slung and elongated cupola which afforded for the observer a uniquely panoramic view, proved unsatisfactory in test-flights and development ceased.  Blohm and Voss hadn't been included in the RLM's invitation but anyway chose to offer a design which was radically different even by the standards of the innovative Fw 189.  The asymmetric BV 141 design was eye-catching with the crew housed in an extensively glazed capsule, offset to starboard of the centre-line with a boom offset to the left which housed the single-engine in front with the tail to the rear.  Prototypes were built as early as 1938 and the Luftwaffe conducted operational trials over both the UK and USSR between 1939-1941 but, despite being satisfactory in most respects, the Bv 141 was hampered by poor performance, a consequence of using an under-powered engined.  A re-design of the structure to accommodate more powerful units was begun but delays in development and the urgent need for the up-rated engines for machines already in production doomed the project and the Bv 141 was in 1943 abandoned.

Despite the ungainly appearance, test-pilots reported the Fw 141 was a nicely balanced airframe, the seemingly strange weight distribution well compensated by (1) component placement, (2) the specific lift characteristics of the wing design and (3) the choice of opposite rotational direction for crankshaft and propeller, the torque generated used as a counter-balance.  Nor, despite the expectation of some, were there difficulties in handling whatever behavior was induced by the thrust versus drag asymmetry and pilots all indicated some intuitive trimming was all that was needed to compensate for any induced yaw.  The asymmetry extended even to the tail-plane, the starboard elevator and horizontal stabilizer removed (to afford the tail-gunner a wider field of fire) after the first three prototypes were built; surprisingly, this was said barely to affect the flying characteristics.  Focke-Wolf pursued the concept, a number of design-studies (including a piston & turbojet-engine hybrid) initiated but none progressed beyond the drawing-board.

Asymmetric warfare

In the twenty-first century, the term “asymmetric warfare” became widely used.  The concept describes conflicts in which there are significant disparities in power, capability and strategies between opposing forces and although the phrase has become recently fashionable, the idea is ancient, based often on the successes which could be exploited by small, mobile and agile (often irregular) forces against larger, conventionally assembled formations.  Reports of such tactics are found in accounts of conflicts in Asia, Africa, the Middle East and Europe from as early as reliable written records have been found.  The classic example is what came later to be called “guerrilla warfare”, hit-and-run tactics which probe and attack a weak spots as they are detected, the ancestor of insurgencies, “conventional” modern terrorism and cyber-attacks.  However, even between conventional national militaries there have long been examples of the asymmetric such as the use of small, cheap weapons like torpedo boats and mines which early in the twentieth century proved effective against the big, ruinously expensive Dreadnoughts.  To some extent, the spike in use of the phrase in the post-Cold War era happened because it provided such a contrast between the nuclear weapon states which, although having a capacity to destroy entire countries without having one soldier step foot on their territory, found themselves vulnerable to low-tech, cleverly planned attacks.

Although the term “asymmetric warfare” covers encompasses a wide vista, one increasingly consistent thread is that it can be a difficult thing for "conventional" military formations to counter insurgencies conducted by irregular combatants who, in many places and for much of the time, are visually indistinguishable from the civilian population.  The difficulty lies not in achieving the desired result (destruction of the enemy) but managing to do so without causing an “excessive” number of civilian causalities; although public disapproval has meant the awful phrase “collateral damage” is now rarely heard, civilians (many of them women & children) continue greatly to suffer in such conflicts, the death toll high.  Thus the critique of the retaliatory strategy of the Israel Defence Force (IDF) in response to the attack by the Hamas on 7 October 2023, Palestinian deaths now claimed to exceed 20,000; that number is unverified and will include an unknown number of Hamas combatants but there is no doubt the percentage of civilian deaths will be high, the total casualty count estimated early in January 2024 at some 60,000.  What the IDF appear to have done is settle on the strategy adopted by Ulysses S Grant (1822–1885; US president 1869-1877) in 1863 when appointed head of the Union armies: the total destruction of the opposing forces.  That decision was a reaction to the realization the previous approach (skirmishes and the temporary taking of enemy territory which was soon re-taken) was ineffectual and war would continue as long as the other side retained even a defensive military capacity.  Grant’s strategy was, in effect: destroy the secessionist army and the secessionist cause dies out.

In the US Civil War (1861-1965) that approach worked though at an appalling cost, the 1860s a period when ballistics had advanced to the point horrific injuries could be inflicted at scale but battlefield medical tools and techniques were barely advance from Napoleonic times.  The bodies were piled high.  Grant’s success was influential on the development of the US military which eventually evolved into an organization which came to see problems as something not to be solved but overwhelmed by the massive application of force, an attitude which although now refined, permeates from the Pentagon down to platoon level.  As the US proved more than once, the strategy works as long as there’s little concern about “collateral damage”, an example of this approach being when the Sri Lankan military rejected the argument there was “no military solution” to the long running civil war (1983-2009) waged by the Tamil Tigers (the Liberation Tigers of Tamil Eelam (LTTE)).  What “no military solution” means is that a war cannot be won if the rules of war are followed so the government took the decision that if war crimes and crimes against humanity were what was required to win, they would be committed.

In the 1990s, a number of political and military theorists actually advanced the doctrine “give war a chance”, the rationale being that however awful conflicts may be, if allowed to continue to the point where one side gains an unambiguous victory, the dispute is at least resolved and peace can ensue, sometimes for generations.  For most of human history, such was the usual path of war but after the formation of the United Nations (UN) in 1945 things changed, the Security Council the tool of the great powers, all of which (despite their publicity) viewed wars as a part of whatever agenda they were at the time pursuing and depending on this and that, that meant their interests sometimes lay in ending conflicts and sometimes in prolonging them.  In isolation, such an arrangement probably could have worked (albeit with much “collateral damage”) but over the years, a roll-call of nations run by politicians appalled by the consequences of war began to become involved, intervening with peace plans,  offering mediation and urging the UN to deploy “peacekeeping” forces, something which became an international growth industry.  Added to that, for a number of reasons, a proliferation of non-government organizations (NGO) were formed, many of which concerned themselves with relief programmes in conflict zones and while these benefited may civilians, they also had the effect of allowing combatant forces to re-group and re-arm, meaning wars could drag on for a decade or more.

In the dreadful events in Gaza, war is certainly being given a chance and the public position of both the IDF and the Israeli government is that the strategy being pursued is one designed totally “to destroy” not merely the military capacity of Hamas but the organization itself.  Such an idea worked for Grant in the 1860s and, as the Sri Lankan military predicted they would, end-game there was achieved in 2009 on the basis of “total destruction”.  However, Gaza (and the wider Middle East) is a different time & place and even if the IDF succeeds in “neutralizing” the opposing fighters and destroying the now famous network of tunnels and ad-hoc weapons manufacturing centres, it can’t be predicted that Hamas in some form won’t survive and in that case, what seems most likely is that while the asymmetry of nominal capacity between the two sides will be more extreme than before, Hamas is more likely to hone the tactics than shift the objective.  The IDF high command are of course realists and understand there is nothing to suggest “the Hamas problem” can be solved and being practical military types, they know if a problem can’t be solved it must be managed.  In the awful calculations of asymmetric conflict, this means the IDF calculate that while future attacks will happen, the more destructive the response now, the longer will be the interval before the next event.
