Shturmovik

Shturmovik (pronounced sturm-oh-vic)

The Russia word used to mean “Ground Attack Aircraft”.

1939-1941: From the Cyrillic штурмовик (shturmovík) which in English is written sometimes as the simplified (phonetic) Stormovik or Sturmovik.  The word is a shortened form of Bronirovanni Shturmovik (Bsh) (armed stormtrooper) and was the generic term in Russia for aircraft designed for this role; in English it was a synecdoche for the Ilyushin Il-2.

A flight of Ilyushin Il-2s.

The definitive Shturmovik was the Илью́шин Ил-2 (Ilyushin Il-2), a remarkable platform which provided a template for future airframes of its type.  Over 36,000 were produced, an all-time record for combat aircraft and one more impressive still if the 7000-odd of its closely related successor (Ilyushin Il-10) are included, the family total thus close to 43,000.  Although not as ascetically unhappy as the infamously ungainly French bombers of the era, the Il-2 was not a delicate, elegant thing in the style of something like the Supermarine Spitfire or a muscular form like the North American P-51 Mustang and one popular nickname adopted by the Soviet infantry viewing from below was “hunchback” although those better acquainted with its construction and purpose preferred “Flying Tank”.

The idea of “flying tank” is a useful one to explore.  Many theorists in the early 1930s had advocated the use of low-altitude aircraft, flying at relatively slow speeds as the most effective weapon which could deliver ordinance with sufficient accuracy to neutralize tanks and other armored vehicles in battlefield conditions.  That implied the need for an airframe to both carry heavy weaponry and sufficient armor to resist attack from the ground and air, a combination judged impossible to produce because the engines at the time lack the power needed for such heavy machine.  The engines did during the 1930s became more powerful but the conceptual breakthrough was in the design of the airframe.  Previously, designers had done essentially what the nineteenth century naval architects did to make the early “ironclads”: attach additional metal plates over an existing lightweight structure.  Even at sea that limited performance but did (for a while) make the craft close to impregnable; it couldn’t however produce a military aircraft with its need for specific performance over different ranges.  The solution was to make the armor an integral part of the shell, protecting the crew, engine and fuel tank, the weight of this central unit some 700 kg (1540 lb), a number offset by not having also to support the weight of a conventional fuselage, the steel part of that having little supporting structure inside, the armor used as a structural member.  It was an approach which in the post-war years would be implemented in cars as the “safety-cell”, the central passenger compartment onto which the other components would be added.

Early in July 1941, some two weeks into Operation Barbarossa (the Nazi invasion of the Soviet Union), the Wehrmacht (the German armed forces) first became aware of the Shturmovik which initially they compared to the Luftwaffe’s (the German air force) Junkers Ju 87 (Stuka) dive-bomber which had been such an effective ground-forces support weapon in the conquest of Poland and then Western Europe, its limitations not exposed until it was deployed in the early days of the Battle of Britain (July-October 1940).  The Ju 87 could support a heavier bomb-load than the Il-2 but, equipped with automatic cannons, rockets, machine guns, and bombs, the Russian aircraft was much more lethal.  The Germans however quickly identified the weak points and that most had been rushed into service with pilots provided with neither adequate training or the tactics needed to protect each other in flight, especially during attacking runs.  Moreover, they lacked the optical sights needed accurately to aim their weapons and while the thick armor surrounded the pilot and engine, the structure behind the cockpit was plywood, highly susceptible to damage (tail-gunners suffered a death rate seven times that of the pilots because the gunner’s portion of the airframe was mostly of plywood).

Literally hundreds of Il-2s were lost to anti-aircraft fire or attacks by fighters, usually from the rear during bombing runs but, defying the expectations had infected the highest levels of the German political and military command, the Soviets were able to make good their losses of Shturmoviks and pilots, just as they were able to re-equip armored divisions with tanks, exceeding the capacity of the Germans ability to destroy formations.  As the war proceeded, the Shturmoviks increasingly came in waves and although the attrition remained high (the losses at a rate other allied forces would never have countenanced), the sheer weight of numbers meant the Soviets could overwhelm what were increasingly numerically inferior formations.  Noting the robustness of the Il-2, the Germans nicknamed them Betonflugzeug (concrete plane), acknowledging the ability to absorb punishment; others preferred Der Schwarze Tod (the Black Death).  The ability of the Soviet industrial machine to first maintain and later vastly increase production of things like aircraft and tanks was because of decisions taken by the Germans during the 1930s which afforded priority to create an air-force best suited to supporting brief, high-intensity conflicts (which came to be known as blitzkrieg (lightning war), thus the mass-production of small dive-bombers, medium-range light bombers and fighters rather than long-range strategic, heavy bombers.  As the Soviets moved their plant & equipment eastward (itself a remarkable achievement), the factories became immune from air attack as they were beyond the range of the Luftwaffe.  However, as the German advance stalled, production in Moscow resumed, increasing the available numbers and innovations appeared, one prototype even tested with a flame-thrower mounted in the nose.

Another innovation first delivered by the Shturmovik was the Protivo-Tankovaya Avia Bomba (Anti-Tank Air-Bomb; the PTAB), one of the predecessors of modern cluster munitions and similar in concept to the contemporary German two-kilogram Sprengbombe Dickwandig (SD-2) (butterfly-bomb).  In Mid-1943, knowing the Wehrmacht’s Unternehmen Zitadelle (Operation Citadel) against Soviet forces in the Kursk salient was imminent, the Russians stockpiled the PTABs, producing almost a million of the 2 Kg devices, designed specifically so a Shturmovik could carry almost 200, each with a “shaped charge” warhead able to penetrate the armor of even the best protected tanks.  The battle of Kursk (July 1943) was the biggest tank engagement ever fought and for days some 8000 tanks (3000 German, 5000 Soviet) ranged around a vast battlefield of swirling heat, dust and death and although visibility at times restricted the use of air-power, the PTAB equipped Shturmoviks damaged or immobilized a verified 419 enemy vehicles.

The Shturmovik concept was quickly adopted by other air forces and one was rapidly improvised by the UK’s Royal Air Force to counter the threat posed by tanks in the North African campaign.  By 1941 it was apparent the Hawker Hurricane was no longer suitable in its original role as an interceptor and fighter but it was a robust, reliable and easily serviced platform and it proved adaptable to the ground attack role.  By early 1942 deliveries had begun of the Mark IID Hurricane and equipped with a pair of under-wing mounted 40mm (1.6 inch) canon, it proved an effective counter to the Africa Corps’ tanks in the Western Desert as well as fulfilling a similar role in the Burma theatre against the even more vulnerable Japanese armor; in both places they were dubbed, with some accuracy: “tank busters”.  The effect of the 40 mm canons was such that when fired, they perceptibly slowed the plane in flight but pilots learned techniques to compensate.  So convincing were the results that a generation of heavy fighters either designed for or able to be adapted for the purpose, Hawker’s Typhoon & Tempest and Republic’s huge P-47 Thunderbolt all as famed as “tank busters” as for any other part they played in the war, especially noted for their role in the development of air-to-ground rockets.

Despite progress, notably the use of UAVs (unmanned aerial vehicles, often casually referred to as “drones”) Shturmoviks have remained an important component of military inventories and some years after the end of the First Gulf War (1990-1991), one of the first conspiracy theories to appear on the then novel WorldWideWeb concerned them.  It was claimed a study the Pentagon conducted (using as targets Iraqi tanks abandoned in the Kuwaiti desert) concluded blocks of concrete dropped from aircraft were just as accurate as bombs as well as being cheaper and easier to produce, while equally effective in disabling a tank.  The conspiracy theory claimed that suggestions the concept be pursued was vetoed by the “military-industrial complex” which made much money out of building anti-tank bombs.
