The fate of the Focke-Wulf 190 on the Russian front perfectly summarizes the problems faced by the Luftwaffe itself. The Luftwaffe specialized in focusing numeric and qualitative advantage at a number of key points on the battlefield. In Russia the battlefield constantly expanded as the German Army forced itself east. Distances between key points increased with that expansion. The key points shifted from one part of the front to the next and the number of key points increased as the campaign progressed. The Luftwaffe broke up into smaller units in answer to the army’s calls for support, thus expending themselves in ‘penny packets’ and reducing their effectiveness. The primitive conditions existing on the airfields on the Russian front, together with the lengthening of supply lines stressed the sophisticated and sensitive structure of the Luftwaffe.
The Focke-Wulf 190, with its armament of four 20 mm cannon and two 7.92 mm machine guns arrived on the eastern front in late 1942 with the mission of combating the Il-2 armored ground attack aircraft. The legendary Fighter Wing 54, Green Heart, proved the machine’s usefulness on the Russian Front in the Leningrad sector.
At about that time the Luftwaffe learned the suitability of the Focke-Wulf 190 for fighter-bomber operations. Thus began a constant competition for the insufficient supplies of this aircraft. The aging Ju 87D found itself increasingly unable to defend itself against the swarms of Soviet fighters. So the Luftwaffe converted Stuka Wings to Attack Wings by replacing the Stukas with Fw 190 fighter-bombers. By late summer 1943 the Luftwaffe was re-equipping ground attack units at a rate of two every six weeks. Even the veteran interceptor wing, Fighter Wing 54, was converted to fighter-bomber duty.
The Focke-Wulf 190 was a sophisticated beast. Demand for this aircraft by increasing numbers of units, all with different requirements, resulted in a plethora of variants. The high demand and the number of variants complicated production and supply. The primitive conditions on the airfields challenged the maintenance crews on the front lines laboring to keep these sophisticated aircraft in combat capable condition.
I will touch on only a few of the many variants of this aircraft, stressing the mid-war fighter-bombers featured in the novel Cauldron. Please refer to my sources below for a complete list.
In 1942 production shifted from the Fw 190 A-3 to the A-4. Fighter-bomber variants coming out of the factories included the A-4/U-3 with additional armor plating for the engine and the cockpit and fittings for a 551 pound bomb or a 66 Imperial gallon drop tank under the fuselage. In the field the crews generally removed the outer two of the wing mounted 20 mm cannon to save weight. The A-4/U8 could retain the full gun armament and carry the drop tank under the fuselage and four 110 pound bombs on wing racks. If the two outer 20 mm guns were removed the aircraft could carry the drop tank under the fuselage and two 551 pound bombs on the racks under the wings. If the fuselage mounted machine guns were also removed and only the tw0 20 mm cannon in the wing roots were retained, the aircraft could carry the 551 pound bomb under the fuselage and two drop tanks under the wings. Variants only got more complicated from there.
The Focke-Wulf 190, like the Bf 109, served on all fronts. Its capabilities are well documented and make fascinating reading. Only a few sources are listed below.
