The Fw190 was one of the most famous fighter aircraft of the German Luftwaffe. The A-8 version was produced in greater numbers than any other. The A-8/R11 version was also used as a night fighter.
A new model with different equipment. Most important were parts of the MW 50 injection system, used for short term engine power boost. A cylindrical tank of 118 liters capacity was mounted in the rear fuselage. In an emergency, it could be used as additional fuel tank. Tank installation shifted the center of gravity backward and, as a cure, the under-fuselage mounted ETC 501 bomb rack was moved 20 cm forward. This rack became a standard from the A-8 model. The plane was equipped with a FuG 16 ZY radio set that despite the circular radio navigation antenna Morane antenna, was mounted under the left wing. The outstanding element for differentiation between the A-7 and A-8 is the Pitot head moved from mid-wing leading edge to right wing tip. The Fw 190A-8, like previous models, could be equipped with different Rustsatz kits: R1, R2, R3, R4, R6, R7, R8, R11, R12; but R1, R3 and R4 were abandoned shortly thereafter and generally R2, R6, R7 and R8 kits were used. Some of the R11 and R12 modifications produced in small quantities had small differences in the equipment (e.g. MG 131 machine guns tube was covered by a plate for reflection limitation, some got more the more efficient BMW 801 TU engines and FuG 125 Hermine radio navigation device). The variant with radar most often had a FuG 218 Neptune J-3 device.
The FW-190A-8/U-11 would carry a BT 700 (700KG/1,543lb) torpedo. It was used against the Russian Black Sea Fleet in February 1944.
SG 113 Zellendusche – 3-tube battery based on the MK 103 cannons mounted in the rear fuselage. Firing was made by a photosensor impulse. – SG 117 Zellendusche – 6-tube modification of the previously described battery.
Rohrblock 108 – similar construction with 7 tubes based on the elements of the MK 108 cannon, fired by photosensor impulse. Probably, it consisted only of MK 108 cannons barrels with a single cartridge; after firing of the first barrel others were fired automatically by the recoil force of previous barrel. This kind of armament was used for bombers interception and was tested on the Fw 190A-8 (W.Nr. 733713), prototype designation V74.
SG …? Harfe – set of 3-4 15-barrel, unguided 20 mm missile launchers mounted in the rear fuselage on both sides. At least one prototype plane had such armament and was presented to Gen. Adolf Galland.
Ruhrstahl X-4 (Ru 334)- wire guided rocket missiles mounted on underwing racks, probably of the ETC 503 type. This armament was developed for destroying ground targets (tanks) and for bombers fighting (different warhead). It was tested on the F-8 version plane.
From 1944, production of fighter planes was sharply increased (so-called Jagernotprog ramm). This required higher production coordination and development of a cooperative network. As a result, the Fw 180 A-8 was produced in mass numbers in nearly all Focke-Wulf affiliated factories (production started also in Cottbus, Sorau, Poznan). A licence was sold to the NDW (Norddeutsche Dornier Werke) factory in Wismar. Smaller factories performed repair work and recycled the planes withdrawn from service units. They also produced smaller aeroplane parts. Special coordination committees secured efficient work systems and continuous parts delivery. As the result 1334 A-8 series planes were built.
