Focke-Wulf TL Fighter with HeS Oil Flitzer
After numerous diverse project studies in 1943, the Focke-Wulf design bureau at Bad Eilsen concentrated on variants of their jet-fighter projects. Special importance was placed on a powerful twin-boom machine in the summer of 1944. The planned single-seater Flitzer was to be powered initially by a BMW 003 (as an intermediate solution), later by the HeS Oil, the standard engine with greater thrust. A turbo-prop (PTL 021) was also investigated. The aircraft would be capable of 900 km/hr (560 mph) and – depending on the powerplant – operate at up to 15,000 metres (49,000 ft). Endurance hoped for was at least one hour. Three different but easily produced weapons variants were to be offered: either an MK 103 and two MG 151/15s, or two MK 108s and two MG 151/20s, or four MK 213s in the fuselage and wings. The EZ 46
reflex gyro-stabilised gunsight was planned. Electronics were the FuG 15 ZY and an FuG 25a as an IFF unit for German flak. By the beginning of 1945 the design work was almost completed, as was the future equipment for the first series-produced aircraft, but the promised HeS Oil turbine never came, and substitutes had to be considered instead. The Allies captured the Focke-Wulf planning offices in April 1945, and came into possession of numerous plans, reports and drawings of the Flitzer, which would surely have been a very useful fighter aircraft.
