Tachikawa Ki-74 PATSY

From 1937 Tachikawa produced a number of interesting designs which did not go into series production. These included the TS-1 single-seat ultra-light low-wing cabin monoplane; the R-38 two-seat parasol-wing monoplane primary trainer; the SS-1 twin-engined low-wing monoplane developed from the Lockheed 14 and intended for high-altitude research; the Ki-70 twin-engined high-speed reconnaissance monoplane; and the A-26, later redesignated Ki-77, a long-distance record aircraft with a remarkably slim fuselage and finely tapered wide-span monoplane wings. However, it was the Tachikawa Ki-74 monoplane which attracted the greatest official support. By 1941 the project had been confirmed as a long-range high-altitude bomber reconnaissance aircraft, and the first of the prototypes, powered by 1641kW turbocharged Ha-211-Ru radials, flew in March 1944. Thirteen pre-production machines followed, powered by more reliable 1491kW Ha-104 Ru engines, giving a maximum speed of 570km/h at 8500m. They carried 1000kg of bombs and were defended by a single remotely-controlled 12.7mm machine-gun in the tail. Although not used operationally, the Ki-74 received the Allied codename 'Patsy'.

This plane was equipped with a copy of a Norden bombsight and a search radar. The 8000km range is short compared to the Ki77 world distance record plane which flew 16,435km (and still had 800 liters in the tank upon landing), on which the design was based .

I dislike asymmetric cockpits as here and on some Canberras; it hurts the eye.

The Ju388 is comparable, but the Ki-74's 8,000 km range is unbelievable.

Interesting design:) I don't see any similarity do B-17:) Even if we start spook about "he has a tail, so it is similarity to B-17";)
