Barry, 13.06.2016 18:19 Twice as heavy, larger dimensions, more crew, greater armament the only difference being that there was only one Su-12 as opposed to 864 Uhu's. Originally conceived in 1943 it did not make it's first flight until 26th August 1947. Whilst it achieved and exceeded it's design and performance parameters there was no available manufacturing space, so a move was made to have it made in Czechoslovakia but this was turned down as the powers that be said it had "failed to achieve it's designed performance". You couldn't make it up could you? Power plant 2 x 1,850 h.p. Shvetsov ASh-82FN 14 cylinder radial engines. Span 70'9" Length 39'1" Height 18'2" Wing area 560 sq ft Empty weight 15,365 lb Loaded weight 19,485 lb Max speed 330 mph at 18,360 ft Range 710 miles Service ceiling 36,000 ft Armament 4 x 20 mm Berezin cannon, one firing upwards two in in upper turret and one in the tail turret. 1,765 lb bombs
