The Yatsenko I-28 was a 1930s Soviet single-seat fighter designed by Vladmir Yatsenko and first flown in 1939. The I-28 was a low-wing cantilever monoplane of mixed construction powered by a 900 hp (671 kW) Tumansky M-87 radial piston engine. It had an enclosed single-seat cockpit with a rearwards sliding canopy. The wing had an inverted-gull shape to reduce the length of the retractable main landing legs. The prototype was destroyed shortly after the first flight but an order was placed for 30 production aircraft. Also ordered was a prototype of an attack version, the I-28Sh. Although the first five production aircraft were completed the programme was cancelled in early 1940.
