Works on the "Objects 4302 and 4303" started in 1944, when I.F.Florov was assigned a position of the Aircraft Department N°43 Head at NII-1. Those experimental planes were intended for transsonic speed trials at high altitude.
Aircraft were of all-metal construction. Maximum diameter of cigar-shaped fuselage was 1150mm. Towing hook was installed under the nose. The wing had thickness 13% and laminar flow profile (TsAGI, Svischev). Its tips had 45° dihedral to improve aircraft stability.
The most complex part of the aircraft was the landing gear. First flights were performed with simple fixed landing gear (wheels from the La-5). Later it was replaced by retractable metal ski and tail skid for landing. Simple wielded three-wheeled cart for takeoff. It was released once the ski was retracted.
According to other sources, the first prototype was flown as a glider with fixed landing gear, second and third made powered flights in 1947, Tests of aircraft were conducted by Heroes of the USSR Pakhomov and Yakubov.
After 20 flights (only one powered) were performed, all tests were cancelled. With progress of turbojet engines, interest in the fuel-hungry rocket powered fighters gradually faded. In 1948, the Aircraft Department at NII-1 was closed. The engine from the aircraft N°3 was used on Mikoyan I-270.
