The design was completed quickly, but the construction of the five flying prototypes was protracted by the factory's inexperience in building metal aircraft.

The Lavochkin OKB was ordered to design a fighter using a single Junkers Jumo 004B axial-flow turbojet in February 1945.

381 by the end of August, but the prototypes were delayed because the plant had no experience building metal aircraft and lacked the necessary tooling.

[3] By the end of the year, the factory had only managed to complete a single airframe for static load testing.

This showed that the rear fuselage, wings and tail needed to be reinforced, and the opportunity was taken to enlarge the vertical stabilizer as well.

[5] The following day, the Council of Ministers ordered that a small batch of jets from each OKB were to participate in the 7 November parade commemorating the October Revolution.

Special three-wheeled trailers were built and the aircraft were driven to Moscow, but the flypast was cancelled because of bad weather.

The fuel capacity was increased to 660 kilograms (1,460 lb), the cockpit was widened by 80 centimeters (31 in) and fitted with an ejection seat.

Fore and aft armor plates were fitted to protect the pilot and a new radio aerial mast was installed.

Given that a higher-performance design, the Aircraft 156, had already been submitted for state acceptance trials, Semyon Lavochkin decided not to continue the development of the 150M.

Nevertheless, Lavochkin decided not to submit the 150F for state acceptance trials as the fundamental design flaws of the airframe still had not been resolved.
