Development
The requirements of trying to develop an aircraft that should be easy to build fast and cheap, the designer Vladimir Jazenko. Jazenkos design should consist of kunstharzgetränktem birch wood, which was known for his good form and workability. Semyon Lavochkin chose for his competition designs LaGG -1 and LaGG - 3 also this material.

Nevertheless, an order for 30 aircraft was abandoned and built another prototype, this time with a 1100 hp M- 87B engine. The trial began in August 1939, with 576 km / h top speed have been achieved. Ultimately, however, only five production models were produced because of not properly functioning engine. Even were already in other types of testing that were classified as better.
