 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. Because of the tight deadline, the components for the two incomplete prototypes were turned over to Factory No. 301 at Khimki, the new headquarters for the Lavochkin OKB, for assembly by Factory No. 381. Factory No. 21 in Gorky joined the program with three more aircraft built in record time with support from Factory No. 301. Tooling was constructed in 5 – 10 days with the first aircraft completed in a week and a half.
