The equipment consisted of some 200-240 aircraft, including Curtiss Hawk 75As, Fokker D.XXIs, Morane-Saulnier MS.406s, Gloster Gladiator IIs, Curtiss P-40M, LaGG-3, Fokker C.Xs, Westland Lysanders, VL Viima IIs, VL Myrsky IIs, Blackburn Ripon IIFs, and Bristol Blenheim Mk.Is.
In early 1942, two of the LaGG-1 and -3's designers, Semyon Lavochkin and Vladimir Gorbunov, attempted to correct this deficiency by experimentally fitting a LaGG-3 with the more powerful Shvetsov ASh-82 radial engine.
