48*3" AAA shells
Advanced high-altitude interceptor in original configuration. To fulfill this role, (imprisoned) design team equipped the '100' (spells in Russian as STO) with two pressure cabins and TK-2 turbosuperchargers (two on each engine). Pilot occupied front cabin, gunner and navigator - the rear one. Both pilot and navigator had set of controls.
Initial armament was pure fighter-style:
Already on design stage pressure from Military resulted in a 'dive bomber bias' in the aircraft construction. In addition to offensive and defensive barrel weapons, '100' got underwing hardpoints for two bombs (up to 500kg each). Unusual armament was carried inside: two clips with 24 3inch AA-artillery shells with pre-set explosion altitude. Those shells could be used against both ground and aerial targets.
Project was approved for blueprints in mid- 1939, aircraft was ready in the end of the same year. Flight tests started on December 22, 1939 (pilot P.M.Stefanovsky). In Spring 1940 almost identical second '100' was delivered for trials. On May 1, 1940 '100' performed over Red Square at Moscow during The Worker's International Solidarity Day demonstration.
But after visit of Soviet delegation to Germany (and study of German military air doctrine) all changed for the '100'. High altitude long range interceptor was not a priority anymore. In May 1940 V.M.Petlyakov received an order to redesign '100' into front line dive bomber in 1.5 months. Order was supported by about 300 of personal, transferred from A.S.Yakovlev, S.V.Ilyushin, A.A.Arhangelsky and other teams. Confidence in the aircraft was so solid that no prototypes were built, blueprints were sent directly to factories for mass-production.
