TsKB-54

Escort Aircraft

Ilyushin

There were other versions of the DB-3. In March 1938 it was submitted for state tests as an escort for long range bombers. The new variant had powerful armament consisting of a nose mounting with a ShVAK gun, an upper turret with a ShVAK gun, and an under fuselage mounting for a remotely-controlled ShKAS machine qun, installed on the pivoting fairing of a remote pylon underneath the fuselage centre section.

It was intended that by including the escort in a DB-3 formation it could use its guns to defend the bombers from attacks by enemy fighters. The aircraft did not go into production because it could not fulfil all the functions of the escort fighter.
