Whilst conducting research related to increasing the T-60 Light Tank's armament power in February 1942, the staff of the experimental department of Factory #2 of the People's Commissariat of Armament, installed a 23mm gun into the T-60 turret. The 23mm gun was a modification of the Aircraft Gun VYa. The tank version turned out to be somewhat more effective than the aviation one, but the operational experience was short lived, because in 1942 there was not enough 23mm ammunition even for the IL-2 Ground Assault Aircraft. Lastly, the abrupt gun recoil jammed the tank's turret. Altogether sixteen VYa guns were manufactured for the T-60 tank in March-April, it is unknown though if they were installed on any tanks.
