Torpedoes
AST-53
The AST-53 (Anti-Schiffs-Torpedo - Anti-Ship-Torpedo) was a 550 mm calibre torpedo for use against surface ships. It was equipped with a passive acoustic homing guidance, the range of the homing system was about 800m. It was battery powered and used a gas-screening system to lower screw propellers noise. Primarily intended for the use from submarines.

AST-60
The AST-60 was a 350 mm calibre torpedo for use against submarines. They had an active/passive acoustic homing guidance, was battery powered and uses silver-zinc batteries. Special lightweight torpedo to be used from aircraft and smaller ships. The torpedo describes a circular path until the seeker finds a target. Can be used against submarines at up to 20 kn and depths down to 400m. Production was discontinued in 1990 after the AST-90 was put into service.
