“Fig Jar” datalink

(USSR)

Notes: This device was called “second captain” by Soviet sailors. Fitted to smaller ASW-oriented ships, it allowed them to execute coordinated ASW attacks. The system interlinked with the radar, helm, and fire control systems. When a coded burst was transmitted by one ship through the “Slim Net” radar, other ships with “Fig Jar” activated would automatically change course and speed, and if in range, automatically engage the target with a RBU-6000 attack.

The “Strut Curve” and later radar systems allowed both transmission and receipt of the coded burst, and thus by the 1980s “Fig Jar” began disappearing from the Soviet fleet. It is no longer in service aboard any ship.
