I was a Gun Fire Control Technician.  Actually, since we didn’t have guns on the boats. I was a Torpedo Fire Control Technician.  I took care of the computers that aimed and fired the torpedoes.


We did a pretty good job, too.   The Canopus, the Washington, and the Vallejo each earned the Battle Efficiency “E” Award while I was aboard.  The Vallejo also won COMSUBLANT’s “Super E” for 1979. Now, we just call it

“Bottom Gun.”

The Theodore Roosevelt and George Washington both had Mk 112 Mod 2 Underwater Fire Control Systems.  The Mk 112 system was completely analogue and needed a lot of alignment.
