Also worked on SONAR, really interesting stuff. Had a 1,8m high bay full of
processors, detecting ship's propeller noise. Each one had the sound of a
known ship's prop stored in ROM and did a correlation to find which ship it
was. Also did some work on the fire control for the torpedo's. those had a
speed of 24 knots, while the Russian nuclear sub had been clocked at 50, so
the subs could do circles around the torpedos.
The other thing about Batteries. And big manufacturer now does HALT
testing highly accelerated life testing) to prove the life of components, it
is all proven science, you can prove a lifetime of 10 years in a test taking
3 months.

Yea, so true. The Navy got so frustrated that they abandoned static analysis
for real-time testing.
I worked on linear beam forming for subs. We used card-edge scan testing
during retrace time, when the virtual beam was essentially scanning back
through the hull. Each bus interface unit had a Motorola 68000 on it, just
to control the testing, 60 times a second.
