I got a little knowledge on the EMSP. I seem to recall it never
reached deployment, but I find Internet references to it being the
standard acoustic platform at some point. I can't imagine 1980's
technology would be used even in 2000, much less now. I guess they
did some upgrades before it reached production.

Every single bare circuit board used on AN/UYS-2 was tested using
programs that I wrote. Back in the day.

Maybe you can help me understand. I was on the program when it first
got started. ATT got the contract to develop the hardware and it was
all fully custom ICs.

Yes. My employer.

I thought in the end the entire program was canceled.
But I find references that say it was the system used in the 90's
which is really surprising.

Did I hear wrong or was it just exaggerated? Where was this processor
actually used? I think it the program was started by the Navy for use
on submaries, so I assume they would have been the last user to stay
with the program.

The submarine world is now using mostly COTS hardware to perform these
functions.
