Yeah, spent many hours at NOSC/NRAD/what_ever_it_is_now using the real-
time "hybrid simulator" with an ADCAP torpedo panel in the loop. We 
shared the facility with the people working on the Mark 46/50 upgrades.

Dr. Robert Goddard of APL would probably be interested in communicating 
with you re: increasing the speed of the SST. I'll send you his email 
addy when I get to work later today.

Tom,

I was there managing the advanced lightweight project which funded the 
simulator upgrade.  (The advanced lightweight became the MK50).  I left to 
go to DC in '78.  Both ADCAP and MK50 continued well after that of course. 
Maybe we crossed paths... ?  I actually started my engineering career 
working on the hybrid simulator when it was a UNIVAC 1108 plus a couple of 
the largest analog computers in existence at the time - in Pasadena, CA 
which was a Navy / Caltech lab.  We moved / merged the lab in San Diego in 
'73.
