The 1980/2 Submarine movie "VIRUS" is on youtube.

[seaman hornsby]

A lot of free movies on youtube are blurry, this one is pretty clear.
The GUPPY submarine footage(about an hour and fifty minutes into it) are not a rehash of Ice Station Zebra/Assault on the Wayne/Murphy's War. But it appears to be fresh GUPPY
footage.

VIRUS 1980.
