Anyway, I think laser beams would attenuate pretty quickly in a
not-very-transparent medium like seawater. A supercavitating bullet
travelling at Mach 3? No problem ;-)

Seawater is moreor-less transparent to a properly tuned blue/green lasers, so
there would be little/no attenuation. No moving parts to corrode in the
saltwater, and no ejection ports to get gummed up by oceanic detritus.

...Seawater may be transparent to it, but seems to me all the stuffe floating in the water
from plankton to detritus would cause a problem. the dispersion from all the detritus
would prolly use up a great deal of the energy put into the laser just to plow thru it
all.
