Ascends and descends in heli-
coidal pattern; recently
outfitted with new propulsion
system prior to moving from
California to East Coast of U. S.
for work with Naval Sound
Laboratory

Being designed

Under construction

Submarine for oceanographic
research at great depths

Put into service in 1967; has
120 cells outboard; built in
Santa Barbara

Sub can be carried piggy back
by a nuclear (mother) sub or
by Navy auxiliary ship rescue
vessel, DSRK-2 is expected to
be almost a carbon copy of
DSRV-1 now under construc-
tion; definite decision on
DSRV-2 design expected early
in 1968.

Atlantic; also used to place a
parabolic reflector to focus
sound between deep scattering
layer and array transducer for
U. S. Navy Underwater Sound
Laboratory
