This is SILVERSIDES (SS-236), the first of the famous "Mare Island Trio" (along with sisters TRIGGER (SS-237) and WAHOO (SS-238)), as the boat appeared in August of 1944. SILVERSIDES is configured almost identically to TRIGGER at the same date; the two boats left Mare Island after overhauls in the same month. SILVERSIDES is camouflaged in the overall Dull Black (BK) of Measure 9.
SS-236 mounts the usual 4"/50-caliber Mark 12 wet mount forward, with a 20mm Oerlikon on the aft gun foundation. A single 40mm Bofors Mark 3 sits on the cigarette deck, with another 20mm Oerlikon mounted on the forward position of the fairwater. The SJ-1 surface search radar antenna (with its slotted grid reflector) sits on a mast ahead of the periscope shears, with SD aft. The JP line array hydrophone is just forward of the 4" gun.
SILVERSIDES survived the war to become a museum ship in Muskegon, Michigan.
Is their going to be one on the U.S.S. Silversides SS-236?
Are you continuing perhaps with Guppy I and II ?
My policy for all my drawing series so far is to stop at 1945 to ensure I have a reasonable goal to work towards. My work is always available to anyone who wishes to modify it into postwar versions.
