Moray departed Philadelphia 31 January 1945, arriving New London, Connecticut, 1 February (The Moray accidentally rammed a coal barge Annapolis; there were no deaths.).[7][8] After shakedown training there and off Newport, Rhode Island, Moray left New London with Carp (SS-338) and Gillette (DE-681) 14 April for Balboa, Panama, C.Z., arriving 25 April. Underway 5 May, Moray arrived Pearl Harbor 21 May for final training, after which she sailed for the Marianas 7 June, arriving Saipan 20 June.
The submarine cleared Saipan 27 June for her first war patrol as the senior unit of a coordinated attack group including Sea Poacher (SS-406), Angler (SS-240), Cero (SS-225), Lapon (SS-260), and Carp (SS-338). Comdr. Barrows in Moray assigned stations when the group reached its patrol area off Tokyo 1 July. The first phase of this patrol centered on lifeguard duty. From 7 July to 9 July Moray's special mission was service as picketboat southeast of Honshū in preparation for 3rd Fleet bombardment. Then she continued lifeguard operations.
By June 1945, successful American submarine operations had made enemy targets almost nonexistent, and lifeguard duty became a vital mission for American submarines. However, Moray did get a chance at some action, when she and Kingfish (SS-234) attacked a convoy off Kinkazan, Honshū, 10 July. Allowing Kingfish to attack first, Moray then moved in to fire six torpedoes, then pulled out to rearm and permit Kingfish a second stab. A few moments later one of Moray's torpedoes hit a whaler "Fumi Maru No.6" {361 GRT}.[9] No other shipping was sighted; on 16 July the patrol was shifted to the Kurile Islands. Moray completed her patrol at Midway 6 August 1945.
