Battle of Okinawa

With UDT-4 embarked, Loy sailed for the Ryukyus on 21 March. While approaching Okinawa on 26 March, she fought off the first of many repeated enemy suicide plane attacks and shot down the attacker. Prior to the invasion, she conducted shore reconnaissance operations and supported shore demolition operations by UDT-4. On 29 March, she provided medical and salvage assistance to LSM(R)-188 after a kamikaze crashed her stern.

Loy boated UDT-4 off Purple Beach during landings on 1 April. During the next week she supported operations of the UDT and patrolled off Okinawa. After sailing to Kerama Retto on 10 April, she supported demolition operations on Ie Shima from 16 to 23 April. Despite intermittent enemy air attacks, she also continued coastal ASW patrols; her guns shot down an attacker on the 8th and downed another enemy aircraft on the 16th.

Departing Okinawa on 25 April, Loy arrived at Guam, Marianas on 2 May. From 11 to 15 May she returned to Okinawa as convoy escort and then began station patrols in the anti-aircraft screen. While on patrol on 25 May, she embarked and cared for survivors from Barry (DD-248) after the high speed transport had been hit by a kamikaze. Two days later, she shot down three suicide aircraft during two attacks. The third aircraft exploded close aboard the starboard beam and sprayed the ship with fragments. She suffered 18 casualties and some internal damage. While steaming for temporary repairs at Hagushi, Okinawa, she shot down yet another attacker early on 28 May after the aircraft had narrowly missed her stern.

Loy proceeded to Kerama Retto on 29 May for additional repairs; then from 7 to 19 June she steamed via Saipan to Leyte Gulf. She repaired battle damage until 28 July; operated out of Leyte Gulf until 10 September; and arrived at Lingayen Gulf, Luzon, on 13 September to escort transports carrying occupation troops to Japan. Departing on 20 September, she arrived at Wakayama Bay, Honshū, the 25th; and during the next month she served as screening ship in Wakayama Bay. After an escort run to Nagoya and back, she sailed on 31 October for the Philippines. She carried passengers and mail to Nagoya; refueled at Taku, China; and reached Manila Bay, Luzon, on 12 November. There she embarked troops for transportation to the United States. Loy departed Manila Bay on her homebound "Magic Carpet" run on 19 November. She touched at Samar, Eniwetok and Pearl Harbor and arrived San Diego on 11 November.
