Mooring at the
Todd Shipyards Corp. the next day,
Bull began her conversion to a
fast transport. Redesignated
APD-78 on 31 July 1944 and reconfigured to berth troops amidships and to carry their associated gear, the warship lost her "main battery" of three guns and received a single gun, in an enclosed mount forward. Newer, heavier 40 mm
Bofors anti-aircraft guns replaced the older mount. Getting underway in her new guise on 26 October 1944 and heading for Norfolk,
Bull carried out her shakedown training in the
Chesapeake Bay region under the aegis of the Amphibious Training Forces,
Atlantic Fleet. After clearing the
Virginia Capes on 7 November, the warship transited the
Panama Canal on 13 November and proceeded – via
San Diego and
San Pedro, California – to
Pearl Harbor. There, she embarked
Underwater Demolition Team-14 (UDT-14) on 7 December and sailed four days later, via
Eniwetok and
Ulithi, to the
Palaus, the staging area for the
invasion of Luzon.
Bull sortied on
New Year's Day 1945 with the beach demolition group. Proceeding via the
Surigao Strait,
Mindanao Sea, and the
South China Sea to
Lingayen Gulf, the fast transport and her companions suffered nearly continuous attacks by Japanese
kamikaze planes bent on destroying themselves and their targets. On
"S 2" day,
Bull provided fire support for the reconnaissance of the
San Fabian sector of Lingayen Gulf, earning praise from the commander of her embarked UDT for her "excellent and accurate" gunfire that kept enemy fire to a minimum. During her time in Lingayen Gulf,
Bull experienced some "close shaves". On one occasion, antiaircraft fire slapped down a suicider bent on crashing her just short of her side. Another time, a bomb landed less than away on her starboard quarter. While retiring from Lingayen Gulf to
Leyte as part of Task Unit 77.15.5 (TU 77.15.5),
Bull watched an American plane crash on nearby
Siguijori Island thought to be occupied by the Japanese. Detached to rescue the pilot,
Bull, guided by two Vought
F4Us, proceeded to the area and found the plane off the beach on the northwest side of the island. Sending armed landing parties in two of her boats,
Bull soon spotted crowds of native Filipinos coming out to greet the American sailors. The fast transport's men quickly learned that Filipino forces had driven the Japanese invaders from the island in November. She took the injured pilot on board, treated his wounds, and then sent him off in a
PBY. After a brief stop at Leyte, Bull reached Ulithi to prepare for the
invasion of Iwo Jima. On 10 February 1945, she cleared the
Carolines as part of TG 52.4, the Underwater Demolition Group of the Amphibious Support Force, Task Force 52 (TF 52). She headed, via
Saipan, to
Iwo Jima and arrived there three days before the landing.
Bull took part in the reconnaissance of both preferred and alternate beaches and drew Japanese fire several times, yet she escaped without damage on each occasion, despite several near misses. After "D day",
Bull operated as a screening vessel, while her embarked UDT cleared beaches to facilitate the landing of supplies. Although the ship's company suffered no casualties, one of UDT-14's officers was killed when a Japanese shore battery sank the
LCI in which he had embarked for gunfire spotting. Leaving Iwo Jima on 5 March,
Bull headed for Ulithi to make ready for the next major American
amphibious assault: the
invasion of Okinawa. She arrived off that island on 26 March and, but for short runs to Saipan for upkeep, remained there until after all organized Japanese resistance had been wiped out some three months later. Her principal duties during the campaign were to support beach reconnaissance and to screen other Allied ships. While off
Okinawa, she endured countless air raids, but no bullet or bomb ever touched her. On 4 June, while returning from Saipan,
Bull encountered the fringes of a
typhoon, which prompted the convoy to reverse course. Despite the course change, the ships in the formation experienced 70 knot (130 km/h) winds and mountainous seas. The storm subsided by mid afternoon; and, with no ships reporting any damage, the group resumed its course to Okinawa and arrived there on 8 June.
Bull spent the rest of June on a screening station near Okinawa before sailing for
Guam on 1 July. Continuing thence via Eniwetok and Pearl Harbor, the fast transport reached San Pedro, California, where she conducted voyage repairs, refresher training, and UDT rehearsals for the
invasion of the Japan. However, Japan's capitulation changed
Bulls next mission from invasion to occupation. After moving from San Pedro to San Diego in mid-August 1945, she sailed for the
Marianas on 6 September and reached Guam on 2 October 1945. Over the next few months, the fast transport operated in the
Philippine Islands, under the control of Commander, Philippine Sea Frontier. Her ports of call included:
Manila,
Samar, Leyte,
Subic Bay, and
Manus in the
Admiralties. She also visited Okinawa and made three voyages to
China. Ending her shuttle service in the Far East, she departed
Shanghai late in April 1946 and reached Pearl Harbor on 2 May. Three days later, she sailed with for southern California.
Bull was decommissioned at San Diego on 5 June 1947 and was placed in the
Pacific Reserve Fleet there on 16 June. There, she remained for almost two decades. Her name was struck from the
Navy List on 15 June 1966. == ROCS
