- DANFS record for this hull: the second Quest was laid down 24 November 1943 by Gulf SB Co., Chickasaw, Ala.; launched 16 March 1944, sponsored by Mrs. O. R. Johnson; commissioned 25 October 1944, Lt. J. T. Riley, Jr., USNR in command. After fitting out/training/shakedown she sailed for Portland, Maine 21 December 1944 for duty with CTG 23.9 (antisubmarine exercises), departed for Norfolk 29 December, and on 4 January 1945 departed for the Canal Zone en route to the Pacific Fleet, escorting Coronis (ARL-10) and Kaweah (AO-15). Arrived San Diego 24 January; school ship at the Naval Small Craft Training Center, San Pedro from 1 March (interrupted by target-towing at San Diego); detached 20 August, arriving Pearl Harbor 28 August. Departed 3 September as part of TU 10.15.16 via Eniwetok and Saipan to Okinawa (arrived 3 October); minesweeping in/around Okinawa and southern Japan until 5 November, then the East China Sea with Bauer (DM-26), Garland (AM-238), and Notable (AM-267); returned to Sasebo late November; minesweeping in Japan until 20 February 1946; escorted YMS-431 and YMS-439 to Eniwetok (arrived 12 March) and served as logistics support vessel while they swept for Operation Crossroads; sailed 23 March with YMS-57 for Subic Bay (arrived 11 April); decommissioned 2 May 1946. Struck from the U.S. Naval Vessel Register 29 September 1947; transferred to the Philippines 2 July 1948; converted to the Presidential Yacht, renamed Apo-21 and commissioned later that year; renamed Pagasa and 'has served under the names Santa Maria, Pagasa, and Mount Samat into 1970.' Two battle stars for World War II service. Spec block: dp. 650; l. 184'6"; b. 33'2"; dr. 10'9"; s. 14.8 k.; cpl. 104; a. 1 3", 2 40mm; cl. Admirable.

- The official 1945 BuShips register names QUEST, official number AM281, in the mine-sweeper tables: builder row dittoes Gulf Shipbuilding Corp.

GSB-8' (Cooper-Bessemer GSB-8) engine entry at 1,710 shaft horsepower with 'Nat. Sup.' (National Supply Co.) reduction gear. The AM214-311 class characteristics block (which includes AM-281) prints: 2 propellers, geared 'Diesel' drive with single reduction gears (the register distinguishes this from 'Diesel elec.'); length 184'6" o.a. / 180'0" w.l.; extreme beam 33'0"; limiting-draft displacement 945 tons; trial displacement 850 tons; trial speed 14.8 knots; limiting draft 9'9"; total accommodations 11 officers + 93 enlisted; armament 1 x 3"/50 cal.

- Official Philippine government record of this hull's post-transfer service: 'The second Apo was an Admirable-class minesweeper laid down on November 24, 1943 by the Gulf Shipbuilding Corporation in Alabama. On March 16, 1944, it was launched, and on October 25, 1944, was commissioned as the USS Quest (AM 281). She received two battle stars during World War II. It was decommissioned on May 2, 1946 and struck from the Navy register on September 29, 1947. It was renamed Dalisay when it was transferred to the Republic of the Philippines on July 2, 1948. It was then renamed Pagasa, by President Ramon Magsaysay, and again to Santa Maria by President Carlos P. Garcia, after his hometown. In 1959, it was replaced by the new presidential yacht, the Lapu-Lapu, but continued to serve as the alternate yacht. With the designation TK-21, it was renamed three times by President Diosdado Macapagal as the Corregidor (1963), Pagasa (1964), and Incorruptible (1965). However, the name was reverted to Pag-Asa (1966) and finally changed to Mount Samat by President Ferdinand E. Marcos in 1967. The ship was decommissioned on September 21, 1993 and sunk off Sangley Point.'
