One operational event is recorded: during 21/22 December 1944, off Fremantle (Western Australia), YMS-72 under Lt. J.E. Reilly, USNR was among the escorts of a simulated convoy (frigate USS Corpus Christi, submarine rescue vessel USS Coucal, armed yacht USS Isabel, minesweepers HMAS Dubbo, HMAS Inverell, HMAS Mildura, HMAS Warrnambool, motor minesweeper USS YMS-11, motor launches HMAS ML 815 and ML 826) for convoy-attack exercises by submarines USS Besugo, USS Blackfin, and USS Hardhead; the two motor minesweepers and both motor launches parted company before the night exercises. uboat.net sources the entry to the Report of Proceedings of HMAS Mildura for December 1944 plus the war diary of USS Isabel for December 1944.

- The Weaver Shipyards production table lists 'YMS 72 | US Navy | Minesweeper | 278 (GT) | delivered 15-Jan-43 | Struck 1946'. The yard history records Joseph Weaver and Son founded 1897 (Joe Weaver and George Levingston) to build barges for the Galveston Navigation District, primarily a repair yard until WWII contracts for wooden minesweepers and sub chasers were awarded in 1941-42; renamed Weaver Shipyards on L. E. Weaver's death in 1941. The same yard built YMS 66-75 and 247-258 plus YMS 371-374 and sub chasers SC 666-667 - sisters YMS-70 foundered in the October 1944 typhoon off Leyte and YMS-71 was mined off Borneo in April 1945; YMS-72 survived the war (HyperWar loss-annotated list, ev-07).

- Class context for this hull: 'The wood-hulled YMS proved to be one of the U.S. Navy's more durable and versatile types' - 561 yard minesweepers were built at 35 U.S. yacht yards (12 East Coast, 19 West Coast, 4 Great Lakes) beginning with YMS-1, laid down 4 March 1941 at Henry B. Nevins, Inc., City Island, NY. 'YMS-1 through 134 had two stacks' - YMS-72 belongs to this early two-stack production group. Class-level specifications on the index: length overall 136', extreme beam 24'6", displacement 320 tons, max draft 6'1", complement 33, one 3"/50 dual-purpose mount and two 20mm mounts, designed speed 12 knots, General Motors 8-268A diesel engines on two shafts, designed shaft horsepower 880. Surviving YMS were reclassified as AMS and given bird names in 1947 - YMS-72, already struck and disposed overseas, never received one.

- Finding type
- historical_record
- Finding
- The official WWII engagement-star eligibility list credits 'YMS 72' with one operation: '21 Nov 45 - 24 Nov 45 | P207' - Minesweeping Operations Pacific, the post-surrender clearance of minefields across the Pacific areas (operation window 23 June 1945 - 2 March 1946 covering Honshu, Kyushu-Korea, East China Sea-Ryukyus, Hainan, and Yangtze approaches sub-areas). This is the hull's only engagement-star credit - consistent with a career spent on routine and clearance sweeping rather than assault-landing operations.

- The official occupation-service eligibility list credits 'YMS 72' with Navy Occupation Service Medal service '13 Oct - 13 Dec 45' carrying clasp 'A' (Asia - clasps 'Europe' and 'Asia' denote the service area per sec. 19 regulations), plus a further entry '14 Dec 45 - 6 Jan 46' in the China Service column - i.e., occupation duty in the Asiatic-Pacific area through mid-December 1945 and qualifying China-service presence into the first week of January 1946. This places the hull in or adjacent to Chinese territorial waters roughly eight to eleven weeks before she was struck (28 March 1946).

The first window opens on her completion/commissioning date (15 January 1943); the second runs through the end of the Pacific war. A six-month coverage gap (late November 1943 - May 1944) separates the two inventoried ranges - logs for that window are not in the holdings list (see gaps). These are log-coverage dates, not asserted commissioning/decommissioning dates. YMS-72 does not appear on NARA's list of digitized deck logs in the National Archives Catalog (the digitized YMS entries are the hulls later named under the AMS/MSCO program); the logs are an undigitized primary record covering most of her active career, including the December 1944 Fremantle period and the start of her postwar clearance service.

[11]Era inference built on: NavSource hull-page propulsion spec (two GM 8-268A diesels, reduction gear, two shafts - no steam plant); NavSource class index (wood-hulled YMS type); GAO HRD-80-2 Navy-wide asbestos-use documentation (ev-11) [other_primary]

- Finding type
- asbestos_application
- Finding
- YMS-72 was a wooden-hulled, diesel-powered auxiliary motor minesweeper - a materially different asbestos profile from steam vessels: no boilers, no turbines, no steam lines, so the dominant boiler/turbine-lagging pathway of larger combatants does not apply. Era-standard applications aboard a small wooden diesel combatant of this type and period were diesel-exhaust and muffler lagging, engine-room thermal/acoustic insulation, machinery gaskets and valve packing, electrical insulation, and winch/windlass brake linings. Her wood hull and small machinery spaces imply a substantially smaller insulation footprint than a steam combatant.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, or work package located for YMS-72. Names era-standard applications, not confirmed installed materials. No quantity, no manufacturer attribution, no ship-proven presence. The small craft's reduced systems footprint makes the inference weaker than for steam-powered hulls of the same era.

CourtListener exact-phrase hull-number opinion search returned zero results; the loose unquoted name queries surfaced only lexical false matches - Texas state-court criminal records whose scanned text produced token collisions - and an unclassifiable 1,892-result loose docket page of unrelated federal and state matters.
