- Official Navy register data for ATR-93: ordered under the Maximum War Effort program (Ord. 25 Feb 43); built by Levingston Shipbuilding Co., Orange, TX; keel laid 19 Apr 43; launched 11 Jun 43; never commissioned USN (Commiss. column '--'); struck 8 May 46; disposal recorded 8 Dec 43 (transferred). Ship note: 'Compl. 6 Dec 43, delivered the next day and trf. to UK under Lend Lease as FLARE. Returned to U.S. custody 13 Apr 46. Sold by FLC 24 Sep 46 to BOSEY (Board of Supply, Executive Yuan, China), merc. MING 101, then MING 301, scrapped 1960.'

- Shipscribe is a transcription project of official Navy register/Ships' Data publications, not the register scan itself. Transfer date reads 7 Dec 43 in NavSource and uboat.net vs 8 Dec 43 in this table's disposal column ('delivered the next day' after 6 Dec completion in the ship note - the 8 Dec figure likely records formal transfer paperwork). Contains no asbestos or materials information; supports no asbestos claim.

- Volunteer-compiled archive; milestones corroborated by the register transcription (ev-01), uboat.net (ev-03), and the Levingston yard table (ev-04). CAVEAT: the page's Specifications block (852 t light/1,315 t full, 165'6" length, Fulton triple-expansion steam engine, two Babcock & Wilcox boilers, complement 52) is the generic ATR-1-class block and conflicts with register-derived data for this steel Levingston-built group (143 ft, ~600/835 t, GM diesel-electric, complement ~43-45) - its machinery/dimension/complement figures are treated as misapplied class data and are NOT carried as this hull's fit; sister ATR-48's own NavSource page carries the correct diesel-electric block. 'Struck unknown' is superseded by the register's 8 May 46. No asbestos information; supports no asbestos claim.

- Identity correction: the tier-list label 'USS HMRT (ATR-93)' does not describe an actual commissioned U.S. Navy vessel named 'HMRT.' The hull carried no U.S. Navy name (number only), was never commissioned in the USN (register Commiss. column '--'; NavSource: 'never saw active service in the US Navy'; no ATR-93 entry exists in NARA's USN deck-log index, Special List 44 - consistent with absence of a USN commission), and 'HMRT' is the Royal Navy prefix His Majesty's Rescue Tug under which she was commissioned as HMRT Flare (W-151) on delivery day. NavalCoverMuseum's designation index lists her as 'ATR 93 - HMRT FLARE W-151 ex ATR 93.'

- Class/procurement context: the ATR 91-96 group (including this hull) originated as British Lend-Lease Requisition BAD-1750 for six '143-foot ocean-going salvage tugs'; VCNO directed construction of ATR 91-100 on 18 Jan 43 under the U.S. Maximum War Effort program; the Bureau of Ships contracted the group to General Motors Corporation, GM supplying diesel engines while subcontractors built the hulls (Levingston built ATR 91-96). Class design is Navy BAT-1: 600 t light / 835 t max, 143.0 ft oa x 33.8 ft e x 13.2 ft max draft, 1-3"/50 + 2-20mm armament, complement 43, 13 kts, 1,500 hp GM diesel-electric, single screw. The same 143-ft diesel-electric design family (Army Design 377, 'Tug, Ocean-Going, Diesel-Electric, Steel, 143 ft') built 18 Army sisters at Levingston on adjacent ways.

- asbestos_application
- Finding
- Era-level documentation: asbestos was used extensively as insulating and fireproofing material in U.S. WWII shipbuilding, and federal wartime policy reserved asbestos supply for shipbuilding programs. Applied to this hull only as inference: a 1943 steel-hulled diesel-electric tug of the BAT-1 design carried no boilers or main-steam lagging (unlike steam-plant sisters such as ATR-89), bounding era-typical asbestos applications to exhaust-line/muffler lagging, machinery gaskets and packing, electrical insulation and arc-resistant materials, accommodation-space insulation, and brake linings on towing and anchor machinery. Steel hull construction retains the possibility of structural fireproofing applications absent from wooden-hull sisters.

- Limitations
- Program/era scholarship applied to a class-typical plant - no source names this hull's actual outfit; no survey, drawing, or materials schedule for ATR-93 was located. Diesel-electric propulsion narrows the candidate scope versus steam sisters but does not eliminate it. Does not establish that asbestos was aboard, its quantity, location, condition, or any individual exposure; does not establish or defeat any claim of exposure or legal eligibility.

- NARA Ship Plan Index lists a Bureau of Ships microfilm plan for ATR-93 in Record Group 19 (National Archives Identifier 175668313) - the as-built drawing series under which a materials schedule could be sought. Corollary finding: NARA Special List #44 (USN deck-log inventory by ship number) contains NO ATR-93 entry - ATR-91 through ATR-96 are all absent while USN-commissioned sisters ATR-90 and ATR-97 through ATR-100 are present, consistent with this group never holding a USN commission; the vessel's operational logs, if extant, would be Royal Navy records in UK archives (ADM series).
