- ATR-51: ordered 17 Nov 1942; built by Colberg Boat Works, Stockton CA; keel laid 19 Jun 1943; launched 19 Feb 1944; commissioned 22 Jun 1944; decommissioned 27 Jun 1946; stricken 29 Oct 1946; turned over to Maritime Commission disposal 13 Jun 1948; MA sale awarded 18 May 1948 - ship note records the buyer as Hugo Neu Corp., New York. Class notes document the BuShips design intent: wooden hulls and simple triple-expansion steam machinery buildable by small yards outside the main Navy program; ATR 50-89 directed by VCNO 5 Aug 1942 under the Maximum War Effort (1799-Vessel) Program.

- Compiled secondary reference built from official Navy/MC records, not a digitized primary document; the class's gold-standard roster nonetheless. Does not establish any asbestos content - construction/disposal chronology only. Hugo Neu was a scrap dealer, making scrapping the probable fate, but no scrapping certificate was located.

- Commissioned USS ATR-51 22 Jun 1944 at Stockton CA, LTjg. A. L. Larson in command. Asiatic-Pacific campaign credits: Iwo Jima operation 18-25 Feb 1945; Okinawa Gunto operation 1-28 Apr 1945 - two battle stars; occupation service in the Far East 19 Sep 1945 - 5 Jan 1946. NavSource prints decommission/stricken dates unknown and 'disposed of in 1946, fate unknown.' Specification block: 852 t light / 1,315 t full; 165'6" x 33'4" x 15'6"; 12.2 kts; one 3"/50 DP, two single 20mm AA; complement 5 officers, 47 enlisted; propulsion one Fulton Iron Works vertical triple-expansion engine, two Foster Wheeler 'D'-type boilers 200 psi saturated, single screw 1,600 hp, two 60kW 120V DC turbo ship's-service generators; fuel 1,620 bbls NSFO.

Its laid-down date (10 Jun 1943) conflicts with ShipScribe/NavalCoverMuseum (19 Jun 1943); its 'fate unknown' is superseded by ShipScribe's MC sale record. No asbestos content - service chronology and machinery specification only.

- Finding
- Official Navy logistics history names this hull for casualty-response work: on 20 Nov 1944 at Ulithi, after the Japanese midget-submarine (kaiten) attack torpedoed fleet oiler Mississinewa (AO-59) - which 'blazed up immediately' with ~85,000 bbls fuel oil, 9,000 bbls diesel, and ~405,000 gal aviation gasoline aboard - fleet and rescue tugs fought the fire under voice-radio direction from Service Squadron Ten's operations office in Prairie, 'some operating up to the edge of the flames to reach survivors, others actually going alongside the ship'; 'the efforts of the tug Munsee, Lieutenant Commander J.F. Pingley, and the rescue tug ATR-51, Lieutenant A.L. Larson, were especially praiseworthy.'

[6]Consolidated era/design inference - documented propulsion plant (NavSource spec block: Fulton Iron Works vertical triple-expansion engine, two Foster Wheeler 'D'-type boilers 200 psi saturated, single screw 1,600 ihp) + documented BuShips design rationale and construction era (ShipScribe class notes) [other_primary]
- Locator
- NavSource 09/40/40051 propulsion/spec block; ShipScribe ATR-1 class notes
- Finding type
- asbestos_application
- Finding
- Era/design inference: this hull is a 1943-44 wooden-hulled Navy rescue tug built to the BuShips ATR-1 design with a genuine steam plant - two oil-fired Foster Wheeler 'D'-type boilers at 200 psi saturated feeding a vertical triple-expansion engine. Steam naval vessels of 1943-44 were lagged, gasketed, and packed with era-standard materials, which were commonly asbestos-containing: boiler and steam-drum insulation, steam-line lagging, valve and flange gaskets, machinery packing, accommodation joiner insulation, towing-engine/winch and windlass brake linings, and deck composition. Wooden hull construction does not reduce the machinery-space insulation load. Exposure-relevant populations if any material was present: Colberg Boat Works construction trades (Jun 1943 - Jun 1944); the wartime crew (~52) across Ulithi/Iwo Jima/Okinawa and occupation service (Jun 1944 - Jun 1946); whoever scrapped or refit the hull after the 1948 Hugo Neu sale.

No survey, specification, or material schedule naming ATR-51 was located; establishes no asbestos content, quantity, location, condition, individual exposure, or causation. Nothing is known of the hull's material state after the May/June 1948 sale.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and wartime construction program under which this hull was built at Colberg's Stockton yard. The USMC-commissioned 1944-45 industrial-hygiene survey of pipe-covering operations at Navy and contract yards documented that 'an important ingredient of pipe covering material used on U.S. Navy vessels is amosite.'

ATR-51 was ordered Nov 1942 and laid down Jun 1943 inside this procurement regime.
