   Finding

   A Navy Department Ships Section, Office of Public Information release dated 2 July 1946 (transcribed by NavSource as the ship's official U.S. Navy history) documents ATR-25's operational record: placed in commission 11 April 1944 at the F. L. Fulton Shipyard, Antioch, California; overall length 165 feet, 34-foot beam, 'standard displacement of 1400 tons'; LTjg R. L. Hernlen, USN, assumed command. Shakedown and repair along the coast between San Francisco and Los Angeles, 11 April-2 June 1944. Departed San Francisco 2 June 1944 for Manus Island - a 59-day voyage with fueling stops at Samoa, the Fiji Islands, and Espiritu Santo, prolonged by assistance to SS Luxenberg Victory aground on a coral reef in Neggele Levu Lagoon. From 1 August 1944 to 2 May 1945 operated throughout the Admiralty Islands under Commander Naval Operating Base, Manus: barge movement (to Finschhafen, Hollandia, Biak, Kossel Roads in the Palaus, and Leyte) and assistance to ships in distress (firefighting, rescuing survivors, salvage of grounded ships, retrieving lost convoy tows), including USS Honolulu, SS Don Marquis, USS Mount Hood, and USS Leopard; in the Don Marquis salvage the tug's four monitors delivering 4,000 gallons per minute extinguished the fire on the Liberty ship, saving the ship and a stated $2 million of cargo. Reported to the Samar-Leyte area 2 May 1945 under Commander Naval Operating Base, Samar; continued barge movement and distress assistance through 12 October 1945, including to SS David R. Francis, USS Randolph, and SS James Gordon Bennett. Transferred to Manila 12 October 1945 for harbor duty under Service Division 73, Service Squadron 7. Per the release, after 17 months as a 7th Fleet constituent the tug had alone salvaged 15 ships and barges and assisted in 7 more; in spring 1946 she returned to the U.S. East Coast and reported to the Charleston, S.C. Naval Shipyard for decommissioning and disposal by sale.

   Limitations

   Official 1946 Navy Department public-information release preserved via NavSource transcription - the closest thing to a DANFS entry for this hull (no DANFS entry exists). It is a public-relations summary, not an operational record: the '1400 tons standard displacement' conflicts with register figures (852 light / 1,315 full - logged in gaps), place-name spellings are garbled ('Neggele Levu', 'Kessell Roads'), and claims such as the $2M cargo value are as-issued. Its salvage totals (15 salvaged, 7 assisted) cover only the 17-month Western Pacific period to October 1945. No asbestos or material information.

   asbestos_application

   Finding

   Class/era inference for a wooden-hulled, steam-propelled rescue tug commissioned April 1944: the hull was built to a standard Navy BuShips design during the documented period of Navy-wide asbestos use in new construction. The propulsion plant - two Babcock & Wilcox 'D'-type boilers and a Fulton vertical triple-expansion engine with steam distribution piping - carries the era-typical asbestos applications of steam ships (boiler and steam-line lagging, gaskets, valve and pump packing, machinery-space insulation); the wooden hull removes hull-structure fireproofing typical of steel construction but not machinery-space applications; towing-winch brake linings and electrical insulation are also era-typical uses.

ATR-25 was built 1943-44 within that era, but the guide identifies no material aboard this hull. For this vessel the applicable filing paths are the ATR-25 hull file, the ATR-1 class file, and the QM contractor files for Fulton Shipyard; the hull's indexed plan sets (NAIDs 175661901, 175668245) are a concrete starting point.

The spaced variant "ATR 25" was deferred by fleet-wide pacing at research time (see search_ledger). The vessel carried no name other than the hull number in U.S. service.
