- Ship-specific record for ATR-27: ATR-1 class rescue tug laid down 13 Sep 1943 at Fulton Shipyard, Antioch, CA; launched 18 Jun 1944; commissioned USS ATR-27 1 Aug 1944, LTjg. Carl E. Kemmerer in command; decommissioned and stricken dates listed as unknown; 'disposed of in 1946, fate unknown.' Specifications: 852 t light / 1,315 t full; 165'6" x 33'4" x 15'6"; 12.2 kt; armament one 3"/50 DP mount, two single 20mm AA; complement 5 officers + 47 enlisted; propulsion one Fulton Iron Works vertical triple-expansion reciprocating steam engine, two Babcock & Wilcox 'D'-type boilers (200 psi, saturated), two turbo-drive 60 kW 120 V DC ship's-service generators, single propeller, 1,600 shp. Listed ribbons: American Campaign Medal, World War II Victory Medal. Page states 'There is no DANFS history available for USS ATR-27.'

- Limitations
- NavSource is a volunteer compilation transcribing official sources (Ships' Data, NVR), not an official publication. Its record omits the decommissioning/strike dates and truncates the disposal trail ('disposed of in 1946, fate unknown') that Shipscribe's MC-derived table carries to a 1948 sale. Ribbon listing is likely incomplete. Establishes the hull's identity and machinery but makes no statement about materials or insulation content.

- Per-hull rows for ATR-27: re-ordered to Fulton Shipyard 22 Jul 1942 (earlier order at Weaver Shipyards dated 19 Jun 1942); keel 13 Sep 43, launch 18 Jun 44, commissioned 1 Aug 44; decommissioned 9 May 46; stricken 22 Jan 48; MC disposal 21 Jul 48 (fate code MC/D - Maritime Commission disposal); MA sale awarded 17 May 48. Ship note: 'Proposed for Arctic service by CinCLant on 26 Mar 46 but on 3 Apr 46 CNO assigned ATA-217 as a replacement for ATR-27. Sold (awarded) by MC to Irving A. Germain, New York.'

- Limitations
- Shipscribe reproduces official BuShips/MC/NVR tables but is a private research compilation, not an official publication. The 1948 disposal detail conflicts with NavSource's coarser 'disposed of in 1946.' The Arctic-service proposal documents Atlantic Fleet (CinCLant) control of the hull by March 1946 but gives no location for the ship at that date. No materials or insulation content is recorded.

- ATR-1 class page, 'Class Notes' paragraphs 1-2
- Finding type
- vessel_history
- Finding
- Class/program record: on 12 Sep 1941 the Chief of the Bureau of Ships urged a rescue-tug service (seaworthiness, 1,500+ HP to tow large vessels at sea, towing engine, long radius, firefighting equipment, basic salvage stores) modeled on British experience; CNO directed construction of ATR 1-40 on 19 Jan 1942 under the Maximum War Effort (1799-vessel) program. To spare the main shipbuilding program the Navy 'decided to have the vessels built of wood and equipped with relatively simple triple expansion steam machinery,' letting small builders and local machine shops supply hulls and engines. One source attributes the design to the John G. Alden firm.

[5]Consolidated era/design inference applied to this hull's documented propulsion plant (NavSource + Shipscribe spec records, ev-01/ev-02): two B&W 'D'-type boilers (200 psi saturated) and a Fulton Iron Works triple-expansion engine in a 1944 wartime build [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference: a 1944-built single-screw steam rescue tug constructed under the emergency wartime program, when insulation products for marine steam plants commonly contained asbestos fiber. Typical applications for the type: boiler casing and drum insulation; steam-line lagging between boiler room and engine room; valve and flange gaskets; machinery packing; insulation felt around hot machinery in accommodation spaces. The wooden hull bounds the inference - no hull-structural insulation or joiner bulkhead system is implied, unlike steel combatants of the era.

- Limitations
- Class/era inference only - no ship-level asbestos record located for this or any ATR-1-class member. No product names, quantities, or surviving material are established for this hull; the wooden hull narrows but does not eliminate the plausible footprint (machinery spaces still carried a full steam plant). Does not establish exposure for any individual.

Coverage ends 30 Jun 1945; logs for the final ten months of commission (Jul 1945-May 1946) are not in this listing. A deck log would establish locations and movements but is unlikely to name insulation materials.

- Finding
- A transcribed NAVPERS-553 separation notice for a Machinist's Mate 3rd Class (USN-I, separated at USNPSC Shelton, VA; insurance discontinuance Feb 1946) lists his service vessels and stations in sequence: 'USNAB Espiritu Santo, New Hebrides; USS ATR-27.' This documents (a) an engineering-rating crew member assigned to this hull and (b) service at or after a South Pacific (New Hebrides) base assignment - consistent with the ship operating in the South Pacific area during 1945.

A single personnel record: it places one machinist's mate aboard but establishes nothing about materials aboard or any individual's exposure. Assignment sequence (Espiritu Santo preceding ATR-27) is read from list order, not dated entries.

- Finding
- A secondary barge-history compilation cites ATR-27's war diary for a single documented wartime operation: towing Army covered lighter BCL-3053 from Noumea to Bulari Passage, New Caledonia, on 3 Apr 1945. The compiler describes this as the only wartime activity record for ATR-27 located to date. If accurate, it places the tug on the New Caledonia station in early 1945 - consistent with the NARA deck-log coverage window (ev-05) and the crew separation record (ev-06).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or adjudicated claim naming USS ATR-27 was found in the public sources searched (see search_ledger).

- Absence of a located public record does not prove absence of asbestos aboard - a 1944 steam plant of this type is era-consistent with asbestos insulation. The hull was scrapped or resold after 1948 with no surviving hull to survey. Does not establish or defeat any individual exposure or eligibility claim.
