- NavSource service record for USS ATR-63: commissioned with LT. R. W. Coffey in command; during WWII assigned to the Asiatic-Pacific Theater, Service Squadron Two; displayed awards American Campaign Medal, Asiatic-Pacific Campaign Medal, World War II Victory Medal; struck from the Naval Register 1946-04-17; '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 Fulton Iron Works vertical triple-expansion engine; two Babcock & Wilcox 'D'-type boilers, 200 psi saturated; two 60 kW turbo-driven ship's service generators; single propeller 1,600 shp; armament 1x3"/50 DP, 2x20mm; complement 5 officers + 47 enlisted; fuel 1,620 bbls NSFO.

- Limitations
- Volunteer-compiled archive; the page's laid-down/launch/commissioning dates are ATR-62's register dates and are corrected at ev-03 - the dates in the narrative are NOT adopted, while the assignment, CO, awards, and spec block are retained as stated. Spec block is class-level data restated on the hull page. 'Disposed of 1946' conflicts with the register's 1948 MC transfer - register controls. No asbestos information; supports no asbestos claim.

- Finding
- Construction-date discrepancy resolved: NavSource's ATR-63 page states laid down 1943-05-14, launched 1944-05-30, commissioned 1944-07-14 - these match the register row for sister ATR-62 verbatim (keel 14 May 43 / launch 30 May 44 / comm 14 Jul 44), a misattribution. The register data for ATR-63 (keel 1943-11-06, launch 1944-07-11, commissioned 1944-08-16) is corroborated by NavalCoverMuseum's ATR-63 entry and by NARA Special List #44, which lists this hull's deck logs beginning 1944-08-16.

- Finding
- NARA Special List #44 (deck-log inventory by ship number) lists USS ATR-63 deck logs covering 1944-08-16 through 1945-06-30 - the period from commissioning through nearly the end of WWII. Logs are paper custody, not digitized; no coverage for 1945-07-01 through 1946-03-27 (decommissioning) appears in the list.

Custody start date independently corroborates the 1944-08-16 commissioning (ev-03). Post-June-1945 logs are not in this list - location unknown. Contains no asbestos information.

- Finding type
- vessel_history
- Finding
- ATR-1 class design/procurement context: BuShips' 1941-09-12 letter to CNO argued the need for rescue tugs to tow disabled vessels; CNO directed ATR 1-40 construction 1942-01-19 under the Maximum War Effort (1799-Vessel) Program and VCNO directed ATR 50-89 on 1942-08-05. To avoid competing with steel combatant construction the Navy built the type with wooden hulls and simple triple-expansion steam machinery, letting small shipyards and local machine shops do the work; one source attributes the design to the John G. Alden firm. Class service pattern: NHHC's DANFS entry for Narraguagas (AOG-32) places sister rescue tugs ATR-38 and ATR-62 in towing unit TU 30.9.23 in the Okinawa operation, June 1945 - the employment context for ATR-63's documented Asiatic-Pacific assignment.

The Alden design attribution is hedged by the source itself ('one source indicates'). The Okinawa citation names ATR-38 and ATR-62, not ATR-63. No asbestos content; supports no asbestos claim.

[7]Corn, Jacqueline Karnell, and Jennifer Starr, 'Historical perspective on asbestos: Policies and protective measures in World War II shipbuilding,' American Journal of Industrial Medicine 11(3):359-373 (1987); applied to the NavSource-documented plant configuration [other_primary]

- Finding type
- asbestos_application
- Finding
- Era-level documentation: asbestos was used extensively as insulating and fireproofing material in U.S. WWII shipbuilding. Applied to this hull only as inference: a 1944-vintage steam plant (two Babcock & Wilcox 'D'-type boilers, Fulton vertical triple-expansion engine, single screw) is consistent with period asbestos applications - boiler insulation, steam-line lagging, flange/valve gaskets, machinery packing, brake linings on towing and anchor machinery, and accommodation-space insulation. The class's wooden hull removes the structural-steel fireproofing a steel ship would carry.

PACER was not searched (no spend authorized). A hull-specific absence is consistent with a small, short-lived, unnamed auxiliary disposed in 1948.

The hull left federal custody in 1948 and carries no NRHP/NHL/museum status that would generate modern condition documentation; no post-sale identity is documented.
