- Finding
- NavSource's ATR-14 vessel page records: laid down 7 October 1942 at Delaware Bay Shipbuilding Co.; launched 13 November 1943; delivered 29 April 1944; commissioned USS ATR-14, 29 April 1944; decommissioned 'date unknown'; struck from the Naval Register in 1946; 'Final Disposition, fate unknown.' Awards block: American Campaign Medal and World War II Victory Medal - no battle stars, no theater ribbons. Call sign NHAP. A contributor-supplied photograph shows the tug underway probably on builder's trials near the builder's yard at Leesburg, N.J., circa April 1944. Specifications listed: displacement 852 t. light / 1,315 t. full; 165'6" x 33'4" x 15'6"; 12.2 kts; one 3"/50 dual-purpose mount, two single 20mm AA mounts; 4-ton boom; complement 5 officers, 47 enlisted; fuel 1,620 bbls NSFO; one Fulton Iron Works vertical triple-expansion reciprocating steam engine, two Foster Wheeler 'D'-type boilers (200 psi, saturated), two 60 kW 120V DC turbo-drive ship's-service generators, single propeller, 1,600 hp. Page states no DANFS history is available for ATR-14.

- Shipscribe's ATR-1-class compilation (Stephen S. Roberts, drawing on Navy directives, Navy register data, and Maritime Commission records) documents for ATR-14: ordered 22 June 1942, builder Delaware Bay SB; keel 7 October 1942; launched 13 November 1943; commissioned 29 April 1944. Disposition table: decommissioned 26 August 1946; stricken 8 October 1946; disposal 12 May 1947 coded 'MC/D' (Maritime Commission disposal); MA sale 12 May 1947. Ship note: 'Sold (delivered) by MC to James J. Schwebel, New York.' Class header data: design Navy ATR-1; 852 t light / 1,315 t max; 165.4' oa x 33.3' x 15.8' max; complement 51 (1944); 12.2 kts; 1,600 HP; 1 screw, vertical triple expansion; armament 1-3"/50, 2-20mm. Class notes record the 12 September 1941 BuShips letter proposing rescue-tug requirements, CNO's 19 January 1942 direction of ATR 1-40 under the Maximum War Effort (1799-vessel) program, VCNO's 5 August 1942 direction of ATR 50-89, the selection of wood construction and triple-expansion machinery to route work to small yards and machine shops, and design attribution to the John G. Alden firm per one source.

- Finding
- The Delaware Bay Shipbuilding yard production table lists ATR-14: owner US Navy, type Tug, 850 LDT, 156 ft, delivery entry '29-Apr-45,' disposition 'Disposed of 1946.' Yard background on the same table: Delaware Bay Shipbuilding Co., Inc. formed 1920 by Dr. Malcolm Sharp; bought 1929 by investors and split with Debasco Boat Works; yard stood on Main Street at Sharpstow Lane, Leesburg NJ (site of today's Yank Marine repair yard); wartime production included AMc minesweepers, SC sub chasers, and rescue tugs ATR-13, ATR-14, ATR-58, ATR-59.

- Limitations
- Independent secondary compilation of yard records; corroborates builder, yard location, type, and disposal year, but its '29-Apr-45' delivery year conflicts with the 1944 delivery/commissioning corroborated by NavSource, Shipscribe, and the NARA deck-log coverage start (1944-04-29) - treated as a typo and logged in gaps; 1944 adopted. The same table's '23-Dec-44' delivery for ATR-13 likewise conflicts with Shipscribe's 23-Dec-43 commissioning, suggesting a table-wide +1-year defect on the Delaware Bay rows. No asbestos or material information.

- Finding type
- 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 Foster Wheeler '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.

Does not establish quantity, locations, present-day presence, individual exposure, or causation.

- NARA holds two classes of hull-specific records for ATR-14. (a) Special List 44 (NARA's WWII deck-log index by hull number) inventories ATR-14 deck logs covering 1944-04-29 (commissioning) through 1945-06-30 - the deck-log start date independently corroborates the 29 April 1944 delivery/commissioning date. (b) The NARA Ship Plan Index (Cartographic Branch) lists two RG 19 (Bureau of Ships) entries for hull ATR-14: 'Portfolio Plans' NAID 175661889 and 'Microfilm' NAID 175668233.

- historical_record
- Finding
- NARA describes asbestos use in U.S. Navy materiel from 1941 through 1961 as a frequently requested topic requiring ship-by-ship archival research in Bureau of Ships RG 19 records (general/confidential correspondence 1940-1946 arranged by Navy Filing Manual; hull-designation files; shipyard 'QM' contractor files; S39 insulation-and-lagging and S48 piping drawings in the Cartographic Branch). ATR-14 was built 1942-44 within that era, but the guide identifies no material aboard this hull. For this vessel the applicable filing paths are the ATR-14 hull file, the ATR-1 class file, and the QM contractor files for Delaware Bay Shipbuilding; the hull's indexed plan sets (NAIDs 175661889, 175668233) are a concrete starting point.

No qualifying asbestos litigation naming this vessel was located in these indexes.
