- Finding
- Shipscribe (Stephen S. Roberts) compilation of Navy construction/disposition records for the ATR-1 class: construction table lists ATR-58 ordered 27 Nov 42, builder 'Delaware Bay SB' (Delaware Bay Shipbuilding Co., Leesburg NJ), keel 18 Aug 43, launch 23 Apr 44, commissioned 11 Aug 44. Disposition table lists decommissioned 25 Apr 46, struck 8 May 46, disposal 7 Jul 48 to Maritime Commission custody (fate code MC/D), MA sale 18 May 48. Ship note: 'Sold (awarded) by MC to Duelin Steel Products Co., Seattle, Wash.' Class notes: the Navy deliberately specified wooden hulls and simple triple-expansion steam machinery so small shipbuilders and local machine shops could produce the tugs outside the main war-shipbuilding program; the design is attributed in one source to the firm of John G. Alden; ATR 1-40 were directed by CNO 19 Jan 42 and ATR 50-89 by VCNO 5 Aug 42 under the Maximum War Effort (1799 Vessel) Program; the 80 wooden ATRs averaged 9.4 months keel-to-launch and 13.6 months keel-to-commissioning.

- NavSource Online Service Ship Photo Archive entry for ATR-58: 'Laid down, 18 August 1943, at Delaware Bay Shipbuilding, Leesburg, N.J. Launched, 23 April 1944. Commissioned USS ATR-58, 11 August 1944, LT. G. B. Barry in command. During World War II USS ATR-58 was assigned to the Asiatic-Pacific Theater. Following World War II USS ATR-58 was assigned to Occupation Service in the Far East from 2 September to 27 November 1945. Decommissioned, date unknown. Struck from the Naval Register, date unknown. Final Disposition, disposed of in 1946, fate unknown.' Awards line: American Campaign Medal, Asiatic-Pacific Campaign Medal, WWII Victory Medal, Navy Occupation Service Medal (Asia clasp). Spec block: 852 t. light / 1,315 t. full; 165'6" x 33'4" x 15'6"; 12 kts; one 3"/50 DP + two single 20mm AA; complement 5 officers + 47 enlisted; NSFO 1,620 Bbls; one Prescott Co. triple-expansion reciprocating steam engine, two Foster Wheeler 'D'-type boilers 200psi sat., two turbo-drive 60kW 120V DC ship's-service generators, single propeller 1,600 shp. Photo (094005801) shows the tug underway probably at Philadelphia prior to commissioning (National Association of Fleet Tug Sailors, courtesy Walter Zuhn).

The Naval Cover Museum wiki separately prints 'Transferred to War Shipping Administration June 7 1948' - a one-month conflict with the Shipscribe MC-custody date. The Shipscribe dates are carried in this record; the WSA-vs-MC attribution and the June-vs-July date are logged in gaps.

- Resolves NavSource's 'date unknown / fate unknown' against Shipscribe's compiled Navy/MC record (decomm. 25 Apr 46, strike 8 May 46, MC custody 7 Jul 48, sale 18 May 48). The NavalCoverMuseum 'WSA, June 7 1948' variant is unresolved - WSA's residual ship-disposal functions had passed to the Maritime Commission by 1948, so 'WSA' is likely loose attribution, but no primary custody document was located. No asbestos content.

- Finding type
- vessel_history
- Finding
- The ATR type's intended employment is described in a June 1944 COMINCH publication prepared in the Bureau of Ships from notes submitted by Commodore W. A. Sullivan, Chief of Navy Salvage: 'ATRs are new wooden tugs originally designed to render emergency assistance to vessels disabled on the high seas in enemy submarine infested coastal waters of the United States. They are extremely well fitted for firefighting and have moderate salvage facilities. ATRs have excellent seagoing qualities and good towing power but are sharply limited in endurance and radius of action.'

- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this wooden-hulled tug was built at Delaware Bay Shipbuilding, Leesburg NJ, in 1943-44. The documented steam plant (two Foster Wheeler 'D'-type boilers at 200 psi and a Prescott triple-expansion engine, with associated steam piping and two turbo-drive generators) carries the boiler-room and steam-line lagging application class that dominates steam-ship exposure profiles; plausible era applications include boiler and steam-drum insulation, steam-line lagging, valve and flange gaskets, machinery packing, and electrical/bulkhead insulation.

- WWII shipyard workers and ship crews (class context); Delaware Bay Shipbuilding trades 1943-44; ATR-58 engine-room crew
- Limitations
- Program/era-level scholarly documentation of asbestos use in WWII shipbuilding generally; does not name this vessel or class and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. The steam plant places this hull in the higher-insulation-load category relative to diesel-electric tugs, but the wooden hull and the tug's small size bound plausible scope. No surveyable structure is known to exist - the hull was sold to a private buyer in 1948 and its fate is unrecorded.

- Finding
- Archival leads (not retrieved - require research-room or reproduction order; no spend authorized): NARA's asbestos research guide points to Bureau of Ships RG 19 general correspondence and ship/class/type files - the ship-by-ship path for Navy asbestos questions; for this hull the ship file would be under designation 'ATR58' and the builder under the private-contractor code 'QM/Delaware Bay Shipbuilding.' NARA also holds deck logs for ATR-58 covering 11 Aug 1944 - 30 Jun 1945 (SL-44 ship-number index), independently corroborating the commissioning date. Maritime Commission disposal records for the 1948 sale may survive in MC/WCC records at NARA - the MARAD Vessel History Database holds no status card for ATR-58 (keyword search 'ATR-58' returned no vessel; sibling ATRs 9, 68, 70, 78, 79, 81 do have entries, confirming the index covers the type).

The NARA guide identifies possible record series, not a located ATR-58 file or any asbestos finding. The SL-44 hit confirms deck logs exist and corroborates the commissioning date, but the logs were not retrieved. Nothing in this row is an asbestos finding.

- No qualifying asbestos litigation - indeed no litigation of any kind - located naming this hull in the searched indexes. 'No qualifying litigation found' is a finding about the searched indexes, not proof no suit was ever filed: unindexed or non-public complaints cannot be ruled out. The number-only designation has no collision surface - no name variants exist - so the zero-hit sweep is complete for identity.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, environmental filing, court finding, or docketed case naming ATR-58 / USS ATR-58 was found in the public sources searched (see search_ledger). No individual DANFS entry exists for the hull (unnamed auxiliary). The hull was sold by the Maritime Commission in 1948 to a private buyer and its fate is unrecorded - no extant structure is known to survive, so no later abatement or donation record can arise.

- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44-built steam-driven hull is era-consistent with asbestos-containing boiler and machinery insulation. The hull was disposed of to private hands in 1948 and is not known to survive. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
