Inc., North Bend, OR; launched 1944-07-12; commissioned USS ATR-86 1944-08-22; assigned to the Asiatic-Pacific Theater during WWII; decommissioned 1946; transferred to the Maritime Commission in 1947 for disposal; struck from the Naval Register, date unknown; final disposition 'fate unknown'; radio call sign NTHK (November-Tango-Hotel-Kilo). Awards listed: American Campaign Medal, Asiatic-Pacific Campaign Medal, World War II Victory Medal, Philippines Liberation Medal (no battle stars listed). Hull-specific spec block: 852 t lt / 1,315 t fl; 165'6" x 33'4" x 15'10"; 12.2 kts trial; 1-3"/50 dual-purpose mount + 2 single 20mm mounts; complement 5 officers / 47 enlisted; largest boom capacity 4 t; propulsion 1 Prescott Co. vertical triple-expansion reciprocating steam engine, 2 Foster Wheeler 'D'-type boilers, 2 turbo-drive ship's-service generators 60 kW 120 V DC, single propeller 1,600 shp.

- Volunteer-compiled transcription of official records plus contributor-supplied photographs; its construction dates corroborate ShipScribe's register compilation, but decommissioned ('1946'), stricken ('date unknown'), and disposal ('fate unknown') entries are less precise than the register's 1946-06-07 / 1946-10-08 / 1947-05-13 values, which this record adopts. The Philippines Liberation Medal listing is the only located indicator of Philippine-area service; no battle star is listed. Boiler vendor (Foster Wheeler) is a NavSource spec-block detail - sister-hull blocks list Babcock & Wilcox; variance logged, not resolved. Contains no asbestos or hazardous-material statement.

- Finding
- An official U.S. Navy photograph credited to 'All Hands' magazine, November 1946 (Bureau of Naval Personnel Information Bulletin, NAVPERS-0 no. 357), shows USS ATR-86 underway with a barge in tow in camouflage measure 31/16Ax - hull number 86 visible on the bow; the photo is displayed via the NavSource ATR-86 page. The November 1946 issue's table of contents (secondary mirror, Gjenvick-Gjonvik Archives) lists a 'Tugs O' War' feature at page 14, consistent context for a towing photograph.

Supports a documentary-photography fact only: the Navy published this hull towing a barge. No asbestos, condition, or materials content.

The index start date matches the commissioning date (1944-08-22), corroborating ShipScribe/NavSource. The listed coverage ends 1945-06-30 - July 1945 through June 1946 logs are not indexed on this list and their location is unverified. Deck logs are operational records - no asbestos content is expected or established by this finding.

- Finding
- Class-level construction documentation for the type this hull belongs to: ShipScribe's class notes state the Navy 'decided to have the vessels built of wood and equipped with relatively simple triple expansion steam machinery' so small shipbuilders and local machine shops could produce them outside the main Navy pipeline; the design is attributed by one source to the firm of John G. Alden; CNO directed construction of ATR 1-40 on 1942-01-19 under the Maximum War Effort (1799-Vessel) Program and VCNO directed ATR 50-89 on 1942-08-05 - the batch containing this hull. The wartime Navy publication transcribed at HyperWar ('US Navy Tugs, 1940-45') describes the class as 'Wooden-hulled Rescue Tugs, built to patrol convoy lanes' with triple-expansion reciprocating steam engines, single screw, 1,600 hp, and lists ATR-86 in commission during 1943-45 (generic list range; actual commissioning 1944-08-22).

The HyperWar '1943-45' column is a generic in-commission range for the list, not a precise commissioning record. No asbestos statement in either source - the fiber content of this hull's boiler/steam-line insulation is not established by any located record.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II, the era and program under which this hull was built (keel laid 1943, commissioned 1944), and that wartime demand drove unprecedented asbestos utilization fleet-wide - including aboard small naval auxiliary hulls built at emergency-program yards such as the one that built this tug.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum/NPS documentation, or litigation naming ATR-86 was found in the public official sources searched. There is no DANFS entry for this hull (NavSource confirms none exists); NARA indexes deck logs (SL-44, 1944-08-22 to 1945-06-30) and RG 19 plan holdings for the hull but contents are unretrieved; MARAD's Vessel History Database indexes six ATR hulls (ATR-9, -68, -70, -78, -79, -81; a seventh row covers MARICOPA ex-ATR-90) but holds no record for ATR-86, consistent with a 1947 Maritime Commission sale leaving no digitized status card; and the Naval Vessel Register categorically excludes vessels disposed before 1987.

- Absence of a located public record does not prove absence of asbestos aboard - a 1944 steam auxiliary is era-consistent with asbestos-containing machinery insulation, and the hull's 1947 sale to a private buyer with unknown subsequent fate leaves no modern survey window. Does not establish that asbestos is or was present or absent; does not establish or defeat any claim of exposure or legal eligibility. Litigation sweep is bounded as described in ev-10.
