- Official BuShips register lists ATR-9 individually: built by Frank L. Sample, Jr., Boothbay Harbor, Maine; keel laid 18 Aug 1943; launched 20 May 1944; first commissioned 3 Aug 1944; engine manufacturer Fulton Iron Works, vertical triple-expansion; boiler manufacturer Foster Wheeler, type 'D' (per-hull ditto chain from the explicit F.W. 'D' row for ATR-7). Class block for ATR 1-40 rescue tugs: wood hulls; 165 ft 5 in overall, 155 ft waterline, 33 ft 4 in beam; 12.2 kt trial speed; trial displacement 1,312 tons (limiting 1,315 t, limiting draft 15 ft 10 in); single screw, 1,600 shp, 2 boilers at 260 psi saturated steam; accommodations 5 officers + 47 enlisted; armament one 3"/50 cal (D.P.); largest boom capacity 4 tons; fuel oil 1,620 bbls; two 60 kW 120 V D.C. turbo-driven ship's-service generators; no main reduction gears.

- Establishes identity, construction dates, builder, and this hull's propulsion plant (named manufacturers) as of the April 1945 publication. The Foster Wheeler boiler attribution rests on a printed ditto chain (explicit 'F.W. D' at ATR-7, 'do' at ATR-8/9) - table ditto conventions are unambiguous but the per-hull entry is one step removed from the explicit row. Contains no asbestos or insulation-material statement; the documented steam plant supports - but does not prove - the era-level asbestos inference. Does not address wartime modifications or post-service materials.

The DANFS Van Valkenburgh entry independently records 'ATR-9 soon arrived on the scene and towed the crippled destroyer to Kerama Retto.'

- Finding
- Era/design inference for a wooden-hulled steam rescue tug of 1943-44 construction: this class carried two 'D'-type boilers (Foster Wheeler per this hull's SDB1945 row) at 260 psi saturated plus a vertical triple-expansion engine, so the boiler-lagging pathway applies - era-typical applications are boiler and steam-drum insulation, steam-line lagging, exhaust-uptake insulation, valve and flange gaskets, machinery packing, engine-room thermal/acoustic insulation, accommodation insulation, and brake linings on towing machinery and windlass. The wooden hull narrows structural insulation scope but does not eliminate machinery insulation. Peer-reviewed scholarship documents extensive asbestos use in WWII U.S. shipbuilding generally during this hull's construction era.

- Disposition-date correction: NavSource records ATR-9 'decommissioned, date unknown,' 'struck from the Naval Register in 1946,' and 'disposed of in 1946, fate unknown.' The shipscribe compilation of Navy/MC disposal records gives the fuller chain - decommissioned 5 Nov 1946, stricken 28 Jan 1947, sold through the Navy Surplus Property Office, Honolulu, probably for UNRRA use in China. The shipscribe dates are adopted: they derive from the disposal record series and are consistent with the hull's documented presence at Okinawa through at least Nov 1945 (typhoon damage) and a postwar Pacific disposal channel.

- Finding
- Program context: the Navy deliberately procured the ATR-1 class as wooden-hulled tugs with simple triple-expansion steam machinery so that small shipbuilders not engaged in the main Navy steel-ship effort could build the hulls and small local machine shops could build the engines; one source attributes the design to the John G. Alden firm. BuShips had argued (1941-09-12 letter to CNO) that rescue tugs needed good seaworthiness, >=1,500 HP to tow large vessels, a towing engine, long radius of action, firefighting equipment, and a basic supply of salvage materials and pumps. ATR 1-40 were directed by CNO 1942-01-19 under the Maximum War Effort (1799-Vessel) Program; ATR 50-89 added by VCNO 1942-08-05 (FY1943).
