- DANFS record for this hull (Grapple I, ARS-7): launched by Basalt Rock Co., Napa, Calif., 31 December 1942; sponsored by Mrs. Thomas D. Rose; commissioned 16 December 1943 at Vallejo, Calif., Lt. Robert Fisher in command. Specs: dp. 1,897; l. 213'6"; b. 39'; dr. 14'1"; s. 14.8 k.; cpl. 120; a. 4 40mm; cl. Diver. WWII combat salvage: Guam assault support from 21 July 1944 (landing craft recovery, ship repair under fire, Apra Harbor demolition clearance); Peleliu mooring buoys and two-plus weeks repairing mined USS Wadleigh (DD-689); salvage of smoldering Liberty ship SS William Sharon in Mindanao Gulf under air attack late December 1944; Lingayen Gulf salvage 6 January-26 February 1945 earning the Navy Unit Citation; firefighting on kamikaze-hit USS Randolph (CV-15) 11 March 1945. Decommissioned San Diego 30 August 1946. Recommissioned 26 December 1951 per DANFS; Korea 1952 flycatcher patrols - shore-battery hit 12 August (6x15-inch hole, projectile removed by damage control), USS Chief (AM-315) friendly fire 15 August (2 killed, 11 injured, 3 critically); Seattle overhaul. Pearl Harbor based; Arctic supply cruises 1953, 1955, 1956, 1957; Johnston Island reef blasting April 1954; Quemoy-Matsu standby August-September 1958; Hilo tsunami assistance May 1960; Frank Knox (DDR-742) salvage participation dated '1964' by DANFS (corrected to July-August 1965 by the official SUPSALV report, ev-03); South Vietnam from 10 December 1966. DANFS narrative ends with ship on station in the Pacific (entry text vintage c. 1968); DANFS closing line credits 'one battle star for World War II service and one for Korean service' - conflicts with the itemized NavSource campaign record (see gaps).

Docket searches: bare 'Grapple' (type=r) -> 21,908 dockets, unusable free-text noise (the verb appears throughout docket-entry text); '"USS Grapple"' (type=r) -> 3 dockets whose indexed content contains the exact phrase: Hickman v. CBS Corporation (D. Del., asbestos personal-injury nature-of-suit), Bell v. Foster Wheeler Energy Corporation (E.D. La. 2:15-cv-06394, asbestos personal-injury nature-of-suit), and the JPML MDL-875 master docket 'In re: Asbestos Products Liability Litigation (No. VI)' that aggregates such matters. The point of occurrence of the phrase within those docket corpora is not inspectable through the search interface; presence of a ship name in asbestos PI docket text is consistent with pleading-stage ship/service-list exhibits, which are allegations, not adjudicated findings. No published opinion naming this hull was located. Classification: no qualifying asbestos litigation at any adjudicated stage; pleading-stage name traces only, described exactly.

- Litigation-stage discipline applied: the only CourtListener occurrences of this vessel's name are inside asbestos PI docket corpora (Hickman, Bell, MDL-875 master) - pleading/discovery-stage allegations at most, NOT findings; no opinion names the hull, so no adjudicated-stage exposure record exists. Coverage is partial, not exhaustive: a Taiwan-name opinion query ('Da Hu' asbestos) was blocked by the fleet-wide pacing limiter and uncompleted; bare 'Grapple' docket review is inherently unbounded (21,908 hits) and was assessed by top-relevance ranking only. Does not establish that no filing anywhere names the hull.

- Class/design context: Grapple is a Diver-class rescue and salvage ship built to the Navy ARS-5 design (ShipScribe class page): 213.5 ft oa, ~1,940 lim. tons, diesel-electric twin screws at 3,000 hp. The diesel-electric plant has no boilers and no steam propulsion system, narrowing the principal steam-lagging pathway documented for steam-driven WWII hulls. Era-typical residual applications plausible aboard this type - diesel exhaust/muffler lagging, machinery gaskets and packing, electrical cable insulation, accommodation-space insulation, and brake linings on salvage winches/deck machinery - are not documented for this hull by any source located.
