- Finding
- NHHC DANFS identifies Hemminger (DE-746) as a Cannon-class destroyer escort: launched 12 September 1943 by Western Pipe & Steel Co., San Francisco; commissioned 30 May 1944; specification block gives displacement 1,240 tons, length 306 feet, beam 36 feet 8 inches, speed 21 knots, complement 186, and Cannon class. The ship trained submarines and conducted patrol and hunter-killer operations in the Pacific, screened a carrier group near Okinawa from 16 May to 20 June 1945, returned to Norfolk in December 1945, decommissioned 17 June 1946, recommissioned 1 December 1950, decommissioned 21 February 1958, and was loaned to Thailand 22 July 1959 as Pin Klao.

- Finding
- The Royal Thai Navy profile identifies HTMS Pin Klao as formerly USS Hemminger (DE-746), built by Western Pipe & Steel in San Pedro, California, with keel laid 8 May 1943 and launched 12 September 1943. It gives normal displacement of 1,240 tons, full-load displacement of 1,900 tons, length 93.27 meters, beam 11.60 meters, and draft 4.54 meters, and describes the armament as three 3-inch/50 guns, three twin 40-mm mounts, two triple torpedo-tube mounts, one antisubmarine rocket launcher, eight depth-charge projectors, and two depth-charge tracks.

- Finding type
- asbestos_application
- Finding
- Class/era inference: Hemminger is a Cannon-class/DET destroyer escort. The DET design used four diesel-generator sets with electric drive, two shafts, approximately 6,000 shaft horsepower, and approximately 21 knots, without propulsion boilers or a steam plant. For a 1943-44 diesel-electric escort, era-relevant asbestos applications are limited to categories such as exhaust insulation, gaskets, packing, electrical insulation, brake linings, and deck coverings; boiler and steam-line lagging cannot be inferred from this propulsion design.

- GAO HRD-80-2 product page; full text not retrieved
- Finding type
- gov_survey
- Finding
- GAO program-level material describes extensive Navy shipboard asbestos insulation use and reports that substitution did not begin until the early 1970s; Hemminger's 1943 construction and U.S. Navy service therefore fall within the documented Navy asbestos-use era.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located for USS Hemminger/DE-746: no hull ACM survey, abatement contract, hazmat disclosure, museum record, or disposal environmental record was found in the sources searched. The authenticated CourtListener sweep returned zero exact-name opinions; the exact-name docket request and hull-number opinion/docket requests were deferred when the required helper reported the fleet-wide pacing budget was momentarily spent.

- Limitations
- A negative search result is not proof that asbestos was absent aboard the hull and does not establish or defeat any exposure claim. CourtListener coverage is incomplete because the fleet limiter required a stand-down; the deferred requests are recorded in the search ledger. Foreign-custody material history after 1959 and final disposition after 2025 are undocumented.
