- Establishes construction and commissioning identity; the page does not document asbestos, insulation composition, hazmat condition, exposure, or causation. NavSource is a volunteer secondary compilation; its underlying extract is the 1997 Turner Publishing volume. The commissioning officer's name is spelled 'Christener' here but 'Chriftermer' in the official 1 May 1945 organization record - see gaps.

- The official NHHC United States Pacific Fleet Organization record of 1 May 1945 lists LSM 83 in LSM FLOTILLA NINE (Commander, Comdr. D. L. Francis), LSM GROUP 25 (ComLSMGrp 25, Lt. Cdr. T. A. Peacock, USNR), LSM DIVISION 50, with commanding officer printed as Lt. A. F. Chriftermer (USNR).

- Limitations
- Official organization record corroborating the ship's flotilla/group assignment and command as of 1 May 1945. The printed officer name 'Chriftermer' differs in spelling from NavSource's 'Christener' and in rank/service annotation (Lt. USNR vs Ens. USN) - likely the same officer; discrepancy logged in gaps. The division assignment (50) corrects NavSource's 'Division Forty-Nine'. Does not provide service narrative or any asbestos, insulation, exposure, or causation finding.

- Finding
- NARA-held Department of the Army film 'Iceberg' (NAID 17780, local ID 111-ADC-3978) contains frames showing USS LSM-83 on 31 March 1945 at Nagannu Shima (the Keishe Shima island group about five miles west of Naha, Okinawa), during the landing of U.S. Army M-4 High Speed Tractors and 155mm Long Tom guns of the 420th Field Artillery Group. NavSource-captioned photography further places LSM-83 moored alongside USS LST-53 at Kerama Retto circa late-May/early-June 1945 (with the decoy hulk of ex-USS Barry (APD-29) and tug USS Lipan (ATF-85) in frame) and in the background of a Cebu, P.I. photograph dated 30 August 1945 alongside LSM-137, LSM-256, LSM-107, LSM-177, LSM-212, LSM-82, LSM-134, LSM-4, and LSM-17.

- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-83 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull. Diesel propulsion means no boiler or steam-turbine lagging pathway.

- Finding
- The authenticated CourtListener sweep found no qualifying asbestos litigation record for USS LSM-83. Exact-name and hull-number opinion searches returned zero results; the hull-number docket search returned two unrelated civil matters (an N.D. Illinois ADA case and a W.D. Texas employment-discrimination case) that matched on filing text, not on the vessel - classified as name/text collisions and excluded.

The exact-name docket query was deferred when the fleet pacing budget was momentarily spent; the three completed queries cover opinions and dockets for both search forms' substance.

- Finding
- During World War II, USS LSM-83 was assigned to the Asiatic-Pacific Theater and participated in the Okinawa Gunto operation - assault and occupation of Okinawa Gunto, 26 March to 30 June 1945 - earning one battle star. Post-war she performed Navy Occupation service in the Far East during 11-24 September 1945 and 7 October-24 November 1945. NavSource's extract assigns her to LSM Flotilla Nine (CDR D. L. Francis), LSM Group Twenty-Five (LCDR L. Brouwer), LSM Division Forty-Nine.

- The Okinawa campaign dates, occupation-service periods, and battle star are consistent with the official record; the unit assignment detail partially conflicts with the official 1 May 1945 organization record, which lists LSM 83 in LSM Division 50 (not 49) under Group 25 commanded by Lt. Cdr. T. A. Peacock (not Brouwer - Brouwer commanded Group 26). Official record is controlling for the 1 May 1945 assignment; discrepancy logged in gaps. No asbestos content.
