- Finding
- LSM-84 was laid down 22 August 1944 at Brown Shipbuilding Co., Houston, Texas; launched 15 September 1944; and commissioned as USS LSM-84 on 10 October 1944 with Lt. Robert L. Anderson, USNR, in command. NavSource's commanding-officer list records Lt. Anderson (10 October 1944 - December 1945) followed by Lt.(jg) Francis J. Myers, USNR (December 1945 - 10 May 1946).

- Finding
- After the war USS LSM-84 performed occupation service in the Far East from 7 October to 14 November 1945; was decommissioned 10 May 1946 and laid up in reserve; was loaned to South Korea under the Security Assistance Program on 3 July 1956; was sold outright to South Korea on 5 November 1974 and renamed ROKS Neongna (LSM-659); and was struck from the Naval Register 15 November 1974. Final disposition is listed as 'fate unknown.'

- Limitations
- Establishes postwar chronology and foreign transfer; the page prints 'ROCS Neongna' in this section (header prints 'ROKS') - an internal orthographic inconsistency noted in gaps. Korean-service activity and final disposal are undocumented in U.S. sources; no shipbreaking, hazmat, or asbestos record is supplied for any period.

- Finding
- The official NHHC 'United States Pacific Fleet Organization, 1 May 1945' record lists 'LSM 84 (FF) (1)' in LSM Division 34 (alongside LSM-75, -76, -77, -78, -174), under LSM Group 17 (ComLSMGrp 17, Lt. Cdr. C. H. Johnson, USNR) and LSM Flotilla Six (Commander LSM Flotilla SIX, Comdr. A. R. Quinn). The '(FF)' entry is consistent with flotilla-flagship status; the commanding-officer cell for LSM 84 is blank in the table.

Live NHHC URL returned 404 - archived copy cited; the earlier 2019-11-16 Wayback snapshot is truncated before the LSM Flotillas section, so the 2025-02-14 snapshot (which contains the listing) is cited.

- NARA-held U.S. Coast Guard photograph 26-G-4426 (NAID 205586456, 'Okinawa Beachhead', Records of the U.S. Coast Guard) documents Yellow Beach, Okinawa, 13 April 1945; the NavSource caption identifies USS LSM-84 just visible in the middle distance alongside USS SC-1281, with USS LSM-220, USS LST-1000, and four LCTs working the beach. This places the hull physically present at the Okinawa beachhead during the documented campaign window.

[6]Inference from the ship-specific NavSource diesel specification and the documented source-review negative [other_primary]
- Locator
- NavSource propulsion/specification block; source-review negative documented in search ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-84 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. As a diesel-powered ship she carried no steam plant, so the boiler/turbine lagging pathway of steam vessels does not apply.

- Builder context: the U.S. Naval Institute's Naval History magazine (June 2025) documents that the Brown Shipbuilding Company of Houston, Texas - the yard that built LSM-84 - constructed 254 Landing Ship Medium hulls (alongside 12 submarine chasers, 32 LCIs, and 61 destroyer escorts), employed more than 25,000 workers at its late-1942 onward peak, and was the Houston area's second-largest wartime employer. Brown-built LSMs participated in nearly every major Pacific amphibious operation including Okinawa.

- No ship-specific asbestos documentation was located in the public sources reviewed: the live NavSource hull page, the official NHHC 1 May 1945 fleet organization record, the NARA catalog item, the NVR resource, and the authenticated CourtListener results contain no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or qualifying asbestos litigation record for LSM-84.

- During World War II, USS LSM-84 was assigned to the Asiatic-Pacific Theater as flagship of LSM Flotilla Six (Comdr. A. R. Quinn, USN) and flagship of LSM Group Seventeen (Lt. Cdr. C. H. Johnson, USNR), in LSM Division Thirty-Four; she participated in the assault and occupation of Okinawa Gunto, 1 April to 17 June 1945. Photographs on the hull page place her beached at Guadalcanal (date unknown) and at Yellow Beach, Okinawa, 3 and 13 April 1945. She earned one battle star for World War II service.
