- Finding

- Limitations
- Establishes decommissioning and reported sale; secondary sources conflict on the sale year (1949) and give a strike date (3 July 1946) not verified against an official record - both carried in gaps. No shipbreaking, hazmat, or asbestos record is supplied.

- Archived copy (2024-01-18 capture), LSM Flotilla Six / LSM Group 17 / LSM Division 34 table; live NHHC URL returned 404 and the 2019-11-16 capture truncates before the LSM sections

- vessel_history
- Finding
- The official NHHC 1 May 1945 Pacific Fleet organization record lists LSM 77 in LSM Division 34 under LSM Group 17 (ComLSMGrp 17, Lt. Cdr. C. H. Johnson, USNR) of LSM Flotilla Six (Comdr. A. R. Quinn); no commanding-officer name is recorded for LSM 77 in the table.

- Limitations
- Official contemporaneous organization record. It corroborates the flotilla and group but places the ship in Division 34, conflicting with the hull page's 'Division Thirty-Three' - reported as a documented discrepancy rather than resolved. Does not provide the full service history or any asbestos, insulation, exposure, or causation finding.

- Finding
- The hull page lists 5 officers and 54 enlisted, troop accommodations for 2 officers and 46 enlisted, and two Fairbanks Morse model 38D81/8X10 reversible diesel engines with hydraulic clutches, direct drive, 1,440 BHP each at 720 rpm, twin propellers, and 2,800 shp; it also lists two diesel-drive 100-kW 450-V AC generators and one diesel-drive 20-kW 120-V DC generator. The propulsion is all-diesel - no boilers or steam plant.

- Finding
- The Navy's wartime transport doctrine publication describes the Landing Ship, Medium as originally designated LCT(7), developed as an ocean-going tank lighter combining the bow gates of the LST, the well deck of the LCT(6), and the conning tower of the LCI; the HyperWar 'Ships of the U.S. Navy, 1940-1945' LSM class block lists the class propulsion as Fairbanks-Morse diesel or GM Cleveland diesel direct drive, 2,800 hp.

- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-77 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.

- The authenticated CourtListener sweep found no qualifying asbestos litigation record for USS LSM-77: the exact-name opinion query ("USS LSM-77"), the hull-number opinion query ("LSM-77"), and the hull-number docket query ("LSM-77") each returned zero results.

- Finding type

- Finding
- No ship-specific asbestos documentation was located in the public sources reviewed: the live NavSource hull page, official NHHC organization record, DANFS (no entry exists), and authenticated CourtListener results contain no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or qualifying asbestos litigation record for LSM-77.

- A negative public-source finding is not proof that asbestos was absent. Non-digitized Navy, shipyard, and scrapping records may contain additional evidence; asbestos documentation therefore remains class_or_era.

- Finding type
- vessel_history
- Finding
- During World War II, USS LSM-77 was assigned to the Asiatic-Pacific Theater under LSM Flotilla Six (CDR A. R. Quinn, USN), LSM Group Seventeen (LCDR C. H. Johnson, USNR), and LSM Division Thirty-Three, and participated in the Okinawa Gunto operation (assault and occupation of Okinawa Gunto, 9 April to 30 June 1945). The ship earned one battle star for World War II service. The page's post-war paragraph is headed 'USS LSM-76' (an evident numbering slip on the LSM-77 page) and lists Navy Occupation Service Medal and China Service Medal (extended) service for 3 September to 30 November 1945, matching the awards rack shown for LSM-77.
