Burdick, USNR, in command (sole listed CO, 24 April 1944 - 11 January 1946). Campaign table: Western Caroline Islands operation, capture and occupation of southern Palau Islands, 6 September to 14 October 1944; LST-607 transported LCT-782 to the Western Caroline Islands.

Occupation service: 15 September - 2 November 1945 and 23 November 1945 - 11 January 1946. Decommissioned 11 January 1946 and assigned to COMNAVFE Shipping Control Authority for Japan (SCAJAP), redesignated Q008. Transferred to MSTS 31 March 1952, in service as USNS T-LST-607. 'Placed out of service and struck from the Naval Register, date unknown.' Transferred to the Republic of the Philippines 13 September 1976, named BRP Leyte del Sur (LT-505); photographed in Philippine service at Cavite, Luzon, July 1988; 'Final Disposition, fate unknown.' Ribbons displayed: American Campaign Medal; Asiatic-Pacific Campaign Medal (1); WWII Victory Medal; Navy Occupation Medal (Asia clasp).

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates generally track NVR/DANFS, and its dates agree with DANFS and the BuShips roster for this hull. Contains no asbestos or material-composition content. The stricken date is expressly 'unknown' on this page - a 1 November 1973 date circulates in secondary compilations but is unverified (see gaps). 'Fate unknown' after the 1988 Cavite photograph means the hull's final disposition is undocumented, not that it survives.

- Finding
- The official BuShips roster lists LST-607 under the 'Chicago B. & I. Co., Seneca, Ill.' builder block: keel laid 2 December 1943, launched 7 April 1944, date of first commission 24 April 1944 - matching DANFS exactly. The LST design table for the LST542-931 group (which contains this hull) gives 328 ft overall, 50 ft beam, 2,366-ton light and 4,080-ton trial displacements, 11.6-knot trial speed, and machinery of 2 G.M. Diesel 12-567A engines at 1,700 shp; accommodations rows for the group list 13 officers and 106 enlisted.

- Yard context and build-table corroboration: the Navy requisitioned the Chicago Bridge facility in Seneca, IL, in 1942 and invested $6 million in its improvement; known as the 'Prairie Shipyard,' it occupied a 200-acre site on the east side of town and was sold to Union Mechling in 1949. The yard's hull table lists LST 607 - U.S. Navy Landing Ship, Tank - laid 12/2/43, launched 4/7/44, delivered 4/24/44 (127 days on the ways, 17 days fitting out, 144 total), disposition 'To the Philippines 1976 as Leyte del Sur (LT 505)' - agreeing with DANFS and the BuShips roster.

- Finding type
- asbestos_application
- Finding
- Class/era inference: the LST542-931 design group used diesel propulsion - no boilers - so the boiler/steam-lagging pathway of steam vessels does not apply. For a 1944 diesel LST, era-standard asbestos-relevant applications may have included diesel-exhaust lagging, machinery gaskets and packing, engine-room thermal or acoustic insulation, deck coverings or tile, accommodation insulation, and winch or windlass brake linings, within the confined below-decks volume of a 328-foot hull. No source located for this record confirms that any listed application was installed aboard LST-607.

- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s; its 1975 policy removed and replaced nonasbestos materials only when insulation was damaged or had to be removed for necessary repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas - program-level context spanning this hull's U.S. construction and service era (1943-1976).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, insulation drawing, material schedule, or verified litigation naming USS LST-607 / USNS T-LST-607 / BRP Leyte del Sur was found in the public sources searched. CourtListener authenticated-API searches returned count 0 for opinions ('LST-607', 'USS LST-607', 'LST 607') and dockets ('LST-607', 'USS LST-607'); one Philippine-name variant query ('Leyte del Sur') remained pending on the fleet pacing limiter. Secondary web sweeps surfaced only law-firm marketing content asserting asbestos without primary sourcing (including one page asserting boiler-room asbestos on the diesel-powered LST-542 class - a technical error).
