- Finding
- Contemporaneous primary reporting of the Featherston POW repatriation embarkation: on the morning of 30 December 1945 two trains ran Featherston-to-Wellington (Aotea Quay) discharging New Zealand's ~800 Japanese prisoners of war into two waiting American LSTs, which sailed by 1 p.m.; Captain A. Ashton commanded the New Zealand guard escort; the ~5,600-mile voyage to Japan was expected to take ~30 days with water stops in the Solomons and Marianas (NZ Herald). The Evening Post identifies the first train's receiving ship as 'the flagship of the LSTs' under Lieut.-Commander Robert P. Rudolph - the documented commanding officer of LST-275 (NavSource CO table: Rudolph 14 Jul 1945-March 1946) - carrying the 'fighting men,' while 'the other vessel' took the laborers.

- Limitations
- The NZ press never prints hull numbers: the LST-275 identification rests on triangulation - Evening Post names Rudolph's flagship; NavSource documents Rudolph commanding this hull through March 1946. The LST-273/LST-275 pairing and the 4 February 1946 Uraga disembarkation date rest on secondary compilations (Wikipedia Featherston article citing NavSource's LST-273 veteran memoir and an LST-275 sailor's private diary) - not asserted here as primary fact. DANFS 'occupation duty in the Far East until mid-February 1946' and NavSource 'occupation service 1-26 February 1946' frame the mission window without naming it. No asbestos content.

- asbestos_application
- Finding
- A diesel-powered LST-1-class tank landing ship built 1943 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel amphib of this type and period were engine exhaust lagging, engine-room thermal/acoustic insulation, gaskets and valve packing, deck coverings/tile, accommodation insulation, and winch/crane brake linings. The diesel plant removes the boiler/steam-line lagging pathway of steam vessels; exposure relevance concentrates in machinery spaces, interior insulation, and the documented yard periods - above all the August-September 1945 Hunter's Point availability with repair barges YR-39/YR-44, plus the October 1943 fitting-out at New Orleans naval facilities - whose material scope is unrecorded.
