- NavSource is a volunteer secondary compilation, not a primary registry - the history extract is credited to Turner Publishing's LSM-LSMR Amphibious Forces Vol. II (1997). Milestone dates generally track official lists but are not independently verified against a primary registry; where conflicts exist they are carried in gaps. Campaign-credit label 'Iwo Jima operation' is internally inconsistent with its own 'Okinawa Gunto' description and dates (see correction row ev-10). Contains no asbestos content.

- Primary wartime record naming this hull. The group commander's action/operation report states: 'During the period 16 April 1945 to 17 June 1945, LSM Group SEVENTEEN worked as lighterage, smoke ships, and towing ships under CTU 51.22.6 (Commander Quinn, ComLSMFlotSIX) in vicinity Hagushi Beach Area of Okinawa, Ryukus Islands' and 'The reporting command consisted of Commander, LSM Group SEVENTEEN (Lt.-Comdr., C.H. Johnson, Jr.) in LSM 72, and LSMs 71, 73, 76, 77, 78, 80, 174 and 222, a part of Task Unit 51.22.6.' The report records round-the-clock unloading of transports/merchant ships at Okinawa under nightly air alerts, and group-level findings (fuel-tank ruptures in LSMs 72 and 277; prolonged beaching damage; air-attack conditions).

- asbestos_application
- Finding
- A diesel-powered amphibious landing ship built July-September 1944 at a wartime emergency yard sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel vessel of this type and period were thermal insulation in machinery spaces, diesel-exhaust lagging, gaskets, valve and flange packing, and electrical insulation. She carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

LSMs were austere amphibious auxiliaries with far less insulated steam-type piping than combatants; the extent of any asbestos aboard is not documented.

CourtListener: 'USS LSM-71' returned zero opinions and zero dockets; bare 'LSM-71' opinions returned 39 hits, all token-level name collisions (the literal string 'LSM-71' appears in no returned snippet - matches are unrelated contract/docket text); bare 'LSM-71' docket search was blocked by the fleet pacer and is logged as pending, not a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard' material is law-firm marketing content - excluded by source policy.

- Finding
- CORRECTION: NavSource's campaign table labels this hull's battle-star campaign 'Iwo Jima operation' while describing it as 'Assault and occupation of Okinawa Gunto, 8 to 26 April 1945' - the label is internally inconsistent with its own description and dates. The primary records resolve the conflict toward Okinawa: the group war diary places LSM-71 at Hagushi Anchorage, Okinawa, 9-25 April 1945 (unloading transports, lighterage/smoke duty), and the group action report covers the Okinawa area 17 April-17 June 1945. The Iwo Jima assault itself ran 19 February-16 March 1945; the group's war diary shows LSM-71 still at Espiritu Santo on 1-3 April, transiting to Okinawa - her credited service was the Okinawa operation, not the Iwo Jima assault.
