- Finding
- LCI-351 class LCI(L): laid down 26 April 1944 at George Lawley & Sons, Neponset MA; launched 5 May 1944; commissioned USS LCI(L)-683, 12 May 1944. Asiatic-Pacific service: Leyte landings 16 Oct-29 Nov 1944; Nasugbu 31 Jan and 4-5 Feb 1945; Visayan Island landings 26 Mar-9 Apr and 11-14 Apr 1945; Mindanao Island landing 12 Jul 1945; three battle stars. Occupation service 8-25 Sep 1945; China service 26 Sep-16 Dec 1945. Decommissioned and stricken: dates unknown. Transferred to the Maritime Commission 29 December 1947 for disposal; final disposition fate unknown. Photo caption places the craft moored outboard of USS George (DE-697) alongside repair ship USS Briareus (AR-12) at Espiritu Santo, 20 or 21 July 1944, during a seven-day tender availability.

- Limitations
- NavSource is a volunteer-maintained naval-history archive, not an official repository; its history text derives from the Turner Publishing LCI volume. Does not name materials or establish any asbestos content aboard. The Espiritu Santo line is a photo caption from the USS Lunga Point cruise book - a caption-level attribution, and the July 1944 date is tight against the May 1944 East Coast commissioning (transit not otherwise documented). Decommissioning/stricken dates absent.

- Finding
- DANFS records that Quapaw departed Mangarin Bay 26 February 1945 as a unit of Admiral W. M. Fechteler's TG 78.2 en route Puerto Princesa, Palawan, for initial assaults, and that 'enroute Quapaw took LCI-683 in tow when the latter was unable to maintain convoy speed'; the landing forces went ashore 28 February 1945.

Documents one towing event and participation in the Palawan movement; does not address damage, repair outcome, or any material condition aboard.

- The official awards manual credits LCI(L) 683 with these engagement periods: 16 Oct-29 Nov 1944 (code P31-1, Leyte operation); 31 Jan 1945 and 4-5 Feb 1945 (P41-2, Manila Bay-Bicol/Nasugbu); 26 Mar-9 Apr 1945 and 11-14 Apr 1945 (P39-2, Visayan Islands); 12 Jul 1945 (P39-3, Mindanao). Corroborates NavSource's three-battle-star campaign table.

Notably the listing does NOT include a 28 Feb 1945 Palawan period for hull 683 even though DANFS documents her presence in the TG 78.2 Palawan movement - participation credit and physical presence are different facts. No asbestos information.

[5]uboat.net Allied Warships, USS LCI(L)-683 (ship 21748) - build data and transcribed TG 78.2 order of battle / action-report sequence for the Cebu landing (Operation Victor II) [other_primary]

- Finding type
- vessel_history
- Finding
- For the Cebu landing (Operation Victor II, 26 March 1945), LCI(L)-683 sailed in Task Unit 78.2.3, the LCI unit of the TG 78.2 attack force; the operation record notes the LCI wave could not beach on a submerged log-boom obstacle and troops were unloaded just off the beach by LCVP, LCM, and LCT. The order of battle lists Lt.(jg) B.H. Keppel, USNR, as the craft's commanding officer. uboat.net corroborates the NavSource construction data (Lawley/Neponset; laid down 26 Apr, launched 5 May, commissioned 12 May 1944).

- Limitations
- uboat.net is a secondary research site transcribing wartime operation orders/action reports - not an official archive. The same CO name (Keppel) is printed against both LCI(L)-683 and LCI(L)-686 in the transcription, an internal inconsistency: the name is noted here but not asserted as this hull's verified commander (see ev-08 correction row).

[9]Era inference built on: NavSource specification block (two sets of 4 GM 6-71-series diesels, GM reduction gear, twin variable-pitch propellers, two 30 kW diesel-driven generators - no boilers, no steam plant); ONI 226 class data; USS LCI National Association class page (quarter-inch steel-plate hull; quad GM 6-cylinder diesel arrangement); GAO HRD-80-2 for Navy-wide asbestos-use era [other_primary]

- Finding type
- asbestos_application
- Finding
- Era-typical asbestos applications for a 1944 diesel landing craft: engine and exhaust insulation, machinery lagging in the engineroom, flange/engine gaskets, valve packing, and electrical insulation. Built during the Navy's documented asbestos-use era by a yard mass-producing LCIs. No steam plant aboard - so no boiler or turbine lagging pathway exists.

Small diesel landing craft carried far less insulation scope than steam combatants; whether any asbestos product was actually installed aboard hull 683 is unverified. Does not establish quantity, location, or any individual exposure.

- The uboat.net transcription of the TG 78.2 Cebu order of battle lists 'Lt.(jg) B.H. Keppel, USNR' as commanding officer of BOTH LCI(L)-683 and LCI(L)-686 - an internal inconsistency (one officer cannot command two craft); the name is therefore carried as unverified. The hull bore no name (numbered craft; no alias other than short-form 'LCI-683'); the WWII call-sign book confirms radio call sign NPWH, matching NavSource.
