- Official U.S. Navy loss record: under 'SUPPORT LANDING CRAFT' the CNO's report lists 'LCS 49 - Off Luzon, P.I. - 16 February 1945'. This is the official wartime record that this hull was lost by enemy action off Luzon on 16 February 1945. The same table lists LCS 7 (Off Luzon, 16 February 1945), LCS 26 (Off Luzon, 16 February 1945), LCS 15 (22 April 1945), LCS 33 (Off Okinawa, 12 April 1945), and LCS 127 (Off California, 5 March 1945).

- Association history for this hull: commissioned 31 August 1944 at Albina Engine and Machine Works, Portland, Oregon; assigned to Flotilla One, Seventh Fleet, Task Unit 78.3.8 (LCSs 7, 8, 26, 27, 48 and 49). Gunnery crew trained at Little Creek, Virginia; remainder of crew at Amphibious Base Solomons, Maryland; shakedown at San Diego, September 1944. 29 January 1945 - San Antonio, Luzon landings; 31 January - Subic Bay and Grande Island landings (no enemy resistance). 15 February - inshore fire support for the Mariveles Harbor landings; flotilla then anchored as a screen across the mouth of Mariveles Bay. 16 February ~0320 - surprise attack by about 30 suicide boats plus heavy shore-based fire appearing to come from Caballo (page prints 'Cabello') Island; LCSs 7, 26 and 49 sunk 'in a matter of minutes' with the loss of 73 lives across the three ships and many wounded; LCS(L)-27 sank four boats, was badly damaged by a fifth, and was beached. A survivor account by LT(jg) Charles Trezona describes two hits about ninety seconds apart, port aft then starboard forward. The page carries a named list of the 25 LCS(L)-49 crewmen killed in the action.

- Finding
- A sister ship's action narrative (LCS(L)(3)-8, commissioned the same day at Lawley, Neponset) documents this hull's last anchorage and sinking as witnessed: on 15 February 1945 TU 78.3.8 (2 PCs, 6 LCI(R)s, 6 LCS(L)s) supported the Mariveles Bay assault; prior to sunset the LCS(L)s anchored in line as a screen between Gorda Point and Cockines Point, LCS-8 anchored 500 yards off Gorda Point with the other stations occupied respectively by LCS(L)s 7, 49, 27 and 26, all ships at Condition II. At 0310 on 16 February general quarters was sounded; 'Men and officers on watch claimed to have seen the LCS(L) 49 explode and sink within 30 seconds.' LCS(L)-7 rolled over and sank at 0345; LCS(L)-26 had already sunk. LCS-8 recovered a survivor of LCS-7 from the water and received five more via a PT boat.

- Finding
- The Landing Craft Support Museum's historian (also National Association of USS LCS(L) 1-130 secretary and the NavSource page contributor) documents: six LCS ships anchored across the mouth of Mariveles Bay as a security screen for the landings recapturing the southern Bataan Peninsula; Japanese shinyo suicide motorboats carrying roughly 600 pounds of high explosives each struck four of the six; three sank within minutes and the fourth (LCS-27) beached; 77 sailors were lost. The author's father, Ship's Cook 2/c Edward G. Steenbergen, had served aboard LCS-49 and left the ship days before it sank. The article states the dead 'are now entombed in the Landing Craft Support ships resting at the bottom of Mariveles Bay' - i.e., the wrecks are reported in place as of 2022. It preserves survivor Zenon Zembrzuski's account of the port-side hit and a second starboard explosion.

- Adjudicated asbestos-exposure record for this hull's builder: under the Longshore and Harbor Workers' Compensation Act, a shipyard carpenter who worked at Albina Engine & Machine Works (his Albina employment ending 1957), Willamette Iron & Steel, and Puget Sound/Lockheed died 22 September 2002 of left pleural mesothelioma; the ALJ found 'clear, credible, and unrebutted evidence' of asbestos exposure and, applying responsible-employer law, found Albina Engine 'was the last employer to expose decedent to asbestos and is the employer responsible for claimant's benefits.' The Benefits Review Board affirmed (third Board decision in the case; McAllister I, 39 BRBS 35 (2005); McAllister II, 41 BRBS 28 (2007)).

- Yard-level record, NOT a hull record: the adjudicated Albina exposure window (through 1957) post-dates this hull's 1944 construction, and LCS(L)(3)-49 is not named in the decision. Establishes that the builder yard is an adjudicated asbestos-exposure site in the mid-1950s; it does not establish materials installed aboard this hull in 1944, individual crew exposure, quantity, or present-day presence. Litigation stage: administrative merits finding affirmed on appeal (mature stage - not a pleading allegation).

- Finding
- Class/era inference: the LCS(L)(3) was a 158-ft, 250-ton (light) steel gunboat designed by George Lawley & Sons, Neponset, built in 1944-45 by three yards (Lawley; Albina Engine & Machine Works and Commercial Iron Works, both Portland OR), 130 hulls. This hull was one of Albina's wartime emergency-production craft (builder's no. 203) powered by General Motors 6-71-series diesels - no boilers and no steam plant. Era-standard asbestos applications aboard a small diesel combatant of 1944 were engine-exhaust lagging, machinery-space thermal/acoustic insulation, gaskets and valve packing, electrical insulation, and hot-surface board/sheet in machinery compartments; Navy-wide, the service did not substitute alternative insulation until the early 1970s (GAO HRD-80-2), well after this hull was built and lost. The hull went down with its complete as-built wartime fit and reportedly remains in place.

- Class/era and builder-yard inference only - NOT a hull-specific finding. No insulation survey, material list, or work package for this hull exists or is likely recoverable from the wreck. Product names are normalized era terms; no manufacturer attribution for this hull. The diesel plant means the boiler/turbine lagging pathway of steam vessels does not apply; any era-typical material aboard was confined to machinery-space, gasket/packing, and electrical uses.

CAVEAT: CourtListener could not be queried this session - the authenticated helper reported the fleet-wide request budget spent on repeated attempts; logged as blocked in search_ledger (sl-12), not as a negative result.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a gunboat sunk in action retains its as-built 1944 materials in the wreck, which was never salvaged, abated, or surveyed in any public record located. The litigation-repository search is a genuine open gap (fleet-paced, not run). Does not establish or defeat any claim of exposure or legal eligibility.

- CORRECTION of two circulating errors. (1) Geography: NavSource's disposition line reads 'sunk, at Mariveles Harbor, Leyte, P.I.' and Shipbuilding History's yard table reads 'sunk at Leyte Feb-45' - Mariveles is on the Bataan Peninsula, Luzon, at the mouth of Manila Bay, not at Leyte; the official CNO loss list records 'Off Luzon, P.I.' and all participant narratives place the sinking in Mariveles Bay. (2) Builder's number: Shipbuilding History's Albina table gives builder's hull no. 203 for LCS(L)-49, delivered/commissioned 31 August 1944 - consistent with NavSource's 31 August 1944 commissioning; uboat.net adds a 5 April 1944 order date (secondary compilation, unverified against the contract record).
