- Finding type

- Finding
- The official NARA inventory of Navy logbooks lists deck logs for 'LCI(L)-577' covering 3/23/1944 through 12/31/1945 (PDF page 25 of the by-ship-number list). The coverage start date equals her commissioning date (23 March 1944, NavSource/uboat.net), mutually corroborating it. This is the wartime Navy's own log inventory establishing in-scope service for this hull. The hull does not appear in NARA's published index of fully digitized deck logs, so these logs remain an undigitized archival lead at Archives II, College Park (RG 24).

Coverage ending 12/31/1945 reflects the collection's holdings cutoff, not the end of the ship's service (she was transferred to the Maritime Commission in December 1947). The logs were not individually read; any operational or material detail inside them is unexamined.

- Finding
- Independent data card confirming this hull: LCI-351 class; built by New Jersey Shipbuilding Corp. (Barber, N.J.); laid down 21 Feb 1944; launched 17 Mar 1944; commissioned 23 Mar 1944; 'Reclassified as LCI(G), Landing Craft Guns on 15 June 1944'. Three notable events transcribe operational orders of battle naming this hull: (1) Operation Globetrotter (Cape Sansapor-area landings, from 30 July 1944) - 'USS LCI(L)-577 (Lt.(jg) E.J. Morgan, USNR)' in Task Unit 77.2.5, the LCI Unit, among LCI Flotilla 8 craft (COMLCIFLOT 8, T/Cdr. F.B.C. Martin aboard LCI(L)-546); (2) Operation Tradewind (Morotai, 15 Sep 1944) - 'USS LCI(L)-577 (Lt.(jg) E.J. Morgan, USNR)' in Task Group 77.3.23, LCI(L)s of the Red Beach attack force; (3) Operation Oboe VI (Brunei Bay, 10 Jun 1945, from CTG 78.1's report) - 'USS LCI(L)-577 (Lt. E.J. Morgan, USNR)' in Task Unit 78.1.13 (LCI Unit, COMLCI(L)FLOT 8) and carried in the Reinforcement Unit Task Unit 78.1.19.

- Limitations
- uboat.net is a volunteer secondary compilation, not a primary registry - but its 'notable events' transcribe official orders of battle and operation reports. INTERNAL CONFLICT: the data card says reclassified LCI(G) on 15 June 1944, yet the same page's transcribed orders of battle style the ship 'USS LCI(L)-577' at Morotai (Sep 1944) and at Brunei Bay (Jun 1945), where the dedicated LCI(G) Unit (TU 78.1.32) lists hulls 69, 23, 64, 65, 68, 70 - not 577. The gunboat conversion date and even whether she operated as a gunboat in theater are therefore unresolved; NavSource leaves the date 'unknown' and records only the 10 Sep 1945 reversion. No asbestos content.

- The official Navy awards manual lists 'LCI(L) 577' with five engagement entries: 31 Jul 44 (P28-6), 1 Aug 44 (P28-6), 15 Sep 44 (P28-8), 19 Nov 44 - 29 Nov 44 (P31-1), 31 Jan 45 (P41-2). These operation codes map to the Western New Guinea operations (P28: Cape Sansapor, P28-6; Morotai, P28-8), the Leyte operation (P31-1), and Manila Bay-Bicol (P41-2: Nasugbu) - matching NavSource's three-campaign / three-battle-star accounting engagement-for-engagement.

- The official-ships roster lists 'LCI(G)-577 | 1944-45' among the Landing Craft, Infantry (Gunboat) in commission, corroborating that this hull was carried as a gunboat conversion within the 1944-45 window. The section head notes LCI(G)s were converted from LCI(L)s 'for close-in fire support of landing operations' with 2-3 40mm, 3-4 20mm, 6 .50 cal, and 10 Mk 7 & 2 Mk 22 rocket launchers, complement 5 officers and 65 enlisted, 8 GM diesels, twin screws.

The yard page describes New Jersey Shipbuilding as an LCI assembly line on Arthur Kill at Barber (later absorbed into Perth Amboy, now Maurer), managed by Todd Shipyards from 1942 at the Navy's request, closed after the war. shipbuildinghistory.com's identical table carries NO U.S. Official Number merchant trace for hull 577 (unlike some sister hulls) - consistent with NavSource's 'fate unknown' and with no post-1947 merchant chain being locatable for this hull.

- Government documentation of the LCI(L)-351 class design: Bureau of Ships standard design built for rapid wartime assembly-line production; welded 1/4-inch steel plate; two decks with the engine room below, containing four pairs of General Motors 6-71 diesel engines on two shafts with variable-pitch propellers; deckhouse accommodations, galley, mess, wardroom on the main deck; approximately 1,051 LCIs built in ten shipyards. LCI(L)-577 was built to this class design at one of those yards (New Jersey Shipbuilding).

The HAER and NRHP documents contain NO asbestos information; they do not establish that any LCI's insulation contained asbestos. -713 exemplifies the post-June-1944 modified design (centerline ramp, cylindrical pilothouse); LCI(L)-577, launched March 1944, carried the earlier configuration (side ramps, square conning tower).

- Finding type
- asbestos_application
- Finding
- A diesel-powered welded-steel landing craft built in early 1944 sits inside the Navy's documented asbestos era. Era-standard applications aboard a small diesel combatant of this period were diesel engine and exhaust insulation/lagging in the confined lower-deck engine room, machinery-space thermal insulation, gaskets, valve and flange packing, electrical insulation, deck coverings, and winch brake linings. As a diesel vessel she carried no steam plant - the boiler/turbine lagging pathway of larger ships does not apply, and total asbestos aboard (if present) would have been far less than on a steam vessel of the era.

CourtListener authenticated API v4 searches ran this session: opinion search '"LCI(L)-577" OR "LCI(G)-577" OR "LCI-577"' returned 0 hits; the same docket search returned 1 hit - 'Awala v. Jordan', 1:05-cv-00783 (D.

A variant-spelling opinion query was attempted but deferred by fleet pacing (see sl-13). Secondary web sweeps surfaced no qualifying case; the '577 asbestos' marketing surface belongs to USS Sproston DD-577 (law-firm pages) - name collision, excluded by source policy.
