- NavSource record for this hull (live navsource.net page verified 2026-09-30): originally authorized as APM-4 (Mechanized Artillery Transport), reclassified Dock Landing Ship LSD-4 on 1 July 1941; laid down 23 November 1942 at Moore Drydock Co., Oakland; launched 2 April 1943; commissioned USS Epping Forest (LSD-4) 11 October 1943; redesignated Mine Countermeasures Support Ship MCS-7 on 30 November 1962; decommissioned and struck from the Naval Register 31 October 1968; sold for scrapping 30 October 1969. Campaign tables: six Asiatic-Pacific campaigns (Marshall Islands, Hollandia, Western Carolines/Peleliu, Marianas/Guam, Leyte, Okinawa Gunto), five Korean War campaign periods, Armed Forces Expeditionary Medal and Vietnam Service Medal campaign entries 1961-1968 (Advisory Campaign periods beginning November 1961 while still LSD-4). Specifications as reported by the Office of Naval Intelligence, 7 April 1944: displacement 4,032 light / 7,930 seagoing-loaded; propulsion two Skinner Uniflow 5-cylinder reciprocating steam engines with two Babcock & Wilcox oil-fired D-type boilers (250 psi), twin propellers, 7,400 shp; complement 17 officers + 237 enlisted, troop accommodations 22 officers + 218 enlisted; portable-deck helicopter capability described. Photo captions document the hull at Mare Island Naval Shipyard in November 1953 at the start of an overhaul when her helicopter deck was added (US Navy photo via Vallejo Naval and Historical Museum), and serving as mothership to mine destruction boats in Wonsan harbor 27 February 1953.

- NHHC photograph catalog page NH 66762-KN (live 2026-09-30) documents the ship's MCS-7 identity: 'Insignia: USS EPPING FOREST (MCS-7). Insignia adopted in 1962-63, upon the ship's conversion to MCS-7' - official NHHC corroboration of the conversion timeframe given by NavSource (redesignated 30 November 1962). The same catalog describes the ship's mission 'as flag and support ship to the smaller minesweepers.'

[4]Era inference built on: DANFS spec block and history; NavSource ONI specifications (7 April 1944) for this hull's steam plant; GAO HRD-80-2 program context (separate row) [other_primary]

- Inference row - no single source; plant description from NavSource ONI block; era practice from GAO HRD-80-2
- Finding type
- asbestos_application
- Finding
- This hull's documented steam plant - two Skinner Uniflow 5-cylinder reciprocating steam engines with two oil-fired Babcock & Wilcox D-type boilers - is of the type and era in which asbestos insulation was standard Navy practice: boiler and drum insulation, steam-line lagging, valve and flange gaskets, machinery packing, thermal insulation in machinery and accommodation spaces, and brake linings on winches and windlass were era-typical asbestos applications aboard 1942-43 naval auxiliaries.

- Limitations
- Class/era inference only - no ship-specific document states that asbestos was installed aboard this hull, where, or in what quantity. Does not establish individual exposure or causation. The hull was sold for scrapping in 1969, so present-day presence is moot; the question is historical exposure of crew and yard workers 1943-1968.

[5]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]

- GAO product page, Highlights section (live 2026-09-30; full report hrd-80-2.pdf, 26 pages)
- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s; the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed to accomplish repairs, modified in 1979 to include selectively replacing asbestos insulation in high-maintenance areas. GAO's fieldwork yards were Long Beach and Norfolk Naval Shipyards - Long Beach being where this hull was decommissioned and placed in reserve in 1947 (per DANFS).

- Program-level documentation spanning this hull's entire service life (1943-1968). GAO's fieldwork reviewed yard conditions in the late 1970s and does not document this hull, this inactivation, or any asbestos condition aboard this ship. The Long Beach overlap is a yard association, not a hull finding.

- Archival hit: NARA's digitized Navy deck-log index (RG 24, 'Navy Deck Logs Available in the National Archives Catalog') carries an 'Epping Forest (LSD-4/MCS-7)' section listing monthly digitized deck logs for every month January 1956 through October 1968 (the decommissioning month) - an unusually complete late-career digitized run covering the San Diego yard-availability period, the 1959-60 overhaul, the MCS conversion era, Sasebo homeporting, all Vietnam deployments, and inactivation. Logs for 1943-1947 (WWII and first inactivation) and 1950-1955 (Korean War, Mare Island overhaul) are not in the digitized index and remain paper-only in RG 24.

- Limitations
- The digitized logs exist and are individually cataloged; their contents were not page-read for this record. Deck logs would document yard periods, availabilities, repair activity, and the 1967 typhoon damage relevant to any exposure reconstruction, but nothing in this row is an asbestos finding. WWII-era and Korea-era logs are not digitized.

- Veteran-researched unit history hosted on NavSource (Ed Sinclair, 'Epping Forest History Supporting Mine Sweeping Boats', ~2011, based on MSB ONE/MinDiv 33 muster rolls and >400 veteran interviews): Mine Sweeping Boat Division ONE was transported aboard this hull December 1951-January 1952, February-March 1953, and May-June 1953 per muster rolls; the hull was transferred from Amphibious Command to Mine Flotilla 1 in 1960 and redesignated MCS in November 1962, making the 'minesweeping mother ship' concept permanent; OPNAVNOTE 1650 is cited as listing eighteen Vietnam trips for the ship, November 1961 (as LSD-4) through August 1968 (as MCS-7); during Typhoon Dinah 26-30 October 1967 all ten embarked MSL minesweeping boats were destroyed in the flooded well deck, ~50 hours at general quarters, hull inspected by USS Grasp divers, returned to Sasebo under own power 30 October 1967; decommissioned at Sasebo, Japan 31 October 1968; 'sold to the Japanese at Sasebo, for scrapping in 1969.'

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Epping Forest (LSD-4/MCS-7) was found in the public sources searched (see search_ledger). CourtListener authenticated opinion searches '"Epping Forest" asbestos', '"LSD-4" asbestos', and '"MCS-7" asbestos' each returned zero results (2026-09-30); a bare '"Epping Forest"' opinion search returned 7 hits, all name collisions (the Virginia estate's trust/tax and property litigation - Du Pont Testamentary Trust, Caldes v. Elm Street Development, and similar), none naming the ship; the docket-type search was blocked by fleet pacing limits and is logged as blocked, not negative.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 steam auxiliary retaining era-typical materials is the reasonable expectation, and the hull was scrapped in Japan in 1969-70 where no survey was located. The litigation picture is nearly but not fully closed: asbestos-qualified opinion searches for ship name and both hull numbers returned zero, and the bare-name sweep produced only estate-litigation collisions, while the docket-type query was pacing-blocked; blocked queries are disclosed, not counted as negative results. Does not establish or defeat any exposure claim or legal eligibility.

- Finding
- CORRECTIONS across sources: (a) First-decommissioning location - DANFS says 'decommissioned and placed in reserve at Long Beach 25 March 1947'; NavSource's narrative says 'Decommissioned, 25 March 1947, at San Diego, CA. Placed in Reserve at Long Beach CA'; Wikipedia's infobox says 'Sasebo, Japan' - impossible, the ship's Sasebo homeporting began 1960; DANFS carried, both variants logged. (b) Final decommission/strike date - NavSource '31 October 1968' matches Sinclair's Sasebo decommissioning account and Wikipedia's own infobox, while Wikipedia's body text says '1 November 1968' (an internal inconsistency); 31 October 1968 carried. (c) WWII battle stars - NavSource displays 'six' (matching its 6-campaign Asiatic-Pacific table) while Wikipedia's body says 'eight' and its ribbon list shows Asiatic-Pacific (8); NavSource carried, conflict logged. (d) MCS-era designation typo - NavSource's commanding-officer table prints 'MSC-7' for post-1962 rows; the designation was MCS-7 (NavSource header and NHHC NH 66762-KN). (e) Name misspelling - 'Epping Forrest' (double-r) appears on NHHC's own NH 66762-KN catalog text and period US Navy photo captions; carried as alias only.
