- Coast Guard Historian's Office account of the loss of this Coast Guard-manned hull: on 1945-01-29 Serpens lay anchored off Lunga Point, Guadalcanal; LCDR Stinson, a junior officer, and six enlisted men were ashore while the crew loaded depth charges into her holds. The explosive cargo detonated; only the bow remained visible and it sank soon after. Killed: 197 Coast Guard officers and enlisted men, 51 U.S. Army stevedores, and Surgeon Harry Levin, U.S. Public Health Service; one soldier ashore killed by shrapnel. Only two men aboard survived - Seaman 1/c Kelsie Kemp and Seaman 1/c George Kennedy, in the boatswain's locker. Only two Coast Guardsmen's bodies were recovered intact and identified. Loss initially attributed to enemy action (three Purple Hearts issued); a Navy court of inquiry could not establish cause; by 1949 the Navy closed the case as not due to enemy action but 'an accident intrinsic to the loading process.' Remains exhumed from the Guadalcanal military cemetery and interred Arlington National Cemetery 1949-06-15; Serpens Memorial dedicated 1950-11-16. Ranks as the single largest disaster in Coast Guard history. Ship details given: EC-2 Liberty, MC hull 739, launched as SS Benjamin N. Cardozo, transferred to Navy and designated AK-97, commissioned San Diego late May 1943 under Lt. Cmdr. Magnus Johnson; 442 ft, 14,250 t., 11 knots; armament 1x5", 1x3", 2x40mm, 6x20mm; crew 19 officers + 188 enlisted; LCDR Perry Stinson assumed command late July 1944.

- Finding
- Official U.S. Army cemetery record: destruction of USS Serpens (AK-97) is 'the largest single disaster in the history of the United States Coast Guard.' The 14,250-ton ammunition ship exploded off Lunga Beach, Guadalcanal, British Solomon Islands on the night of 1945-01-29 while the crew loaded depth charges. ANC's count: 250 men lost their lives - 193 Coast Guard sailors, 56 U.S. Army soldiers, and Dr. Harry M. Levin, U.S. Public Health Service surgeon; only two bodies could be identified; ten crew members survived (eight ashore including LCDR Stinson, plus Seamen 1/c Kelsie Kemp and George Kennedy aboard, both awarded the Purple Heart). Initially attributed to a Japanese attack; a court of inquiry found no evidence of enemy action and in 1949 the Navy closed the case as 'an accident intrinsic to the loading process.' Dead originally buried at the Army, Navy and Marine Cemetery on Guadalcanal; reinterred Section 34, Arlington National Cemetery, 1949-06-15; octagonal memorial inscribed with names and ranks dedicated 1950-11-16; VADM Merlin O'Neill, Commandant of the Coast Guard, spoke at dedication.

- Finding
- Official sources publish three different casualty accountings for the same event: (a) DANFS (1976) - 198 crew members and 57 Army stevedores were aboard when Serpens exploded; only two aboard survived; NavSource's summary adds PHS physician Dr. Harry M. Levin and one soldier ashore killed by shrapnel (~257 dead). (b) Coast Guard Historian's Office - 197 Coast Guard officers and enlisted, 51 Army stevedores, and Surgeon Levin killed, plus one soldier ashore (~250 dead). (c) Arlington National Cemetery - 250 total: 193 Coast Guard sailors, 56 Army soldiers, and Dr. Levin. All sources agree on 2 survivors aboard (Kemp and Kennedy) and 8 crew ashore (10 total survivors). The ANC memorial figure of 250 is the commemorative count; component-level discrepancies remain unresolved in official records.

- Mirrored excerpt, engine-cylinder insulation section
- Finding type
- asbestos_application
- Finding
- The U.S. Maritime Commission instruction manual for the EC2-S-C1 plant - the design type of this hull - describes cylinder insulation of magnesia under sheet-iron lagging; insulation products of this era were commonly manufactured with asbestos fiber, and period steam-system gaskets, packing, and insulation felts commonly contained asbestos. Liberty-type hulls were built to emergency USMC specifications during the period when the federal government had reserved asbestos supply for shipbuilding. Typical applications for the type: boiler and steam-drum insulation; steam-line lagging between boiler room and engine room; valve and flange gaskets; machinery packing; insulation in accommodation spaces and around the galley; brake linings on winches and windlass.

- Limitations
- Class/design documentation, not a hull record - the manual names the EC2-S-C1 type, not this vessel, and does not itself state 'asbestos' content (magnesia lagging of the era was typically asbestos-fiber-reinforced; the manual text is silent on fiber). Asbestos presence aboard this hull is era inference, not ship-proven. Does not establish quantity, exposure of any individual, or causation. Adapted from class profile ev-ec2-s-c1-liberty-01.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and emergency program under which this EC2-S-C1 hull was mass-produced at Calship in 1943 - and that wartime demand drove unprecedented asbestos utilization aboard merchant-type hulls.

[7]DANFS, Serpens (AK-97) - exposure-relevant documented events: February 1944 New Zealand drydocking; July 1944 SF-1 radar installation at Purvis Bay; November 1944 conversion of three holds to ammunition stowage in New Zealand [nhhc_danfs]

- Finding
- Documented ship-specific events relevant to material disturbance: (1) ordered back to New Zealand for drydocking February 1944 before loading dry provisions; (2) at Purvis Bay July 1944 for installation of SF-1 radar; (3) after offloading in New Zealand mid-November 1944, three of her holds were converted for ammunition stowage - an interior reworking shortly before the loss. A Coast Guard-manned hull undergoing these documented events represents the era's construction/maintenance exposure population at Calship (1943 build) plus repair-yard and ship's-force maintenance populations.

- The drydock, radar-installation, and hold-conversion events are ship-specific and DANFS-documented; any asbestos disturbance scope within them is inferred from era practice, not documented per-hull. No asbestos, insulation, or materials statement exists for any of the three events. Does not establish exposure for any individual.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Serpens (AK-97) was found in the public sources searched - the hull was destroyed in 1945 and no surveyable fabric survives beyond the bow section on the seafloor. DANFS, the Coast Guard Historian's Office account, and the ANC memorial record contain no asbestos or insulation-material statement. CourtListener: authenticated API returned throttled mid-sweep (daily quota); domain-level search surfaced only generic MDL-875 filings and no hull-named asbestos opinion; two lead-generation directories list 'USS Serpens AK-97' in asbestos ship lists - marketing pages, classified non-qualifying and excluded.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 EC2-S-C1 hull is era-consistent with installed asbestos-containing materials, and the hull's destruction does not negate wartime construction/crew exposure pathways. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility. The CourtListener API throttle leaves the opinion sweep partially verified (domain-search coverage only) - flagged for a follow-up pass.

A hull destroyed in 1945 leaves its wartime paper trail as the only possible ship-specific materials record.
