- Limitations
- Official Navy history (DANFS), ship-specific and verified - but the live NHHC page 404'd on 2026-09-20 and the text was taken from a Wayback capture; the entry omits the final decommissioning date entirely (1946-05-27 comes from secondary compilations); its reduced-commission date (11-17) conflicts with shipscribe/NavalCoverMuseum (11-07); contains no asbestos or materials information whatsoever.

- Ship data line for AGP-16: reclassified 1944-08-14; builder Chicago Bridge, Seneca; keel 1944-08-15; launch 1944-10-27; commissioned 1945-05-14; decommissioned 1946-05-27; struck 1947-06-10; disposal 1948-02-06 (Maritime Commission disposal). Ship note, verbatim: 'Ex LST-773 14 Aug 44. Ferry commission as LST-773 7 Nov-5 Dec 44. Converted by Maryland DD, Baltimore (begun 6 Dec 44). Sold by MC as LST-773 for scrap.'

- Limitations
- Secondary specialist compilation drawn from primary BuShips/OpNav records - the 1946-05-27 decommissioning rests on this table (with NavalCoverMuseum and hazegray agreeing) since DANFS omits it; the ferry-commission start (11-07) conflicts with DANFS (11-17) and is unresolved; NavSource separately prints 10-27 (the launch date) as the reduced-commission date, an apparent conflation. No asbestos content - documents events only.

- Finding type
- vessel_history
- Finding
- Class documentation: all Portunus-class units were converted at Maryland Drydock Co., Baltimore, except AGP-5 (Tampa SB Co.); Gibbs & Cox was design agent for the LST conversion designs; the class was designed with shops and equipment for maintenance of one MTB squadron; the last five units (AGP 14-18, including Antigone) were modified similar to the CORONIS (ARL-10) class - bow doors retained, deckhouse moved forward to increase repair-shop space, 3"/50 gun deleted, 60-ton 'A'-frame hoist fitted (AGP-16 carried one, to port). Machinery for the class: G.M. diesels, 2 screws, 1,800 hp.

- Limitations
- Class-level conversion/design documentation - establishes conversion scope and machinery type for the class, not a materials list for this hull; the interior rework it describes (repair shops, berthing for a squadron-support role) is the context for era-consistent insulation inference, not a ship-specific finding. No asbestos content.

- 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 program under which this 1944 hull was built (Chicago Bridge & Iron) and converted (Maryland Drydock, 1944-45).

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST-542-series hull converted to a motor torpedo boat tender: no boilers, so the steam-lagging pathway is narrowed - asbestos-relevant applications for the type concentrate in GM diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings, bulkhead and accommodation insulation, machinery packing, and winch/crane brake linings; the documented 1944-45 conversion added enclosed repair shops and berthing, interior scope consistent with era insulation practice.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Antigone (AGP-16) or LST-773 was found in the public sources searched. The litigation check is INCOMPLETE: CourtListener's opinion API returned HTTP 429 (125/day limit, retry-after ~9.4 hours) and the web UI returned HTTP 403 on 2026-09-20; per rate-limit discipline the query was logged as blocked rather than retried.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - and here it does not even establish absence of litigation, because the CourtListener check was blocked rather than empty. The ship was scrapped in 1948, which forecloses museum-era survey/abatement disclosures of the kind available for preserved hulls. Does not establish or defeat any claim of exposure or legal eligibility.
