   NavSource's live page for this hull (filed under its US number, YMS-207) records: laid down 16 April 1942 by Robert Jacobs, Inc., City Island, NY; launched 1 August 1942; 'Completed and commissioned USS YMS-207, 18 January 1943'; 'Transferred to France 16 March 1944 and named Petunia (D 271)'; 'Sold to France 21 March 1949'; 'Struck from the Naval Register 28 April 1949'; 'Reclassified D-354, D-06 and M-664'; 'Decommissioned 30 November 1961. Fate unknown.' The page header displays only the United States and Free French ensigns with the line 'YMS-207 served the Navies of the United States and France' - by NavSource's own flag convention (a genuinely British-served sister such as YMS-209 is badged 'BYMS-2209' with the UK and Greek flags) this hull is treated as never having served the Royal Navy. Call sign Nan-Queen-Roger-Victor. The specification block lists displacement 270 t., length 136 ft, beam 24 ft 6 in, draft 8 ft, speed 15 kts, complement 32, armament one 3"/50 dual purpose mount, two 20mm mounts, and two depth charge projectors, propulsion two 880 bhp GM 8-268A diesels with Snow and Knobstedt single reduction gear on two shafts. The page states 'There is no DANFS History currently available for YMS-207.'

Deck logs of commissioned Navy ships are permanent federal records held in Record Group 24; the indexed coverage documents continuous US Navy custody of this hull for its entire commissioned US service window.

   Limitations

   This is a finding aid showing indexed coverage spans of US Navy deck logs, not the logs themselves; it does not establish specific events, locations, or that every day in the window has surviving pages. It is strong (not conclusive) evidence of continuous US custody: a hull physically operated by the Royal Navy would not ordinarily file US Navy deck logs, though allocation paperwork and physical custody can diverge in Lend-Lease cases. The underlying logbooks were not reviewed. Establishes no asbestos or exposure fact.

   The caption is quoted via NavSource's transcription; the NARA catalog is JS-rendered and the 80-G original was not independently retrieved this pass (catalog query returned no usable response - logged as pending in the ledger). USN photo captions of the period were written by US photographers and can mislabel allied-operated hulls by their build designations; weighed together with the US deck-log coverage (ev-03), US operation at Salerno is the stronger reading. Establishes presence and activity, not asbestos exposure.

   Finding

   CORRECTION (identity conflict documented): The Naval Marine Archive fleet table for yard minesweepers lists 'YMS 207 | Robert Jacob | City Island NY | 136 | 320 | 18-Jan-43 | To Britain 1943 as BYMS 2207, to France 1944 as Petunia (D 354), decommissioned 1961' (the companion Robert Jacob yard table on both navalmarinearchive.com and shipbuildinghistory.com carries the same row ending 'scrapped 1963'). This is the only source family asserting the ship actually went to Britain as BYMS-2207 - the origin of the 'served as BYMS-2207' premise. The same site's class-table preface supplies the numbering rule: of the 150 boats transferred to the Royal Navy, 'the other 70 were transferred from the US Navy and given British pennant numbers 2000 greater than the U.S. number (e.g., YMS 162 became BYMS 2162). Another 30 boats were transferred to the Free French Navy in 1944.' YMS-207 and adjacent Robert Jacob hull YMS-208 were among the Free French transfers; the yard-table row most plausibly records the paper pennant allocation (BYMS 2207 = YMS number + 2000), not a completed transfer - contradicting NavSource's US+France flag attribution, uboat.net's US-Navy-only filing, and continuous US deck logs to 16 March 1944.

The 'To Britain 1943' entry conflicts with NavSource's commissioned-USS narrative, uboat.net's US-only filing, NARA deck-log coverage, and the Royal Navy flotilla roster's omission of BYMS-2207 (ev-08); the row is carried as the documented source of the BYMS-2207 designation, read as pennant allocation rather than evidenced transfer. Its 'D 354' and 'scrapped 1963' details likewise conflict in minor ways with NavSource (D 271 at transfer; 'fate unknown') - carried in gaps. No asbestos, material, or exposure content.

    Finding

    NavSource's Auxiliary Motor Minesweeper index establishes the class and transfer-program context for this hull's designations: 80 ships of the 136-foot YMS type were ordered specifically for transfer to Great Britain under Lend-Lease, carried on the Navy List as 'British Motor Minesweepers' (BYMS) numbered 1-80, and assigned British pennant numbers BYMS-2001 to BYMS-2080 on transfer; the class preface (per the Naval Marine Archive table) adds that a further 70 US-Navy-built hulls were transferred to Britain with pennant numbers 2000 greater than the US number, and that 30 boats were transferred to the Free French Navy in 1944 and 45 to the Soviet Union in 1945. The class was wooden-hulled, 136 ft, diesel-powered; US survivors were reclassified AMS with bird names in 1947.

    Limitations

    Class- and program-level context only: it explains why a YMS-207 could carry an allocated BYMS-2207 pennant and how the Free French transfers worked, but it does not state this hull's actual custody path - which the ship-specific rows address. No asbestos, material, or exposure content.

    Finding

    GAO's 1979 report Navy Efforts To Protect Workers From Asbestos Exposure is Navy-wide historical context for asbestos use and worker-protection efforts; it is retained only as era context for a Navy vessel constructed 1942-43 and commissioned January 1943.

    Limitations

    The report was not retrievable live because GAO returned HTTP 403 (confirmed 2026-10-04), so no detailed report proposition is attributed here. Navy-wide context cannot establish asbestos installation, product identity, quantity, condition, exposure, or causation aboard this wooden-hulled diesel minesweeper.

    Finding

    No ship-specific asbestos survey, abatement record, hazmat disclosure, product-identification record, or qualifying litigation naming this hull under any designation (YMS-207, BYMS-2207, J-1007, Pétunia, Tiare) was located in the sources reviewed for this batch. Ship-specific asbestos documentation is unknown.

    Limitations

    A bounded search result, not proof that records do not exist. NARA notes that many Navy records are not digitized; the SHD Petunia file (ev-10) and RG 24 deck logs (ev-03) are unreviewed primary holdings. The wooden hull and diesel plant mean no boiler or steam-turbine pathway is documented, but no class-era inference is used to claim or deny asbestos aboard this hull; French-era maintenance history (1944-61) is essentially undocumented in the reviewed sources.

    Finding

    CourtListener sweep (authenticated helper): three of four mandatory base queries completed plus one overflow-authorized asbestos variant. Exact-name opinion ("BYMS-2207", type=o) returned count 0. Exact-name docket ("BYMS-2207", type=r) returned count 25; all 20 page-1 hits classified - every one a name collision or unrelated litigation (a W.R. Grace bankruptcy docket, patent MDLs, habeas and civil-rights prisoner cases, contract and insurance suits, and a 2025 maritime-lien commercial case 'Pennantia LLC v. Rose Cay Maritime LLC'); none named the vessel, a minesweeper, or asbestos; five hits past the page unseen. US-hull opinion ("YMS-207", type=o) returned count 73; all 20 page-1 hits classified - pure token collisions (juvenile-initial 'Y.M.'/'YRM' anonymizations and number matches in Texas, Tennessee, Illinois and federal dockets); none named the ship or asbestos. The overflow-authorized variant ("YMS-207 asbestos", type=o) returned count 10; all hits classified - ten Texas appellate records matching token fragments, none containing the hull designation or asbestos content. The US-hull docket query ("YMS-207", type=r) and the overflow-authorized "BYMS-2207 asbestos" docket variant were declined by the fleet pacing gate across spaced attempts - access gaps, not zero-result findings. A separate secondary-web sweep for asbestos litigation naming this hull under any designation surfaced no qualifying case.

    Limitations

    Every completed query's returned hits were classified individually and none was qualifying, but coverage is bounded: the BYMS-2207 docket count (25) and YMS-207 opinion count (73) overflowed their 20-result pages, so 5 and 53 hits respectively remain unclassified at the hit level - the asbestos-qualified opinion variant (count 10, all collisions) mitigates this for YMS-207; the 'YMS-207' docket query and 'BYMS-2207 asbestos' docket variant returned pacing stand-down - access gaps, not negative findings. A hull of this size, era, and foreign disposition is an unlikely US litigation target, but the litigation question is not fully closed.
