- NavSource is a volunteer secondary compilation; its milestones corroborate and are corroborated by Danish Naval History records (ev-02, ev-03). The 'fate unknown' line is outdated - Danish records document sale in 1976 and break-up at Aalborg in autumn 1990 (ev-03). The '1969' armament-reduction year conflicts with the Danish 'from 1963' (see gaps). Contains no asbestos content.

- Service timeline for this hull (translated from Danish): 6 September 1961 'Indgået i flåden' (entered the fleet) and 'Første kommandohejsning' (first command pennant hoisted); 7 January 1972 'Sidste kommandostrygning' (last command pennant struck - laid up); 30 August 1974 'Udgået af flådens tal' (removed from the fleet list - stricken); October 1976 'Solgt til A/S Danena og planlagt ombygget til civilt formål og henlagt på Limfjordsværftet i Aalborg' (sold to A/S Danena for planned conversion to civilian use, laid up at Limfjordsværftet in Aalborg); June 1989 'Udbudt til salg' (offered for sale); June 1990 'Lå fortsat på bedding på værftet i Aalborg sammen med MOSVIG og SÆLVIG. Planerne opgivet og fartøjerne ophugget i løbet af efteråret 1990' (still on the slipway at the Aalborg yard with sisters Mosvig and Sælvig; plans abandoned and the vessels broken up during autumn 1990).

- Royal Danish Navy crew (1961-72); A/S Danena and Limfjordsværftet trades (1976 lay-up through autumn-1990 break-up)
- Limitations
- This timeline supersedes NavSource's 'fate unknown': Danish records document break-up at Limfjordsværftet, Aalborg, in autumn 1990 with sisters Mosvig and Sælvig. It also resolves the 'decommissioned 1974' shorthand in English sources - the ship was laid up from 7 January 1972 and formally stricken 30 August 1974. Content verified via Wayback capture 20060108164334 (live page 503 to automated fetch). Whether asbestos or other hazmat was handled during the 1976 conversion work or the 1990 stripping/break-up is undocumented - no work or waste record was located.

[5]NavSource Motor, Coastal and Inshore Minesweeper Photo Index - MSI-1 through MSI-98 listing under the Mutual Defense Assistance Program offshore-procurement program; verbatim source line of the fleet-list name artifact [other_primary]
- Locator
- navsource.net/archives/11/05idx.htm - 'Inshore Minesweepers (MSI)' index, MSI-11 line and index preamble
- Finding type
- historical_record
- Finding
- CORRECTION: the fleet-list name 'USS Built in Denmark as' is a parsing artifact, not a ship name. NavSource's index line reads verbatim 'MSI-11 - Built in Denmark as Asvig (M 579)'; the list captured the connective text 'Built in Denmark as' as the name and dropped the actual vessel name. The hull was never a U.S. Navy ship: MSI-11 was a U.S. hull number assigned under the Mutual Defense Assistance Program offshore-procurement program to a minesweeper built at the Danish Naval Dockyard and delivered on completion to the Royal Danish Navy as Asvig (M 579). The index preamble explains the program: nonmagnetic minesweepers 'under construction for loan to foreign countries under the Military Defense Assistance Pact.' Secondary lists styling the MDAP hulls 'USS MSI-11' (e.g., the Wikipedia-derived 'List of mine warfare vessels of the United States Navy') apply a USS prefix these foreign-delivery hulls never carried - NavSource lists MSI-3 onward with no names or USS prefix precisely because they were never commissioned in the U.S. Navy. Same program sister: MSI-12 built in Denmark as Sandvig (M 581).

- Corrects a fleet-list naming artifact and the implied 'USS' prefix - both propagate from how secondary sources transcribe the MDAP hull list. The MDAP/offshore-procurement framing is NavSource's index text; authoritative program documentation (DoD MDAP records) was not separately located. No asbestos content.

'Danish design.' Class technical data as printed: displacement 180 standard / 200 full t; length 32.5 pp / 35.4 oa m; beam 7.20 m; draught 1.70 m; 2 diesels, 2 shafts, 1,100 hp; 14 kts; armament 1 x 1 - 20/70 Mk 10 plus mechanical, magnetic, and acoustic minesweeping gear; NWS-3 radar; complement 14.

[7]Era inference built on: NavSource MSI-11 specifications (two Werkspoor diesels, non-magnetic shallow-water sweeper); Danish Naval History specifications (same plant; VIG-class note 'non-magnetic minesweeper designed for mine sweeping in shallow waters'); era-standard product categories documented for small naval combatants of the period [other_primary]

- Finding type
- asbestos_application
- Finding
- No asbestos survey, material list, or work package exists for this hull in any located source. By era inference only: a small diesel-powered naval minesweeper completed in Denmark in 1961 sits inside the period when asbestos was standard across Western naval construction for thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation - including aboard small combatants. Diesel plant: the boiler/steam-turbine lagging pathway of steam vessels does not apply. The 20-man complement in a 193-ton hull implies a small machinery volume with confined-space exposure dynamics for engine-room ratings during operation and maintenance.

Royal Danish Navy and Orlogsværftet asbestos practice is an open archival question (Danish leads in ev-08). Does not establish materials aboard this hull, individual exposure, quantity, or present-day presence.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming MSI-11 / Asvig (M 579) was found in the sources searched. This hull also lacks the usual U.S.-Navy documentation trail entirely - no DANFS entry exists (NavSource: 'There is no DANFS history currently available for MSI-11'), no Naval Vessel Register entry exists (SHIPSDETAIL_MSI_11 request redirects to the NVR index; the hull was never a U.S. Navy ship and was disposed from Danish service in 1974), and no U.S. crew ever served aboard. Secondary web sweeps surfaced no asbestos assertions at all - not even law-firm marketing content, which typically mirrors NavSource/Wikipedia hull lists but has not propagated to MDAP foreign-delivery hulls. CAVEAT: CourtListener could not be queried - API returned HTTP 429 daily-quota-exhausted (~5.3 h to reset); logged as blocked in search_ledger, not as a negative result.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - Danish construction-era documentation (Orlogsværftet build specifications, RDN maintenance records) is undigitized, and the litigation-repository search is a genuine open gap (throttled, not run). A Danish-flag, Danish-crewed vessel would rarely surface in U.S. court repositories regardless. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- Primary documentation for this hull sits in Danish archives, not U.S. ones: Royal Danish Navy ship logs ('kommandodagbog') and Orlogsværftet construction/outfitting records would be held by Rigsarkivet; the Danish Naval Library archive already holds the service photography transcribed onto navalhistory.dk (photo credited to the Naval Library archives; class photo to E. Laursen / Gunnar Olsen archive). No U.S. National Archives trail exists - no RG 24 deck logs, never a USN hull. Separately, the Danish naval-vessels society's published corrections note that ASVIG 'blev søsat med PT-nr. M 580... Nummeret blev ændret inden færdiggørelsen' (was launched with pennant no. M 580; the number was changed before completion) - consistent with the anomaly that the earlier-built boat carries the lower pennant M 579 while later-launched Mosvig kept M 580.
