- Finding
- Documented for this hull: laid down 21 May 1943 by Greenport Basin and Construction Co., Greenport, NY; launched 17 July 1943; completed 30 October 1943 and commissioned USS YMS-381; transferred to Norway 22 March 1945, reclassified NYMS-381, later named Begna (M 322); returned to U.S. custody 7 June 1948, transferred to the State Department, Foreign Liquidation Commission and sold to Norway the same day; struck from the Naval Register 12 August 1948; struck from the Norwegian Navy list 1966; fate unknown. Specifications: 270 t., 136' x 24'6" x 8', 15 kts, complement 32, one 3"/50 DP mount, two 20mm mounts, two depth-charge projectors; two GM 8-268A diesel engines ('880bhp' as printed - aggregate figure; class literature rates 440 bhp each), Snow and Knobstedt single-reduction gear, two shafts.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry; milestone dates generally track NVR/DANFS but the Norwegian strike year conflicts with other compilations (1966 vs 1961 - see gaps). The page's flag-key line erroneously reads 'YMS-377 served the Navies of the United States and Norway' - a copy artifact; the flag row and data apply to YMS-381. No asbestos or materials content. No DANFS entry exists for this hull (page statement; NHHC candidate URLs 404).

- Finding
- YMS-381's D-Day service is documented by a contemporaneous artifact collection surfaced in 2024: her commanding officer Lt. William E. Beckham Jr., USN kept his TOP SECRET-BIGOT Operation Neptune orders and the shrapnel-scarred 48-star flag flown from YMS-381 on 6 June 1944 (mailed home from Normandy September 1944 per customs documentation). Reporting identifies YMS-381 as a unit of Y-1 Squadron - the first-wave minesweepers clearing the assault channels off Utah Beach - which came under German gunfire after being spotted. uboat.net records Beckham's Bronze Star dated 6 June 1944 as CO of YMS-381 (source: personal communication). The collection was offered by Bayliss Rare Books in 2024 for the 80th anniversary.

- Norwegian national press documents this hull's post-transfer unit and mission: at the end of March 1945 the Royal Norwegian Navy took over four American-built minesweepers designated NYMS 379-382, which operated together as the 3rd Minesweeping Division (3. minesveiperdivisjon); from when they became operational they patrolled the English Channel, sweeping mines by day and on patrol service at night.

- Finding type
- asbestos_application
- Finding
- A wooden-hulled direct-drive diesel auxiliary motor minesweeper built mid-1943: no steam plant, so no boiler/turbine lagging pathway exists. Era-standard asbestos applications aboard a WWII small diesel combatant were confined to exhaust-system lagging, engine gaskets, valve packing, electrical insulation (Navy asbestos-insulated cable was standard), and winch/windlass brake linings. Small-craft asbestos loading was materially lighter than steel steamships', but WWII-era diesel machinery and electrical systems of this period still used asbestos-containing components.
