- NavSource timeline for this hull: laid down 8 December 1942 by Greenport Basin and Construction Co., Greenport, NY; launched 27 February 1943; completed 26 July 1943; commissioned USS YMS-375; damaged by a mine 8 October 1944 off Brest, France; struck from the Navy Register 19 February 1948; sold to Turkey 10 May 1948. Specifications: displacement 245 t.; length 136'; beam 22' 9"; draft 6' 3"; speed 14.5 kts.; complement 50; armament one 3"/50 dual-purpose mount and two 20mm mounts; propulsion two 880bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts. Photo captions document: the ship in dry dock undergoing repairs from mine damage; inscription 'YMS-375 after being damage[d] by mine off Brest, France Oct. 8, 1944'; a painted mine scoreboard on the stack (swastikas for mines destroyed, '8' ball for the mine that damaged the ship); a Chesapeake Bay photo credited to crewman Arthur Plumstead, S1/c USNR (1944-46); and the three-page QST article by her executive officer (see ev-04). Page also states: 'There is no DANFS History currently available for YMS-375.'

- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track official records but the page's naming of the Turkish transfer as 'TCG Kozlu (M 513)' conflicts with Navypedia and the Conway's-derived fleet list, which assign Kozlu to ex-YMS-348 and record this hull as Küllük (M-515) renamed Karamürsel (see ev-08).

Notable event: 26 January 1945, 'LST return convoy No.3' departed Cawsand Bay (Plymouth) with ten LSTs, seven YMSs (YMS-346, -348, -349, -351, -352, -356, -375), and Norwegian tanker Chr. Th. Boe, escorted by USS Gillette and USS Henry R. Kenyon; YMS-375's commanding officer is listed as Lt. E.C. Darnell, USNR; the Norfolk section (all LSTs, YMS-349, and YMS-375) entered the Norfolk swept channel 17 February 1945.

- Finding
- The U.S. Navy operation plan for the Normandy assault names this hull: the task organization for the Utah Beach assault force lists 'Y1 Flotilla 305, 356, 358, 375, 377, 378, 379, 360, 381, 382, 406(F)' - 11 YMS-type minesweepers under Assault Force 'U' alongside the 14th and 16th Fleet MS Flotillas, 'A' Flotilla, the 132nd M.S. Flotilla, and Y2 Flotilla (YMS 346, 347, (F) 348, 349, 350, 351, 352), with Landing Force 'U' (VII Corps, 4th Division). YMS-375 is therefore documented as an assigned unit of the Western Naval Task Force minesweeping organization for Operation NEPTUNE, June 1944.

- Finding
- Contemporaneous firsthand narrative of this hull's European service by her executive officer: orders for overseas duty March 1944; departed the United States 3 April 1944 in 'a huge convoy,' a 22-day crossing, putting in at Falmouth; work-up in formation sweeping; staged from Plymouth under air raids; departed 3 June through the sea-gate as 'the first ships in the convoy'; swept and buoyed the assault channel starting 60 minutes before H-hour on D-Day under shore-battery fire within 1,000 yards of enemy emplacements ('we would be the first ships in'), the squadron reporting its operation '98 per cent successful'; then weeks of continuous sweeping off the beachhead - clearing channels, opening new anchorage areas for supply ships, exploding 'mine after mine' - and clearing captured harbors as the Allied advance progressed, mostly operating independently of British sweepers. Article is credited to her XO (NavSource caption and handwritten provenance note on the scan).

- The standard published history of U.S. Navy mine warfare records the October 1944 clearance of the approaches to Brest: British minesweepers assisted by USS YMS-352 and USS YMS-375 swept the port approaches over 3-15 October 1944, and YMS-375 was damaged by a mine explosion on 8 October; in Brest's inner waters (Rade d'Abris and Port de Commerce) the sweepers destroyed 24 influence mines and 2 moored mines. Corroborates the NavSource mine-damage line and repair photographs.

- vessel_history
- Finding
- Turkish-fleet documentation of this hull's post-US career: 'Küllük (ex-YMS375), 1950s- Karamürsel,' pennant M515, built Greenport Basin, laid down 12.1942, launched 27.2.1943, completed 7.1943, entered Turkish service 2.1948, discarded 1966. Navypedia's US-side YMS registry independently records 'stricken 2.1948, to Turkey (Küllük).' The Conway's-derived Wikipedia 'List of mine warfare vessels of the Turkish Navy' independently lists the ex-US YMS-type 'K class' including 'Karamürsel ... Ex-Küllük, Ex-USS YMS-375.' Confirms the QA-flagged correction: the hull was transferred to Turkey in February 1948 as Küllük (M-515), renamed Karamürsel in the 1950s, and discarded in 1966.

[9]Designation cross-check: NavSource 11/19375.htm and uboat.net ship/9794 ('sold to Turkey 10 May 1948 ... TCG Kozlu (M 513)') vs Navypedia tu_ms_kas.htm ('Küllük (ex-YMS375) ...

- Finding type
- historical_record
- Finding
- CORRECTION: the two most-accessed secondary registries (NavSource, uboat.net) identify the Turkish transfer of this hull as 'TCG Kozlu (M 513).' Two other fleet references - Navypedia's Turkish KAS table and the Conway's-derived Wikipedia fleet list - instead record YMS-375 as TCG Küllük (M-515), later renamed Karamürsel, and assign the name Kozlu to ex-USS YMS-348 (Gibbs Gas Engine hull). The Kozlu attribution to this hull is therefore a likely NavSource-originated error that uboat.net repeats; the Küllük -> Karamürsel chain is carried in this record.

- Limitations
- Resolves a name conflict between secondary sources, not a primary-record finding; the underlying US transfer paperwork (e.g., MDAP/sale instruments) was not located and could settle which Turkish name the hull actually received. A 1960 NavSource photo captioned 'TCG Kozlu (M 513)' at Yassiada Island depicts the Kozlu hull (ex-YMS-348 per the table) and is not evidence about this hull's Turkish name.

- asbestos_application
- Finding
- A wooden-hulled diesel motor minesweeper built 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this period were engine-exhaust and machinery lagging, gaskets, valve packing, electrical insulation, and winch/windlass brake linings in the confined hull volume. As a wooden-hulled diesel vessel she carried no steam plant and no boiler/turbine lagging pathway - the asbestos-relevant material load aboard this type was materially lower than aboard steam vessels of the era.
