- NavSource records this hull as an SC-497-class submarine chaser: built by Calderwood Yacht Yard Inc., Manchester, MA; ordered 16 February 1942 (contract NOBs-529); laid down 26 March 1942; launched 25 September 1942; commissioned USS PC-692 on 25 November 1942; reclassified SC-692 in April 1943; transferred to France as CH-131 on 17 November 1944; later renumbered P-713 and M-713; struck from the Marine Nationale inventory as Q-420 on 8 February 1967; final disposition unknown. Specification block: 148 tons, 110 ft 10 in, 17 ft beam, 6 ft 6 in draft, 15.6 knots, complement 28; armament one 40 mm mount, two .50-caliber machine guns, two 'Y gun' depth-charge projectors, two depth-charge tracks; propulsion two 880 bhp General Motors 8-268A diesels, Snow and Knobstedt single reduction gear, two shafts. Call sign Nan-William-Zebra-Fox. Commanding officers: LTJG Edward P. Stafford, USNR (25 Nov 1942 - 13 Oct 1943); ENS Charles Shelby Coffey, Jr., USNR (13 Oct 1943 - 17 Nov 1944). Photo record: U.S.-service image credited to C. S. Coffey, Jr.; FNS Chasseur 131 underway probably off Toulon, 1950s; M-713 underway off Sfax, Tunisia, September 1956 - 'the M designation indicates use as a baliseur, or dan buoy layer to mark swept lanes through minefields.'

- Finding
- The NavSource index places SC-692 in the SC-497 class, described as 110-foot wooden-hulled World War II submarine chasers, and states 142 class chasers were used by U.S. Allies under the Lend-Lease Program; secondary class summaries (Wikipedia SC-497-class article, Pacific War Online Encyclopedia) put the French allocation at 50 hulls - this hull's own transfer to France is documented ship-specifically in ev-01/ev-02. The PC-692 label in the hull timeline is a commissioning designation (Nov 1942 - Apr 1943) for this wooden SC-type craft, not evidence that SC-692 was a PC-461-class steel patrol craft - the PC-461 class closed at 341 completed and 60 cancelled hulls and the 679-720 block was in neither series (batch scope note, re-scoped 2026-09-29). The record is carried as USS SC-692, with PC-692 retained as an alias.

Stafford, USNR); on 13 January 1943 YMS-36 and SC-692 were relieved by USS SC-659; Phoebe and escort arrived Gravesend Bay around 2030Q/15 January.

This is photographic evidence of SC-692's presence in Salerno harbor shortly after the September 1943 landings - corroborating her Mediterranean service under Stafford before his 13 October 1943 relief.

- The NAVPERS-derived listing credits SC-692 with three European-African-Middle Eastern engagement stars: E2 for 9-15 July 1943, E4-1 for 22 January - 8 February 1944, and E7 for 15 August - 25 September 1944. The official NAVPERS Part III code list maps E2 to 'Sicilian occupation' (9-15 Jul 43), E4-1 to 'Anzio-Nettuno advanced landings' (22 Jan - 1 Mar 44), and E7 to 'Invasion of Southern France' (15 Aug - 25 Sep 44). The E2 credit covers Stafford's Sicily service documented in his memoir; E4-1 and E7 fall under ENS Coffey's command in the year before transfer to France.

Credited stars establish presence in an operation, not ship-level detail; no asbestos content. E3 (Salerno landings) is NOT among the hull's credited stars.

- Finding type
- historical_record
- Finding
- SC-692's first commanding officer published a dedicated memoir of this hull's war. Edward Peary Stafford's 'Subchaser' covers, per the Splinter Fleet bibliography, 'the early days of the war, the makeup of convoys and their escorts, the crossing of the Atlantic requiring refueling at sea while underway, and operations in the Mediterranean theater'; the publisher's description identifies 'subchaser 692' as the book's subject and notes action during the July 1943 invasion of Sicily. Stafford's Contemporary Authors biography lists 'commanding officer, U.S.S. SC 692, in the Atlantic and Mediterranean theaters, 1943.' USNI News's appreciation confirms he 'commanded a subchaser in the Caribbean and Mediterranean seas' before service as executive officer of USS Abercrombie (DE-343); he was a grandson of Arctic explorer Rear Admiral Robert E. Peary and later a naval aviator, Pacific Fleet historian, and author of 'The Big E.'

[9]Dartmouth Alumni Magazine, February 1944 issue - contemporary dispatch on Lt. Edward Peary Stafford '42 USNR commanding a 110-foot subchaser in the Sicily and Salerno landing operations (adapted from the Washington Evening Star) [reputable_press]

- Finding type
- historical_record
- Finding
- A wartime (February 1944) alumni-magazine dispatch records that 'Lt. Edward Peary Stafford... as commanding officer of a [110]-foot subchaser with a crew of 26... took part in the landing operations in Sicily and Salerno.' The dispatch - adapted from the Washington Evening Star - recounts operational detail for this hull: ordered to a port north of Gela on the Sicilian coast to deliver two empty landing craft, the boat came under shore-battery fire and took three-quarters of an hour under constant fire to zigzag to safety; at Salerno Stafford described 'Whistlin' Joe,' a Nazi machine-gunner in the hills northwest of the beachhead. It records that in the Salerno and Gela operations none of his crew was injured (one man received a Purple Heart after a surprise air raid in Bizerte), that Stafford had been 'sent overseas last April' [1943] with official word of the Sicily landing four days beforehand, and that he had returned for the Miami Submarine Chaser Training Center. Stafford's only subchaser command was SC-692 (NavSource CO list; his own memoir).

- Alumni-magazine dispatch adapted from the Washington Evening Star (Nov 1943 dateline context) - a reputable contemporaneous secondary source, not an operational record; it does not name the hull number (attribution to SC-692 rests on Stafford's documented sole subchaser command). The OCR'd text renders '110-foot' as 'no-foot'. 'Salerno' participation per this dispatch is not matched by a NAVPERS E3 star credit for the hull (see ev-05/ev-06) - the sources are reconciled only to the extent carried here. No asbestos content.
