[1]Dictionary of American Naval Fighting Ships, 'Calypso' (III) (AG-35) entry. Live NHHC page returned 404 on 2026-09-20 (link rot documented in BATCH-01); hazegray DANFS transcription used. [nhhc_danfs]

- DANFS Calypso (III) entry, hazegray transcription at /danfs/auxil/ag35.htm. Transcription's data line reads 'AG-36: dp. 357 l 165' b. 25'3" dr. 13'2" s. 16 k. cl Potomac' - the AG-36 header is a transcription artifact on an AG-35 entry; displacement/draft figures conflict with USCG cutter-file values (see correction row).
- Finding type
- vessel_history
- Finding
- DANFS records the third Calypso (AG-35) launched 6 January 1932 for the Coast Guard by Bath Iron Works Corp., Bath, Maine; transferred from the Coast Guard to the Navy 17 May 1941 and commissioned the same day, Chief Boatswain J. H. Keevers in command. Based at Washington Navy Yard as tender to her sister ship, the presidential yacht Potomac (AG-25), she operated mainly on the Potomac River and Chesapeake Bay until 22 July 1941, when she sailed on a cruise to Nova Scotia; President Franklin D. Roosevelt was aboard for a portion of that cruise, bound for the Atlantic Conference at Argentia Bay, Newfoundland. She returned to Washington 23 August 1941 and was decommissioned 20 January 1942 and returned to the Coast Guard.

- USCG Historian's Office cutter file: built by Bath Iron Works, Bath, Maine ($258,000); launched 1 January 1932; commissioned into USCG 16 January 1932. Homeported Stapleton, NY (Special Patrol Force); transferred to San Diego 2 February 1934; Bering Sea Patrol April-September 1935; Baltimore from 10 September 1937. Transferred to the Navy 17 May 1941 as escort for presidential yacht Potomac at Washington Navy Yard; returned and recommissioned as USCG cutter 20 January 1942, rearmed with added ASW/AA weapons and sonar for Atlantic Fleet convoy escort. Rescued 42 survivors of SS Buarque (15 Feb 1942), 54 of SS Arabutan (8 Mar 1942), 13 of SS Pipestone County (7 May 1942), and 60 of USS Plymouth (PG-57) (5 Aug 1943). Reported to Norfolk for the new Air-Sea Rescue Service June 1944. Sold 2 November 1955 to A.T. Davies of Birchfield Boiler, Inc., Tacoma, WA for $15,564. Specs: 337 tons full load (1933; 350 in 1945); 165' oa x 25'3" x 7'8"-10'; two Winton Model 158 diesels, 1,340 bhp; 16 knots.

- Limitations
- Authoritative USCG history and specifications. Internally inconsistent on final decommissioning - data block says 18 July 1947, narrative says 'decommissioned for the final time on July 25, 1948' with storage at Coast Guard Moorings, Cape May, as a recruit-training aid; logged unresolved. Contains no asbestos or insulation-material statement; supports no asbestos claim.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding and that the wartime program drove unprecedented asbestos utilization aboard U.S.-built hulls - the construction era and federal-building context into which this Bath Iron Works-built 1932 cutter falls.

- Contemporaneous 1935 trade-press description of the 165-ft cutter class's construction (quoted verbatim in the USCG historian file) records the material plant: two 670-hp Winton diesels, twin-screw, and 'genuine wrought iron pipe' for fuel oil, lubricating oil, water service, fire and bilge systems, and 'the steam heating system' - establishing that this diesel-powered class carried a steam-heating system (a lagging-relevant installation) while making no statement about insulation composition or asbestos anywhere in the quoted description.
