- Finding
- Compiled record for this hull: PC-461-class submarine chaser laid down 24 December 1942 at Commercial Iron Works, Portland, Oregon; launched 23 January 1943; commissioned USS PC-785 9 October 1943; placed in service in July 1946 as a Naval Reserve training vessel in the 9th Naval District (Great Lakes); named Frostburg in February 1956; 'Fate unknown.' Specifications: displacement 450 t; length 173'8"; beam 23'; draft 10'10"; speed 20.2 kts; complement 65; armament one 3"/50 dual-purpose gun mount, one 40mm gun mount, five 20mm guns, two rocket launchers, two depth-charge tracks; propulsion two 1,440-bhp Hooven-Owen-Rentschler R-99DA diesel engines, Westinghouse single reduction gear, two shafts. Call sign Nan-Uncle-Tare-Peter. The page carries a photograph captioned 'c. 1945 Adak, Alaska (Right to left) PC-793, PC-784, PC-785, PC-781, and an unknown PC' - direct photographic corroboration of Aleutian-area service in the closing war years. NavSource explicitly notes 'There is no DANFS History currently available for Frostburg (PC 785).'

- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates track NVR/DANFS-style records while the underlying Navy records sit at NARA (see ev-04 through ev-06). Contains no asbestos or material content. The Adak caption is a contributor-submitted photo caption (Harry Wilson, GM2, USN via Allan M. Wilson) - strong but non-official corroboration of Aleutian presence, dated only 'c. 1945.' 'Fate unknown' is the compiled disposition - no official disposal record corroborates any particular end.

Commanding officers for the WWII window: R. A. Turrentine, USNR (9 Oct 1943 - mid 1944); John W. Shinners, USNR (mid 1944 - early 1945); John P. Hinckley, USNR (early 1945 - late 1945).

The same table places PC-785 in a serial yard run - hull 56 = PC 783 (delivered 14-Aug-43, 'Sold 1948'), hull 57 = PC 784 (17-Aug-43, 'Sold 1948'), hull 59 = PC 786 (30-Oct-43, 'To Taiwan 19..') - establishing the yard as a serial Navy patrol-craft builder in the same wartime window, and showing that PC-785's row, unlike her sisters', carries no disposal notation.

- Finding type
- historical_record
- Finding
- This hull's complete commissioned-era muster-roll run is digitized (9 October 1943 - 16 July 1946). Forwarding sheets read directly fix her station at four points: (1) roll dated 31 December 1943 forwarded 10 January 1944 'From Section Base, San Diego, California' - signed R. A. Turrentine, Lt., USNR, Commanding Officer, J. W. Shinners, Lt.(jg), USNR, Executive Officer - so the ship spent late 1943 attached to the San Diego Section Base (11th Naval District); (2) roll dated 1 July 1945 forwarded 3 July 1945 'From Section Base, Bishop's Point, Pearl Harbor, T.H.' - signed John P. Hinckley, Lieut., (D), USNR, Commanding Officer, J. M. Moran, Lt.(jg), (D), USNR, Executive Officer; (3) roll dated 1 January 1946 forwarded 10 January 1946 'From Florida Group - Sixteenth Fleet, Green Cove Springs, Florida' - signed J. M. Moran, Lieut., (D), USNR, Commanding Officer - placing the hull in Atlantic Reserve Fleet inactivation custody after Key West; the accompanying roll page lists a single enlisted man (BROWN, Donald Aldrich, F1c(IC),(MoMM), USN) with distribution to 'Comdr., FLAGRP., Green Cove Springs, Fla.' - a one-man caretaker crew; (4) the final roll (ending 16 July 1946) is a reduced-status report of sailing signed by Ens. H. W. Bost, (D), USNR, as Commanding Officer with only Ens. W. D. McKee and Lt.(jg) D. H. Windfelder aboard - a caretaker complement at transition out of commission. The Q4-1943 roll cover carries an archivist annotation 'Comm 10-9-43 to 7-16-46 Decomm 7-16-1946' matching the file's end date.

- All hands 1943-46 (muster-roll span); reduced caretaker complement by mid-1946
- Limitations
- Muster rolls document who served aboard and where the ship administratively sat at roll dates - not operations between rolls and not materials. The December 1943 San Diego and July 1945 Pearl Harbor readings are direct image reads; the interval between them (including the Aleutian period evidenced by the Adak photo) is not covered by any forwarding sheet read this session - rolls between those dates were not individually examined. An early-1946 report-of-changes page sends one man to 'U.S. Naval Hospital, NavAirSta., Jacksonville, Florida,' consistent with Green Cove Springs custody but not itself a station entry. 'Decomm 7-16-46' is a later archivist's annotation on the roll cover, corroborated by the file's end date and by NavSource's 'placed in service July 1946' - the formal decommissioning order itself was not located.

- The personnel-diary file for the Naval Reserve training ships at Saginaw, Michigan - the program PC-785 served after decommissioning (NavSource: 'placed in service in July 1946 as a Naval Reserve training vessel in the 9th Naval District (Great Lakes)') - is digitized at NARA and is returned on a quoted 'PC-785' catalog search, i.e., the hull is named in the file's indexed text. Opening frames are the organization's daily personnel diary (certified by LCdr. H. L. Schust, USNR) covering June 1947 onward.

- Finding type

- Finding
- PC-785 appears nowhere in the official Pacific Fleet organization of 1 May 1945: the Service Squadron Two / naval-district patrol-craft block lists PC-776, PC-777, and PC-779, then resumes at PC-800 through PC-825 - the 780s (including PC-785) are absent. Combined with the c.1945 Adak photograph (ev-01) and her 1 July 1945 muster roll forwarding from Pearl Harbor (ev-04), this is consistent with an Aleutian-area assignment that ended with a transfer to the Hawaiian Section Base in the May-June 1945 window.

The Aleutian-inference chain (Adak photo + absence here + Pearl Harbor presence by 1 July) is corroborative, not a documented station entry for the 1944-45 interval, which remains the record's open window.

- Finding
- PC-785 does NOT appear in the official NAVPERS 15,790 (Rev. 1953) list of ships authorized campaign participation credit and battle stars: the patrol-craft block runs through the 500s-600s (PC-589, PC-653, PC-686) then resumes at PC-800 and PC-802 - the entire 700-block is absent, meaning the ship earned no WWII battle stars, consistent with escort/patrol duty outside designated assault operations.

- Finding
- A steel-hulled diesel patrol craft built in 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small vessel of this type and period were engine/exhaust and machinery insulation, gaskets, valve packing, electrical insulation, and deck/accommodation materials. As a diesel craft she carried no boilers or steam turbines - the boiler/turbine lagging pathway of steam vessels does not apply, and her asbestos-relevant systems are the smaller diesel-era set in a compact 173-ft hull.
