- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track Navy records but the 24 January 1946 decommissioning conflicts with NavalCoverMuseum's 22 January 1946 (see gaps), and the April 1943 reclassification date is one month later than the 'SC 706' stamp already on the ship's 1 March 1943 war-diary page (see gaps). Contains no asbestos content. No photograph of this hull is on file in the archive.

- historical_record
- Finding
- Yard production table lists: 'SC-706 | US Navy | subchaser | 136 | 110 | 15 Oct 1942 | to the NDRF 1946' - corroborating the builder, the 15 October 1942 completion/delivery (the commissioning date), 110-foot length, and National Defense Reserve Fleet disposal in 1946. The same table documents her immediate sisters: SC-705 (delivered 2 Oct 1942, sold 1947 as Phyllis J) and SC-707 (delivered 24 Oct 1942, sold 1947 as Friendswood). Yard context: 'The Elizabeth City Shipyard was originally a division of the Elizabeth City Iron Works and Supply Company, formed in 1914 from the merger of the T. B. Hayman and E. S. Willey shipyards. It continued as a repair yard after the war but closed in the mid-1960s.'

- Secondary compilation of yard records, not a government registry; the table's '136' is a light-displacement-tonnage figure vs NavSource's 148 t. - likely different load conditions rather than a conflict, but unverified (see gaps). 'To the NDRF 1946' is consistent with Maritime Commission transfer 13 September 1946 (NavSource). Contains no asbestos content.

- Limitations
- Documents the ship's Argentia/Placentia Bay patrol duty March-May 1943 only - the catalog search surfaced no war-diary file units for this hull outside those three months, so service before March 1943 and after May 1943 is not covered by this series. The 'U.S.S. SC 706' stamp on the 1 March 1943 page predates NavSource's April 1943 reclassification date by one month - whether the stamp was applied contemporaneously or at monthly-diary compilation is unresolved (see gaps). Entries record routine harbor patrol, not operational detail; contains no asbestos or material content.

- Finding
- DANFS documents SC-706 as a convoy escort on the Norfolk-Caribbean-Canal Zone route in May 1944: 'A little over a half hour after the start of the afternoon watch on 16 May 1944, Zeus got underway in company with the internal combustion engine repair ship Oahu ..., and the submarine chaser SC-706, their escort. The ships joined convoy 435 ... reached Guantanamo Bay, Cuba, without incident at 1743 on 22 May, then sailed less than 24 hours later with convoy GZ-62, setting course for Panama.' Zeus arrived Cristobal, Canal Zone, 27 May 1944.

The Zeus entry prints 'Oahu (ARG-6)' - the hull number is omitted here as secondary sources carry Oahu as ARG-5; irrelevant to this vessel's record. Contains no asbestos content.

- Finding type

- Finding
- The ship's quarterly muster rolls survive for her entire commissioned life - 15 October 1942 through 24 January 1946 - digitized on the NARA catalog (208 images). Muster rolls list every enlisted man aboard at each quarter plus changes, making them the authoritative roster source for the ship's exposure-relevant population (approximately 28-man complement per NavSource specs). The file unit's own date range corroborates the 15 October 1942 commissioning and the 24 January 1946 decommissioning (NavSource variant) rather than the 22 January variant.

[7]Era inference built on: NavSource specifications (110-ft wooden SC-497 class; 2 x GM 8-268A diesels, no steam plant); shipbuildinghistory Elizabeth City production record (emergency wooden-craft yard, 1942); GAO HRD-80-2 Navy asbestos-use era documentation (see ev-07) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel submarine chaser built at a small emergency yard in 1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel patrol craft of this type and period were engine-exhaust and muffler lagging in the machinery space (heat protection in a wooden hull), machinery gaskets and valve packing, electrical insulation, and interior fireproofing/joiner board. As a diesel boat she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, and the material quantity aboard a 110-foot wooden craft, if present, would have been far smaller than aboard steam ships.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming PC-706 or SC-706 was found in the public sources searched (see search_ledger). CourtListener, all queries completed 2026-10-03: base queries SC-706 o=3,004 / r=20,233 and PC-706 o=3,336 / r=22,336 hits - every returned hit a court docket-number collision (Alabama SC-####-0706, Kentucky ##-SC-0706-xx, Indiana post-conviction ##-0706-PC-###, federal cv-00706 strings), no vessel or asbestos case. Asbestos-qualified variants (justified by the overflows): '"SC-706" asbestos' o=0, r=0; '"PC-706" asbestos' o=0, r=3 - all three r hits were document-content collisions inside other cases (W.R. Grace ch.11 service list; a generic NYCAL removal notice; Winn-Dixie service list), none naming the vessel. Litigation search closed: no qualifying case located.

- Absence of a located public record does not prove absence of asbestos aboard - era-consistent materials on a 1942 wooden diesel chaser remain a reasonable inference, not a ship-proven fact.

- Finding
- CORRECTION: the batch intake labeled this hull 'USS PC-706' with PC-461-class framing. The documented identity is a 110-foot wooden SC-497-class submarine chaser: commissioned under the temporary designation PC-706 on 15 October 1942 and reclassified SC-706 in April 1943 - the same pattern as her Elizabeth City sisters (SC-705 commissioned PC-705; SC-707 commissioned PC-707, reclassified SC-707 April 1943). She is not and never was a PC-461-class 173-foot steel patrol craft; 'PC-706' and 'SC-706' are one hull. Canonical designation: SC-706. The sisters' paths run parallel into civilian life too: SC-705 was sold 1947 as Phyllis J, and SC-707 was acquired in 1946 by the Humble Oil and Refining Co. and named Friendswood - the same buyer that took SC-706 as Sugarland (NavSource SC-707 page). Anomaly noted: the ship's own war-diary pages bear the 'U.S.S. SC 706' stamp as of 1 March 1943, one month before NavSource's April 1943 reclassification date - stamp timing vs. official reclassification unresolved (see gaps).
