[2]GAO HRD-80-2, 'Navy Efforts to Protect Workers from Asbestos Exposure' (5 Oct 1979), Enclosure I, Attachment #1 (Encl. (1) to CNO Ser 4542/318054 of 5 Jan 1979), 'List of U.S. Navy Ships Delivered Since 1973 or Under Construction' - FFG table, row 'DUNCAN / 10 / start 2/77 / del. 3/80' [gao]

- Finding
- A Department of the Navy list furnished to GAO (Encl. 1 to CNO Ser 4542/318054 of 5 Jan 1979) names this hull - 'DUNCAN', hull no. 10, construction start 2/77, projected delivery 3/80 - in the 'GUIDED MISSILE FRIGATE - FFG' block (FFG-7 OLIVER HAZARD PERRY through FFG-22/23 Unchristened). The THERMAL INSULATION column for that block carries the annotation 'Asbestos-free thermal insulation', vertically centered on the FFG block per the table's own convention (the same layout marks 'Asbestos thermal insulation' centered on the FF-1090-1097 block and splits the DD-963 block into asbestos / asbestos-free sections at DD-973/974). The document therefore represents Duncan's thermal insulation for machinery, equipment, and piping as asbestos-free.

- Population
- USS Duncan crew 1980-1994 (complement 174 per DANFS); Todd Pacific Seattle construction trades 1977-1980; Navy Reserve and IMA personnel during availabilities
- Limitations
- Scope is thermal insulation only (machinery, equipment, piping per Note 1). Note 1 states asbestos remained in 'shipboard applications for which no suitable (asbestos-free) substitutes have as yet been designated, i.e., gaskets and pipe hanger liners' - a fleet-level statement, not a hull inventory. The annotation is a block-level mark across FFG-7 to FFG-22/23 read by the table's internal layout convention, not a per-hull unique line; a misreading of that convention cannot be excluded, though the centered-position pattern repeats on every block of the attachment. The list is dated 5 Jan 1979 while Duncan was still under construction (projected delivery 3/80; actual commissioning May 1980); it does not address post-delivery alterations, availabilities, or the 1999-2017 Turkish-custody period. gao.gov blocks automated fetches (HTTP 403); verification performed against the Wayback-captured PDF - page images rendered and read.

[3]GAO HRD-80-2, 'Navy Efforts to Protect Workers from Asbestos Exposure' (5 Oct 1979), report body - Navy asbestos-transition narrative [gao]

- GAO HRD-80-2 body, 'Navy's Policy on Use of Asbestos' section and Q&A on insulation quantities (report pp. 2-5 of the letter/enclosure pagination)
- Finding type
- regulatory
- Finding
- GAO documents the Navy's asbestos phase-out during Duncan's construction window: thermal-insulation product specifications were changed in 1973 to asbestos-free materials; the Navy's policy to eliminate asbestos where substitutes were designated was issued October 1975; nevertheless 'asbestos materials had already been purchased and in some cases installed in ships under construction. Therefore, some ships were delivered with asbestos insulation as late as May 1978.' The report adds that '[e]ach ship has several types of asbestos containing materials installed,' that 'all ships presently in service contain some quantity of asbestos,' and that substitution required per-shipyard contract modifications (early successes cited: CVN-68 class 1971, last two SSN-637s 1972; the first eleven DD-963s changed later).

Duncan's ship-specific thermal-insulation status is separately addressed by the document's own Attachment 1 (ev-uss-duncan-ffg10-01). The 'all ships in service' observation applied to ships already delivered in 1979; Duncan was still building. gao.gov blocks automated fetches; verified via Wayback capture.

Barker in command, assigned Destroyer Squadron 1 at Long Beach; 21 Jan 1984 assigned to Naval Reserve Force, Long Beach - 'the first FFG assigned to NRT duty'; 17 Dec 1994 decommissioned after 14 years 7 months, 'first Perry Class frigate to be decommissioned'; struck 5 Jan 1998; '04 May 1999: Sold to Turkey as a parts hulk for cannibalization of spare parts.' Official photo captions place the hull at Hobart, Tasmania (June 1982), RIMPAC '88 at Pearl Harbor (1 Jul 1988), Vancouver port visit (27 Jul-1 Aug 1988), PACEX '89 (29 Sep 1989), DesRonOne NRF formation off San Clemente Island (23 Jan 1994), and moored at the Ships Intermediate Maintenance Facility middle loch, Pearl Harbor (31 May 1996); then the Bosphorus tow 22 Mar 2017 and sinking 4 Oct 2017. First-CO tenure listed 24 May 1980-28 Jun 1982 (Barker) - consistent with DANFS's 24 May commissioning, in tension with the page's own '15 May 1980' line.

- Documented end-state of this hull under Turkish custody: bought from the U.S. Navy as a spare-parts source for the eight in-service Gabya-class (ex-Oliver Hazard Perry) frigates - cannibalization, never commissioned into Turkish service and never given a Turkish name. The stripped hull was towed through Istanbul toward the Black Sea on 22 March 2017 by Turkish Navy tugs TCG Inebolu, TCG Ozgur, and TCG Darica; it survived the Deniz Yildizi exercise (29 Mar-9 Apr 2017) and, per the Turkish Navy, was sunk in the Black Sea on 4 October 2017 by a Mk-24 Mod. 2 Tigerfish torpedo fired from the submarine TCG Sakarya (S-353).

THE MOST PREVALENT CRACKING OCCURS AT FRAME 200.5'; SHIPALT FFG 7-146K imposed stringent QA and aluminum-welding procedures; an accompanying alteration required permanent removal of PCMS coating material and non-skid from critical weld areas for inspection. Contextualizes secondary-source reporting that Duncan developed a 40-ft superstructure fissure in heavy weather in December 1982 and underwent repair in early 1983 - a documented class-level structural condition that generated repeated yard repair periods across the class.

- Class-level document that does not name FFG-10; issued April 1996, after Duncan's December 1994 decommissioning - the SHIPALT-146K program may never have been applied to this hull. The advisory concerns aluminum welding and coatings, and does not mention asbestos; it is carried only as context for the class's repair history. Duncan's December 1982 crack itself is sourced to secondary literature (Daniels, 'The End of an Era,' 2004; RINA Transactions vol. 131, 1989) - no primary record located.

- Yard-level context only: the Atlas shipyards dataset carries the builder (Todd Shipyards Corp.) as a tier-2 yard with documented asbestos-era litigation - Washington Supreme Court record of a subcontractor worker at Todd's Seattle-area sites (1960s-early 1970s) who developed pleural thickening, asbestosis, and fatal mesothelioma. Establishes that asbestos products were present and litigated in the same yard complex where Duncan was built a few years later; it does not establish that Duncan herself contained asbestos beyond the 1979 Navy listing's terms.
