- DANFS record for this hull: named for VADM Walden L. Ainsworth; construction contract awarded to Avondale Shipyards, Inc. 25 August 1966; laid down Westwego, La. 11 June 1971; launched 15 April 1972, sponsored by Mrs. Katharine Gardner Ainsworth; commissioned 31 March 1973 at Norfolk Naval Shipyard, Portsmouth, Va., Lt. Cmdr. Terrence E. Siple in command; Caribbean shakedown; post-shakedown overhaul Charleston Naval Shipyard Oct 1973 - Feb 1974; circumnavigated South America Jul-Dec 1974; reclassified FF-1090 30 June 1975; Mediterranean, Caribbean, Persian Gulf and Indian Ocean deployments 1975-1986 incl. 84 consecutive days underway during the Iran hostage crisis; first regular overhaul Philadelphia Naval Shipyard to 1 March 1979; restricted availabilities Norfolk Naval Shipyard 1980, Home Brothers' Shipyard Nov 1981 - Jan 1982, and Norfolk Shipbuilding & Drydock Co. 1986; overhaul Charleston Naval Shipyard Aug 1983 - Mar 1984 including sonar upgrade and CIWS installation; Beirut gunfire-support duty Jan 1983; assigned Naval Reserve Force Atlantic and redesignated FFT-1090 30 September 1990; decommissioned 27 May 1994 and leased to Turkey as TCG Ege (F-256); stricken 11 January 1995.

DANFS documents service history, not materials or asbestos content. First-CO rank discrepancy (DANFS 'Lt. Comdr.' vs NavSource 'Cmdr.') noted in gaps.

- Turkish government record confirms the hull's present status: TCG Ege (ex-USS Ainsworth) and TCG Pirireis opened to visitors at the Inciralti pier on 1 July 2007 as the Aegean region's first museum ships, operated as a 'first-class military museum' under Izmir Museum Ships Command / Turkish Naval Forces museum command; the district governorship states sections of TCG Ege were converted to exhibit/conference space while other sections were preserved in original condition. TCG Ege decommissioned from Turkish service 21 March 2005 (NavSource).

[5]GAO HRD-80-2, 'Navy Efforts to Protect Workers From Asbestos Exposure' (October 1979) - transmits Navy's 5 January 1979 statement and the October 1975 / January 1979 asbestos-insulation policies [gao]

- Finding type
- regulatory
- Finding
- Fleet program context for this hull's entire service life: GAO records the Navy's October 1975 policy of removing asbestos insulation only when damaged or when removal was required for repairs, modified January 1979 to selective replacement in high-maintenance areas; the Navy's January 1979 statement that all in-service ships contained some asbestos; and the Navy's rejection of a one-time fleet-wide removal program (~$2 billion estimated). This hull served 1973-1994 entirely within this policy regime; six documented U.S. yard periods during those years are the windows in which any ACM aboard would have been disturbed.

[7]DANFS/NavSource specifications block for the Knox class as listed for this hull + Atlas shipyards.json record 'avondale-shipyard' (tier-2 yard, documented asbestos litigation: Latiolais v. Huntington Ingalls, 5th Cir. 2019; Barrosse v. Huntington Ingalls, 5th Cir. 2023) [other_primary]

- Finding
- Era/class and builder-yard inference: a 1,200-psi steam plant (2 boilers, single Westinghouse geared turbine, single shaft per the class spec block) built at Avondale 1971-73 would have been insulated with period-standard asbestos products - boiler/casing insulation, steam-line lagging, gaskets, packing, and fireproofing - and builder Avondale is a tier-2 Atlas yard with documented asbestos litigation and products (Kaylo insulation, lagging cloth, gaskets, floor tile, adhesives, fire-resistant blankets). The hull's construction window straddles the Navy's ~1973 asbestos-free insulation specification change; whether delivered insulation was asbestos or substitute is unresolved.

- CourtListener sweep for this hull: no published opinion names USS Ainsworth ('"USS Ainsworth"' type=o = 0; '"FFT-1090"' type=o = 0). The single exact-name docket hit is Lasseigne v. 3M Co., 2:23-cv-00710 (D.S.C., filed 2023-02-21, terminated 2024-07-24, Judge R.M. Gergel) - a diversity product-liability complaint expressly captioned under MDL No. 2873 (master docket 2:18-mn-2873), the aqueous film-forming foam (AFFF/PFAS) MDL, not the MDL-875 asbestos MDL; classified OTHER LITIGATION (non-asbestos), the ship mention consistent with plaintiff service history. Hull-number sweeps produced only mechanical text collisions: '"DE-1090"' type=o = 7 hits, all docket-number/citation noise (e.g., '79-2738', F.2d pages); type=r = 41 hits, all docket-entry-number noise including the JPML MDL-875 master docket matching entry string 'DE-1090' inside attached ECF docket sheets - no ship-related result. '"FF-1090"' type=o = 0, type=r = 2 hits (both text collisions in unrelated dockets - debt-collection; PG&E bankruptcy exhibits); '"FFT-1090"' type=o = 0, type=r = 0; '"aboard USS Ainsworth" OR "aboard the Ainsworth"' type=o = 0. Widened query '"Ainsworth" asbestos "Knox" OR "FF-1090" OR "DE-1090"' type=o = 83 hits, all surname/place collisions - zero reference the ship. No qualifying asbestos litigation naming this hull was located.

All name/hull-number queries completed; only the tight '"TCG Ege"' opinion query remained unexecuted at close (6 paced retries exhausted under fleet-wide budget contention; the docket-cell counterpart returned 0) - a residual gap, not a finding. Name-collision guard applied: USNS Fred C. Ainsworth (T-AP-181) is a different vessel; no colliding hit surfaced. Absence of indexed litigation does not prove absence of exposure or claims.
