- NavSource record for sister ship PCE-1608 / HRNLMS Panter (F 821), built at the same Avondale Marine Ways yard, laid down 3 August 1952, launched 1 May 1954, and delivered/commissioned 11 June 1954 - the same delivery date documented for Jaguar - independently corroborates Avondale as the builder and 11 June 1954 as the MDAP transfer/delivery date for this pair of hulls.

- en.wikipedia.org Roofdier-class frigate, ship list table and class-index table
- Finding type
- historical_record
- Finding
- Wikipedia's Roofdier-class frigate article tabulates Jaguar (PCE-1609/F 822) as built by 'General Shipbuilding & Engineering Works' (Boston), conflicting with the Avondale Marine Ways (New Orleans) attribution given by both NavSource (ev-01) and Seaforces (ev-02). The same article's separate class-index table scrambles pennant-to-hull-number pairings inconsistently with both single-ship sources. Not used as a citation for builder; recorded here only to document the conflict and why it is resolved in favor of the two independent ship-specific sources.

- Finding type
- historical_record
- Finding
- Search of the NHHC Dictionary of American Naval Fighting Ships (DANFS) index located no entry for PCE-1609 or for any 'Jaguar' hull corresponding to this vessel. The only DANFS entry under 'Jaguar' is the unrelated USS Jaguar (IX-120), an Armadillo-class tanker/floating storage ship commissioned 15 December 1943 and decommissioned 10 June 1946 - a different, previously-existing hull with no connection to PCE-1609. This negative result is consistent with PCE-1609 having been built for direct MDAP transfer and never placed in commission in the U.S. Navy.

- Confirms absence of a DANFS record for this hull and rules out a name-collision misattribution (USS Jaguar IX-120 is a different ship). Does not and cannot speak to asbestos content - it establishes only that no USN commissioning history exists to document.

- 817 F.3d 457, background/history section reciting Avondale's federal-contract shipbuilding history 1952-1976; full-text verified via web search extraction of the published opinion text (CourtListener API access to confirm the opinion ID was blocked by fleet-wide rate-limit contention this session - see search_ledger sl-06; citation verified by exact quoted text and official reporter citation, not by CourtListener lookup)
- Finding type
- asbestos_application
- Finding
- Published Fifth Circuit opinion, Savoie v. Huntington Ingalls, Inc., 817 F.3d 457 (5th Cir. 2016), recites: 'From 1952 through 1976, the great majority of ocean-going vessels built at Avondale Shipyard in Louisiana fulfilled contracts from the federal government,' and that 'the specifications for these Navy and Coast Guard vessels required asbestos insulation through at least 1968.' This hull (PCE-1609) was laid down 10 December 1952 and launched 20 March 1954 at Avondale Marine Ways - squarely inside the 1952-1976 federal-contract window the opinion describes, and within the pre-1968 period in which the opinion states asbestos insulation was specified for Navy and Coast Guard vessels built there.

- Population
- Avondale Marine Ways shipyard construction trades, federal Navy/Coast Guard contract vessels, 1952-1968
- Limitations
- Builder/era-level finding only - the opinion describes Avondale's federal-contract specifications generally and does not name PCE-1609, Jaguar, or any Roofdier-class hull. It establishes that asbestos insulation was a specification requirement for federal Navy/Coast Guard vessels built at this yard during this hull's construction window, not that asbestos was installed aboard this specific hull, in what quantity, or where. The opinion itself concerns a later Avondale successor-liability dispute, not this vessel.
