- Finding
- An NHHC/DANFS-format narrative attributed to NHHC historians Raymond A. Mann and Robert J. Cressman is reproduced at seaforces.org: laid down 18 Nov 1972 at Newport News by Newport News Shipbuilding & Dry Dock Co.; launched 26 Apr 1975 (sponsor Mrs. F. Edward Hebert); commissioned 25 Jun 1977, Cmdr. Thomas C. Maloney; SubRon 1 then SubRon 8 (Jul 1979), Norfolk; post-shakedown overhaul at Newport News Shipbuilding 20 Feb-28 Aug 1978; 1980 Indian Ocean circumnavigation (Navy Unit Commendation); eighteen-month overhaul at Norfolk Naval Shipyard ending spring 1986 (AN/BQQ-5C sonar, CCS Mk-1 fire control, ESGN added); placed in reserve 1 Nov 1993; first Los Angeles-class boat decommissioned and stricken 13 Jan 1995; recycling complete 30 Sep 1997.

- Secondary reproduction of an NHHC-attributed narrative; the underlying official entry was not located on the live or archived NHHC site, so these particulars are leads pending primary confirmation, not findings. NVR independently confirms the milestone dates; the narrative particulars (sponsors, availabilities, squadrons) await the underlying NHHC entry, which was not located live or archived.

[3]New York Times, 'Pentagon Describes Damage To Sub After Arctic Collision' (1992-02-28); Los Angeles Times, 'U.S., Commonwealth Subs Collide Off Russia' (1992-02-19) - Pentagon/Navy statements [reputable_press]

- vessel_history
- Finding
- Collision with Russian Sierra-class submarine K-276 (later Kostroma): at periscope depth off the Kola Peninsula near Murmansk on 11 February 1992, Baton Rouge collided with the surfacing Russian boat; the Navy initially reported no damage, then disclosed two cuts plus dents and scrapes; the Navy reported 127 aboard and no injuries, and stated the boat was in international waters (>12 miles), a boundary Russia disputed. Baton Rouge returned to Norfolk unassisted and was removed from service within the year.

[4]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]

- GAO product page HRD-80-2 (full text blocked, HTTP 403)
- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s. Her 1972-75 construction and 1978-1993 availabilities (Newport News PSA, Norfolk NSY overhaul) sit inside the documented asbestos-use era and its early-1970s substitution transition.

- Finding type
- litigation_documented
- Finding
- Court-documented era regime: Navy thermal-insulation procurement specifications (32-I-3/MIL-I-2819 block and 32-P-8/MIL-I-2781 pipe insulation) required asbestos-containing thermal insulation in naval construction and repair; submarine insulation specs (SUBSAFE-era MIL-I-24244) covered submarine construction and overhaul. These regimes were in force during this hull's 1970s construction and service-era availabilities.

[6]Era inference built on: Naval Vessel Register build/availability milestones; shipyard-exposure-map documented asbestos product lists for newport-news-shipbuilding, norfolk-naval-shipyard (thermal insulation, submarine steam/propulsion lagging, gaskets, packing, block insulation) [other_primary]

- Finding type
- asbestos_application
- Finding
- Built 1972-75 at Newport News Shipbuilding with a post-shakedown overhaul there (1978) and an eighteen-month Norfolk Naval Shipyard overhaul (ending spring 1986), this hull's construction and repair events fall inside the documented asbestos era; era-standard applications on secondary steam/auxiliary systems (thermal insulation, gaskets, packing) are consistent but unverified.

- Population
- Builder-yard construction trades; Navy-yard availability trades; crew
- Limitations
- Class/era inference only - no hull-specific insulation survey or material list located. Names era-standard applications on secondary steam and auxiliary systems, not confirmed installed materials; the S6G reactor plant establishes nothing. This hull was built during the Navy's early-1970s asbestos-substitution transition, so original-asbestos inference is weaker than for 1950s-60s hulls and remains unverified either way. No quantity; current material condition undocumented.

- Finding type

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or qualifying asbestos case naming this hull was found. CourtListener API searches could not be run (125/day rate limit exhausted; reset ~15h) - Google-indexed CourtListener documents surfaced no document naming this hull as an exposure site; all surfaced hits were name collisions or unrelated litigation.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. A negative public-record search is not a materials survey; yard work-package and hazmat records, if they exist, are not public. CourtListener coverage was partial (API throttled; Google-indexed corpus only). Does not establish or defeat any claim of exposure or legal eligibility.
