    vessel_history
    Finding
    The chronology sheet identifies NAJADEN as Daphne class, hull/pennant P 534, built at Orlogsværftet (NB 204), laid down 20 September 1961, launched 20 June 1962, entered service 26 April 1963, and retired 1 October 1991. It also identifies the U.S. designation PGM-49 and states that the vessel was built under MDAP.

    Orlogsværftet construction trades (1961-1963); Royal Danish Navy crew (1963-1991)
    Limitations
    A specialist naval-history reference archive rather than a current Danish government registry; it documents identity and service chronology, not asbestos content, exposure, or legal eligibility. The sheet does not state a disposal location or final fate.

    Finding type

    Finding
    The 1982 Danish fleet list places P 534 Najaden in the Daphne-class patrol-vessel group and gives the class data as approximately 37 m length, 6.8 m beam, 2.6 m draught, 180 tons displacement, and 20 knots; the armament line identifies a 40 mm gun, depth charges, and mines for the group.

    Limitations
    The fleet list is a period class/fleet reference and does not provide a hull-specific machinery survey, crew record, asbestos inventory, or exposure finding. Class figures are not treated as proof of material aboard this hull.

    GAO product page HRD-80-2
    Finding type
    gov_survey
    Finding
    GAO documents the U.S. Navy's program-level asbestos-protection and insulation-removal concerns during the period after Najaden was built and while it served. This provides general naval asbestos-era context only.

    Population
    U.S. Navy program and shipyard workers; not Najaden personnel
    Limitations
    The report concerns U.S. Navy policy and does not cover the Royal Danish Navy, Orlogsværftet, MDAP construction of PGM-49, or this hull. It cannot establish that asbestos was installed aboard Najaden, cannot identify products or quantities, and cannot establish exposure or legal eligibility. Product page was accessible; full report text was not retrieved in this session.

    Finding type
    historical_record
    Finding
    No ship-specific asbestos survey, abatement contract, hazmat disclosure, government inspection, or qualifying asbestos-litigation record for PGM-49 / P 534 Najaden was located in the public sources searched. The available ship records document identity, service, and general specifications but do not mention asbestos.

    Study period

    Limitations
    A negative public-source result does not prove that asbestos was absent; it establishes only that no qualifying public documentation was located. CourtListener work was incomplete because the authenticated fleet limiter reported its paced budget momentarily spent after the first attempted base query; no asbestos-qualified variants were run. Danish naval archives, yard records, disposal records, and any non-indexed litigation remain gaps.
