    NavSource record for this hull: PC-461 Class Submarine Chaser; laid down 13 January 1943 at Commercial Iron Works, Portland, Oregon; launched 12 February 1943; commissioned USS PC-787, 13 November 1943; transferred to the War Shipping Administration in June 1948; transferred to Indonesia in 1960 and named Alu Alu; fate unknown. Call sign November-Xray-Hotel-Alpha. Specifications: 450 t; 173'8" x 23' x 10'10"; 22 kts; complement 65; one 3"/50 dual purpose mount, one 40mm, three 20mm, two depth charge projectors, two depth charge tracks, two rocket launchers; two 2,880 bhp Hooven-Owen-Rentschler R-99DA diesel engines, Westinghouse reduction gear, two shafts. NavSource notes: 'There is no DANFS History currently available for PC-787'; sole photo is an Indonesian Navy image from the 1958/1959 edition of Jane's Fighting Ships (c. 1958).

    NavSource is a volunteer-compiled archive, not a government publication - but it is the standard citable index for hull-level dates on numbered craft with no DANFS entry. Page documents service history and specifications, not materials or asbestos content. Gives no decommission or stricken date, no wartime operating area, and no disposal detail beyond 'fate unknown'.

    Finding
    Ship-specific primary document placing this hull in the western Pacific at war's end: the ABSD-3 repair ledger lists 'P.C. #787' in the repair entry group dated 8-13-45 (13 August 1945) - the hull was drydocked/serviced aboard large auxiliary floating dry dock USS ABSD-3 at Guam, Mariana Islands, two days before V-J Day. The ledger itself spans 5 March 1945 through March 1946 repair dates at Guam; NavSource's ABSD-3 record confirms the dock was placed in service at Guam, Marianas Islands, circa 1944 and decommissioned 1 April 1946.

    Limitations
    A repair-ledger entry documents a drydocking event, not what work was performed, what materials were involved, or any asbestos content. The ledger gives no displacement/weight figure for this entry. Provenance is a NavSource-hosted scan of the handwritten dock record; date attribution relies on the column ditto-marks under the 8-13-45 group header.

    Finding
    Official-style Navy listing confirms this hull's existence and commission-era: PC-787 falls within the 'PC-783-798' group listed as commissioned 1942-44, with no notes of loss, naming, or reclassification. The PC-461 class block states: displacement 284 tons; length 173'8"; beam 23'; draft 10'10"; speed 21 knots; armament 1 3"/50, 1 40mm, 5 20mm, 2 depth charge throwers (mousetraps), 2 K-guns, 2 depth charge racks; complement 65; diesel engines, 2 screws, 2,280 shaft hp.

Class-block figures differ in detail from NavSource hull specs (displacement 284 t vs 450 t; armament 5 vs 3 20mm mounts; 2,280 shp vs 2,880 bhp engines) - variances carried in gaps, not reconciled.

Table documents the five ex-US PC-461 transfers to Indonesia in the 1958-1960 window (Tjakalang 10/1958; Tenggiri, Torani, Hiu, Alu Alu 3/1960) and Indonesian-service fit (SPS-10 and Decca 110 radars, QHA sonar; armament retained).

    Navypedia is a specialist secondary reference, not an official Indonesian or U.S. source - Indonesian commissioning and stricken dates rest on it alone and are carried as partial. Resolves NavSource's 'fate unknown' to 'stricken 1975' at secondary-source confidence only. Says nothing about materials or asbestos.

  6. [6]Era inference built on: NavSource PC-787 specifications (diesel plant, 1943 build); HyperWar PC-461 class block (284 t, diesel, 1942-44 commissions); GAO CED-78/HRD-80-2 context for Navy-wide asbestos-insulation era [other_primary]

    Finding type
    asbestos_application
    Finding
    Era inference: a PC-461-class submarine chaser built in 1943 under a wartime Navy contract at a commercial yard would have carried period-standard asbestos applications - diesel exhaust and machinery lagging, gaskets, valve and pump packing, electrical insulation, deck covering, and fireproofing in accommodation and machinery spaces. The diesel propulsion plant (two Hooven-Owen-Rentschler R-99DA diesels per NavSource) means no boiler/turbine lagging pathway as on steam vessels - the exposure-relevant systems are the engine-room exhaust/muffler lagging, piping and valve packing, electrical gear, and interior finishes typical of 1943 small combatants.

    Limitations
    Class/era inference only - no hull-specific insulation survey, material list, work package, or build specification document located for PC-787. Names era-standard applications, not confirmed installed materials. No quantity. Engine make varies across references (Hooven-Owen-Rentschler per NavSource; General Motors per navypedia) - see gaps. Commercial Iron Works is not in the Atlas shipyard dataset, so no yard-level asbestos documentation applies.

    cl-auth-search.py results: "PC-787" type=o (1 hit, collision); "PC 787" type=o (1 hit, same collision); "PC 787" type=r (19 hits, all collisions); "PC-787" type=r (blocked, 9 attempts)

    litigation_documented
    Finding
    No qualifying asbestos litigation naming this hull located in CourtListener. Three of four mandated base queries completed: "PC-787" opinion search returned 1 hit (John Deckard v. State of Indiana, Ind. Ct. App. 2015 - a post-conviction matter whose appellate docket number 53A01-1405-PC-222 contains the string 'PC', a name collision, not the vessel); "PC 787" opinion search returned the same single hit; "PC 787" docket search returned 19 hits, all string collisions (bankruptcy and civil dockets containing 'PC 787' in unrelated contexts - e.g., In re Dana Corp., Xarelto MDL, Medeiros v. Springdale Borough; none naming a vessel). The fourth base query ("PC-787" docket search) could not be completed: the fleet-wide pacing budget refused the request across repeated spaced attempts (5+) over ~2.5 hours - logged as blocked, not a negative result. Given the completed queries returned zero qualifying hits on a zero-collision hull number, the litigation gap is narrow but real.

    Limitations
    The unrun docket query ("PC-787" exact) could theoretically surface RECAP filings tokenized differently than the completed 'PC 787' search; residual gap disclosed. No ship, court, or plaintiff was found in the completed hits - nothing here establishes or defeats any claim of exposure or legal eligibility. Name-match hits were classified as collisions, not vessel references.

    Finding
    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, material list, hazmat disclosure, museum record, or docketed case naming USS PC-787 (or KRI Alu-Alu) was found in the public sources searched. No DANFS entry exists for this hull (NavSource confirms). No MARAD vessel status card exists for this hull (verified against a database that indexes sibling PCs). The only 'asbestos aboard' material surfacing in secondary web results is generic law-firm marketing content asserting asbestos aboard patrol craft without primary sourcing - excluded by source policy.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - a 1943 wartime commercial build almost certainly carried era-standard ACM, which is why the class/era inference row exists. NARA deck logs, war diaries, BuShips work packages, and Commercial Iron Works contract records are undigitized leads. One of four CourtListener base queries remains unrun (blocked) - see ev-06.
