Johnson in command; Pacific Fleet. Sailed from the west coast 5 February 1944; 5th Fleet air raids on the Palaus, Yap, Ulithi, and Woleai (30 March-1 April); Hollandia support (picket ship, tanker screen); escort-carrier screen for the Saipan/Tinian/Guam invasions June-August 1944 (helped splash three planes 17 June; escorted bomb-damaged Fanshaw Bay CVE-70 to Eniwetok); strikes on the Palaus, Mindanao, Luzon, and Central Philippines; Formosa/Okinawa pre-invasion neutralization (joined in downing several planes 14 October); Battle for Leyte Gulf; stood by torpedoed Reno CL-96 3 November; January 1945 strikes on Formosa, Luzon, Indo-China, Hong Kong, Nansei Shoto; Iwo Jima/Okinawa/Tokyo strikes; picket-boat kill 18 February; Parece Vela bombardment 3 March; Okinawa pre-invasion harassing fire 26 March and three months of fire support/screening (shared midget-submarine kill and three dive bombers). Radar picket station from 9 July 1945; on 28 July a biplane struck her starboard side, a bomb penetrated the after engine room, and she sank at 0235 with the loss of 47 of her crew. Spec block: Fletcher class; 2,050 tons; 376'6" x 39'8" x 17'9"; 36 kt; complement 320; 5 x 5", 10 x 21" tt, 6 dcp, 2 dct. Eight battle stars for World War II service.

- historical_record
- Finding
- Official postwar BuShips engineering analysis naming this hull: Table II lists CALLAGHAN (DD792) among destroyers lost by 'loss of buoyancy aggravated by radical trim' (Kamikaze, Okinawa, 7/29/45). Para 2-57 records that explosions 'occurred in the upper 5-inch handling room in CALLAGHAN (DD792).' Para 11-19 analyzes the loss as a close parallel to ABNER READ: 'A suicide plane with one bomb hit her in way of the after engineroom disrupting all power, light and water services aft and disabling the after repair party. A severe fire quickly engulfed the after end of the ship. After four minutes an explosion occurred in No. 3 upper handling room apparently due to a mass detonation of about 75 rounds of 5-inch projectiles, initiated by the roasting effect of the fire. CALLAGHAN immediately thereafter assumed a 15-degree starboard list but the fire subsided. About an hour and one half later the vessel plunged by the stern with a heavy starboard list.' Para 11-23 groups her among DD445-class losses attributable to conflagrations after loss of power/lighting/firemain to the after repair party - a design-vulnerability finding for the class.

- Finding
- Era/class inference: a Fletcher-class destroyer built February-August 1943 at Bethlehem Steel, San Pedro, with the class's uniform four-Babcock & Wilcox-boiler, two-shaft, 60,000-shp geared steam-turbine plant, would have carried the period-standard insulated fit - boiler and steam-line insulation, turbine lagging, gaskets and packing, fireproofing, bulkhead/compartment insulation, and deck coverings. The construction window sits squarely inside the Navy's documented peak asbestos-use era (GAO HRD-80-2: the Navy did not begin substituting asbestos-free materials until the early 1970s, decades after this hull sank). NARA RG 19 Bureau of Ships General Information Books, holding per-vessel material specifications, are the archival lead for hull-level confirmation.

[7]Atlas shipyard dataset (shipyards.json, 37 yard_ids): 'bethlehem-shipbuilding' record (tier 3, corporate-level, tagged Quincy MA; aliases Fore River/Sparrows Point/Union Iron Works) - Bethlehem Steel's San Pedro yard is NOT separately enumerated in the dataset [other_primary]

- Finding
- Builder-yard context with explicit limitation: the Atlas yard dataset carries a corporate 'bethlehem-shipbuilding' record documenting extensive era asbestos product use (85% magnesia block, Marinite, Transite, Unibestos, lagging, gaskets, packing, asbestos cement, cloth) - but its verified findings all concern Bethlehem's eastern facilities (Baltimore shipyard worker cohorts; Sparrows Point EPA Superfund/RCRA records). The builder of this hull - Bethlehem Steel Co., San Pedro (the former Los Angeles Shipbuilding & Dry Dock yard on Terminal Island) - is not separately enumerated in the 37-yard dataset, and no San-Pedro-yard asbestos documentation was located. Sibling-hull convention (uss-cassin-young-dd793, same builder) maps San Pedro-built Bethlehem hulls to the corporate 'bethlehem-shipbuilding' slug; carried identically here.

- litigation_documented
- Finding
- No qualifying asbestos litigation naming this hull was located; indeed no litigation of any kind naming this hull was located. Opinion index: zero hits for 'USS Callaghan', 'U.S.S. Callaghan', and 'DD-792'. The sole 'aboard the Callaghan' opinion hit is Vargas v. American Export Lines, Inc., 160 A.D.2d 223, 553 N.Y.S.2d 673 (N.Y. App. Div. 1990) - a verified name collision: the vessel is S.S. Admiral William Callaghan (a different ship under a different namesake) in a non-asbestos longshore personal-injury case (a lasher injured by a snapped turnbuckle in 1977; LHWCA/indemnity posture). RECAP docket index: zero hits for 'USS Callaghan' and 'DD792'; three dockets matched 'DD-792' - Hobley v. Wachovia Corp. (D.D.C. 1:06-cv-01739, pro se civil rights), Winn-Dixie Stores, Inc. ch. 11 (Bankr. M.D. Fla. 3:05-bk-03817, omnibus tax-claims order), and SIPC v. Bernard L. Madoff Investment Securities LLC (Bankr. S.D.N.Y., Adv. Pro. 10-05279) - in each the string appears inside document text as a claim, exhibit, or serial identifier, not as a vessel reference. Classification: no qualifying hits; all matches are name or identifier collisions.

- Limitations
- CourtListener indexes opinions and PACER dockets, not state trial filings, VA claims, asbestos trust claims, or settled/unreported matters - absence here does not prove no claim was ever filed. Sunk July 1945 with 47 lost; any survivor- or estate-era claim would be decades old and outside indexed coverage. 'Callaghan' is a common surname and a second naval Callaghan (DDG-994) served 1981-1998 - both screened as collision classes; neither produced a hit naming this hull. The 'DD-792' docket matches were not pulled for full text - their dockets are a pro se civil-rights action, a retailer's Chapter 11, and the Madoff SIPA liquidation, where the string sits inside document text (claim/exhibit/serial identifiers); vessel attribution is nonetheless possible only in the 'possible but unverified' sense noted here.
