- Finding
- The Navy's DANFS entry identifies Isherwood as DD-284, Clemson class, with a stated complement of 120. It reports launch by Bethlehem Shipbuilding Corp. at Squantum, Massachusetts, on 10 September 1919 (sponsor Mrs. R. C. Walling), commissioning on 4 December 1919 at the Boston Navy Yard under Lt. Comdr. W. D. Brereton, decommissioning at Philadelphia on 1 May 1930, sale on 17 January 1931, and scrapping by the purchasers in 1934. The entry describes: shakedown with the 43d Division, 1st Squadron, Destroyer Force, Atlantic Fleet; Guantanamo Bay operations February-April 1920; escorting Pennsylvania for the Secretary of the Navy at Lynnhaven Roads; Mexican coast patrol to June 1920; Charleston reserve status from October 1920; reactivation at 50 percent complement May 1921; Naval Reserve transport and target practice; Boston Navy Yard repairs 13 March-8 May 1922; Destroyer Squadron 9 exercises out of Yorktown; Caribbean, Beaufort, and Baltimore operations to March 1925; a May 1925 Naval Reserve cruise from Maine to the District of Columbia; Caribbean maneuvers from September 1925; departure for France 12 June 1926 with a goodwill cruise to British and Mediterranean ports; return to Boston 15 July 1927; reservist training cruises and Caribbean maneuvers to June 1929; and a 1929 summer reservist cruise from Jacksonville. Kalmia (AT-23) towed her from Norfolk to the Philadelphia Navy Yard on 26 August 1929, where she decommissioned.

- Bethlehem Squantum construction trades 1919; USS Isherwood crew 1919-1930 (design complement 120)
- Limitations
- DANFS documents identity and service history; it does not identify asbestos, installed insulation, equipment brands, individual exposure, or a crew roster, and it does not state laid-down or stricken dates. The cited text is a 2004 Wayback capture of the official history.navy.mil page because the current NHHC DANFS Isherwood URL returns HTTP 404. The complement is a specification, not an actual muster count.

- Finding type

- Finding
- NARA Special List 44 indexes Isherwood Navy logbooks from 4 December 1919 through 1 May 1930, independently corroborating the ship and its commissioned-service endpoints. A separate index row lists Isherwood (DD-520) logbooks 12 April 1943 to 30 June 1945; that row belongs to the later Fletcher-class namesake and is not attributed to DD-284.

- Finding type

- Finding
- NARA's Ship Plan Index lists ISHERWOOD DD-284 under RG 19 Alphabetical Ship Drawings (NAID 175669464) and Microfilm of Ship Engineering Drawings (NAID 175669464). These are leads for hull-specific material research; the drawings have not been retrieved. The same index lists ISHERWOOD DD-520 under Hull series of Ship Engineering Drawings (NAID 153714547); that entry belongs to the Fletcher-class namesake and is not attributed to DD-284.

- Finding
- The Thomas Crane Public Library (Quincy, Mass.) Fore River Shipyard Postcard Collection catalogs a photographic postcard of this hull with the caption data 'USS Isherwood, destroyer; built at Squantum Victory Yard; keel laid 5/24/1919, launched 9/10/1919, delivered 11/26/1919, scrapped 1934.' The record corroborates the builder (the Squantum yard was a Bethlehem Shipbuilding plant adjoining Fore River) and the DANFS launch date, and supplies keel-laid and delivery dates that the consulted DANFS entry does not state.

- Finding type
- asbestos_application
- Finding
- A published federal trial opinion documents that U.S. Government ship construction, conversion, and repair specifications were incorporated into supply contracts, prohibited deviation, and 'required that asbestos be used in the materials Johns-Manville supplied' for Government ships; the companion trial findings describe Navy asbestos insulation products including '85 percent Magnesia' pipe covering (approximately 85 percent magnesium carbonate and 15 percent asbestos fiber), asbestos cement, asbestos cloth, and marine bulkhead panels applied in engine and boiler rooms. This documents Navy asbestos-product specifications as a class-of-service-era fact; the retrieved product findings principally address World War II procurement, after this hull's 1934 scrapping.

- Limitations
- The trial decision was vacated on jurisdictional grounds, so its findings are a historical account of documents discussed at trial, not an affirmed merits judgment; the 12 Cl. Ct. 'required' statement recites complaint allegations. The retrieved excerpts center on WWII-era procurement - whether the described specifications were in force during this hull's 1919 construction and 1919-1930 service is not established by the retrieved text (the full 93-page trial opinion was not retrievable this session). The opinion does not name Isherwood or identify her suppliers, machinery, repairs, or crew tasks. A Government specification does not show purchase or installation on this hull.

- litigation_documented
- Finding
- No qualifying ship-specific asbestos documentation or litigation naming USS Isherwood (DD-284) was located in the public sources searched and recorded in the search ledger. Non-vessel hits exist for the name: Isherwood v. Newport News Shipbuilding & Dry Dock Co., 289 F. 282 (E.D. Va. 1922) is a patent-license suit by a person named Isherwood (the 'Isherwood system' of ship construction), not the ship; and asbestos-litigation marketing pages naming 'USS Isherwood' predominantly reference DD-520, the 1943 Fletcher-class namesake.

- A negative search result is limited to the named public indexes and queries actually completed; see the search ledger for which CourtListener queries completed and which remained pending under fleet pacing. It does not prove the ship lacked asbestos, that an unindexed case does not exist, or that any person was or was not exposed. NARA's underlying DD-284 plans and General Information Books were not inspected.
