- Finding
- DANFS record for this hull: named for Chief Machinist's Mate Daniel William Carlson, USN (b. 17 April 1899, Virginia, Minn.; enlisted 1 July 1920; CMM 5 July 1935), killed aboard Hammann (DD-412) when torpedoed in the Battle of Midway 6 June 1942, posthumous Silver Star. Spec block: dp. 1,140; l. 289'5"; b. 35'1"; dr. 8'3"; s. 21 k.; cpl. 156; cl. Evarts. Originally scheduled for transfer to Britain as BDE-9; sponsored by Mrs. D. W. Carlson; commissioned 10 May 1943, Lt. H. E. Purdy, USNR. Norfolk departure 23 July 1943, Espiritu Santo arrival 31 August; 7 months Guadalcanal/northern Solomons convoy escort and antisubmarine patrol; San Francisco overhaul May 1944; Hawaiian-area submarine training, target ship and plane guard June-September 1944; Eniwetok-Ulithi tanker-convoy escort from 6 October 1944 supporting Philippines and Iwo Jima operations to 21 March 1945; Leyte, then Southern Attack Force screen for the Okinawa assault 1 April 1945; Saipan reinforcement run 6-17 April; screening station Okinawa-Kerama Retto (torpedo passed under bow; planes driven off); cleared Okinawa 29 June 1945; Leyte, TF 38 replenishment-group screen through end of war; departed for San Pedro 16 September; decommissioned 10 December 1945; sold 17 October 1946. Two battle stars for WWII service.

- DANFS documents service history and specifications, not materials or asbestos content. DANFS reads 'launched 10 May 1943 ... and commissioned 10 May 1943' - a same-day launch/commission that is internally inconsistent; NavSource, uboat.net, navypedia, and NavalCoverMuseum document launch on 9 January 1943 (carried; conflict in gaps). DANFS spec block gives cpl. 156 and 21 k; class compilations differ (gaps). Live page verified 2026-09-29 via browser-UA fetch; default-UA requests receive HTTP 404.

- Finding
- The ship's own end-of-war history letter corroborates and extends DANFS with contemporaneous operational detail: commissioned 10 May 1943 at Boston Navy Yard under Lt. Comdr. Howard E. Purdy (Roselle Park, N.J.); shakedown at Bermuda, June 1943 Boston post-shakedown repairs; Panama Canal early August; Pago Pago Harbor, Tutuila, 23 August; departed escorting SS Rheem and two other merchantmen - a week later Rheem was torpedoed off Espiritu Santo but made port, and Carlson ran hunter-killer operations with negative results; escort duty through the South Pacific and ASW screen off Guadalcanal; Stapleton relieved Purdy 25 October 1943; convoys to Rendova, Munda, Bougainville, Treasury Island 24 January-10 February 1944 (consolidation of the northern Solomons); departed Guadalcanal 10 April 1944 escorting 12 LSTs to Pearl Harbor; then independently to Treasure Island, California, for overhaul (the yard behind DANFS's 'San Francisco'), completed 2 June 1944; departed San Francisco with USS Seid (DE-256) for post-overhaul repairs at the Pearl Harbor Navy Yard; SubTraPac/ComAirPac target-ship and plane-guard duty from 14 June; departed Pearl 25 September 1944; Eniwetok-Ulithi escort duty in TG 10.14 from 19 October - fast-tanker convoys fueling the Third and Seventh Fleets; detached 21 March 1945 for Leyte with USS Santee and USS Lavaca; Southern Attack Force screen (Rear Admiral J. L. Hall; flagship with Vice Admiral Turner in the unit); off Okinawa for the 1 April assault - depth-charged a possible submarine, screening by day and transport guard by night; Saipan run 6-17 April; Okinawa-Kerama Retto screening station where a torpedo passed under her bow and planes were driven off on three occasions; departed 30 April for sonar repairs at Saipan; Loewith relieved Stapleton 6 May 1945; final Okinawa tour 27 May-28 June; departed 29 June with 16 LSTs to Leyte; assigned TU 30.8 replenishment group (Rear Admiral Beary) supporting TF 38's bombardment of Japan; Ulithi detachment 23-27 July with four oilers; escorted two CVEs to Eniwetok 1-9 August; rejoined TU 30.8 via Guam 23 August; designated to the Tokyo occupation force, then detached with USS Alcyone for Guam as TU 30.8 sailed for Sagami Wan; departed Guam 16 September via Pearl Harbor (arrived 25 September) for San Pedro decommissioning (tentative date then 7 December; actual 10 December 1945).

- Primary ship-generated document (signed cover letter + 3-page typed enclosure, 6 December 1945, received S-C Files 12 December 1945) - strongest available service record for this hull; contains no materials or asbestos information. Scan hosted on NavSource (secondary repository) - the document itself is the ship's submission, transcription read directly from the scan. Dates for CO reliefs differ from NavSource's secondary roster (conflict in gaps); two vessel names transcribed with care from the scan (Santee, Lavaca, Alcyone, Seid all legible).

- Locator
- navypedia us_de_gmt.htm member table (DE-9 row) + technical data block; NavSource DE-9 specifications block
- Finding type
- asbestos_application
- Finding
- Era/design inference: the Evarts class is the 'GMT' (General Motors Tandem) short-hull diesel-electric DE - four GM Model 16-278A diesel engines driving electric motors, two shafts, ~6,000 hp (navypedia class technical data: 4 GM diesel-generators + 2 electric motors, 6,000 hp, 19.5 kt, 6,000 nm at 12 kt; member table lists DE-9 built at Boston N Yd, Charlestown, laid 11/1942, launched 9.1.1943, stricken 1.1946). A 1942-43 USN warship of this plant type would have carried era-standard asbestos-containing materials appropriate to a diesel-electric escort - engine and exhaust insulation, machinery gaskets and packing, electrical insulation, fireproofing/joiner materials, and deck coverings - rather than the boiler, turbine, and steam-line lagging of steam-propelled warships.

- Population
- Boston Navy Yard construction trades 1942-43; crew 1943-45
- Limitations
- Class/era inference only - NOT a hull-specific finding. The diesel-electric plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply; no ship-specific material schedule, insulation specification, or asbestos survey exists for DE-9. Establishes no quantities and no exposure for any individual.

- asbestos_application
- Finding
- Builder/repair-yard context: the hull was built at Boston Navy Yard, Charlestown (Atlas yard record 'boston-naval-shipyard', tier 3, with documented asbestos product identification in litigation), and the ship's own war history documents post-overhaul repairs at the Pearl Harbor Navy Yard in June 1944 (Atlas yard record 'pearl-harbor-naval-shipyard', tier 1, with an extensive documented asbestos product list and a peer-reviewed mesothelioma cohort). Yard-level documentation establishes asbestos-era materials in the yards that built and repaired this hull - not materials installed aboard DE-9 itself.

The May-June 1944 overhaul site (Treasure Island, San Francisco) is absent from the yard dataset.

[7]CourtListener API v4 litigation sweep for 'USS Carlson' / 'Carlson' 'DE-9' / 'Carlson' asbestos destroyer (type=o opinion index and type=r RECAP dockets), via authenticated fleet helper [court_record]

- Finding
- CourtListener sweep located no qualifying asbestos litigation naming this hull. Opinion index (type=o): exact-phrase 'USS Carlson' returned 0 hits; 'Carlson' 'DE-9' returned 6 hits - all name collisions ([DE 9] docket-entry notation and unrelated Carlson surnames in Puerto Rico mortgage matters, a Texas insurance appeal, a Kentucky civil-rights case, and a Puerto Rico criminal matter - none vessel-related, none asbestos); 'Carlson' asbestos destroyer returned 0 hits. RECAP docket index (type=r): exact-phrase 'USS Carlson' returned 0 hits. A combined variant docket query could not be completed - the fleet-wide request budget stayed spent across spaced retries; logged as blocked, not as negative.

- Limitations
- Sweep covers the opinion index (exact name, hull-number co-occurrence, and asbestos-context queries all completed) and the RECAP docket index for the exact phrase; broader variant docket queries remain unsearched. A litigation index is not exhaustive: unindexed pleadings, state-court filings, MDL-875 complaint text, and sealed/settled matters remain outside this result; absence of a located case does not prove no suit ever named the vessel.

- Finding
- No qualifying ship-specific asbestos record located for DE-9: no hull ACM survey or abatement disclosure exists in public sources (hull sold for scrap in late 1946 - nearly three decades before the Navy's formal asbestos-management era; no museum custodian to publish restoration disclosures), the ship-submitted war history and DANFS contain no materials information, and the CourtListener sweep located no asbestos case naming this vessel (see ev-06). The ship appears on law-firm asbestos marketing ship lists - excluded per source rules and carried as context only.
