- Finding
- Official DANFS record for this hull: launched 4 July 1944 by Federal Shipbuilding & Drydock Co., Newark, N.J.; commissioned 27 January 1945; after WWII escort, patrol, air-sea-rescue, and weather-reporting duties, decommissioned at San Diego 31 May 1946; recommissioned 27 December 1950; served with Escort Squadron 9 and Task Force 95 off Korea; decommissioned at Mare Island 11 December 1959. DANFS identifies Hanna as John C. Butler class, 1,350 tons, 306 ft, 24 knots, complement 186, and records five Korean-service stars.

- historical_record
- Finding
- NHHC's chronology records ship-specific Korean-War events: USS Pelican (AMS-32) collided with USS Hanna (DE-449) on 21 November 1952, causing minor material damage to both ships; on 24 November 1952 Hanna received 50 rounds of estimated 105-mm shore fire near Songjin, with one hit damaging an evaporator and killing one man.

[5]Owens-Illinois, Inc., Industrial Health Survey of Federal Shipbuilding and Dry Dock Co., Kearny, N.J. (30 August-2 September 1944); Atlas shipyard dataset record federal-shipbuilding-kearny [other_primary]

- Finding type
- asbestos_application
- Finding
- Builder-yard evidence: a 1944 industrial-health survey at Federal Shipbuilding & Drydock documented insulators cutting and fitting Johns-Manville Superex asbestos pipe covering and boiler insulation in confined shipyard spaces. The survey occurred while Hanna was in late construction, after her 4 July 1944 launch and before her 27 January 1945 commissioning.

- Limitations
- Yard-level and era evidence only: the survey does not name Hanna, identify an installation aboard DE-449, quantify any material aboard, or establish individual exposure. It documents products and work at the builder's yard, not this hull's material inventory.

- Finding type
- historical_record
- Finding
- Archival lead: Hanna's operational periods fall within NARA's RG 24 deck-log series. Deck logs could document dates, locations, collisions, damage, and yard availability, but they are not a substitute for a material inventory; no Hanna log or hull-specific work package was retrieved in this session.

[7]CourtListener API v4 litigation sweep, authenticated fleet-paced helper: exact-name query USS Hanna and hull-number query DE-449 [court_record]
- Locator
- Authenticated helper output: USS Hanna opinion type=o count 0; USS Hanna RECAP type=r count 0; DE-449 type=o and type=r stopped by fleet pacing
- Finding type
- litigation_documented
- Finding
- Authenticated CourtListener exact-name sweep: both the opinion and RECAP-docket searches for 'USS Hanna' returned zero results. The required hull-number opinion and docket searches for 'DE-449' were halted by the fleet-pacing stand-down before results. Thus no qualifying asbestos litigation was located in the completed exact-name indexes, but hull-number coverage remains unresolved.

- Limitations
- Partial negative finding only. Zero exact-name index results do not prove that no case exists, and the incomplete hull-number queries prevent a complete sweep. The helper reported the fleet-wide request budget momentarily spent and directed no retry loop. PACER full text and state-court filings are outside CourtListener-index coverage.

- Limitations
- A negative public-record search does not prove that asbestos was absent from Hanna or that no exposure occurred. CourtListener coverage is incomplete because fleet pacing prevented results for both required hull-number queries; exact-name indexes returned zero results. See ev-06 and the search ledger.
