USS Hassayampa (AO-145) was a Neosho-class fleet oiler that served the U.S. Navy from her commissioning on 19 April 1955 through decommissioning on 31 March 1991. Built by New York Shipbuilding Corporation, she provided underway fuel replenishment to Pacific Fleet operations across 36 years of service — including Vietnam War combat operations, where fleet oilers were essential for sustained carrier strike-group operations.
The 60-entry equipment manifest below is one of the most complete BUSHIPS-sourced documentation sets available for a Neosho-class ship. Each entry represents documented machinery with verified manufacturer attribution — primary-source evidence for asbestos exposure-claim development.

Asbestos Exposure Aboard Hassayampa
Hassayampa’s machinery plant — Babcock & Wilcox main boilers with Copes-Vulcan regulators, Westinghouse main turbines and Sturtevant-division forced-draft blowers, Foster-Wheeler condensers throughout, ITE switchboards — was constructed using extensive asbestos-containing materials:
- Pipe lagging and thermal insulation wrapping steam, feed-water, fuel-oil, cargo-oil, and condensate piping throughout machinery and cargo spaces
- Boiler block insulation, refractory brick, and gun-blocks around the Babcock & Wilcox boilers
- Asbestos gaskets and braided packing in valves, flanges, pumps, condensers, and turbine glands (Hassayampa carried both general-purpose and aviation-grade fuels, requiring extensive gasketed connections)
- Cargo pump condensers and steam-generator condensers (Foster-Wheeler) requiring asbestos-insulated fittings
- Insulation jackets on cargo pumps, transfer pumps, and stripping pumps
- Vinyl asbestos floor tile throughout the habitable spaces
The Hassayampa’s role as a fleet oiler meant her crew handled fuel-system equipment specifically — pumps, valves, manifolds, hoses — all of which used asbestos gasketing and packing materials. Bosun’s Mates and Refueling Detail crew in addition to engineering ratings worked routinely around this equipment during underway replenishment operations.
VA Benefits for Hassayampa Veterans
The Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions presumed to be service-connected for Navy veterans with documented asbestos exposure. The detailed Hassayampa equipment manifest is direct evidence of the asbestos-containing materials her crew worked around for 36 years.
