USS Ranger (CV-61) — Asbestos Aboard the Forrestal Class Carrier

USS Ranger (CV-61) — a Forrestal class large aircraft carrier — was laid down at Newport News Shipbuilding in August 1954, launched in September 1956, and commissioned in August 1957. The ship was powered by eight Babcock & Wilcox high-pressure boilers generating steam for four sets of Westinghouse geared turbines producing 280,000 shaft horsepower. USS Ranger was homeported at Naval Air Station Alameda, California throughout most of its service life, conducting sustained Western Pacific deployments during the Vietnam War era from 1964 through the war’s end and continuing Cold War deployments through the early 1990s. The ship participated in seven combat deployments to Vietnam, providing carrier air support from Yankee Station in the Gulf of Tonkin. USS Ranger was the last conventionally powered carrier on the West Coast, decommissioned in 1993 after 36 years of commissioned service. The eight-boiler steam propulsion plant throughout Ranger was insulated with asbestos-containing materials consistent with Forrestal class construction, with Boiler Tenders and Machinist’s Mates maintaining the asbestos-insulated steam plant through the ship’s Vietnam combat and Cold War Pacific deployment service.

Forrestal Class Eight-Boiler Plant Asbestos

Ranger’s eight-boiler plant incorporated extensive asbestos insulation:

• Babcock & Wilcox boiler casing insulation — the eight Babcock & Wilcox boilers in Ranger’s four boiler rooms were insulated with asbestos block insulation on boiler casing exterior surfaces, asbestos pipe covering on boiler steam drum and superheater connections, and asbestos rope and cement on boiler header connections. Boiler Tenders maintaining the boilers during Vietnam combat deployments and Cold War Western Pacific operations worked in continuous proximity to the asbestos boiler casing insulation throughout each engineering watch rotation in the ship’s boiler rooms
• Westinghouse main turbine insulation — Ranger’s Westinghouse geared steam turbines driving the four propulsion shafts were insulated with asbestos block on turbine casings and asbestos lagging on the high-pressure and low-pressure steam piping connecting the boilers to the turbines. Machinist’s Mates tending and maintaining the turbines in Ranger’s four engine rooms worked in the asbestos-insulated turbine spaces throughout their propulsion plant watch standing
• High-pressure steam main insulation — the high-pressure steam distribution mains connecting Ranger’s eight boilers to the four turbine sets were insulated with asbestos block and asbestos pipe covering along their full lengths in the engineering spaces. The extensive high-pressure steam piping system in Ranger’s engineering plant represented one of the most significant sources of asbestos exposure in the ship’s propulsion spaces

Vietnam War-Era Service and Asbestos Maintenance

Ranger’s Vietnam deployments placed heavy demands on the steam plant:

• Combat operations steam plant maintenance — USS Ranger’s seven combat deployments to Vietnam required sustained high-tempo carrier air operations, maintaining the eight-boiler steam plant at high operational tempo to support continuous flight operations from Yankee Station. The demanding operational schedule during Vietnam combat deployments intensified the frequency of boiler and turbine maintenance operations, increasing the number of maintenance evolutions in which Boiler Tenders and Machinist’s Mates disturbed asbestos insulation on the steam plant components during the Vietnam deployment period
• WestPac deployment engineering watch — Ranger’s sustained Western Pacific deployments over a 36-year service life meant that generations of engineering ratings — Boiler Tenders and Machinist’s Mates — accumulated extended engineering watch standing in the asbestos-insulated boiler rooms and engine rooms of the eight-boiler propulsion plant throughout the ship’s service life

VA Claims for USS Ranger Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard Navy aircraft carriers. Boiler Tenders, Machinist’s Mates, and crew members who served aboard USS Ranger (CV-61) and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
