USS Ranger (CV-61) — Asbestos Aboard the Kitty Hawk-Class Pacific Carrier

USS Ranger (CV-61) was a Kitty Hawk-class conventional aircraft carrier commissioned in August 1957 at Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia. Homeported throughout most of her career at Naval Air Station Alameda, California, Ranger served seven Vietnam combat deployments between 1964 and 1973 — one of the highest Vietnam deployment totals in the carrier fleet — and continued in active service through the Gulf War (Operation Desert Storm, 1991) before being decommissioned in July 1993. Built to the construction standards of the late 1950s, Ranger incorporated asbestos insulation throughout her steam plant, engineering systems, and interior spaces.

Steam Plant and Engineering Asbestos

Ranger’s Kitty Hawk-class steam propulsion system used asbestos insulation extensively:

• Boiler plant — Ranger’s eight high-pressure boilers used asbestos-containing boiler lagging on exterior surfaces, asbestos combustion chamber refractory brick, and asbestos sealing materials at boiler access points. BT ratings maintaining Ranger’s boiler plant in the firerooms worked in sustained proximity to asbestos-containing lagging throughout their engineering assignments
• Main steam piping — the main steam piping distribution from Ranger’s firerooms to the enginerooms and auxiliary steam loads used asbestos pipe covering throughout the high-temperature steam piping in the engineering spaces. The pipe covering — asbestos magnesia block under canvas jacketing — was the primary engineering space asbestos source for the MM and BT ratings on engineering watch and maintenance duty
• Steam catapult systems — Ranger’s steam catapult launch systems for aircraft operations used high-pressure steam from the ship’s main steam plant, with asbestos-insulated steam piping and components in the catapult system serving the flight deck launch cycle

Extended Vietnam Operational Tempo

Ranger’s seven Vietnam combat cruises created sustained crew asbestos exposure:

• Seven combat deployments over the Vietnam era meant that crew members serving multiple Ranger tours accumulated compounded asbestos exposure from the ship’s steam plant insulation over extended periods. The high operational tempo of Vietnam combat deployments kept engineering ratings in the firerooms and enginerooms under sustained high-temperature operating conditions that degraded the pipe covering insulation and increased fiber release

Interior Construction Asbestos

Ranger’s 1957 construction incorporated asbestos in interior materials:

• Crew accommodation — crew berthing for Ranger’s complement of over 4,600 personnel used asbestos-containing deck tile and overhead insulation in the late-1950s construction
• Aviation maintenance spaces — hangar deck working spaces and aviation maintenance areas used asbestos-containing deck materials and overhead construction consistent with the 1957 construction standards

VA Claims for USS Ranger Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard Kitty Hawk-class aircraft carriers. Engineering ratings who served aboard USS Ranger and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
