USS Enterprise (CVN-65) — Asbestos in the World's First Nuclear-Powered Aircraft Carrier

USS Enterprise (CVN-65), the world’s first nuclear-powered aircraft carrier, was built by Newport News Shipbuilding in Newport News, Virginia and commissioned on November 25, 1961. Enterprise was the only ship of her class, representing the cutting edge of American naval technology at the dawn of the nuclear carrier era. Powered by eight Westinghouse A2W pressurized water reactors driving four shafts through steam turbines, Enterprise was the largest warship in the world at the time of her commissioning, stretching 1,123 feet in length. USS Enterprise served 51 years of active service — participating in the Cuban Missile Crisis, Vietnam War combat operations, and Cold War deployments — before decommissioning in 2012 after being relieved by USS Gerald R. Ford (CVN-78). Built in 1961, Enterprise incorporated asbestos-containing steam plant pipe insulation, engineering space insulation, and interior construction materials consistent with the early 1960s construction specifications throughout her hull, creating background asbestos exposure for the approximately 4,600 crew members who served aboard Enterprise during her service life.

Enterprise Nuclear Steam Plant Asbestos

Enterprise’s eight-reactor nuclear steam plant incorporated asbestos in steam system construction:

• Secondary steam system pipe insulation — the secondary steam loop piping carrying high-pressure steam from Enterprise’s eight steam generators to the main propulsion turbines and ship’s service turbine generators incorporated asbestos-containing pipe insulation consistent with the early 1960s steam plant construction specifications. Engineering ratings working in Enterprise’s engine rooms accumulated background asbestos exposure from the secondary steam system pipe insulation throughout their engineering watch assignments
• Main propulsion turbine steam systems — the steam supply systems serving Enterprise’s four main propulsion turbine sets incorporated asbestos-containing pipe insulation and valve insulation consistent with the carrier’s construction period. Machinist’s Mates maintaining main propulsion steam systems in Enterprise’s machinery rooms worked in proximity to the steam system insulation during turbine maintenance operations
• Ship’s service turbine generator steam supply — Enterprise’s ship’s service turbine generators providing ship’s service electrical power were served by steam supply piping with asbestos-containing insulation materials. EM ratings maintaining ship’s service electrical generation systems accumulated background asbestos exposure from the SSTG steam supply system insulation

Enterprise Hull Construction Asbestos

Enterprise’s 1961 construction incorporated asbestos throughout her massive hull:

• Engineering machinery room construction — Enterprise’s engineering machinery rooms, pump rooms, auxiliary machinery spaces, and below-decks engineering compartments were constructed using 1961 construction materials that incorporated asbestos-containing pipe insulation and overhead insulation throughout the engineering space construction. Engineering ratings working in Enterprise’s below-decks engineering spaces accumulated background asbestos exposure from the engineering space construction materials throughout their engine room watch assignments
• Crew berthing and living space construction — the crew berthing compartments, crew mess decks, and living spaces throughout Enterprise’s hull that accommodated her 4,600-person crew were constructed using 1961 interior construction materials incorporating asbestos-containing pipe insulation, overhead construction, and insulation board in the hull interior. The large crew population living aboard Enterprise for deployments of six months or more accumulated background asbestos exposure from the ship’s interior construction throughout extended underway periods
• Aviation and hangar deck spaces — the hangar deck compartments, aviation fuel system spaces, and aircraft maintenance areas within the Enterprise hull incorporated asbestos-containing construction materials consistent with the carrier’s 1961 construction specifications. Aviation ratings working in Enterprise’s below-hangar-deck spaces accumulated background asbestos exposure from the carrier’s construction materials

VA Claims for USS Enterprise Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard Navy nuclear aircraft carriers. Officers and crew members who served aboard USS Enterprise (CVN-65) and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
