What is the propulsion system of the FORD Class (CVN 78 and higher) carriers?

• A. Two gas turbine engines
• B. Two nuclear reactors
• C. Hybrid power systems
• D. Conventional boiler systems

Answer: (B)

The FORD Class aircraft carriers, starting with CVN 78, utilize two nuclear reactors as their propulsion system. This design allows the carriers to operate at high speeds and extend their operational range without the need for refueling in the same manner as conventional fuel systems. Nuclear reactors provide a virtually unlimited range of operation, as the fuel can last for several years before needing replacement. This capability is crucial for extended missions and enhances the strategic advantage of these carriers.

Moreover, the incorporation of nuclear power contributes significantly to the overall energy efficiency and operational capabilities of the vessel, enabling it to generate the necessary power for propulsion as well as for shipboard systems and aircraft catapult operations. This design choice reflects a long-standing tradition in U.S. Navy aircraft carrier propulsion, prioritizing operational endurance and versatility at sea.
