List of United States naval reactors
This list of United States Naval reactors is a comprehensive list of all naval reactors designed, built, or used by the United States Navy.
Reactor designations
Each nuclear reactor design is given a three-character designation consisting of a letter representing the type of ship the reactor is intended for, a consecutive generation number, and a letter indicating the reactor's designer.Ship types:
- "A" – aircraft carrier
- "C" – cruiser
- "D" – destroyer
- "S" – submarine
- "B" – Bechtel
- "C" – Combustion Engineering
- "G" – General Electric
- "W" – Westinghouse
