This is a 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
Contracted designers: "B" – Bechtel "C" – Combustion Engineering "G" – General Electric "W" – Westinghouse
