List of United States naval reactors

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

Contracted designers:

• "B" – Bechtel
• "C" – Combustion Engineering
• "G" – General Electric
• "W" – Westinghouse
