Our History & the NNPP


Since 1956, at the direct request of the Navy's Admiral Hyman G. Rickover, our employees have successfully supported our nation's fleet and Sailors in various aspects of the design, development, and continuing support of Naval Nuclear Propulsion equipment—a vital part of our nation's defense. We work with our many partners to deliver and maintain safe, reliable, and cost-effective products that ensure the long-term viability of the Naval Nuclear Propulsion Program (NNPP).

The NNPP comprises the military and civilian personnel who design, build, operate, maintain, and manage the nuclear-powered ships and the many facilities that support the U.S. nuclear-powered naval fleet. The Program has cradle-to-grave responsibility for all naval nuclear propulsion matters, and elements include:

  • Research, development, and support laboratories.
  • Contractors responsible for designing, procuring, and building propulsion plant equipment.
  • Shipyards that build, overhaul, and service the propulsion plants of nuclear-powered vessels.
  • Navy support facilities and tenders.
  • Nuclear power schools and Naval Reactors training facilities.
  • Naval Nuclear Propulsion Program Headquarters and field offices.
