Navy/New power plants

The Navy hopes to have the first replacement for the Ohio-class ballistic missile submarine on duty by 2031. When that vessel is launched, the onboard nuclear power plant is expected to last its entire 40-year service life.

That is seven years longer than the current reactors aboard U.S. submarines. 

“Our goal for the new submarines is to have a life-of-the-ship reactor,” said Frank G. Klotz, National Nuclear Security Administration administrator and the Department of Energy’s undersecretary of nuclear security. NNSA is responsible for developing government-owned nuclear power plants.

There are two primary reasons the NNSA is undertaking the new core design, he told reporters in November.
