Submarine Energy

Powered by an alternative energy source (nuclear), submarines are participating ships of the 2016 Great Green Fleet deployment

Submarine fuel use is closely tracked to meet or exceed planned life expectancy

In port energy use is minimized by powering down systems not needed for habitability and safety

UNCLASSIFIED

Commander, Submarine Force Atlantic

Current Practices & Efficiencies

In port, major systems are de-energized or operated at reduced load• Secured: Radar, Sonar, Atmosphere Control, Fire

Control, Lube Oil Systems, Laundry • Reduced: A/C system reduced to ½ capacity

Regular heat exchanger cleaning

Hull cleaning at every drydocking

Ship transits are planned at most energy efficient speeds• VIRGINIA Class and follow-on classes have life-of-

ship cores
