15,900 tonnes, submerged[2]
Propulsion:
1 × Rolls-Royce PWR2 nuclear reactor
2 × GEC turbines; 27,500 shp (20.5 MW)
PWR2 - The larger PWR2 plant was designed
to meet the operational requirements of the
larger Vanguard class submarines. The steady
evolution in reactor design has culminated
in the long-life core, which began shore
based testing in 2002. The latest core has
over six times the energy output and over
four times the service life of the original.
These long-life cores are now fitted in the
latest Astute and Vanguard class submarines
