The UK Royal Navy's seventh and last Trafalgar-class nuclear-powered submarine, HMS Triumph, is set to undergo an eight-month refurbishment programme in Faslane, UK.

As part of the programme, which follows its ten-month patrolling deployment in UK waters, the submarine will spend three months out of the water in the shiplift.

HMS Triumph commanding officer commander David Filtness said: "Triumph, the platform and her people, has been working extremely hard for the last two years.

"The focus now is maintenance, providing some much-needed time with families and for professional courses, and regenerating the team for operations later in 2015.

"I expect these next few months will fly by for us all."

In March 2010, HMS Triumph completed a six-year, £300m modernisation programme, involving the installation of sonar systems and upgraded Tomahawk missile system, new command and control system, as well as a new internal fibre-optic computer systems network and improved satellite communications.

"HMS Triumph will resume operations next year and is set for decommissioning in 2022."

The Trafalgar-class submarines are equipped with the Rolls-Royce PWR1 pressurised water-cooled nuclear reactor that powers two General Electric steam turbines, which deliver 15,000shp to one shaft.

The submarine also features both cruise missiles and Spearfish torpedoes, in addition to Thales Underwater Systems 2076 stage four integrated passive / active search-and-attack sonar suite, collision-avoidance radar, two SSE Mk8 launchers and five 533mm torpedo tubes, in addition to Tomahawk Block IV land-attack cruise missiles (TLAM).

Upon completion of the refit programme, HMS Triumph will resume operations next year and is set for decommissioning in 2022.
