The UK Navy’s Trafalgar Class nuclear-powered attack submarine, HMS Talent, is the first to undergo Babcock’s 13-month revalidation and assisted maintenance period (RAMP) at Devonport Dockyard following the introduction of the Contracting for Availability approach.

The Talent upgrade includes a full gearbox strip-down, removal and replacement of internal pinions for off-site machining, and represervation of the emergency cooling hard tank with an enhanced coating.

Talent will also undergo a combat systems capability upgrade including communications coherency in submarines (CCSM) final increment stage two, sonar 2076 stage 5 and a defence information infrastructure (DII).

The gearbox project has been jointly developed by Babcock, DE&S, David Brown Gearing and BAE Systems.
