HMS Clyde becomes first ship built in Portsmouth for nearly 40 years 14 Jun 06 The first complete ship to be built in Portsmouth Naval Base for nearly 40 years has been loaded out from the VT Shipbuilding assembly hall today, Wednesday, June 14 2006. The launching of the 80m Offshore Patrol Vessel Helicopter (OPVH), HMS Clyde, marked the renaissance of shipbuilding at the Base turning the clock back to the launch of the Leander Class frigate HMS Andromeda in May 1967. http://www.mod.uk/DefenceInternet/DefenceNews/EquipmentAndLogistics/HmsClydeBecomesFirstShipBuiltInPortsmouthForNearly40Years.htm HMS Clyde is an enhanced River Class design with a helicopter deck capable of accepting helicopters up to the size of the new Merlin aircraft, increased accommodation to cater for an embarked force, a 30mm gun, higher levels of survivability and surveillance radar. The new design is built with increased watertight subdivisions for a higher level of survivability, and incorporates active fin stabilisers to improve seakeeping and expand the operating envelope for helicopter operations. She will accommodate a crew of 36 (six officers, nine senior rates and 21 junior rates), berthed in single or twin berth cabins with en suite facilities. There will be additional accommodation for up to 20 extra personnel, which could be an embarked military force, trainees or headquarters staff.
