    Why is she termed river class
    Things fall apart; the centre cannot hold;
    Mere anarchy is loosed upon the world,
    The blood-dimmed tide is loosed, and everywhere***
    The ceremony of innocence is drowned;
    The best lack all conviction, while the worst
    Are full of passionate intensity.

      Because she is named after a River, like the others in the class. Clyde, Severn,Tyne etc.


      Catch-22 says they have a right to do anything we can't stop them from doing.

                HMS Clyde in the Falklands


                RV with HMS Southampton.


                HMS Dumbarton Castle, RFA Gold Rover and HMS Clyde

                Clyde has finally arrived in the Falkland Islands and has relieved HMS Dumbarton Castle as the Falkland Islands Patrol Vessel. She arrived on 21st September and, on the first day in theatre, hosted 35 personnel from Mount Pleasant, the military base in the Falklands, for an introductory brief on the ship’s capabilities. After two days of settling in, Clyde, along with HMS Dumbarton Castle, underwent a weeklong period of training under the control of staff from the Flag Officer Sea Training organisation who flew down from the UK for the period.

                The training included fire fighting and damage control, Air Defence exercises, self protection exercises against fast inshore attack craft, beach landings and various navigation exercises including pilotage, a replenishment at sea and Officer of the Watch Manoeuvres.

                  Just found a presentation on the River class: http://www.offshorepatrolvessels.com...ets/opvsrn.pdf

                  £30 million cost reduction for RN over 5 years (lease, manning, CLS)
                  3 OPVs delivered within 3 years of signature of contract
                  Contract amount (commerically sensitive) excludes crew, fuel & food, 75% lease, 25% support

                  320 operational days (230 patrol / 5 transit / 46 standoff / 19 OST & SCWT, 2 as required)

                  The remaining 20 days are available to the RN if required (on repayment!)

                  Fishery protection takes up a total of 700 days tasked by MFA (pay proportion of operating costs (1 days costs MFA around £8k)), 42 day patrol, 12 days at sea, 2 days stand off. Doesn't patrol Scottish waters

                  2007/8 - 6478 Sightings, 1311 boarding, 22 detentions

                      Any idea what the average fuel consuption per hours is at cruising speed?

                      Given the P50s are a bit thirsty I wonder how it works out pound for pound.

                            UK Awards £348 Million Warship Contract

                            Whitehall today signed a £348m deal with shipbuilding BAE to provide the Fleet with three new patrol ships.

                            Work on the first of the trio, which will be similar to vessels built for the Brazilian Navy, will begin on the Clyde in October, with it in RN hands in 2017.



                            THIS is the future shape of the busiest Royal Navy warships in UK waters.

                            Whitehall today signed a contract with BAE Systems to build three new patrol vessels for duties around the mother island – and beyond – from 2017.

                            Just shy of £350m is being spent with the defence firm, which will construct the trio in its yards on the Clyde.

                            The new vessels will be based on the Amazonas class of patrol ships BAE built for the Brazilian Navy in its Portsmouth yard – and which were on security duties during this summer’s World Cup.

                            All three will be bigger than the existing River class ships, which are on duty around the UK for more than 300 days a year, largely focusing on fishery protection work, but also acting as the RN’s eyes and ears in home waters to stop smuggling and terrorism and to help out in emergencies.

                            The ships in the as-yet-unnamed class will be 90 metres (295ft) long, reach at least 24kts, be able to host a Merlin helicopter and have a range of more than 6,300 miles – enough to take them from Portsmouth to South Africa or ‘Pirate Alley’ between Somalia and Yemen; the vessels are being designed to patrol the broader oceans as much as waters around the UK.

                            Work on the first ship will begin in October and it is due to be handed over to the RN in three years’ time. BAE has already begun work acquiring engines and gearboxes.

                            The £348m deal will sustain around 800 jobs in the shipbuilding industry and tide the BAE yards over between work ending on new carrier HMS Prince of Wales and construction beginning on the first Type 26 frigates later this decade.

                            The next defence review will determine whether the three new ships will be replacements for the three River-class vessels (which have been in service since 2003) or will be in addition to them.

                            Yet another western navy plans to build OPVs with a flight deck, shows how to best utilise a 90 - 100 metre platform.

                            £348m stg equates to €437.67m, which works out to be €146m per ship.......awful lot......... imho

                              Is that 30mm main armament? Looks like it will have air search radar.

                              Would be interesting to compare its crew living space versus the P60's.

                                The EU should be investigating!

                                Basically if the RN hadn't have placed more orders they would have to pay the yard truck loads of money as part of a previous contract.
