    Gourock shoppers get close-up view of Royal Navy submarine as she carries out manoeuvres on the Clyde

    Shoppers in Gourock got a close-up view of a Royal Navy Astute Class submarine, as she carried out manoeuvres on the Clyde.

    The attack vessel, which was built by BAE Systems in Barrow, and will be based at Faslane in Gareloch, will never have to refuel, as she is fitted with a Rolls Royce PWR2 nuclear reactor which will last for the twenty five year service life of the sub.

    At 318 feet in length, and a capability to detect an enemy ship from a staggering distance of 3,000 nautical miles, the Astute Class vessels are the UK's most powerful attack submarine.

    UK nuclear submarine collides with merchant vessel off Gibraltar
    [​IMG]

    [​IMG]

    One of the UK's newest nuclear-powered submarines has docked in Gibraltar after a collision with a merchant vessel during a training exercise.

    The Royal Navy said it has launched an immediate investigation after HMS Ambush was involved in the "glancing collision" while submerged off the coast of the British territory.

    There is "some external damage" but no crew members were injured, it added.

    The Astute-class attack submarine's nuclear reactor was undamaged.

    In a statement on the Ministry of Defence website, the Navy said the incident took place at approximately 13:30 local time on Tuesday.

    Further checks
    "We are in contact with the merchant vessel and initial indications are that it has not sustained damage.

    "The submarine suffered some external damage but there is absolutely no damage to her nuclear plant and no member of the ship's company was injured in the incident."

    Further checks would be carried out but there are no safety concerns, said the Navy.

    Photographs of Barrow-built HMS Ambush arriving in Gibraltar appear to show damage to the front section of its conning tower.

    The submarine is reported to be a regular visitor to Gibraltar, having last stopped in the territory in June and March.

    The Royal Navy's Astute-class submarines are Britain's largest and most advanced attack submarines - HMS Ambush is 97m (318ft) in length, cost £1.6bn and carries torpedoes and Tomahawk cruise missiles.

    It joined the fleet at the Faslane naval base in 2013 after two years of sea trials.

    Two other Astute-class submarines - Astute and Artful - are in service and four more vessels - Audacious, Anson, Agamemnon and the yet to be named seventh - are in various stages of construction.

    The nuclear reactors of the Astute-class submarines will not need refuelling in their entire 25-year life and they make their own air and water, enabling them to circumnavigate the globe without needing to surface.

    Astute grounding
    In 2010, nuclear-powered submarine HMS Astute ran aground near the Isle of Skye during sea trails and was stuck for about 10 hours.

    It was also damaged in a collision with a tug, the Anglian Prince, which tried to free it.

    And there were protests in 2000 when the Royal Navy nuclear submarine HMS Tireless docked for repairs in Gibraltar after a crack was found in a cooling pipe near its nuclear reactor.

    Residents in Gibraltar and southern Spain staged demonstrations over environmental concerns and the presence of the submarine became the subject of a high-profile campaign by Greenpeace.

    BAE Systems to begin building new British nuclear submarines

    Britain's ministry of defence said on Saturday that construction work will begin on the country's new nuclear submarines, announcing nearly 1.3 billion pounds of new investment with defence firm BAE Systems (BAES.L).

    Lawmakers backed renewing Britain's ageing nuclear weapons system earlier this year, a multi-billion pound project regarded as key to maintaining the country's status as a world power following its vote to leave the European Union.

    "The investment will support delivery of the Government’s commitment to retain the Trident-based continuous at sea deterrent – the ultimate guarantee of our safety – and build the new fleet of four Successor Ballistic Missile submarines," the defence ministry said in a statement.

    BAE Systems said the first new submarine will enter service in the early 2030s.

    French contract' for Britain's new fleet of nuclear submarines 'betrays UK steelworkers'

    5 October 2016 • 8:36am
    British steelworkers have been betrayed, a union boss claims, as it was reported that a foreign firm will supply metal for the new fleet of nuclear submarines.

    Defence Secretary Michael Fallon is today due to press the button to begin work on the £41 billion Successor submarine plant at BAE Systems’ plant at Barrow-in-Furness in Cumbria.

    However, the flagship project of the Government’s defence policy has been rocked after it was revealed that French group Industeel will supply steel for the new submarines' "pressure hulls", the outer part of the 15,900 tonne vessels, which will each carry 16 nuclear missiles.

    Britain’s steel industry is in crisis, having lost thousands of jobs over the past two years as it buckles in the face of competition from state-subsidised Chinese imports, high energy costs and a less favourable tax regime than enjoyed by European rivals.

    What do voters at the home of Trident think? Play! 01:28

    High-profile failures in the steel industry have included SSI’s plant in Redcar and Caparo’s collapse into administration. Tata has cut thousands of jobs and a question mark hangs over the future of its giant Port Talbot plant in Wales.

    Roy Rickhuss, General Secretary of steelworkers union Community, said: “The Government has said time and time again that big infrastructure projects should make the most of British steel, yet here we have the Defence Secretary boasting about cutting steel that was made abroad.

    “It’s a slap in the face to hard-pressed British steelworkers.”

    Mr Rickhuss called the Trident replacement “a fantastic project that will support British manufacturing” but called on the Government to use British steel “wherever possible”.

    Commons debates the future of Trident Play! 01:32

    A spokesman for BAE declined to confirm the origins of the steel being cut by Mr Fallon today as part of a ceremony to mark the start of the submarine work.

    It is understood that no contracts for the supply of steel will be awarded today.

    The company sources steel according to the technical specifications of the submarines and it is understood that the majority of steel for Successor is purchased within Europe, including the UK.

    However, a source close to the company said: “On the pressure hull steel, we expect to buy from Industeel in France who provide the quality we need.”

    A spokesman for the Ministry of Defence said: "The Successor programme represents billions of pounds of investment in thousands of British jobs across hundreds of firms from Scotland to the South East. We source steel from the UK where possible and from international suppliers when necessary. There was no UK bid for this part of the build. It is an early stage of the programme but there will be British steel in the new submarines."

    Speaking at the Conservative Party conference earlier this week, Mr Fallon described the Successor project as huge programme which “will benefit businesses from Barrow to Berkshire, from the north of Scotland to Tyneside”.

    its not just china it was the lack of trust in British industries. tata was the reason for the f*ck up, china just finished them off.

    Those specs are remarkably of the existing Vanguard-class, are they not?

    I don't know how accurate or official the attached artist impression is, but it clearly shows only 12 missile silos.

    On topic, isn't this the kind of economic outcome that all those who voted for Brexit wanted to avoid?

    How is this news being reported in France @Vergennes ?
