    Wow,
    great video. I don´t know why I always thought the AL-1 laser would be invisible to the naked eye. How do they generate enough energy to project such a powerful laser along such distances? Additional electric generators in the fuselage or the engine power is enough?

    Neither, it’s powered by a chemical reaction consuming onboard stores of liquid reactants.

    Aircraft carrier contracts named

    Aircraft carrier contracts named

    Contracts to supply the Royal Navy’s next generation of aircraft carriers, worth a third of a billion pounds, have been announced. Five new suppliers are to benefit from the programme to build the Queen Elizabeth Class flagships.

    The companies will provide fire-fighting equipment, air conditioning, paintwork and scaffolding

    Some of the contracts have been secured by companies based in Glasgow, Yorkshire and Manchester.

    Supporting jobs

    One of the most challenging contracts is an £85m contract to float the various blocks of the two super-carriers to their assembly point in Rosyth, Fife. That has been awarded to Henry Abrams of Glasgow.

    Other contracts to provide heating, ventilation and air-conditioning, worth £120m, have been awarded to Imtech, a Dutch company with UK headquarters in Billingham on Teesside.

    Paint and access, including all the scaffolding required during the build process will cost £105m, and has been awarded to Pyeroy of Gateshead, and Cape of Wakefield, which will form a joint venture based at Rosyth.

    The ships’ fire-fighting systems, including sprinklers, are to be provided by Tyco of Manchester, at a cost of £15m.

    The 65,000 tonne ships are to have 2,500 kilometres of cabling, being installed for £8m by AEI Cables of Birtley in County Durham.

    With much of the steel already ordered, the total of sub-contracted orders for the super-carriers is expected to reach about £1.5bn.

    “Once in service, these ships will provide the UK Armed Forces with a vital and extensive naval capability,” said Geoff Searle, director of the Aircraft Carrier Alliance, which includes the three lead contractors and the Ministry of Defence.

    “Most of these contracts, placed for the Aircraft Carrier Alliance will support local economies and jobs throughout the UK regions,” he continued.

    Challenging task

    In the past 12 months, the first steel of the ships’ hulls has been cut at Govan in Glasgow.

    Work has also started on HMS Queen Elizabeth at three other yards, as well as the dock in Rosyth where the ships are to be assembled.

    “This news should reassure those who doubt this government’s commitment to the programme,” said Quentin Davies, the UK defence equipment minister.

    “These sub-contracts will contribute thousands of jobs throughout the supply chain in addition to the thousands of jobs at the main shipyards which are building the ships. The build phase of the Carrier programme is now well under way”.

    Michael Abram from Henry Abrams said being awarded the transport contract added to the company’s long-seafaring history, and would be challenging.

    “We now plan to employ naval architects, structural engineers, design engineers, graduates, and administration staff to work alongside our existing staff and consortium partners to ensure safe and successful delivery of all cargoes to Rosyth,” he said.

    The super-carriers are to be three times the displacement of the Royal Navy’s current Invincible class of carrier, and the first of them is due to enter service in 2016.

    That’ll teach me to waste time cutting-and-pasting …

    Did the HMS Argyll (F231) which to my knowledge never got a major refit this decade soon be in line for one?

    With the service lives of the Type 22s and Type 23s now extended by another four years (HMS Argylls 2019/2023).

    Will she soon get a major udgrade? Or just enough repair to keep her functional?

    Rosyth wins warship missile refit

    The Royal Navy warship HMS Argyll is to have her missile system upgraded in a major £19m refit in Fife.

    The Type 23 frigate has just arrived in Rosyth for a year-long overhaul by 120 Babcock staff who will provide her with new electronic guns.

    It will also get a new weapon control system, a new computer system, upgraded living quarters, and a sonar upgrade.

    The updated Sea Wolf missile system is similar to that used on the Navy’s new Type 45 destroyers

    It will boost the power and accuracy of the weapons and is designed to sustain the capability of the Type 23 frigates even as technology moves forward.

    Commodore Brian Archibald, MoD head of surface combatants, said the updated Sea Wolf weapons system could counter a target travelling at twice the speed of sound from over 20 miles away.

    He said: “We are rolling this update out across the frigate fleet in response to the increasing threat of faster, lower flying missiles.

    “The update is so advanced it will even guard against future missile developments.

    “In addition to war fighting roles the ship can conduct a wide range of tasks including anti-piracy and anti-smuggling activities, disaster relief work and surveillance operations, particularly in the northern Arabian Gulf.”

    Scottish Secretary Jim Murphy, who was in Fife on Friday, said: “It’s great to see a resurgence in the ship yards thanks largely to a number of defence contracts over the past decade.

    “Companies in Fife such as Babcock work hard to win these contracts and ensure staff have the skills and expertise to deliver challenging and important government projects.”

    Mike Pettigrew, managing director of Babcock at Rosyth said: “The award of this contract continues to allow us to develop the high level of skill sets required to support the Royal Navy, and further strengthens our partnering relationships with the MoD through the Surface Ship Support Alliance.”

    How can the MOD make such a right mess of the armed forces! Our combat units have been badly (criminally) let down!

    It just beggars belief … just scrap the lot and start again with the RN as a fisheries protection farce, the RAF as search/rescue and the army to back up the police … although even that would not keep the bean counters happy!

    I agree … it would also remove the temptation to go to war with sandy countries that the government can’t seem to resist.

    This is my first post on this forum so forgive me if I screw up!

    Yesterday, the attached flew past our window as explained in my Phlog. Is it a Typhoon and how common is it to have one fly past your window?

    Sweet!! 🙂

    Well, I don’t agree with RAF Aircraft from operating from RN Carriers in the first place

    Why not?

    Was there ever any use for the 2-stroke Crecy envisaged?

    The Eagle was fitted to the Westland Wyvern.

    Yes, but only as a test powerplant until turboprops came along. What did the designers at Rolls-Royce plan to fit the Eagle into?

    Thanks everyone, loads of info!

    It’s interesting to note that while engine power went up and up throughout the course of the war the power:weight ratio didn’t really increase all that much. Is that right? At least until the Crecy was built … does anyone have more details than Wikipedia on the Crecy engine? I know they had a prototype built and running but it didn’t seem to produce as much power as you would expect from a 2-stroke.

    The other thing I was wondering is since the Eagle was so enourmous and heavy, what was it supposed to fit into? Were they planning on shoehorning it into a Spitfire/Spiteful for example? Or was it intended only for new aircraft, e.g.

    Even if they are as good as the AH-64D/RAH-66 considering weapons, power and strength, they can’t be as good as the Longbow/Comanche team. These are really the top when we’re talking about radar, stealth and other high-tec qualities.

    How on Earth would you know? Why don’t you give us the inside scoop on the capabilities of the Comanche?

    The H-1 Upgrades, which involves the AH-1Z programme, has exceeded its original budget estimate by 140% since beginning in 1996.

    LOL, why didn’t they just buy Blackhawks and Apaches?
