their was a post here where it said that INS satpura is delayed because of the delay of klub missiles
Dear Chinese Bhai,
C'mon, don't ask embarrassing questions! We found a Russian bhai who needed money for his son's college fees at Stanford, and hey! instant indigenous development happened! We didn't even need a steel plant for it. We aren't good at reverse engineering yet, but as our reverse engineering budgets increase, we are getting better.
Aircraft carrier: A mind-boggling building job (was once offered to India)
In a shipyard in Scotland the future of the Royal Navy is slowly taking shape. But the construction of the aircraft carrier HMS Queen Elizabeth is a mammoth task.
Imagine an aircraft carrier as a 65,000-tonne jigsaw puzzle and you have got a good idea of the scale of the building of HMS Queen Elizabeth.
The pieces are being built at six shipyards around the UK and will be slotted together at Rosyth in Fife using an enormous crane which was transported by sea from China.
Around 10,000 workers across Britain are employed on the £5bn project with up to 25,000 engaged in building components for the Lockheed Martin F-35 aircraft.
The carrier will have 12 F-35s, or Joint Strike Fighters, costing around £65m each.
"It's the biggest shipbuilding project for the Royal Navy ever and is second only in engineering terms to the Olympics," says the man in charge of the whole project, David Downs, engineering director with the Aircraft Carrier Alliance (ACA) consortium.
"All my nights are sleepless, worrying about it," he jokes.
The Queen Elizabeth and sister ship Prince of Wales will be far bigger than the Ark Royal but still significantly smaller than US equivalents.
Downs and his team designed the ships using computer software - every inch mapped out electronically with laser-guided measurements which ensure each part fits together.
Uniquely, a team of assessors from Lloyd's Register are on hand at all the yards to check the work as it proceeds.
BAE Systems is part of ACA and at its Govan yard in Glasgow, integrated work teams manager David Thomas gives a tour around one huge segment of the ship.
Clambering under the hulk, wearing only a hard hat for protection, it's hard not to think of what would happen if the frame holding up 14,000 tons of steel gave way. But Thomas is reassuring on the yard's safety record.
He has been supervising the insertion of some of the 450 prefabricated cabins and 150 shower rooms - made by a firm on Teesside - in the ship's innards. He carries with him a small manual showing where everything fitted.
Anyone who finds the instructions to flatpack furniture a challenge would find it mind-boggling.
The whole process starts with the arrival of huge sheets of steel. They are "burned" into various shapes and sizes - some of them quite small - which are welded into position.
Gradually the sections become bigger as deck after deck is welded together.
One of the Govan team is Lyn Gordon, 23, an apprentice fabricator and one of a number of women working on the project.
"My fascination with shipbuilding came from living on the Clyde," she says. "I realise that it will eventually be an aircraft carrier and I will get to see it turning from a sheet of a metal, to a component, to HMS Queen Elizabeth."
The first segment from Govan should be ready this summer and will be towed by barge, around the northern tip of Scotland, to Rosyth.
At Rosyth the dry dock is ready for the assembly process. Last month the crane arrived from Shanghai, having squeezed under the Forth Bridge at low tide.
Rosyth has List X status, meaning everyone working there has to be security cleared, including the 50 Chinese workers who are helping to erect the 93m crane.
The first piece of steel was cut in 2009 but HMS Queen Elizabeth will not be finished until 2016 at the earliest, and may not be ready for action until 2020.
The construction of her sister ship, the HMS Prince of Wales, will overlap and the current plan is for one of them to be operational while the other would be kept in "extended readiness".
With the Ark Royal's fleet of Harrier jump jets being decommissioned the Navy will be without carrier-based planes for almost a decade.
Recent events in Libya have showed the importance of mobile air power.
The MoD complicated matters in October when it decided, in the Strategic Defence Review, to fit the carriers with catapults and arrester wires.
The "cats and traps" will enable them to fly the carrier variant F-35 and will also enable US and French jets to land on the deck. But it will also delay the completion of the carriers.
"If they get the two ships in the form they are expected they will be enormously capable ships. It's like having a piece of Britain you can place anywhere in the world," says naval historian Nick Hewitt.
Aircraft carriers are arguably the ultimate symbol of military prestige, a mobile projection of military might.
The Royal Navy pioneered carriers, explains Hewitt, head of attractions and collections at the Portsmouth Naval Base Property Trust. The first carriers were converted battlecruisers like the 7,500 ton Ark Royal, whose biplanes first saw action in February 1915 against the Turks in the Dardanelles.
Since the 1930s, US carriers have dwarfed their British allies, Hewitt notes.
"The US carriers were designed for the Pacific and to be away from base indefinitely. The British carriers were designed to operate in the North Sea, the Mediterranean and the North Atlantic or from bases in Singapore or India."
HMS Invincible, which fought in the Falklands, and HMS Ark Royal, which was recently pensioned off, weighed in at a puny 22,000 tons compared to the American carriers such as the USS George H W Bush, at 101,000 tons. The QE Class weighs in in between - at 65,000 tonnes full displacement.
When it is finally ready the Queen Elizabeth will only be able to navigate the Forth Bridge and reach the open sea by waiting for low tide, and even then they will have to retract the radar masts.
The project has had its critics.
The former deputy chairman of Babcock - which is part of the ACA - Lord Hesketh resigned in November after describing the project as a "disaster".
He told the BBC the carriers could have been built for a fraction of the cost at a shipyard in South Korea and claims the project only went ahead in its present form because of the number of jobs it preserved.
But whatever the controversy over the carriers and the cost, the effort involved will be phenomenal.

I hope you are not talkin about F35 C. Its the carrier version and costliest among the three version. Earlier its cost was around 150 million $. I don't know as their are reports of cost escalation...I think F35B the marine version is best...there was talking of going for either cheaper "C" versions or the F-18 SH
Actually India was a serious customer and IN showed a bit interest also, presentation were made by BAE, but later it was decided that India will go with Gorshkov and next AC's will be built in India itself...their are already plans for 3 under P71 and 4th one is Gorshkov, i don't think India will go for it....but yeah IN might be interested for the design for IAC2.once these are completed they will almost immedialty be mothballed and hopefully one sold off.( India is/was an option, what do you think- will India pursue this??)
Can anyone answer my questions.... ??
Any body has any update on P17a frigates and P28A corvettes ???
Work on P17a was supposed to start this year, has it started or is there any delays ??
By making the superstructure, which is the upper part of the ship that rests on the hull, of lighter composite material, the 2,500-tonne warships will become lighter, stealthier and far more stable in the water. Already acclaimed as world-class warships, composite superstructures will make them amongst the most effective submarine hunters in any of the world's navies.
Business Standard has learned that the ministry of defence will shortly issue tenders to three shipbuilders with extensive experience in fabricating composites. Kockums of Sweden, a subsidiary of ThyssenKrupp Marine Systems, which builds the world's stealthiest warships, the 650-tonne Visby class corvettes, is a leading contender; also in the fray are Greek shipbuilder, Intermarine; and Korea's Kangnam Corporation.

Any progress on the above article ??? Are we really going for composite superstructures from 3rd ASW corvette of P28 project ?
I don't know about this switch between B and C.....but yeah you are right....B is more costlier...I read this way back, thats why didn't remember it exactly...F35B costs around 150 million$...and reason is obvious.No I'm pretty sure they were discussing a switch FROM "B" already ordered to "C"
There are only speculations...IAC2 designed is being worked out and nothing is made public yet...Anyone know the chances of IAC 2 having EMALS?

In October 2010, press reports suggested that the Conservative-Liberal Democrat coalition government were considering reducing the order for the F-35 from 138 to a currently unspecified but lower number as of the 2010 Strategic Defence and Security Review. The proposed cuts would also close RAF Lossiemouth, chosen as the main operating base for the F-35.[38] On 19 October 2010 Prime Minister David Cameron announced in the Strategic Defence and Security Review that the UK would procure an unspecified number of F-35Cs, to fly from only one of the Queen Elizabeth class aircraft carriers, instead of the F-35B. This change will require the aircraft carrier to be equipped with catapults and arresting gear
Can anyone answer my questions.... ??
thanx...but can you post something official ??Mazagaon Docks can begin the construction by end of 2011 while GRE will begin by end of 2012 or early 2013
So FREMM is selected ??? Cool...Italian company Finceranti and French DCNS will provide design consultancy apart from certain internal subsystems for these ships
thanx...but can you post something official ??
So FREMM is selected ??? Cool...
Also what happened to P28A...Kockums AB was supposed to provide help for that, i mean there were 8 more shipyards but the Kockums AB was the leading because of Visby...
