Worth remembering there are limits to what can usefully be accomodated in a hull of given size. A vessel is a compromise between speed, endurance, sea keeping qualities and stability, fire power and sensor fit, the problem with a lot of the ideas for high capability corvettes is they overload the hull, leave zero room for future growth and end up almost as expensive as a larger frigate offering much better long term capabilities. Somebody say Sa’ar V.
I would take issue with the concept of buying an overly large, underarmed “platform” in hopes of acquiring additional weapons and sensor at a later date – the infamous “mid-life update,” which never seems to materialize in full.
In most cases, there is little point in “leaving room for future growth” because it is rare to see truly substantial – and expensive – upgrades.
The modular approach to capabilities only works if there is the money and will to purchase the applicable modules.
Hit it on the head there Turbina, it gets even worse with Hyundai offering Corvettes, Frigates and Destroyers.
The Korean shipbuilding industry extends well beyond just Hyundai. Even the fairly minor Dae Sun yard can turn out small and inexpensive LPDs quite quickly.
It would be very interesting to compare costs between the UK and South Korea for the MARS requirement.
The whole Rosyth thing is silly considering they will have to spend lots of money expanding the yard for the one off CVF contract when Harland and Wolfe have a basin big enough to do the job.
How did Harland and Wolff manage with the two Ro-
Ro 2700 units? It would have been substantially cheaper to have had Flensburg build all 6?
The problem is UK yards unlike ones in other countries (France, Germany and Spain for example) don’t get orders for large civilian ships like container ships, cruise liners and tankers.
With the trickle of millitary orders its hardly surprising that UK yards are not competative.
US shipyards haven’t seen substantial civilian orders since the Reagan era – lets avoid the “Project America” for the sake of discussion.
American shipyards might not be “commercially” viable, but building schedules and costs for military funded projects haven’t been altogether unreasonable.
Swann Hunter are more than capable of making Frigates and small vessels but the ALSL order was just too much. I have a hunch that if Swann Hunter had been recieving regular orders for Ferries and cargo ships over the last thirty years the ALSL order would of presented few problems for them and easily come in under budget.
With under investment, lack of government support and unions not realising the consequences of their actions its hardly surprising that British ship building is in ruins.
Indeed, Swan Hunter would have been more than capable of finishing both ALSL units on time, and under budget, if there had a been a steady stream of work from 1993 onward.
We all know that the reality was far different.
The UK government are working to a master plan (of which CVF is part) to maintain major shipbuilding skills in the UK. I understand that this is both for industrial and defence reasons.
Isn’t this the same government that should have realized that Swan Hunter had ceased to be a viable shipbuilder in the early 90s – but gave them a contract for two ALSL hulls anyway?
Well, the US would be happy to build the CVF’s or any Carrier in the US for UK. Yet, I don’t see any practical reason for such a move? Further, look at the thousands of jobs that would be lost!
The practical reason is that the UK’s shipbuilding industry has already declined to point where costs and delays are literally killing defense programs. If the British shipbuilding industry has failed to the Type 45 and Astute programs on time and under budget, is there any reason to believe that the CV-F program will be any different?
The United States has maintained a far more capable shipbuilding sector than the UK. The United States Navy is also set to become the biggest customer for the Rolls Royce MT-30 gas turbine.
Another “hospital ship” that´s what we need….
Are you serious?
What is the likelyhood of a ‘Western’ nation (UK, US, EU including Australia and New Zealand) ever being able to purchase a Russian aircraft for their AirForces?
I don’t just mean the modern fighters but also transport aircraft and helicopters.
With several nations actively seeking replacements for aircraft purchased in the 70s and 80s is the purchasing of Russian aircraft a realistic option for these countries, will Vladimir Putin allow MiG, Sukhoi etc to sell their wares to them?
Or does America have such a strong grip on Western airforce equipment?
Perhaps Russian export horizons will broaden, but recent events in London cast doubt upon Russia’s future. Russia could potentially gain a toehold in defense exports to Western countries, but it is also possible that Russia could face sanctions and embargoes.
The size of marine geared turbines or turbo-electric drive is not an unknown quantity and they’re comparable in size to a GT of similar power. And you can get a good idea of the size of modern reactors if you look at submarine power packages, which are compact and highly rated, but substantially bigger than an equivalent GT and frighteningly expensive.
A surface combatant of CG(X) size might require two reactors, whereas even an SSBN normally requires only one.
Costs will indeed be daunting, but so will the space and weigth requirements. The DDG-1000 is designed around a reasonable compact gas turbine/alternator IFEP setup, and a two reactor, turbo-electric setup will surely require a substantial redesign and perhaps even an increase in hull dimensions.
It also goes without saying that CG(X) will also have a far more extensive electronics and missile fit than the DDG-1000. Add together the costs of nuclear propulsion and AAW capabilities, and you might just have a ship that will come close to the first unit costs equivilent to a repeat production CVN.
Call to remodel Eurofighter alliance
By James Boxell, Defence Industries CorrespondentSir Peter Spencer, head of the MoD’s procurement organisation, blamed the delay on the refusal of the Eurofighter consortium to provide aircraft to test the missiles at an affordable price.
“We were not prepared to accept the price,” Sir Peter said. “We are going to turn this charity into a business.”
The MoD will instead test the Meteor missiles on France’s Rafale fighter jet and Sweden’s Gripen.
So the British taxpayer will pay to have the Meteor AAM integrated with the Rafale and Gripen?
“The Achilles heel of the American military — and it’s nothing that our enemies don’t already know — is fuel,” he said.
“Adm. [Hyman] Rickover [a Navy champion for nuclear-powered ships from the 1940s to 1980s] had us well on our way in the early 1960s to a fleet that didn’t count on foreign countries for its fuel,” Taylor said. “And even back then the country produced more than half its fuel. Now that we produce way less than half of our fuel it just makes abundant sense that one of the ways we can cut our dependence on foreign oil is to build as many surface ships as we can — even some of the smaller ones — that have nuclear power.”
The energy requirements of the entire Department of Defense are miniscule compared to the sum total of consumer demand.
Building nuclear powered surface combatants will do almost nothing to “cut our dendence on foreign oil.”
With regard to power plant size, it’s hard to see a nuclear power plant being smaller than a gas turbine plant as one of the very real advantages of a gas turbine over alternatives is low size and power/weight ratio. True new generation nuclear plant is much more efficient, but it still needs the primary/secondary heat exchangers, steam turbines and associated plant and probably either gearboxes or electric transmission.
It is easy to get data on gas turbines, but there is very little public information on military marine nuclear reactors. So, how do you establish a baseline comparision?
On the other hand, it is not unreasonable to expect that a nuclear powerplant can fit into an oversized 14,000+ ton hull.
The real issue is cost.
The USN built 3 separate, singleton, one-off nuclear powered cruisers and then built a total of 6 series production nuclear propelled cruisers. The USN had been correct to approach nuclear propulsion with such great caution in the 1960s, was correct again to halt production at the end of the 1970s, and was correct again when the last of the nuclear powered cruisers was retired early in the mid-90s.
In all likelihood, nuclear power for surface combatants was just as uneconomic in 1980 as it was in 1960, and remains unaffordable today.
These are drawings I found on some brazilian page.
What do you think?
The Thales brochure seems to indicate that Searchwater 2000AEW can fit into the S-2 Tracker’s existing retractible radome.
Sadly, the Tracker seems to be becoming a rare beast. Does anyone know if any are left in storage in the United States?
Don’t see too many shots of the crane. Looks like they’re having fun :p
It is amazing that this crane took the place of only 3 VLS cells.
In the high threat environment of the cold war, reloading at sea must have seemed to be a valuable capability.
It reminds me of the early claims that gas turbine powered destroyers could literally swap out turbines in the middle of the open ocean.
With a good negociator and as a “export launcher” customer, between 15-20 (15 if there is a large amout of spare and munitions.
Indeed, the definitive Su-35 still hasn’t been “launched.” It has become clear that the original Soviet-era Su-35 will never be produced in numbers, and it remains to be seen how the definitive Su-35 (without canards!) will differ from the standard Su-27/30?
which will make it the biggest carrier after the us super carriers.
Did you forget about Kuznetsov and ex-Varyag?
These Soviet-era 65,000 ton carriers are a great deal longer than CV-F, although the overload French variant is expected to have a significantly larger displacement.
