Defence Minister Peter Luff discusses the F-35 and carrier strike capability

Does the UK need an aircraft carrier? Does carrier strike represent a relevant strategic capability considering Britain’s likely role and influence in world affairs over the next 50 years?

There is growing debate among politicians, the military, historians and analysts about whether or not carrier strike capability is justifiable on the back of the significant cost of building two Queen Elizabeth class carriers and acquiring the new fleet of fifth generation fighters that they will accommodate.

I posed this question to Peter Luff, the Minister responsible for defence procurement at the MOD, during an interview recently. He is firmly on the side of the exponents.

“It would be a very big decision for the UK to abandon carrier strike as one of its key capabilities to project power around the world,” Luff said.

Answer in a word?

Falklands.

They never know when such a crisis will arise and at the time it is occurring, it is too late to build the resource necessary to protect them... and thus their posessions and citizens will be lost.

England is an island nation, with far flung interests and resource needs, and far flung parts of its common wealth. To not have the power to protect them is to ultimately not have them. Pretty straight forward.

Found this interesting:
“We had understood that the carriers were easily adaptable to take the ‘cats and traps’ system. That probably was true in their early design life, say ten years ago … but it was just more expensive to install the equipment in the carriers than we had been told at the time of the SDSR [in 2010].”

Just leave it behind

India would be better off leaving the Vikramaditya behind in Russia and save her self 2 billion $, not to mention the billions to come for the years to operate and maintain this ship. I have been aware of this project for some time but has only taken interest recently because of the pending sea trial. This aircraft carrier is a turkey and has inherited fatal flaws from the Admiral Gorshkov. First this aircraft carrier can only launch one plane at a time. This is because the oversized island is not placed all the way to the side but somewhere 3/4 of the ships beam. This has eaten up a lot of the space on the flight deck so leaving little room for flight ops. The second problem is that the elevators are also not located on the side but are also in the middle of the flight deck. There are 2 elevators a 20000 ton elevator in the back of the ship in front of the "parking lot" behind the island and the main elevator of 30000 ton were the MiG-29's come up from the hanger deck is placed beside the island right in the center and even stretches on to the runway were the aircrafts land. This means that if there are flight ops then the MiG's in the hanger cannot come up and if the MiG's were to come up flight ops has to be suspended. And if the main hanger elevator ever get stuck than you have to hope that they are close enough to the coast so that the MiG's can land in a airbase on land. There is virtuelly no room between the island and the runway leaving little to no room to work on the aircrafts on the flight deck. I don't know if the Russians retrofitted a jet blast deflector on the deck because there wasn't one on the Admiral Gorshkov. If not it will be interesting to know how far people will need to stand back on the cramp flight deck not to get burned by the 1300°C jet exhaust. The aircraft carrier only has 3 arrester wires because there is no room for the fourth one. And from the photo's we have seen from the inside of the ship it seems to me that the Russians spend the past 8 years installing new equipment rather then new technology. Those control panels looks brand new but also look like they were build in the Soviet Union in the 1970's.
Too late to leave it behind...and the Russians would not accept that, they will want full payment.

The flaws you list are true...but they are not fatal, just limiting.

They will be able to launch from two positions, sequentially after one another rather rapidly.

Very few carriers outside of the United States ever launch two aircraft simultaneously, and it does not happen often even with the US...but it can and does happen, and if needed the four cats can put a lot of aircraft in the air very quicly.

But the Vikramaditya is going to be a large enhancement and improvement over the Viraat and the earlier Indian Carriers. With the Mig-29Ks and the parking that is available in front of and behind the Island, they will be able to conduct as good of air operations as any carrier outside of the Russian, the Chinese, the French, the new UK carriers, and the US.

IMHO, that will suffice for them until the get their 1st and 2nd indegenous carriers in place.

Overall, that is a really nice upgrade and enhancement to the former Soviet/Russian Gorshkov...which was the last of the Kiev class commissioned in 1987 and so has a lot of years left on its hull. For 2.3 billion (which wa a lot higher than they first wanted) they got that 45,000 ton carrier and a whole wing of Mig-29K aircraft and a lot of training and all the documentation. Even at that price,that's not a bad deal if it works as advertised.

Re: Does india really need aircraft carriers

To answer that question we'll have to know what India's naval strategy is. To the best of my knowledge nobody in the CCNS knows and if they do they aren't telling anybody.

You are right that it's now too late for the Indians to back out of this deal for financial, political and legal reasons. At least the Indians will have their domestic carriers to look forward to that would have more credibility than this one. However i do believe that the flaws on this carrier are fatal. To begin with there is very little space between the island and the runway and i think you're artist rendition of the carrier maybe too optimistic about how much space there will be on the deck. Which leaves virtually no space for the deck crew to work on the aircrafts. They have two choices. Either they can work on the runway itself which means all sorts of objects could fall on the runway and can cause serious accidents during landing. Or they can move their operations on to the space infront of the island robbing themselves of precious parking space and it could be a hazardous and hair razing experience both for the deck crews and the pilots to have planes take off and people working on the jets in such close proximity.

But the REAL problem of this carrier is the 30 ton main elevator. Any malfunction or poor timing in the use of this elevator could halt all flight ops at best or cause a catastrophic accident at worse. Because this elevator is located in the center of the carrier even on to the runway anything going wrong here means that the planes in the hanger cannot come up and even worse the planes in the air cannot land. The second elevator of 20 tons cannot take the weight or size of the MiG-29's so the 30 ton elevator is the only way in and out for the MiG-29's. Of course a jammed elevator is a serious problem on board any carrier but it does not cause the suspension of all flight ops or have the potential to cause a catastrophy on the ship like on the Vikramaditya.

Anyway i got a translation here of a blog entry from a former worker on the Vikramaditya.

I have worked on this project for 6 years with hydraulics. The negative points are, for example, one of its parts, PTG 30/2 (hydraulic cable lift), which is a large aircraft lift located in the middle of the deck. An airplane delivery on deck takes no more than 5 minutes, and lifting takes no more than 2 minutes, including towing and unfastening of the aircraft. It can lift up to 30 tons. It will be one of the starting positions for the airplane, and when operating it, one cannot takeoff or land (this disadvantage has been inherited from Gorshkov and is there to stay). In the place of contact with aircraft landing deck, it's a great location for an arms cellar with a lift lid, and fight operations. Why they have this cellar in its current configuration is not very clear. It is very small, judging by the number of racks, can hold anti-aircraft shells, but only a dozen (large) bombs. At the time when I had left my job, the user of the hydraulics were not able to manually control it in case of an emergency (which includes the valve for fire, heeling, trimming, bilge, fuel, in general almost all airplane related systems and their issues, with the exception of special systems, like GEU). The designer of the ship placed the stern bypass spool valves backwards. I wrote them angry letters for 2 months about the potentially dangerous situation, but they were probably smarter, and left it as it is. There are only 3 brake wire ropes, and not 4 as in Kuznetsov, due to the fact that the hydraulic brake machine is not sharp, and then, there are only 3, because there isn't enough space for the 4th one. Indian pilots will not hold this in high regard. Does the ship have the proper anchoring device? I just do not know; and the most funny things is that even the designers of the ship are not sure. Moreover, the iron parts came from the northeast, that had 70% accuracy of the drawings. We were certainly blinded to the working scheme of it although it was in the factory. I don't know how it will work. There was a similar situation with the SPU boats. One small amount of idiocy out there is a block hydraulic hoist rope machine in one room and this unit is powered by a backup pump station in another room. Why are they in different rooms? I certainly do not remember everything now, but this ship is one big fun, like a lot of different things, but these little things add up to a total ass, which is mainly the fault of the designers and the factory in Nikolaev (only factory in Nikolaev can, given one drawing, produce three different objects). In short we do not need this. Indians for the first time came for training, but we no longer need this; we have already had one of these.

So I still think we do not need this. Look at Kuznetsov; the aviation-wing is in addition to assault and anti-aircraft weapons, plus two full lifts located on the starboard side, and stay away from sites, so that it allows, at least as it is, to more or less actively carry out the rotation of the aviation-wing from the hangar to flight and back. In general, the shortcoming is that there are no assault and anti-aircraft weapons, but only the aviation-wing. With all of Vikramaditya's assault weapons dismantled, this is a pure carrier (added: Gorshkov was a Tactical Aviation Cruiser), and its only weapons are the planes, but then one lift is for aircraft (the second PTH 20/3 for helicopters has the entire width of about 5 meters, where even a MiG with folded wings will not fit). The lift is very badly positioned to the left (added: port side) of superstructure (added: island) down to the hangar. This forms a gaping hole in the deck. There is certainly room to run the aircraft with this hole because there still is five meters left, but I think pilots will not like to take chances taking off with such a short span. In general, working with the lift imposes restrictions on flights, and flights impose restrictions on the operation of the lift. This is the first significant downside of the project. Further, Vikramaditya has the same deficiency as that of Kuznetsov, the trampoline (ski-jump), and just about a decent starting position that it is less likely it will be possible to take off with fuel and weapons; and the add-on (blast-shield), which is located near the lift will likely limit at the maximum takeoff weight (which means less fuel and weapons), and the airplanes will fly nearly twice as less (added: about half the range?). Now, remove the add-on, and you don't have the blast-shield. As I wrote just 3 arresting gears, smaller flight deck in general, etc. In general, it's very difficult to fully use the aircraft. I believe that the aircraft carrier, whence, it is difficult to use the aircraft, is not needed. This is all purely IN MY HUMBLE OPINION, and of course, no one is prohibited to think differently.
