Guess what area lies in the middle? Not a coincidence IMHO.

your talking about the philipines? if so, why dont they approach the disputed territories? until they (or any other USN vessel) do that, this is only a largely empty threat/warning/reminder (of course, you will disagree with me, but you cant disprove it). You cant carry over "carrier diplomacy" forever. That kind of thing can backfire on you someday.

kroko, both Stennis and Washington are still in the Pacfic after completing Valiant Shield 2012. their exact position I don't know. the Stennis should be "out-chopping" to the Indian Ocean in the next wek or sooner.

In my opinion yes. They have been operating CVs since 1961. The Russians since 71 with the Kiev. Since the fall of the USSR the Russians have had very limited CV operations where as the Indian CV, INS Viraat, puts to sea regularly.
I think we can divide this into two parts - operating large combat ships & aviation. In both these cases Russia have more experience than either China or India in terms of number of ships operated as well as the number of aircrafts operated.

Indian Navy till now have operated only one large combat ship (carrier) with a maximum displacement of 28,500tons and for a brief period had two carriers in service list from 1987-1997.

To the flight ops, IN have for the past 30years been operating only STOVL and the number of Sea Harriers in service is now around just 11 or 12 airframes, 18 out of the total 30 procured was lost due to accidents. So a proper carrier ops in terms of arrestor recovery is also new to IN. Again in the case of China, none exist. In short we can say that both the navies are starting fresh for STOBAR ops, the only difference is China still does not have a proper fighter to operate from the deck of its carrier.

Actually the Soviets began operating carriers around 1975 - 76 with the Kiev class carriers the first Kiev class carrier was commissioned on 28 december 1975 and before that in 1967 the Soviet navy had its first LHP with the Moskva class.
Agree. Also, if we are to take the capability to operate large ships with aviation, then Russia is far ahead of China or India. India have till now have mainly operated only one carrier and for a brief period had two carriers in service list from 1987-1997. China did not have any. But Russia have operated 2 x Moskava, 4 x Kiev, 1 x Kuznetsov (& 4 x Kirov class) class of ships and definitely more experienced than either of the two in terms of operating large combat ships.

As for the Indians they had operated two Britisch made light carriers from 1961 to 1997 they had the INS Vikrant a CATOBAR carrier which they use to operate Sea Harriers from and from 1987 to present they operate a VSTOL carrier the INS Viraat.
Vikrant was modified with a Ski-jump in 1989 after the retirement of Alize which was the sole user of the catapults after the Sea Harriers replaced Sea Hawks as the main fighter on the deck during 1982-83.

i.e the catapult & arrestor recovery era came to an end by 1982 for Indian Navy. Since then, for nearly 30 years, it has only been STOVL for fighters. From 2013 onwards, it is going to be mainly STOBAR for atleast a decade to come.

I believe India too will have a learning curve with the Vikramaditya but perhabs far less steap than China with the Liaoning. But the effectiveness of the Vikramaditya will be limited because of her design drawbacks compared to the Liaoning.
It will be a learning curve and a similar one for both Liaoning & Vikramaditya, as both navies are going for STOBAR for the first time. But India can be said to have an edge as she have got prior experience with carrier operations. But that is something which China can address with proper training and help from others.

We indian knows how russia works they always under quote and then they raise the price same with aircraft carrier ,nuke sub and now french also learn from russia they want 1 billion more for scorpion sub and our politian is okie with that .
You have a very low opinion about the French.
France do not have to learn anything from Russia, absolutely nothing when it comes to sales & profiting.

That is the question, isn't it? We shall see.

But they are (the Hyugas) vey nice looking vessels and a heck of a ASW asset...not to mention humanitarian. The 22DDH and 24DDH will be just that much more capable. Still looking for consturction photos of the 22DDH.

And I would not be surprised to learn that the new vessels do have the heat tolerance...it also can be added later relatively easily. In addition, the lift capacity will be telling too. That even more so because they are a lot more expensive to fix if they are too light.
I well remember the thickness of the padding on the flight deck of Moskwa when the experimental Freehand VTOL was tested on her deck.
If you want to use V/STOL or STOVL aircraft from the deck of a ship you make the deck able to stand the heat and you add a ski ramp - except of course when politics exclude this, as in USN. The British taught us that. So I think no ski ramp means no jet exhaust proof deck.

The Vikramaditya saga: India now except the asbestos insulation for the boilers.

INS Vikramaditya trials termed successful

The controversial sea trials of the INS Vikramaditya in Russia, initially described as an embarrassing failure, appear to have actually been a success, while propulsion problems developed by the aircraft carrier are not nearly as serious as reported in the media.

After the ship returned to the Sevmash shipyard a week ago the Indian Navy’s overseeing team, who closely monitored the sea trials, came to the conclusion that the ship had overall done extremely well and the programme of tests had been largely fulfilled.

The results of the trials were analysed and remaining work was detailed in a protocol signed by Vice Admiral Nadella Niranjan Kumar, Controller Warship Production and Acquisition (CWPA).

The main conclusion from the trials is that the INS Vikramaditya has stood the test as a full-fledged highly capable aircraft carrier converted from the former hybrid missile-cum-aviation cruiser Admiral Gorshkov. The ship displayed excellent seaworthiness and manoeuvrability and performed flawlessly during aircraft takeoff and landing. It’s sophisticated radio-electronic, navigation and other systems demonstrated high efficiency and reliability.

The malfunctioning of the boilers that occurred during high-speed tests will not require their replacement or removal from the vessel. The problem has been pinned down to insulation lining that is placed between the boiler steel casing and ceramic firebricks. Traditional asbestos lining was not used at the request of Indian specialists and replacement material developed slight deformation when the boilers were run at full power, causing some firebricks to fall out. The Indian side has now agreed to the use of asbestos cardboard.

The boiler problem did not prevent the INS Vikramaditya from completing the trials. Informed sources told The Hindu that Indian Navy officers were particularly impressed by the flight programme. A MiG-29K and a MiG-29KUB 4++ generation fighters performed 41 impeccable take-offs and landings with full arms payload and additional fuel tanks. The combination of Russia and India-made optical and electronic landing systems enabled the Russian pilots in 70 percent of the landings to hook the second out of three arrestor wires, which is considered a perfect result, the sources said.

The 44000-ton vessel also displayed superior manoeuvrability, performing a 360-degree turn at a minimum radius equal to one-and-a-half hull length at a speed of 18 knots.

Apart from the boilers, defects were also detected in some other equipment, such as refrigerators, nitrogen generators and compressors sourced from German, British, Polish and Indian suppliers who had been picked by the Indian side.

Russian shipbuilders have promised to complete all repairs by the beginning of next year, but since pre-delivery trials in the White Sea can resume only in late May, when sea ice melts away, the Vikramaditya will be handed over to the Indian Navy next autumn instead of this December, the sources said.

Its not the politics, but the practice of the USN, and as Jeff stated, the deck can be brought up to any spec desired as illustrated by the Wasp. It is not in the dogma or doctrine of the USN to to build ramps on Catobar carriers since the Catobar system is far more capable, and in my opinion as a pilot, it is far safer to be launched with flying speed, than to jump off the end of the deck at high alpha and low airspeed. I have made most of my departures off of a short sod strip, if the grass is tall, the field is short or soft, a cylinder a little low on compression, the airplane has a cruise prop, the nose gear strut flat or underinflated, same with tires, the airplane over gross, too many or to large a load, too much fuel, or there are obstructions, you will reduce airspeed from best rate to best angle of climb. As you do the pucker factor goes way up, add adverse winds, weather, or darkness and the odds of an accident or incident go way up, so no thanks to a ramp, I'm certain a very high percentage of USN pilots would agree, speed is life, especially off the deck on departure!

HMS Queen Elizabeth aircraft carrier's first crew named

A Middlesbrough woman has become the first crew member of the Royal Navy's largest ever warship - eight years before it comes into service.

Aircraft carrier HMS Queen Elizabeth is the first of two 65,000-tonne ships under construction in Scotland.

Rear Adm Steve Brunton presented Leading Hand Claire Butler with the first "cap tally" band for her hat with the carrier's name on it.

The carrier is not expected to be ready to deploy until at least 2020.

Ms Butler said: "Becoming the first member of the Royal Navy to wear this cap tally is a fantastic honour.

"My main task will be to set up the routines and procedures that will allow the rest of the crew to do their jobs.

Flying trials

"We are all well trained and, as a team, will make sure this warship becomes operational and helps to safeguard the world's oceans."

Six shipyards around the UK are involved in building various parts of the ship, which are ultimately being assembled in Fife.

The ship, which will have 1,600 crew members when fully operational, is expected to head to Portsmouth in 2017, with flying trials beginning in 2018 and deployment possible two years later.

"This isn't just a naval asset, this is a joint asset for the country and the government to use," Rear Adm Brunton said.

"We've already started to build HMS Prince of Wales and many of the ship's systems are being tested ashore ready to be brought on board."

The ships are being delivered by the Aircraft Carrier Alliance, a partnership between BAE Systems, Thales UK, Babcock and the MoD.

Comments: Smart move by the Indian Navy. Get the INS Vikramaditya into service since everything else performed well during sea trials and get Mig-29Ks flying off her deck.

So, in essence, they are going to accept her and do relatively minor fixes by adding the asbestos.

This will get them back much closer to their original time line.

It will be interesting to see what they announce that time line as. That will tell you how much real work has to actually be done, despite such press releases.
