Why do u think v-22 is good for india?
isn't it cosly?
also no export orders till date.
You are right, it is more costly to procure and also costly to maintain it compared to any other helicopter. However, it is more than a helicopter, because it can be used as a fixed wing aircaft with similar advantages. That's why we should get it for roles, where these advantages outweighs the costs.
The CV-22 is a special forces version, which offers more speed, range, or ceilling than any helicopter, while it will be able to land in the same way. That means, IAF could transport special forces all over the country, be it to the mountains in the north at high altitudes, or an island in the costal area, without the need of an airstrip.
It will have a similar specialisation as the C130Js (a Flir and IFR system, or special avionics), which makes them very useful for penetration roles in the border regions.
For our navy the V-22 could be even more important, because of it's unique features!
It can be used on any type of carrier, be it LHDs, STOBAR or CATOBAR carriers,
again it offers more speed, range, or ceilling, than our current AEW and ASW helicopters, which means a huge capability advantage for our CBGs.
In tanker role it could carry more fuel than a fighter with buddy buddy refuelling.
We could use it for long range transports of cargo or crew, while the carrier remains at sea, which is not possible with any other aircraft in our inventory, because either they lack the range, or they can't land on carriers.
In all these specialised roles, the V-22 would be a great choice, because it can use it's capabilities to the max and offer much performance in return.
Where it doesn't pay out, is the utility role in short to medium ranges, because here it hardly can make use of the advantages and the operational costs would be too high. That's why it was never exported so far, since most countries just needed cheaper helicopters for normal roles. However, it is likely that Israel will be the first export customer, because they want to add it as an aircraft for their special forces.
Quick comparison:
I think India should ask for a deeply-refitted USS Enterprise with Rafale-M jets.
First of all, the US won't offer us a carrier without US fighters. Secondly IN rejected the idea of a nuclear carrier when those rumors about the Kitty Hawk came up, because it's operationally too costly.
Personally I think we are fine till 2020 with our 2 x aircraft carriers and the Vikrant for quiet some time. In the mid to long term I think we should go for at least 2 x LHDs / helicopter carriers and 2 or 3 x IAC 2, because these will be the important once to project the our power beyond the Indian Ocean region. In that case a triple rotation with 1 at sea, 1 in reserver and 1 under maintenance, would give us enough offensive capability at all time.
