I don't really understand why and how Vikramaditya was planned with a long range SAM system.
The heavy SAMs and the associated radars/equipment could easily be installed on an cheaper escorting destroyer, and it would be better as launching SAMs would not interfere with flight operations, plus the radars would have a better view.
So additional aircraft/fuel/weapons could be carried on the carrier, which maximises the capability of that single flightdeck.
Or they could fit more short-range air defences which do benefit from being pointed directly at incoming missiles.
The Indians wanted to have a full measure of defenses for their carriers (they are planning the same for the Virkant), so they want to include LR, MR and SR AAW capabilities to give those carriers as much protection as possible.
They also have escorts that have the LR (ultimately), MR, and SR AAW capabilities as well in the Kolkatas, Delhis, Shivaliks, and Talwar class vessels as escorts for the carriers.
As to anit-missile operations impeding flight operations...they need not.
Ideally you do not want to be launching or recovering aircraft in the middile of a shooting war with missiles. It would be a rare condition when things were so dire, with an incoming strike against a full deck of aircraft, that you would be launching them as such an engagement took place.
With the proper size and placement of sponsons around the flight deck, missile launches can occur completely on the peripheral of the flight deck, with none occurring directly off the bow where aircraft would launch.
The Indians have desgned their carriers for this enventuality. The biggest problems thay are having is getting the LR missile procured to accomplish this.
From my perspective, however, they would have been better served to have four 20 or 30mmm CIWS, and four SR-MR missile launchers like RAMs or FN-3000L, each with 20+ missiles, and that would have been adequate for the carrier itself.
Flt III Burke's most important improvement is the bigger AMDR-S radar. The size of the radar is a result of the ABM requirement. Since the AMDR is even bigger than the current SPY, it is definitely not going to be placed higher. For horizon search,
Burke relies on a lightweight rotating AN/SPQ-9B.
So difference mission emphasis result in different designs choices. European AAW are primarily designed to defend against sea-skimming missiles, while Burke's primary mission is ABM.
Actually, BMD is not the Burke's primary mission. It is a part of it's primary mission, which is fleet air defense. But the Burke's are also true multi-mission capable DDGs.
As I say, their primary mission has been, and will remain fleet air defense. Primarily for carrier groups, but also for ARGS as required. And in that role they will also provide ASW defense, and ASM attack capabilities as required.
It is true, because of the flexibility of the VLS, and with the upgrades in SPY and with the IIIs in the new radar, that some of them are being purpose loaded out for the ABM role...and ultimately any of them will be able to as they get the upgrades. But those that will be purposed primarily for BMD will represent a small precentage of the whole, and those vessels are likely to rotate through that assignment.
Remember, in today's world, BMD also applies to fleet air defense, so most of them that are performing the fleet defense role for a CSG that is in any way near such ASBM threats, will have some BMD missiles as well.
But this is all off topic for the Indian thread, so let's get back to that, shall we?
