The IN in my view was essentially an orphan arm till it got its act together( in a manner of speaking). Its currently on route to become possibly a more potent Navy than that of Russia(if it can sort out its Submarine issues). The Fly and Die concept relies on the Air denial capability of its surface and aerial assets. However, while the Mig-29s have the potential to provide a certain air superiority element, there is a need for longer ranged SAMs on board the capital ships.
At this point the Barak-8 provides a capability similar to the ASTER-15 but what is needed is the ability to engage targets out to a 100km radius(or more). In essence, an Indian Marine landing force should have protection from air attacks well into the shores.
The Olivers had their Launch systems removed due to the non-availability of SM-1 systems.
Yet, this requires that the precise position of these system be known. That too is a sorting job that may not prevent a launch of the missile. In addition, the Chinese were advertising a C-803 based shore system with the ability to receive off board targeting.. say from a sensor system such as the ZDK-03.
That offers a rather unique tactical capability in having SSM systems sitting essentially silent electronically before being given coordinates to launch.
The FAD is my designation, NOT EVEN THE IN CAN STEAL THAT FROM ME!
I disagree on the Aster-15 and Barak-8 comparison though.
First and foremost the range difference is more than double, secondly a certain quantum of speed was sacrificed for lateral acceleration (the Aster's 12Gs to the Barak's 80Gs, for immediate and near instantaneous orientation against maneuverable targets in conjunction with the 2 way data link/mf-star and active seeker, most high speed in-bounds even with dual pulse motors will be limited in their end phase maneuvering lest it be a liquid fueled in-bound). With the MF-STAR the Israelis are counting on it to take down even high speed ballistic in-bounds in a TBM role (although its the lack of a 3D L-band VSR on our ships which is the issue, not the performance of the SAM).
Where the Barak-8 has issue is in absolute slant range, which is prospectively meant to be covered by the ER variant (with an additional booster).
ANYWAY:-
The FAD is actually meant to be employed with a bigger carrier and fixed wing AEW assets organic to the CBG rather than shore based, we are talking ETOS of 5-6 hours and multiple birds per carrier for round the clock AEW and ISAR for the CBG and BARCAP. That will fall on the shoulders of the men who will man the prospective INS Vishaal.
Without said fixed wing AEW assets the current CBG with the Kamov Okoeye AEW is not capable of enforcing something akin to FAD and will actually have to maintain some distance from Pakistan's territorial waters.
The current MDL tender for a scale model of the 15B calls for 8*8 cell VLUs for SAMs along with 16 cells for AShMs or LAMs, no news on a high performance L-band 3D VSR although the "defence experts" are betting on the RAN-40L with TATA hooking up with THALES NEDERLANDS to offer the SMART-L from the Type-45. Lets see how that pans out (recent sat images posted on this site itself show that construction is getting along well, dunno if we will slip on the outfitting as we so often do).
Still, at the end of the day, no organic fixed wing AEW = NO FAD.
