Philip, I had gone through your earlier posts

. Indeed its an indeppth study ranging from battle cruisers-->mini subs. Also I had a brief chat with my dear friends (of CBG support group!!! I presume

). The fact is any defensive/offensive network should be based on pragmatism. I elaborate a little more:
Some facts: 1. The first squadron of Tejs will be based in south
2. Vikramaditya with a full/ upto 70% gown CBG will come by 2015 (must be done)
3. Vikrant should be ready by 2015(extend one more year) and the aircraft in hand will be Mig 29K, Naval Tejas
4. Fasttrack acquisition of subs underway and we may see AIP Scorpene by 2015--16.
What my gut feeling is that the lone carrier Vikramaditya (within 2020 period) will be covering a medium zone in Indian Ocean, Bay of Bengal under coverage by land based aircrafts. Home grown LCA with a range of 900 km and limited Su30 Mk cover will be there. So by no means we can extend beyond Andaman. The two CBGs will take around 10 years from now on to grow in full strength.
The urgency is to snap Sino-Pak nexus building around India and the chickens neck is South china sea. All the coastal powers there are unhappy with China for their aggressiveness. Current situation is:
1. Chin is extending its influence but with two thorrns in the neck: Formosa and NK. In Formosa its engaged in shadow war and in NK its a mask war.
2. CHinese airforce has Su 27s at reserve but may/must not risk it out in face of USN umbrella (which is steadily waning)
3. The lone CBG of China is in development stage and most alarming is their stress on sub activities.
To encounter INS has to have
I. A solid air arm (comprising of Harrier, Naval Tejas, Mig 29 K, Jaguar maritime, Su 30 Maritime.
INS may try out FA/18 option with Performance
Maximum speed: Mach 1.8 (1,190 mph, 1,915 km/h) at 40,000 ft (12,190 m)
Range: 1,089 nmi (1,250 miles, 2,000 km) with only two AIM-9s
Combat radius: 400 nmi (460 mi, 740 km) on air-air mission
Ferry range: 1,800 nmi (2,070 mi, 3,330 km)
Service ceiling: 50,000 ft (15,240 m)
Rate of climb: 50,000 ft/min (254 m/s)
Wing loading: 93 lb/ft² (454 kg/m²)
Thrust/weight: 0.96
A perfect medium altitude level fighter (40k ft.) with a good niche of engaging ground targets.
(infact I was surprised to see FA/18 in MMRCA while it is a perfect choice to complete a triad of INS air arm i.e. Maritime Su30 (Top cover ~ 60 k Ft), FA/18 (medium cover+attack ~ 40 k Ft) and lastly TU 23 M (low altitude strategic bomber).
You may very well ask my intention i.e. am I trying to convert INS--> IAF. The answer is No.
A handfull (5-->6 pcs of Tu22M), 60 odd numbers of FA/18 and maritime Su 30 good enough for another couple of decades. Infact I read reports of extending the numbers by another 60 in MMRCA. Why not the extension be done in favour of INS. Also advantageous will be addtion of FA/18 on future carriers of INS.
With this much air cover INS stands chance against possible intrusion of PLAN or even to take offesive maneavre over south china sea. Any Navy (take example of USN) if wants to make its presence felt always stress on air arm. Addition of 6 odd nos. of Tu22M and 60 odd FA/18 (hope naval LCA will come by then for carrier) stands as a check on chess board in Indian Ocean. I may be wrong too!! but just as a hunch I put my words.
