Very true. Specially the North-East is connected with rest of India through a very narrow corridor. Link with Ladakh is also very fragile.So it is important to deploy a researve force there so that any Chinese invasion can be countered even without reinforcement from other parts. The troops deployed there must be well acquinted with the terrain and also with the probable strategy that would be adopted in case of emergency.
Incase of a two front war our strategy will be to get rid of Pakistan as soon as possible (specially there air-force and navy) while holding China at bay. India is increasing the number of Su-30 MKI. Along with it we need long range aircrafts that can carry good load of ammunitions to carrry on attack on Pak ground targets.
Government has taken the very prudent decision of deploying Su-30 MKI in Andamaan. Units of air-defence systems must be deployed in Andamaan to insulate this base from any Chinese attack. Basically Andamaan is a God gifted natural and unsinkable aircraft carrier for India and we have to make full use of it to prevent entrance of Chinese armada in Indian Ocean. (Because in case of a war we need to cut Chinese oil supply and and any assistance to Pakistan via sea rute.) Andamaan must host ASW copters and planes to do the job effectively. Long range strike capability of Sukhoi aircrafts, ASW capabilities , ability to lunch cruise missiles like Brahmos from air-earth-sea and last but not the least-a good control and communication system will be mandatary to keep PLAAN war ships out side Indian Ocean.
We are including 6 Phalcon AEW&C but we need to include our indigenous systems too(even if they are inferior to Phalcons) for more secured vigilance. We need to give thrust in projects like Akash, Barak-2 and if posible to include more sophistacated SPYDER system to guard our cities and other strategic points.
Hope within next couple of years Agni -III will be deployed which has the capability to target farther areas in China thus providing a fitting reply to Chinese missiles.
Fotunately, there are lot of projects undertaken to be in a position to effectively counter both of our neighbours in necessity. Inclusion of Sukhoi PAKFA/FGFA, MCA, mark-2 versions of LCA, MMRCA aircrafts, Scorpene and other 6 Submarines, the aircraft carriers , 6 ATVs and leased SSN (Advance Akula-II) , joint ventures with israel to develop barak-2 - a long list is there. Only we have to ensure they would come up in time. Private players like Tata, Mahindra, Godrej, L&T are comeing in defence industry, a lot of Jvs with global majors like Boeing, Dassualt, Saab -we can expect our defence industry to be more matured and more efficient in coming days. So if every thing goes on properly we will not onl leave Pakistan much behind we can match China too (atleast in our den) and also a qualititive advantage over them. So keep fingers crossed.....
