Re: Su-30: News and Discussion - August 9, 2014

I think our replacement plan should be as follows:-

Mig21 to be replaced by LCA MK 1 & LCA MK1A
MIG 29 & Mirage 2000 by LCA MK 2
Jaguars should be replaced by additional Su30MKI as both Ghatak, AMCA are too far away & Rafales are costly.

I think there is no point being impatient. It would be ok if no LCA roles out for first 6 months and then 12 LCA roll out in next 6 months. We should start looking at the calendar only after July 2018. Personally I would be good with 8 LCA is last four months, and will be calm till December 2018.

To complete 40 LCA, it will take another 4 years for HAL @ 6 to 10 per annum. For 83 LCA, I assume rate will pick upto 16 per annum ie another 5 years, though 24 per annum is preferable. For next 200 Mk2, it may be another 8 years even @ 36 per annum, so 48 per annum is required.
