RS. 30,000 Crore is 300 Billion Rupees or about $6.7 Billion at today's exchange rate.
Seems a reasonable price,though it is bound to fluctuate(to the higher end) by the time it is 2010+.Really depends on what the IN wants.Is it just going to standard 4,000 tonne frigates or the European concept of 'Frigates' which are really destroyers in all things.It will most probably feature the new Israeli Indian Barak-2 medium/long-range SAM & MF-STAR radar system & the European anti-sub equipment.
