Sources said even though the final price of Gorshkov was still to be worked out, it will cost the Indian exchequer a minimum of $2.2 billion. Already, the work to be done on the ship has been identified between the two sides and construction should begin in earnest after the purchase agreement is sealed. The ship will now be constructed by 2010, sea trial and weapons should be over by 2011 and the transfer to the Indian Navy the next year. When commissioned into the Indian Navy as INS Vikramaditya, it would replace INS Viraat, India’s sole aircraft carrier that will be decommissioned by 2010. When delivered the ship would be carrying 12 MiG-29 K fighters, 4 dual-seat MiG-29 KUB, six Kamov-27, Kamov 31 helicopters and will have a life span of 30 years.
