INS Viraat
[8] INS Viraat had a 12° ski jump to operate the Sea Harrier along with a reinforced flight deck, and 1.2 inches (3 cm) of armour over the magazines and machinery spaces.The vessel retained commando transport capability for up to 750 troops and carried four LCVP landing craft in the aft section.[15][16] New fire control equipment, navigation radars, improved NBC protection, and deck landing aids were installed in this refit.[18] The allegation has been refuted by a retired Indian Navy officer, Commodore Ajay Chitnis, who was involved in planning former Prime Minister Rajiv Gandhi's 1987 Lakshadweep trip.The ship underwent a fourth refit in Indian service from January to August 2009 at Cochin Shipyard, Kochi.[22][23] On 12 July 2011, the ship arrived at Cochin shipyard for a short refit scheduled to be completed in two months and it was repainted.[27] By 2013, Viraat's age and cost of maintenance prompted the navy to begin the process to obtain Defence Ministry clearance for her decommissioning;[28] in December 2014, a review board was established to determine the ship's continued service life.[30] At Kochi, she underwent a month-long deactivation in preparation for decommissioning; during this period, her boilers, engines, propellers and rudders were removed.[38][39] On 1 November 2018 the Maharashtra cabinet approved the conversion of Viraat into India's first moored maritime museum and marine adventure centre, to be located near Nivati, Sindhudurg district.Shree Ram Shipping offered to sell Viraat to Envitech for ₹100 crore (US$12 million), provided the firm receive the clearances and assume all cost and risk.
