The major modifications were to allow "Admiral Gorshkov" to operate as a STOBAR aircraft carrier in Indian service, as opposed to the STOVL configuration the ship was built as. This involved removal of all the armament, including the P-500 "Bazalt" cruise missile launchers and the four Antey Kinzhal surface-to-air missile bins fitted on ship's bow, to make way for a 14.3°, full-width ski-jump. The 20-ton capacity aircraft lift beside the ship's island superstructure was unchanged, but the aft lift was enlarged and its lift capacity increased to 30 tons. For STOBAR operations, three 30 m arrestor wires and three restraining gears on the stern of the angled deck were fitted. Sponsons were installed to increase the area of the flight deck, to allow the ski-jump to be fitted, for strengthening of arresting gear and runway area, and to lengthen the after end, which allowed an increase to the length of the landing strip aft of the arresting gear. 234 new hull sections were installed to achieve the desired shape, and the total steel added to carry out these modifications amounted to 2500 tons.
