Passage: Vikramaditya has been designed as a STOBAR carrier capable of operating both conventional fixed-wing aircraft and helicopters, with up to 34 aircraft capable of being accommodated. Its primary embarked aircraft type is the Mikoyan MiG-29K, a navalised version of the Mikoyan MiG-29M. The MiG-29K is an advanced, all weather multi-role fighter capable of undertaking both the fleet air defence, low level strike and anti-shipping roles. The primary ASW platform is the venerable Westland Sea King, while AEW is undertaken by the Kamov Ka-31. Carriage ranges given for the ship seem to converge around 16–24 MiG-29K and 10 Kamov Ka-31 or Dhruv helicopters; however Vikramaditya is not capable of operating fixed-wing AEW aircraft owing to her configuration as a STOBAR carrier. Utility and plane guard duties are undertaken by the HAL Chetak (or HAL Dhruv).
