Modernisation is a constant process. The Indian Navy has acquired INS Vikramaditya from Russia. It is a modified Kiev-class aircraft carrier which entered into service with the Indian Navy in 2013. Originally built as Baku and commissioned in 1987, the carrier served with the Soviet Navy and later with the Russian Navy (as Admiral Gorshkov) before being decommissioned in 1996. She was commissioned on 16 November 2013 at a ceremony held at Severodvinsk, Russia. On 14 June 2014, the Prime Minister of India formally inducted INS Vikramaditya into the Indian Navy and dedicated her to the nation. In addition, Jalashwa – Landing Platform Dock, Shivalik Class – Stealth Guided Missile Frigates, Kolkata Class – Stealth Guided Missile Destroyers, Arihant Class – Ballistic Missile Nuclear Submarine and Sumitra Class – Offshore Patrol Vessel – new classes of ships have been commissioned in recent times. To replace the aging MiG-29K aircraft of the fleet of the aircraft carriers, 26 Rafale-M aircraft are being inducted shortly.
