The aircraft carrier INS Vikramaditya is yet to delivered to the Indian Navy. The ship was put to sea for trials from June to September 2012. During the sea trials over 108 days, the main propulsion plant could not complete the 'full power trials' due to defects encountered on 'boiler furnace brickwork' at higher speeds.
The aircraft carrier commissioning in the Indian Navy is now scheduled in the last quarter of 2013.
The final cost of the Project agreed upon in March 2010 is 2.3 billion USD. The reason for increase from the initial cost decided in January 2004 was due to increase in the scope of the repair and modernization work.
