On 1 June 2010, "The Times of India" reported a naval officer saying: "With India earlier this year agreeing to the revised refit cost of $2.33 billion for "Gorshkov" after three years of bitter wrangling since the earlier agreement inked in January 2004 had earmarked only $974 million for it, Russia has appointed a high-level apex committee to oversee the work on the carrier". The ship was to go for harbour trials by early 2011 to ensure it could be handed over to India by December 2012 or so. Dock trials began on 1 March 2011. The focus of these trials was on the main power generation units and the radio-electronic armament systems, manufactured in India. Indian Navy personnel began training on "Vikramaditya" in April 2011. On 19 April 2012, it was announced that all internal systems were functioning, and the ship was entirely self-contained. Measurement of the ship's magnetic field and centre of gravity were performed before sea trials began.
