India's first indigenous aircraft carrier, the new Vikrant, won't be commissioned before 2017, Indian Navy chief Admiral Nirmal Verma said yesterday, indicating a further two year delay from the previously known time-frame. The Admiral explained that over and above existing delays, there had been serious problems in the installation of gearboxes, coupled with an unfortunate road accident from Pune to Kochi where a truck transporting generators for the ship turned turtle, forcing the shipbuilders to send the equipment back to the OEM for inspection and repair.
