Know about INS Kolkata, victim of another naval mishap

New Delhi: In another twist to the ongoing mishaps in Indian Navy , another naval ship INS Kolkata, under construction, met with an accident on Friday. A commander rank officer of the Kolkata class destroyer was killed in the mishap. INS Kolkata is the lead ship of the Kolkata-class guided-missile destroyers. She was constructed at Mazagon Dock Limited, and is currently undergoing sea trials.The naval ship has not yet been commissioned in Indian Navy. Officially now called Yard 701, INS Kolkara is the most modern destroyer of India, and is now at the Bombay Port Trust undergoing trials. INS Kolkata is the lead ship in the guided class destroyers. The other two would be INS Kochi and INS Chennai. Construction of three Kolkata-class ships was sanctioned by the Government of India in May 2000, and steel for the lead ship was cut in March 2003. Construction began in September 2003 at Mazagon Docks, Mumbai, with an initial expectation that the first of the class would be handed over to the navy by 2010. However, since then the Kolkata-class has suffered consecutive delays, slow construction procedures and technical problems which will now see the first of the class now enter service during early 2014. The delays in the construction programme have been attributed to - persistent design changes made by the Indian Navy to incorporate new weapons systems and sensors, failure by a Ukrainian shipyard to deliver the ship's propellers and shafts and the contract later being awarded to a Russian firm. And finally the delay in the delivery of the Barak 8 anti-air missiles, which are still in the final stages of completion with Israel Aerospace Industries and the Defence Research and Development Organisation. The Kolkata-class are the largest destroyers ever to be constructed at Mazagon Docks, and as of 2013, all three ships of the class have been launched and are being fitted out. Technical problems were found during the sea trials of the lead ship Kolkata, which delayed the project by six months to early 2014.
