On Saturday, when the INS Kolkata is commissioned into the Navy by the Prime Minister, the biggest and most powerful destroyer built by India will be missing basic weaponry. It went into construction in 2003, but 11 years later, it is still not battle-worthy. One of its primary weapons, a long-range Israel-built surface-to-air missile called the Barak 8 is still being developed, which means the INS Kolkata is vulnerable to attacks from enemy missiles.
