Kalvari, Indian Navy's first indigenous Scorpene-class submarine, has hit the sea for trials! The submarine sailed out under her own propulsion for the first sea trial, off the Mumbai coast on May 1.
A number of number of preliminary tests on the propulsion system, auxiliary equipment and systems, navigation aids, communication equipment and steering gear, various standard operating procedures were also validated for this new class of submarines. The submarine then returned to harbor in the evening.
During the next few months, the submarine will undergo a barrage of sea trials, including surface trials, diving trials, weapon trials, noise trials etc. which would test the submarine to the extremes of its intended operating envelop.
