http://idrw.org/?p=2452 The DRDO has rescheduled the test-firing of submarine launched ballistic missile ( SLBM) K-15 to January 31. It was supposed to be test-fired from an underwater platform off the Vishakhapatnam coast on January 20. â€œThe test was first scheduled on January 16, but was postponed to January 20. Now it has again been rescheduled to January 31 due to delay in arrangements. It is a coordinated exercise of both land and Navy personnel,â€ a source said. â€œIndia can join the league of five nations, Russia, US, France, Britain and China, with the successful launch of the K-15 missile. These countries already possess advanced missiles that can be launched from a submarine,â€ sources said. The indigenously developed K-15 or the B-05 missile are 10 metres in length, one metre in diameter and weighs ten tonnes with a strike range of around 700 km. This missile uses solid propellant and carries a conventional payload of about 500 kg to one tone and also be fitted with a tactical nuclear warhead. â€œThe missile is ready for the test. But preparation is on for locating the Pontoon (replica of a submarine) inside the sea. The tracking machineries and technical equipment have been shifted from the integrated test range to Vishakhapatnam,â€ the source added. The K-15 missile has been tested at least six times and is in serial production. The missile was initially test-fired under the name of Sagarika project. While its launching was recorded partial success twice, the rest were claimed as â€œsuccessful trialsâ€ by the DRDO. The missile, which can be compared with the Tomahawk missile of US, is Indiaâ€™s response to Pakistanâ€™s Babur missile. The source further said that the Navy has reportedly been insisting for the test of K-15â€²s cruise variant as it is hard to be obstructed and has pinpoint accuracy. â€œCruise missiles are more difficult to detect and hence less vulnerable to anti-missile defence, which can track and destroy ballistic missiles with comparative ease,â€ a defence scientist said. â€œBesides, the K-15 missile, India has another missile which can also be launched from a submarine. In a joint collaboration with Russia, a submarine-launched version of BrahMos cruise missile has been developed,â€ he added.
