The Defence Research and Development Organisation (DRDO) successfully test-fired a 3,500-km range submarine-launched ballistic missile, K-4
- K-4 is one of the two underwater missiles that were being developed by DRDO. The other one is the over 700 kilometre strike range BO-5 missile.
- The missile has been tested several times earlier as part of developmental trials to validate different parameters.
- Once inducted, these missiles will be the mainstay of the Arihant class of indigenous ballistic missile nuclear submarines and will give India the stand-off capability to launch nuclear weapons submerged in Indian waters.
- INS Arihant, the first and only operational SSBN, is armed with K-15 Sagarika missiles with a range of 750 km.
Important Info :
- The test was conducted from a submerged pontoon off the Visakhapatnam coast. A pontoon simulates the situation of a launch from a submarine.
- According to DRDO, there are very few countries which have managed to achieve this technological breakthrough with India’s Circular Error Probability (CEP) is much more sophisticated than Chinese missiles. The CEP determines the accuracy of a missile. The lower the CEP, the more accurate the missile is.
- SSBNis the US Navy hull classification symbol for a nuclear-powered, ballistic missile-carrying submarine. The SS denotes “submarine” or “submersible”, the B denotes “ballistic missile,” and the N denotes “nuclear powered.”
