K-6 (missile)
K-6 is an intercontinental submarine-launched ballistic missile under development by the Defence Research and Development Organisation of India. The missile has a planned range of more than 8000 Kilometres.
History
The development of the K-6 missile, with a range of 6,000 km, was initially reported in early 2017.Admiral Arun Prakash wrote in 2018 that the missile range of the Arihant-class submarines is not sufficient to target potential adversaries of India; a missile with a range of around 6,000-8,000 kilometres would be required for this task to be performed by a submarine patrolling in a "safe haven".
When the missile payload limitations of the Arihant-class were realised, India began developing the S5-class of submarines and the K-6 ballistic missiles. The developmental work for these missiles started in February 2017 at the Advanced Systems Laboratory of the Defence Research and Development Organisation, with a completion target of less than ten years.
