K-6 (missile)


K-6 is an intercontinental submarine-launched ballistic missile being developed by the Defence Research and Development Organisation of India. The missile has a planned range of around 6,000 kilometres.

Requirement

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 kilometers 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 Naval Systems Laboratory of DRDO, with a completion target of less than ten years.

Description

The K-6 is an intercontinental submarine-launched ballistic missile. It is a three-stage missile and is solid fuelled. It is planned to armed with multiple independently targetable reentry vehicles and will have a range of around 6,000 kilometres with a three-tonne payload. It has a planned length of over 12 meters and a diameter of over 2 meters.

Development

The K-6 is being developed by the Advanced Naval Systems Laboratory of the Defence Research and Development Organisation since 2017. Testing of the K-5 missile will assist in developing the K-6.
