The Sagarika/K-15 missile is the SLBM version of the land-based Shaurya missile.With a shorter range than K-4 missiles it is to be integrated with Arihant class submarine concurrently developed for the use of Indian Navy.

Sagarika/K-15 was developed at the DRDO’s missile complex in Hyderabad. The complex consists of the Defence Research and Development Laboratory (DRDL), the Advanced Systems Laboratory (ASL) and the Research Centre, Imarat (RCI).
DRDL designed and developed the missile, while the ASL provided the motors and propulsion systems. The RCI’s contribution was in avionics, including control and guidance systems and inertial navigation systems.

Medium range K-15 ballistic missile has a range between 700  km to 1,500 km with varying payload. This will also get help from Indian Regional Navigation Satellite System (IRNSS) to ensure guaranteed national access to precision navigation.These will enable high accuracy required for precision strike. The last developmental test of the missile was conducted on 28 January 2013 from an under water launch platform off the coast of Visakhapatnam.

Development
Development of the K-15 missile started in the late 1990s with the goal of building a submarine-launched ballistic missile for use with the Indian Navy nuclear-powered Arihant-class submarines. It was developed at the Defence Research and Development Organisation’s (DRDO) missile complex in Hyderabad.

The development of the underwater missile launcher, known as Project 420, was completed in 2001 and handed over to the Indian Navy for trials. The missile launcher is developed at Hazira in Gujarat.The Sagarika missile began integration with India’s nuclear-powered Arihant class submarine that began harbor trials on 26 July 2009.

By 2008, the missile was successfully test fired seven times, and tested to its full range up to four times. The tests of 26 February 2008, were conducted from a submerged pontoon 50 metres (160 ft) beneath the surface off the coast of Visakhapatnam.A land-based version of the K-15 Sagarika was successfully test-fired on 12 November 2008.A full range test of the missile was done on 11 March 2012.

The twelfth and final development trial of the missiles was conducted on 27 January 2013. According to DRDO Director General V. K. Saraswat, the missile was again tested for its full range of 700 km and met all its objectives with a single digit impact-accuracy. The test will be followed by integration of the missile with INS Arihant. On 25 November 2015, a dummy or unarmed K-15 Sagarika missile was successfully test fired from INS Arihant. In December 2015, it was reported that the K-15 missile has entered production.
