K4 - SLBM

The K-4 is a project of the Defence Research Development Organisation (DRDO) and it was kept secret for many years. The missile is approximately 12 metres (39 ft) long, has diameter of 1.3 metres (4 ft 3 in) and weighs 17 tonnes (19 tons). It can carry a warhead up to 2 tonnes (2.2 tons) and uses solid propellant. This missile could be best characterised as a hypersonic cruise missile as it remains within the earth’s atmosphere during its entire flight duration. To make it even more survivable, it follows a zig-zag path in three dimensions. Defence scientists involved in the missile's development stated that the aim of the missile was to achieve a high accuracy, with a close to zero Circular error probable (CEP)

Sagarika Missile

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.Sagarika has a length of 10 metres (33 ft), diameter of 0.74 metres (2 ft 5 in), weighs 17 tonnes and can carry a payload of up to 1,000 kilograms (2,205 lb) over 700 kilometres (435 mi). It was developed at the DRDO’s missile complex in Hyderabad
The missile was successfully test fired seven times, and tested to its full range up to four times. The tests of February 26, 2008 was conducted from a submerged pontoon 50 metres (160 ft) beneath the surface off the coast of Visakhapatnam.
