India is likely to testfire its indigenously developed new sub-sonic cruise missile Nirbhay next month, sources said Wednesday.

"The Defense Research and Development Organization has made the missile which can travel at a sub-sonic speed that is less than the speed of sound. It will be testfired in April," the sources said.

Nirbhay, India's equivalent of America's long-range Tomahawk, is a two-stage, surface-to-surface missile which can carry multiple payloads and engage several targets. It has a range of nearly 1,000 km.

Nirbhay will be a terrain hugging, stealthy missile capable of delivering 24 different types of warheads depending on mission requirements and will use an inertial navigation system for guidance.

"It will supplement Indo-Russian made BrahMos supersonic cruise missile in the sense that it would enable delivery of warheads farther than the 300 km range of BrahMos," the sources added.
