Nirbhay (Sanskrit: निर्भय, Nirbhay "Dauntless/Fearless") is a long range, subsonic cruise missile being developed in India by the Defence Research and Development Organisation
Nirbhay will be a all-weather low-cost medium-range cruise missile with stealth and high accuracy. The missile will have a range of 750km, which will be increased later. It will weigh about one tonne and will have a lenght of 6 metres. It will carry a ring laser gyroscope for high-accuracy navigation and a radio altimeter for the height determination. It will be capable of being launched from multiple platforms on land, sea and air and shall be inducted into Indian Navy, Army, and Air Force. In particular, Nirbhay will be adapted for the Indo/Russian Su-30MKI
the two-stage missile Nirbhay will be able to pick out a target and attack it among multiple targets. The missile will also have a loitering capability i.e it can go round a target and perform several manoeuvres and then re-engage it. With two side wings, the missile will be capable of flying at different altitudes ranging from 500 m to 4 km above the ground and can also fly at low altitudes to avoid detection by enemy radar. It would be capable of delivering 24 different types of warheads depending on mission requirements and will use an inertial navigation system for guidance. The missile will supplement Brahmos by delivering warheads farther than the 290 km range of Brahmos.
