The Akash (sky) is a mid-range surface-to-air missile (SAM) system built by India’s state-owned Defence Research and Development Organisation (DRDO).
The missile was developed under the integrated guided-missile development programme (IGMDP). The programme also involved the development of the Nag, Agni and Trishul missiles, as well as the Prithvi ballistic missile.
Akash missiles are designed to be launched from static or mobile platforms such as battle tanks and wheeled trucks, providing flexible deployment.
The integration of nuclear warhead allows the missile to destroy aircraft and warheads released from ballistic missiles. It can operate in all weather conditions.
