Akash is a mobile area defense medium-range medium and high altitude surface-to-air missile with a range of 27 to 30 kilometers. Akash has a multi-target handling capability, and employs a command guidance system with provision for terminal guidance. Powered by a ram rocket propulsion and an air breathing engine, Akash can cut through electronic jamming with its electronic couter-counter measure equipment. It has a capacity to carry 50 kg payload. The missile has a height ceiling of 18,000 meters and is capable of detecting and destroying aircraft flying at tree top height. The missile systemís fire control radar is a multi-target and multi-function phased array radar called 'Rajendra' with a range of about 60-km, working in tandem. The radar and the missile can track 64 targets of which four can be engaged simultaneously. The BEL-developed "Rajendra" multi-functional radar system has been integrated with the system. The Akash self propelled launcher (ASPL) and Phased Array Radar have been been developed, though it has yet to enter the production/induction phase. For training the men and officers in handling Akash, scientists have developed simulator of the missile's seeker head in look down role and battery level radar under clutter and jamming environment. It is a part of the Integrated Guided Missile Development Program (IGMDP) undertaken by the Defence Rasearch Development Organisation (DRDO) in 1983. The system has undergone a few tests earlier to gauge proposition parameters and predicted values. By 1998 five flight trials had been conducted. India's IGMDP was launched in July 1983. Initially, it had a budget of around Rs 400 crore, but it has since been revised Rs 800 crore. The major programs under the IGMDP are the development of missiles including Agni, Prithvi, Akash, Trishul and the Nag. The Sagarika and the Surya have since been added to the IGMDP.
