<P> Design of the missile is similar to that of the SA - 6, with four long tube ramjet inlet ducts mounted mid-body between wings . For pitch / yaw control four clipped triangular moving wings are mounted on mid-body . For roll control four inline clipped delta fins with ailerons are mounted before the tail . However, internal schema shows a completely modernised layout, including an onboard computer with special optimised trajectories, and an all - digital proximity fuse . </P> <P> The Akash system meant for the Army uses the T - 72 tank chassis for its launcher and radar vehicles . The Rajendra derivative for the Army is called the Battery Level Radar - III . The Air Force version uses an Ashok Leyland truck platform to tow the missile launcher, while the Radar is on a BMP - 2 chassis and is called the Battery Level Radar - II . In either case, the launchers carry three ready - to - fire Akash missiles each . The launchers are automated, autonomous and networked to a command post and the guidance radar . They are slewable in azimuth and elevation . The Akash system can be deployed by rail, road or air . </P> <P> The first test flight of Akash missile was conducted in 1990, with development flights up to March 1997 . </P> <P> The IAF has initiated the process to induct the Akash surface - to - air missiles developed as a part of the Integrated Guided Missile Development Programme . The Multiple target handling capability of Akash weapon system was demonstrated by live firing in a C4I environment during the trials . Two Akash missiles intercepted two fast moving targets in simultaneous engagement mode in 2005 itself . The Akash System's 3 - D central acquisition radar (3 - D car) group mode performance was then fully established . </P>
