INDIAN MISSILES

AGNI -I

Agni is an Intermediate Range Ballistic Missile. Agni-I used solid propulsion booster and a liquid propulsion upper stage, derived from Prithvi, essentially to prove the re-entry structure, control and guidance. The strap-down inertial navigation system adopts explicit guidance, which has attempted for the first time in the world. It uses all carbon composite structure for protecting payload during its re-entry phase. The first flight conducted in May 1989, established the re-entry technology and precise guidance to reach the specific target. Agni-I flight trials having proved the long-range technologies, an operational version of agni with solid-solid propulsion system was test fired in April 1999, which is Agni-II with mobile capability.

AGNI-II :

Agni-II Missile: The range for Agni-II is performance, repeated guidance more than 2000 km. The salient features of performance capability and salvo firing the test firings are mobile launch capability, capability. With the completion of above multi-staging, state-of-the-art control and flight trials, the design and development of guidance, re-entry technology and the Trishul Missile is complete. sophisticated on-board packages including (g) Nag Missile: Nag is a third generation anti-advanced communication. Agni�II has also tank missile with �top-attack� and �fire and been inducted into Services. forget� capability.

AKASH:

Akash System is a medium range Surface to Air Missile with multitarget engagement capability. It uses high-energy solid propellant for the booster and ram-rocket propulsion for the sustainer phase. The propulsion system provides higher level of energy with minimum mass, compared to conventional solid/liquid rocket motor, that has better performance with minimum weight of the missile. It has a dual mode guidance, initially on command mode from a phased array radar and later radar homing guidance with unique software developed for high accuracy. The phased array radar provides capability for multiple target tracking and simultaneous deployment of missiles to attack four targets at the same time, in each battery. Multiple batteries constitute a group centre. The system is highly mobile and has gone through a number of flight trials providing the command guidance.

BRAHMOS :

BRAHMOS is a supersonic cruise missile and can be used against ship and land targets. It has a range of upto 300 kms. The missile is uniquely configured for installing in ships, submarines & aircraft and on ground vehicles. It has been flight tested twice during June 2001 and April 2002 meeting all mission objectives.




PINAKA:

Multi-Barrel Rocket System PINAKA, an area weapon system to supplement the existing artillery gun at ranges beyond 30 kms, having quick reaction time and high rate of fire has been accepted by the user after extensive trials



PRUTHVI:

Prithvi is a Surface-to-Surface Battle field Missile. It uses a single state, twin-engine liquid propulsion system and strap-down inertial guidance with real-time software incorporated in the onboard computer to achieve the desired accuracy during impact. Prithvi has higher lethal effect compared to any equivalent class of missiles in the world. Prithvi is a unique missile today having manoeuverable trajectory and high level capability with field interchangeable warheads. Its accuracy has been demonstrated in the development flight trials. Flight trails for Air force has been completed. This system is now being configured for launching from ship, increasing its capability as a sea mobile system.

TRISHUL:

Trishul is a Quick Reaction Surface to Air Missile. It can also be used as an anti-sea skimmer from a ship against low flying attacking missiles. It employs dual thrust propulsion stage using high-energy solid propellant in a maraging steel flow chamber, and is operated on command guidance initially with ka-band gathering and then transferred to the tracking radar. It has necessary electronic counter-counter measures against all known aircraft jammers.

Trishul, with its quickest reaction time, high frequency operation, high manoeuverability, high lethal capability and multi-roles for three services, is state-of-the-art system providing considerable advantage to the Armed forces. This system has gone through development flight trials for army and sea skimmer trials for navy. The final evaluation is in progress before user trials.
