Various Indian missiles Prithvi It is India’s first indigenously built tactical “surface to surface” missile. It has a maximum range of 300 Km. It was first test fired in year 1988 from Sriharikota. It was induced into Indian Army in year 1994. Prithvi I is considered as India’s first indigenous ballistic missile. Naval variant of the Prithvi missiles are called Dhanush. The weight of Prithvi missile is about 4.5 to 5 Tons and it is designed to carry warhead of 0.5 Ton. All the variants of Prithvi can carry nuclear warheads. Prithvi I and Prithvi II are based on liquid fuels which increases set-up time before launching thus making these missiles redundant. Prithvi III uses solid fuel which is more reliable as it reduces operational set-up time. Prithvi III has range 350 Km plus which is considerably more than Agni I and Agni II. This is in service from year 2004.

Trishul It is a short range “surface to air” missile. It was designed for the primary function of defending naval ships against any missile attack, although it can be used to intercept low flying targets on land also. It has a range of 5 to 9 Km. The weight of the missile is 130 Kg and it can carry warhead up to 5 Kg. It was first successfully test launched in year 1988. This missile has been removed from service in year 2008.

It is a medium range multi target surface to air missile. It has capability of maximum range of 25 Km and altitude of 18 Km. Its primary use is to destroy flying targets in air like Fighter jets, and cruise missiles etc. It was successfully test launched in 1990. This missile was first designed by DRDO and it is being produced by Ordnance factories in collaboration with Bharat Dynamics and Bharat Electronics. Its designed weight is 720 Kg and it can carry war head of 60 Kg. It has inbuilt radar system which is used to intercept not only fighter jets but can also neutralise the cruise missiles. It has a speed range of Mach 3. It is fully mobile system and its launching platform is developed in such a way that it can be fitted both on a wheel and track type vehicle.

Brahmos It is named on Indian river Brahmaputra and Russian river Moskva. It earns the reputation of World’s fastest cruise missile. It was developed as a joint venture between DRDO and Russia. It has speed Range of 3 Mach and range of 300 to 500 Km. Its weight is 3 Tons and it can carry 200 KGs of conventional or nuclear warhead. It has three variants- i) land based, ii) Naval based, iii) Air and Submarine based. The land based and Naval based are already inducted in service while the Air and submarine based variants are still in development stage. The land based variant was first test fired in 2001 at Chandipur while the Naval based variant was test fired on 5 March 2008 from INS Rajput. Nirbhay It is India’s indigenously developed subsonic Cruise Missile. Its range is more than 1000 Km. this missile has the flexibility to be launched from land, air and naval base. The unique feature which distinguishes it from others is that it is completely stealth. The first launch of land based variant failed as it diverted from its trajectory. The second launch was successful on 17 Oct 2014.
