India has successfully tested Agni III missiles range upto 3000 kms capable of carrying Nuclear bombs. It is 16 meter long missiles and has payload capacity upto 1.5 tonnes. Now India can reach remote location of China and hit them in case of war. This is one step further for Indian defence to becoming self dependent and will not have to rely on other nation.
It is necessary for India to increase its defence capability because day by day China and Pakistan becoming threat for India. Pakistan has increased there defence capability by the help of US and China and on the other hand China is already capable of all this thing. As also China has built underground submarine base near Sanya base. This is now under reach of India by the help of Agni III missiles. Agni III will also increase power in Indian Sub-Continent.
The final step for Indian defence would be Agni IV Intercontinental ballistic missile which has range up to 6000 km, it is still under development.
