Sharpening its missile prowess, India on Wednesday successfully test-fired its indigenously developed nuclear capable Agni-I ballistic missile with a strike range of 700 km from a test range off Odisha coast.

The surface-to-surface missile was test-fired from a mobile launcher at about 0830 hrs from launch pad-4 of the Integrated Test Range (ITR) at Wheeler Island, about 100 km from Balasore in Odisha, defence sources said.

Describing the test as successful, ITR Director MVKV Prasad said, "It was a practice trial conducted by the Strategic Force Command of the Indian Army."

Agni-I, a single-stage missile powered by solid propellants, has a specialised navigation system which ensures that it reaches the target with a high degree of accuracy and precision, a defence scientist said.
