Prithvi, India's most sophisticated medium-range missile, was successfully test-fired from the Integrated Test Range at Chandipur, 15 km from Balasore, Orissa, on Tuesday.

Defence Research and Development Organisation scientists, who conducted the test, described it as a user's trial.

The indigenously developed missile, with a range of 150 to 250 km, was fired at 11.27 IST, according to ITR sources.

The test was part of the efforts to further fine-tune the missile, which has already been inducted into the army, the sources said.

The 8.56 metre-high and one-metre thick missile, which took off perfectly, is part of India's Integrated Guided Missile Development Programme. It was developed for the army, air force and navy.
