The official at the Defence Research and Development Organisation said today's test was the fourth for the Agni III missile.
The first attempt in 2006 failed, but last two tests were successful.
India's arsenal of missiles is mainly intended for confronting neighbour and archrival Pakistan. The long-range Agni III, by contrast, is designed to reach 1,900 miles -- putting China's major cities in range, as well as Middle Eastern targets.
