India has successfully test-fired a naval version of its Prithvi-III nuclear-capable missile, defence sources say.
The launch took place on Wednesday in the Bay of Bengal off Chandipur in the state of Orissa.
India’s nuclear rival, Pakistan, test-fired its own nuclear-capable missile on 12 October.
Both countries have continued test launches on a routine basis despite the recent peace process.
The latest launch comes two days after Pakistani President Pervez Musharraf suggested a new initiative to end the long-standing bilateral dispute over Kashmir.
The Prithvi has a range of up to 300km (180 miles), can carry a nuclear warhead and can be launched either from a ship or submarine.
The Press Trust of India said the latest launch was the first from an artificial underwater platform.
Pakistan has conducted four tests this year of its nuclear-capable Ghauri missile.
