India, along with Russia, is developing a BrahMos supersonic cruise missile with a strike range of 800 km, China's Xinhua news agency quoted defence sources as saying on Saturday.
"The missile range was increased from 290 km to 450 km last year and now it is being raised to 800 km. The test firing of the missile is likely to take place by this yearend only," sources said.
The land and sea variants of BrahMos missile are already operational with the Indian Army and the Indian Navy. In November last year, India successfully test-fired the air version.
India on Thursday test-fired nuclear-capable, surface-to-surface Agni V ballistic missile.
Agni V is the most advanced missile in Agni series with a strike range of over 5,000 km.
