Agni-III is a nuclear-capable missile developed by India which can hit strategic targets deep inside China with a strike range of 3,500-4,000 km. It is expected to be test-fired sometime between April and May 2004. It falls short of the range of ICBMs (intercontinental ballistic missiles) which have ranges over 5,000 kilometres.

This is the third in the Agni series of missiles. The Agni-I has a range of 700-800 km while the Agni-II has a range of about 2,000 kilometres. They are claimed to be a part of the "credible deterrence" against Pakistan. The Agni-II can only reach some parts of western China.
