It would appear that Agni-II has a theoretical ability to hit a target 3,000 km away with a 1,000 kg overall payload, a 250 kg RV with a 750 kg warhead. It is suggested that a 200 kiloton boosted fission warhead was earlier developed for the Agni system when it was on the drawing board in the late 80s, however after the Pokhran-II series of nuclear test in May 1998, the 200 kt boosted fission design has clearly given way to a 200 – 300 kt two stage thermonuclear design that is expected to be much lighter. Range changes can be made by either varying the payload or by altering the engine configuration.
