As far as the ground realities of India's security environment are concerned, a factual analysis will be pertinent. The Prithvi has an estimated range of 250 km to 500 km, carrying a payload of 250 km to 500 km, carrying a payload of 250 kg; or a range of 150 km if it carries a heavier payload of 1,000 kg. In comparison, Pakistan has an arsenal of M-9 and M-11 ballistic missiles obtained from China; and has developed the indigenous HATF I, HATF II, HATF III missiles, based on Chinese technology. While HATF I missile has a 60 to 100 km range carrying payloads of 500 kg, HATF II and HATF III, the solid state propellant missiles, have a range of 300 to 600 km carrying payloads matching and, in excess of, Indian missiles. While India's missile programme is transparent and has received much hype, Pakistan has not been subjected to the same kind of scrutiny.
