 Among those successes was Agni, India’s first intermediate-range ballistic missile, which incorporated aspects of the SLV-III and was launched in 1989.From 1992 to 1997 Kalam was scientific adviser to the defense minister, and he later served as principal scientific adviser (1999–2001) to the government with the rank of cabinet minister.His prominent role in the country’s 1998 nuclear weapons tests solidified India as a nuclear power and established Kalam as a national hero, although the tests caused great concern in the international community.In 1998 Kalam put forward a countrywide plan called Technology Vision 2020, which he described as a road map for transforming India from a less-developed to a developed society in 20 years.
