Project Indigo was started by India in 1962. An agreement was signed between India and Switzerland to develop an intermediate-range surface-to-air missile (SAM). Indigo was discontinued in later years without achieving full success. Project Indigo led to Project Devil, to develop short-range surface-to-air missile in the 1970s. Project Devil itself led to the later development of the Prithvi missile in the 1980s.
Background
