Agni-I is a short-range ballistic missile that was developed by DRDO of India in the Integrated Guided Missile Development Program. It is a single-stage missile that was developed after the Kargil War to fill the gap between the 250 km (160-mile) range of the Prithvi-II missile and the 2,500 km (1,600-mile) range of the Agni-II. It was first launched from a road mobile launcher at Integrated Test Range (ITR), Wheeler Island, on 25 January 2002. Less than 75 launchers are deployed.

A short-range ballistic missile (SRBM) is a ballistic missile with a range of about 1,000 km (620 mi) or less. In past and potential regional conflicts, these missiles have been and would be used because of the short distances between some countries and their relative low cost and ease of configuration. In modern terminology, SRBMs are part of the wider grouping of theatre ballistic missiles, which includes any ballistic missile with a range of less than 3,500 km.
