Agni II is part of India's Agni series of ballistic missiles, developed by the Defence Research and Development Organisation (DRDO). It is an intermediate-range ballistic missile (IRBM) with an officially stated range of over 2000 km (often cited around 2000-3000 km). The term "ICBM" usually refers to missiles with ranges exceeding 5500 km, but "more than 2000 km" falls within the range capability of Agni II.
