The Prithvi missile is a family of tactical surface-to-surface short-range ballistic missiles (SRBM) and is India's first indigenously developed ballistic missile.
Development of the Prithvi began in 1983, and it was first test-fired on February 25, 1988 from Sriharikota, SHAR Centre, Pottisreeramulu Nellore district, Andhra Pradesh.
It has a range of up to 150 to 300 km. The land variant is called Prithvi while the naval operational variant of Prithvi I and Prithvi II class missiles are codenamed Dhanush (meaning Bow). Both variants are used for surface targets.
The initial project framework of the IGMDP envisioned the Prithvi missile as a short-range ballistic missile with variants for the Indian Army, Indian Air Force and the Indian Navy.
Over the years the Prithvi missile specifications have undergone a number of changes.
The Prithvi I class of missiles were inducted into the Indian Army in 1994, while Prithvi II with an extended range were being inducted in 2006.
Prithvi III class has a longer-range of 350 km, and was successfully test fired in 2004.
