The extended version of Prithvi, India's most sophisticated medium range surface-to-surface missile, was successfully test fired from the Integrated Test Range at Chandipur on Friday.

The extended version has been developed for Indian Air Force and has a range of about 150 to 200 kilometers, defence sources said. It was test fired from a mobile launcher at about 10.10am from the ITR, about 13km from Balasore, Orissa.

The 8.5metre high and one metre thick missile had a perfect lift-off. It has a launch weight of 4.6tonne, including a one-tonne payload.

This variant of the missile takes just 300 seconds to reach a target located at a distance of 150km.

Part of the country's Integrated Guided Missile Development Programme, the missile has the latest on-board computer and an advanced navigation system. It can use both solid and liquid propellant fuel.
