Dhanush was test fired hours after armed forces successfully test-fired the nuclear-capable surface-to-surface Prithvi-II missile from the Integrated Test Range as a part of routine training exercise.
"It was a text book launch," Prasad said.
The indigenously-developed Prithvi-II ballistic missile has the capability to hit a target 350 km away.
Developed and built exclusively for the Indian Navy, Dhanush has a 250 to 250 km striking range and can carry a single warhead of up to 750 kg. The missile, which is a part of India's Integrated Guided Missile Development Programme, is about 8.53 metres long and 0.9 metre wide and has a launch weight of about 4.4 tonnes. It uses liquid propellant.
President Pranab Mukherjee and Prime Minister Narendra Modi Friday congratulated Indian scientists on the successful test firing of Prithvi-II missile. "I extend my heartiest congratulations to all those associated with the successful test-firing of India's indigenously developed Prithvi-II surface-to-surface missile," the president said in a message to Avinash Chander, Scientific Advisor to the Defence Minister and Secretary, Department of Defence Research and Development.
This significant scientific breakthrough has given a commendable boost to our efforts to step up indigenisation and improve self-reliance in our defence capabilities, he said. Modi said in his message: "I congratulate the hard work of our scientists that has been instrumental in the successful test fire of Prithvi-II missile".
