"Some unique solutions in guidance and rocket propulsion systems and system engineering" could be given to friendly nations with government approval, Kalam said in an interview to Doordarshan.

With a range of 2,000 km, Agni-II, the Intermediate Range Ballistic Missile (IRBM) test fired on April 11, is "uniquely configured for special types of warheads", including nuclear ones, Kalam said.

But deployment of the Agni class of missiles is subject to "government decision depending on world condition and various situations", he said in the interview telecast tonight.

India, with its Integrated Guided Missile Programme (IGMP), is the only country in the world which can develop different types of missiles simultaneously, he said.

Asked whether Pakistan's competitive testing of missiles bothered India, Kalam said, "We can buildany type of missile depending on mission requirements." The missile system was designed and configured at a new missile test centre "somewhere in the east coast of Orissa in a beautiful island", he said.

India is not dependent on any country for any of the components, sub-systems or software used in Agni-II, Kalam said.

Describing Agni-II as "Agni plus", he said it was highly mobile and could be moved to any region on rail or road.

A computer on board the missile monitors all its components during flight and sends data on 600 parameters required for effective control of the missile, to the ground.

The "ruggedised" Agni-II can be launched within a few minutes with limited facilities and manpower, he said, adding the missile trajectory could be quickly shaped and the payload manoeuvred to reach the target.

"It has been operationalised irrespective of what payloads or warheads will be integrated with the system," he said.

Advanced instrumentation and computer simulation has helped reduce the numberof test flights of missiles from 30-40 in the 1960's to less than ten now. The number of flight parameters has also increased from 100 in the 1980's to 600-1,000 now, Kalam said.
