Two solar missiles deployed by terrorists against security forces were seized by police in Kupwara district in June this year, Government said on Wednesday.
The solar-powered missiles are self-firing and self-charging missiles and need no human assistance for triggering.
"Two solar missiles were recovered by the police during search operations in Kupwara district on June 1 this year and measures have been taken by forces to avert hostile strikes," Defence Minister AK Antony said in reply to a question in the Rajya Sabha.
Answering another query on the Dhruv helicopter, the Minister said the service ceiling of the chopper has been laid down as 6000 meters which has been achieved by it.
The Comptroller and Auditor General (CAG) had said recently that the HAL-built indigenous chopper was not upto the mark and overweight for replacing the Cheetah/Chetak helicopter fleet of the armed forces.
In reply to another query, Antony said the DRDO was working on developing foliage penetration radar for all Unmanned Aerial Vehicles (UAV).
