The cruise missile Hatf VII Babur that Pakistan test-fired Aug 11 was subsonic and not a supersonic missile, a defence official said here on Sunday.
"What our neighbouring country has built is a subsonic and not a supersonic missile. As per my knowledge, the cruise missile tested by Pakistan recently is a subsonic one unlike our Brahmos supersonic cruise missile," scientific advisor to Defence Minister M. Natarajan said while delivering the 21st Brahm Prakash Memorial Lecture.
The ground-launched cruise missile Hatf VII can carry nuclear and conventional warheads with a range of 500 km.
Pakistan claimed it had joined a select group of countries that have the capability to design and develop cruise missiles.
"As I understand, the Pakistani missile was tested with the help of another country," Natarajan said in an oblique reference to China at the Indian Institute of Science (IISc) here.
India successfully test-fired Brahmos in 2003 at a speed of 2.8 mach and a range of 290 km. The supersonic cruise missile was developed as an India-Russia 50:50 joint venture and named after the Bramhmaputra and Moscow rivers.
"Brahmos is already in the production phase. The Indian Navy has placed an order for 18 cruise missiles. We are in the process of selling its concept to the army, as it can also be launched from land.
"At the design level, we are looking at the possibility of using it for the air force too," Natarajan told reporters later on the sidelines of the function.
