India has developed a submarine-launched supersonic missile, a capability hitherto the monopoly of advanced nations like the US, France [Images], Russia [Images] and some others.

The submarine-launched version of Brahmos supersonic cruise missile is ready, Defence Minister A K Antony informed Lok Sabha on Wednesday.

He, however, said trials of the missile were awaiting the necessary platform, which will be identified by the Navy soon.

According to experts, the submarines in the armoury of the Navy namely the German HDW series and the Russian Kilo class do not have the capability to launch such missiles.

India has requested Russia for loan of submarines to carry out test trials of the underwater launched version of the Brahmos.

Alternatively, the trials could be carried out in Russian waters, naval sources said.

On the air launched version of the Brahmos, the minister said this was currently in progress and attempts were being made to integrate the missile to be launched from both Air Force's SU-30 MKI fighters and Navy's IL-38 maritime reconnaissance planes.
