India to equip vessels with screaming cannon
Thursday, 29 September 2011 21:51

India’s naval forces, which are participating in combating piracy in the Gulf of Aden and the Arabian Sea, will equip their ships with special "screaming cannon."

The long-range acoustic devices are capable of delivering powerful sonic booms, as well as shouting threats and warnings in several languages​​. This "non-lethal weapon" is capable of crushing the adversary’s will to resist, by directing at it a sound "ray" of 150 decibels.
