that provides more sensors in the vicinity of ocean shield without having a ship there to pro-reduce the background noise. some very good work that was only started after the mh-370 aircraft was lost, very good work by the australian defense work, in particular the air force have modified the acoustic processor to pick up the 37.5 kilohertz frequency. we expect anytime now the aircraft, the first aircraft, the ocean shield will coordinate to lay a sonar buoy. it is a package parachuted out of the aircraft, floats on the surface of the ocean and will deploy a hydrophone, 1,000 feet below the surface of the ocean and it has a radio that transmits the data back to the aircraft. hp-3 is capable of carrying 30 on each mission and that will provide a range of sensors, a number of sensors, 1,000 feet
