Navies around the world need to perform a variety of missions from Maritime Security Operations in territorial waters to Power Projection including interventions on external theaters of operations, and from coastal environments to the deep sea.
Maritime Patrol Aircraft (MPA) have been used intensively since WW2 to detect and prosecute submarines. These platforms are extremely useful as they can very rapidly rally areas of operational interest and deploy their sonobuoys at sea. They operate covertly in passive mode or creating a surprise effect for a submarine. The latest technological advances have introduced spectacular breakthroughs in this field through the variety of buoys used and the performance of the processings developed.
