Abstract
It is recognized today that the best way to improve the detection capability of minehunters is linked to the operational concept of minehunting sonars rather than the performance increase of sonar transducers. The Variable Depth Sonar was a first step in this direction, permitting search and detection at greater depths. But this solution does not improve the ship survivability and generates complicated handling operations due to the static attitude of the towed body. The only way to have substantial improvements while increasing ship safety is to operate a Forward-Deployed Sonar (FDS), that will operate at greater depths and ranges than current VDS with fewer disadvantages. Feasibility studies have been conducted in order to define an FDS prototype and the associated operational concept. These studies concerned the vehicle (equipment, hydrodynamic, command and control, power generation, cable), the associated platform and the associated mine warfare concept. We concluded that such a sonar subsystem could change today's concept of minehunting and will probably lead to new standards of definition for minehunters.
