Expendable Countermeasures

The Expendable Acoustic Device (EAD) is a programmable countermeasure utilising technology developed under previous Ultra countermeasure programmes. It incorporates low-cost features developed by Ultra under its sonobuoy programme, supporting a very low cost system ownership. The EAD is reprogrammable at dockside, prior to loading into the launcher or in-situ prior to entering a threat arena with an optional programmer. EAD launch may be initiated via the local control unit on each launcher or via a remote Launcher Control Unit (LCU(R)) sited in the Operations Room or the Bridge.
