ABSTRACT:
An autonomous underwater acoustic charge deployment buoy that can deploy ustic charges at preselected time periods. The device can operate away from any control vessels or structures. The device comprises a plurality of launch tubes disposed within a frame supported by an elastomeric floatation collar. An electrical control circuit is fastened to the upper surface of the frame to control acoustic charge release times. A hinged door that is held closed by a burn wire is disposed on lower end of each launch tube. Activation of the control circuit causes the burn wire to part, releasing the hinged door. When the hinged door opens, gravity causes the acoustic charge to drop from the launch tube. The device can deploy a plurality of acoustic charges at preselected times remote from control vessels or structures.
