ABSTRACT:
The aft drogue module (18) of the towed sonar array has a body (20) as its main length. The body (20) contains strength member (26) which is covered by an extruded tube (28) of rubberlike material which is covered by braid (30) and which, in turn, is covered by extruded abrasion-resistant cover sleeve (32). At its forward end, the strength member is expanded into the conical interior of coupling (22). The tail (56) is attached to the body and contains fill material (60) which damps and is sufficiently stiff to inhibit whipping during towing.
