ABSTRACT:
An anchoring device suitable for restraining line arrays comprises a cylir having a plurality of spring loaded flukes spaced both axially and radially from each other. The flukes retract flush into slots in the cylinder so that the anchoring device may be ejected from a submarine through a stuffing tube gland. The flukes until ejected are held in the retracted position by means of a caked water soluble material. A plurality of anchors may be ganged together by means of a coupling assembly. The same coupling assembly is suitable for connecting the anchoring device to the line arrays.
