Abstract
A sonobuoy comprises a sonar array mounted on arms 2 that are pivotally connected to a central support 3 and housed by an outer housing 1. Upon entry of the sonobuoy into water a float 8 is deployed which since it is connected to the central support 3 by a line arrests the downward motion of the central support 3. The outer housing 1, by virtue of its inertia, travels on uncovering the arms 2 and positively locating the arms 2 by pulling on lines 17 connected to the arms 2. The use of the motion of the housing 1 to deploy the arms 2 eliminates the requirement for spring powered motors reducing the cost of the sonobuoy.
