Abstract : An underwater vehicle sonar system has sonar sensors provided in arms to supplement a nose mounted array. The arms are capable of use in an extended position to provide a large diameter sonar array offering improved image resolution in the forward direction. In the extended position the arms also are capable of acting as active hydrodynamic control surfaces. Additionally the arms can he used in a stowed position to provide a linear array for side viewing.
