Sonar systems

Ultra's Sonar Systems business is supplying the integrated sonar suite consisting of hull mounted and variable depth sonars to Australia's Air Warfare Destroyer programme, as well as the medium frequency sonar to the Royal Navy's new Type 45 destroyer. These systems represent a modular, integrated suite of sonars for advanced anti-submarine warfare and will detect a range of threats including submarines, torpedoes and mines. The system is also capable of providing bi-static and multi-static capability integrating all ASW assets in the force. Ocean Systems developed and supplies the MK54 torpedo array nose assembly and the TR-317 spherical array transducers, the chin array, the low cost conformal array, and the high frequency sonar sail array for the US submarine fleet. A derivative sonar system is protecting the underwater intakes of hydro-electric plant from the ingestion of migrating fish. Maritime Systems supplies advanced towed array sensors for the Canadian DND, the Netherlands and for the UK, and a variety of surface ship towed and deployable high power acoustic projectors and receiver systems. Sonar Systems also supplies a range of sea-bed imaging sonars for military and civil applications including hydrographic survey and mine countermeasures. These sonars operate in sidescan, bathymetric and synthetic aperture modes, the latter mode providing greatly enhanced image resolution over conventional sonars of comparable size. Maritime Systems provides consultancy, training, support and calibration services in the areas of sonar and hydro-acoustics.
