Designed for a variety of missions, the SwordFishTM sonar is suitable for use on vessels of various sizes, including frigates, corvettes, offshore patrol vessels (OPV) and other small vessels. It complements DSIT’s BlackFish hull-mounted sonar (HMS) system and DSIT’s SeaShieldTM static active submarine detection sonar. when used for littoral defence, all DSIT’s sonar systems can now be operated via one onshore control station. This unique solution considerably reduces the number of sonar operators needed for coastal ASW operations. It also allows the re-allocation of precious ASW capable platforms for other important missions away from the littorals. This defence concept creates a unique solution for the defence of the littorals from submarines and smaller underwater threats.
