9LV is a Naval Combat Management System (CMS) from the Swedish company Saab. The 9LV was established when Philips Teleindustri AB (1975 renamed Philips Elektronikindustrier AB), a subsidiary of Philips of the Netherlands, was selected as the supplier of the torpedo and dual-purpose gun fire control system including a radar fire control director for the Royal Swedish Navy Norrköping-class torpedo boats.[1]
Prior to the Norrköping class, Philips provided torpedo fire control to Spica-class and Plejad-class torpedo boats, as well as to Sjöormen-class and Draken-class submarines, and also anti-submarine fire control for the Halland-class destroyers and Visby-class frigate. However, not until the air defence fire control and radar fire control director was introduced, the name 9LV was established; LV is the Swedish abbreviation for "luftvärn", i.e. air defence. [citation needed]
9LV is currently used on several classes of naval combatants, including the Australian Anzac-class frigates, the Swedish Visby-class corvettes, the Canadian Halifax-class frigates[2] and the Australian Canberra-class landing helicopter dock ships. It will be used on the Norwegian Coast Guard’s new Jan Mayen-class vessels.[3]
