Armament All 60 to 81 mm mortars. Development By NFV to NATO requirements. Description This is an electronic proximity fuze with an optional, selectable, impact mode. Power for the proximity function is provided by a turbo-alternator driven by air as the fuze moves along the trajectory. The fuze is delivered set for proximity mode and is prepared by simply removing the plastic cap before loading. By turning the plastic cap to the `Impact' mark before loading, the proximity mode is inhibited and the fuze functions
on impact. Should the proximity circuit fail, then the impact mode will function when the bomb strikes the ground. The impact mode actually gives a slight delay, approximately 20 ms, for better effect against covered targets. The fuze is very well protected against ECM by an apex sensor, the antenna diagram, broadband frequency modulation, a spread in frequency and a blocking channel. Manufacturer Kongsberg Gruppen AS .
