The "UZ" fuze is a reaction-inertia fuze equipped with an electropyronic device for remote arming and self-destruction. It is typically used to equip the warhead of the OFZBCh-50 (Geran-2 UAV), but has also been observed in other UAVs, such as the “Lancet” and “Kub” (OFBCh-2.5), and of course, the V2U has now been added to this list. This type of fuze can be installed either as a nose fuze or a tail fuze.
