AF71 (FTM 1) is a point-detonating fuze with super quick and graze (anti-ricochet) function, independent of impact angle, and is intended to be used with fragmentation and high-explosive fragmentation Rounds for: ATGL-L family, Russian RPG-7V, ATGL-H family, Russian SPG-9 and 2A28 Gun.
AF71 (FTM 1) gets armed upon axial overload of at least 1000 g (acceleration of gravity).
The Fuze is safe upon handling, operation and transportation with any kind of transport means, upon firing, as well as at the time of flight, and upon dropping from 3 m height on any kind of ground and in any position of falling.
When assembled in the Grenade, upon falling from 1.5 m height, the Fuze keeps its operational characteristics.
The Fuze reliably actuates upon firing at any aiming distance on swampy ground, ground with middle hardness, stony ground, as well as on ground covered with snow and ice.
A mechanism that provides the reliable functioning upon ricochet distances is included in the Fuze construction.
