vAF-M17 / vFI-M17
vAF-M17 aerial bomb fuze with vFI-M17 initiator
An inertial electro-mechanical aerial bomb fuze with a microcontroller and an interrupted explosive chain that keeps the detonator physically isolated until arming, paired with a top-mounted initiator, offering arming delays from 2 to 25 seconds and detonation delays from instantaneous to 1000 seconds.
