In-bore Fragmentation Lethality Assessment

Go4 Mine/IED Lifting & Exposure System

An inert IED has been buried in a surrogate test target.  The Go4 system consists of a primary hole-boring charge and a secondary soft lifting charge.  When the primary charge is fired, it bores an access hole under the IED, triggers a 3 second delay fuse in the secondary charge and drives it into the borehole under the IED.    In the video, after the 3 second delay, you will see the secondary charge fire (white puff of smoke) and eject the IED; that lands just behind the target bay.
