A plastic copy of the 30mm VOG-17 grenade currently seeing widespread use as an expedient drone delivered bomblet in Ukraine. The simple adaption involves the insertion of a printed bung into the fuze body through which a nail is inserted and held through friction. A safety tab is removed before use. On impact the nail is driven against a shotgun primer which initiates a plain detonator, setting off the main charge of PETN. The bomblet is especially lightweight and apart from rounding off the tip of the nail using a file, requires no tools to assemble.
Where high explosive is unavailable, dismantled shotgun cartridges provide a primer for the fuze, powder for the main charge and lead bird shot to fill the fragmentation sleeve, which in this configuration serves as a field expedient 'annoyance' device for keeping heads down.
Materials: Steel nail (30mm long, 2.5mm dia)
Main filling: 80g PETN
Fragmentation: 3mm dia, 74mm long steel round bar or 3" long nails with heads removed
Fuze operation: Nail + shotgun primer
