RD USA’s Blast Attenuation Device for 30mm cannons is the first suppressor I’m aware of in that caliber.
Promising attenuation of over 80% of the pressure of a 30mm cannon, the technology fits right in with the Department of Defense’s recent emphasis on lowering service member’s exposure to over pressure.
Developed by RD USA, the BAD-30 will be on display in their booth (#4125) as well as the Northrop Grumman booth (#1325) which coordinated on its development.
