40×51 mm MV (40 mm medium velocity)
The 40×51 mm MV cartridge was designed by Rheinmetall Denel Munitions for the US Special Operations Command (USSOCOM) after a 2008 requirement for enhanced range and lethality from hand-held 40 mm grenades. Rheinmetall answered by developing a new family of 40 mm grenades named 40 mm medium velocity and by 2019 the cartridge was undergoing NATO qualification.
