FN Herstal started the design of the 5.7x28mm cartridge in the late 1980s when body armour was becoming standard combat equipment and the modern-day missions required a more appropriate and more effective cartridge.
Simultaneously, the Company designed the FN P90® Personal Defence Weapon (PDW), then later the FN Five-seveN® pistol, two weapons firing 5.7x28mm ammunition that are currently in service with a large number of police and security forces across the globe.
The 5.7x28mm calibre is now a NATO standard (STANAG 4509).
