The FN P90 submachine gun (SMG) was developed in the late 1980s as a defensive weapon for the troops whose primary activities does not include small arms - vehicle and tank crew members, artillery crews etc. Standart pistols and SMGs chambered for pistol rounds were proved ineffective against enemy soldiers, wearing armour (bulletproof) vests, so FN Herstal developed a new round with enhanced penetration - the SS190. This round looks like scaled downt 5.56mm NATO round and forces the pointed, steel core bullet to the 600-700 meters per second at the muzzle, thus being capable to defeat standart CRISAT helmets and armour vests at reasonable distances (50-100 meters).

The P90 is a blowback operated, selective fire weapon. It is fed from 50-rounds box magazines, made from transluscent polymer. The magazine is being located above the barrel, with the cartridges being aligned at 90 degrees to the barrel axis. Each magazine has built-in ramp that rotates cartridge to align it with the barrel prior to chambering it.

The P90 controls are completely ambidextrous, with charging handles located at the both sides of the weapon, and the safety/fire mode selector is located below the trigger. The P90 also features downward ejection of the spent cases. P90 is built in bull-pup configuration, with polymer stock, and features built-in reflex collimator sight with 1X magnification and reticle automaticaly ajustable to the light level, as well as a set of the backup open sights. P90 may be equipped with special silencer, that should be used with special, sub-sonic variant of the 5.7x28mm cartridge.

P90 may be referred as a forerunner of the PDW (Personal Defence Weapon) concept, that arose in last 4 or 5 years.

P90 is used by Saudi Arabia, Peruan Special Forces and some special units of Thailand army, and offered for export by FN.
