The KGS-21 Heavy Submachine Gun is a submachine gun in service with the Armies of the Five Deserts and the Sultan's Navy since 2017, using the new 5.45x40mm Intermediate Cartridge, which was introduced at the same time. The KGS-21 is intended as a weapon for the crews of armoured and flying vehicles for self-defense and is, for now, not intended to replace the KGS-20 Submachine-Gun.

Despite being larger, heavier and using the same action system as well as ammunition as the KGS-26 Carbine, KGS and the Kyrenaian Armed Forces insist, that the KGS-21 is a Heavy Submachine Gun, not a carbine or an assault rifle.
