The PBK-500U Drel is an inertial and GLONASS-guided cluster glide bomb developed by the Russian Federation, designed to destroy enemy armored vehicles and buildings. Drel is equipped with friend or foe identification system and electronic countermeasures making it resistant to jamming and radar detection and is planned to be introduced to the Russian military in 2018.[1][2][3][4] Bazalt considers equipping Drel with a pulsejet engine to increase its range.
