The PBK-500U Drel (Russian: Дрель, lit. "drill") 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 being introduced to the Russian military in 2024.[1][2][3][4][5] Bazalt considers equipping Drel with a pulsejet engine to increase its range.
