Long Range Glide Bomb (LRGB)

Long Range Glide Bomb (LRGB)

The Long Range Glide Bomb (LRGB) is designed to extend the range of the Mk 80 series warheads, offering enhanced operational flexibility. It is an All-Up Round (AUR) capable of accommodating warheads ranging from Mk 81 to Mk 84. When released from an altitude of 12 km at 0.85 Mach, the estimated range as per post-flight analysis is 190+ km. The system can be integrated with terminal seekers such as Electro-Optical/Infrared (EO/IR) or a Passive Homing Head (PHH) to enhance accuracy. Furthermore, it is equipped with a jamming-resistant GPS, ensuring effective operation in the presence of GPS jamming.
