TheKGGB(Korean GPS-Guided Bomb) is anair-to-groundglide-guided weapon system, attached toMK-82conventionalgeneral-purpose bomb.^[2]The KGGB is capable of striking targets from long-distances and featuresfire-and-forgetcapability.^[3]It was developed by theAgency for Defense Development(ADD) andLIG Nex1.

Design

The KGGB is a medium-range air-to-ground guided weapon with improved accuracy and range attached withGPS-aidedINSguided kits in conventional general purpose bombs. Mission plan data established on the ground is stored in the Pilot Display Unit (PDU) controlling the KGGB, entered into the fighter-mounted KGGB, and after takeoff, if a bomb is dropped within 103 km of the mission area, the bomb will fly in the air and hit the target.^[2]

The KGGB kit is equipped with a special wing assembly calledFlaperonthat can control flight direction, flight altitude and flight speed in the air. This special wing assembly controls the flight direction by adjusting the lift force of the wing during flight, or acts as a flight altitude increase, deceleration or flight altitude decrease, acceleration of flight speed, and serves to fly further away and accurately hit the intended target.^[4]

The KGGB's built-in GPS and INS devices allow the bomb to attack targets precisely, and the fighter can safely return to the base immediately after the bomb is dropped, ensuring fighter and pilot viability. The KGGB is a standalone type guided weapon that can be mounted onF-4 Phantom,F-5 Tiger,F-15K Slam Eagle,F-16 Fighting Falcon,FA-50 Fighting EagleandKF-21 Boramaefighter jets and is remotely controlled by the PDU without the need for further modifications or systems to the aircraft.^[2]
