The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs into all-weather precision-guided munitions. The JDAM kit includes a tail section that contains an inertial navigational system and a global positioning system guidance control unit, which improves the accuracy of unguided, general-purpose bombs in any weather condition. JDAM is a joint U.S. Air Force and Department of Navy program. JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a GPS receiver, giving them a published range of up to 15 nautical miles (28 km). JDAM-equipped bombs range from 500 to 2,000 pounds (230 to 910 kg). JDAM can be launched from very low to very high altitudes in a dive, toss, or loft and in straight and level flight with an on-axis or off-axis delivery. JDAM enables multiple weapons to be directed against single or multiple targets on a single pass. JDAM is currently compatible with B-1B, B-2A, B-52H, AV-8B, F-15E, F/A-18C/D/E/F, F-16C/D, and F-22 aircraft. Follow-on integration efforts are currently underway or planned to evaluate compatibility with the A-10, F-35 Joint Strike Fighter, and MQ-9 Reaper unmanned aerial vehicle.

JDAM can be launched in dive, toss, loft, and straight-and-level flight modes, and delivered either on-axis or off-axis from very low to very high altitudes. This allows for the delivery of diverse weapons directed against single or multiple targets on a single pass. JDAM can be configured with a variety of fuzing systems or proximity sensors. JDAM enables aircraft to employ weapons accurately against stationary ground targets, while Laser JDAM (LJDAM) enables prosecution of moving and maneuvering ground targets. Once released from the aircraft, the JDAM autonomously navigates to the designated target coordinates[[5]](http...
