YUMA PROVING GROUNDS, Ariz. — A 10,000-pound payload dropped from a C-130 at 25,000 feet over Yuma Proving Grounds, Arizona, is guided by the Joint Precision Airdrop System. JPADS provides safe/accurate high altitude delivery to ground troops, while also protecting the aircraft, aircrew and the supplies. JPADS has a steerable canopy, an electro-mechanical steering actuator with an airborne guidance unit. The mobility community is calling JPADS the JDAM (Joint Direct Attack Munition) for logistics, because both are GPS-guided systems. JPADS delivers supplies and JDAM delivers guided munitions attacks.
