AFSOC fielded the U-28A fleet through the purchase of commercially available aircraft and subsequent military modification to include tactical communications capabilities, aircraft survivability equipment, electro-optical sensors, and advanced navigation systems. The advanced radio-communications suite is capable of establishing U.S. Department of Defense and NATO data-links, delivering full-motion video, and transmitting secure voice communications.
