In an in-air demonstration in 2007, DARPA teamed up with NASA to show that high-performance aircraft can easily perform automated refueling from conventional tankers. The 2007 demonstration was not entirely automated, however: a pilot was on board to set conditions and monitor safety during autonomous refueling operations.
The DARPA Urban Challenge was held on November 3, 2007, at the former George AFB in Victorville, Calif. Building on the success of the 2004 and 2005 Grand Challenges, this event required teams to build an autonomous vehicle capable of driving in traffic, performing complex maneuvers such as merging, passing, parking, and negotiating intersections. As the day wore on, it became apparent to all that this race was going to have finishers. At 1:43 pm, “Boss”, the entry of the Carnegie Mellon Team, Tartan Racing, crossed the finish line first with a run time of just over four hours. Nineteen minutes later, Stanford University’s entry, “Junior,” crossed the finish line. It was a scene that would be repeated four more times as six robotic vehicles eventually crossed the finish line, an astounding feat for the teams and proving to the world that autonomous urban driving could become a reality. This event was groundbreaking as the first time autonomous vehicles have interacted with both manned and unmanned vehicle traffic in an urban environment.
In collaboration with the Department of Defense’s Joint Improvised Explosive Device Defeat Organization (JIEDDO), DARPA initiated the Vehicle and Dismount Exploitation Radar (VADER) program to design and deploy a radar system for unmanned aerial vehicles (UAVs) or small manned aircraft. Developed for DARPA by Northrop Grumman Electronic Systems, VADER provided synthetic aperture radar and ground moving-target indicator data to detect, localize, and track vehicles and dismounted troops.
Today, cost and complexity limit the Navy to fewer weapons systems and platforms, so resources are strained to operate over vast maritime areas. Unmanned systems and sensors are commonly envisioned to fill coverage gaps and deliver action at a distance. However, for all of the advances in sensing, autonomy, and unmanned platforms in recent years, the usefulness of such technology becomes academic when faced with the question, “How do you get the systems there?” DARPA’s Upward Falling Payloads program seeks to address that challenge.
Effective 21st-century warfare requires the ability to conduct airborne intelligence, surveillance and reconnaissance (ISR) and strike mobile targets anywhere, around the clock. Current technologies, however, have their limitations. Helicopters are relatively limited in their distance and flight time. Fixed-wing manned and unmanned aircraft can fly farther and longer but require either aircraft carriers or large, fixed land bases with runways often longer than a mile. Moreover, establishing these bases or deploying carriers requires substantial financial, diplomatic and security commitments that are incompatible with rapid response.
