The December 1984 test flight of the X-29—the most aerodynamically unstable aircraft ever built—demonstrated forward-swept wing technology for supersonic fighter aircraft for the first time. Technology breakthroughs, among them a digital fly-by-wire flight-control system and carbon-fiber wing technology, made possible a lightweight design far more maneuverable than conventional aircraft. DARPA, NASA, and the U.S. Air Force jointly developed two X-29 technology demonstration aircraft, which the Air Force acquired in March 1985 and used for 279 test flights by April 1990.

Although Air Force fighter designs ultimately embraced DARPA’s stealth revolution rather than the high maneuverability promised by forward-swept wings, other X-29 technologies found their way into future aircraft. Advanced composite materials are now used extensively in military and commercial aircraft. Aeroelastic tailoring to resist twisting under flight loads is now a standard tool for advanced designs with relevant outcomes including the long, thin wings of the Global Hawk, an unmanned surveillance aircraft.

One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft's lift to power in hover or its efficiency during long-range flight.

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.

DARPA’s Tactical Technology Office (TTO) creates advanced platforms, weapons and space systems to help preserve U.S. military superiority through overwhelming technological advantage. However, constantly evolving technologies, shifting warfighter mission requirements and limited budgets mean TTO must always seek new ways to leverage innovation while fulfilling its duties.

Air-ground fire coordination—also known as Close Air Support or CAS—is a dangerous and difficult business. Pilots and dismounted ground agents must ensure they hit only the intended target using just voice directions and, if they’re lucky, a common paper map. It can often take up to an hour to confer, get in position and strike—time in which targets can attack first or move out of reach. To help address these challenges, DARPA recently awarded a contract for Phase II of its Persistent Close Air Support (PCAS) program to the Raytheon Company of Waltham, Mass.
