Bell has explored high-speed vertical lift aircraft technology for more than 85 years, pioneering innovative VTOL configurations like the X-14, X-22, XV-3 and XV-15 for NASA, the U.S Army and U.S. Air Force. The lessons learned from the XV-3 and XV-15 supported the development of the Bell-Boeing V-22 Osprey tiltrotor, an invaluable platform that changed the way the U.S. military conducts amphibious assault, long range infiltration and exfiltration and resupply with a cruise speed and range twice that of helicopters it replaced.
