FILE PHOTO — The U-2 provides continuous day or night, high-altitude, all-weather, stand-off surveillance of an area in direct support of U.S. and allied ground and air forces. It provides critical intelligence to decision makers through all phases of conflict, including peacetime indications and warnings, crises, low-intensity conflict and large-scale hostilities.The U-2 is a single-seat, single-engine, high-altitude, reconnaissance aircraft. Long, wide, straight wings give the U-2 glider-like characteristics. It can carry a variety of sensors and cameras, is an extremely reliable reconnaissance aircraft, and enjoys a high mission completion rate. Because of its high altitude mission, the pilot must wear a full pressure suit. The U-2 is capable of collecting multi-sensor photo, electro-optic, infrared and radar imagery, as well as performing other types of reconnaissance functions. (Air Force photo)

A U-2 Dragon Lady flies over the airfield at Beale Air Force Base, California, April 12, 2018. The U-2 was making a pass over to indicate the flight path for a practice formation demonstration with two T-38 talonss for the Beale Air & Space Expo scheduled April 28.

Airmen provide intelligence, surveillance, reconnaissance Airmen quickly remove the final pins from a U-2 before a flight Oct. 4, 2009. The sortie was Capt. Peter J. Gryn’s first combat mission. The U-2 is the primary source of high-altitude intelligence, surveillance and reconnaissance. Captain Gryn is deployed from Beale Air Force Base, Calif. (U.S. Air Force photo/Staff Sgt. J.G.

Soaring to altitude during exercise Northern Edge A U-2 Dragon Lady from Beale Air Force Base, Calif., departs the runway at Joint Base Elmendorf-Richardson, Alaska, May 3, 2017 during Exercise Northern Edge. Northern Edge is Alaska’s largest and premier joint training exercise designed to practice operations, techniques and procedures as well as enhance interoperability among the services. Thousands of participants from all services, Airmen, Soldiers, Sailors, Marines and Coast Guard personnel from active duty, Reserve and National Guard units?are involved.

U-2 A U-2S from Beale Air Force Base, Calif., prepares to land at Royal Air Force Fairford, England, June 9, 2015. U-2S pilots have a small margin of space to effectively land the plane without causing damage to the aircraft. (U.S. Air Force photo/Staff Sgt. Jarad A. Denton)
AI Copilot: Air Force achieves first military flight with artificial intelligence A U-2 Dragon Lady assigned to the 9th Reconnaissance Wing prepares to land at Beale Air Force, Calif., Dec. 15, 2020. This flight marks a major leap forward for national defense as artificial intelligence took flight aboard a military aircraft for the first time in the history of the Department of Defense. The AI algorithm, developed by Air Combat Command’s U-2 Federal Laboratory, trained the AI to execute specific in-flight tasks that would otherwise be done by the pilot. The flight was part of a specifically constructed scenario pitting the AI against another dynamic computer algorithm in order to prove both the new technology capability, and its ability to work in coordination with a human.
