The official US Air Force name for the U-2 reconnaissance aircraft is Dragon Lady. This appellation can be traced to the Milton Caniff-drawn cartoon strip Terry and the Pirates that originated in the 1930s. The aircraft is often called Deuce and The Article by pilots. It has also been called Angel.

Beale AFB, California (1st Reconnaissance Squadron: pilot and maintenance training; 99th Reconnaissance Squadron); South Korea (5th Reconnaissance Squadron; Cyprus (eastern Mediterranean region); Southwest Asia (99th Expeditionary Reconnaissance Squadron); Palmdale, California (flight test, upgrades, and programmed depot maintenance).
Thirty-four, including five two-seat trainers and two ER-2s operated by NASA.
Most of the current fleet of U-2s was built in the late 1980s. The fleet has about eighty percent of its service life remaining.
The aircraft gathers imagery in a number of ways, including through digital imagery, radar imagery, and traditional wet-processed film. Similarly the U-2 collects signals intelligence in various frequency bands with a variety of sensors. Datalinks on the aircraft allow for immediate transmission of sensor data. The U-2 carries an electronic countermeasure system for self-defense.
The aircraft features an interchangeable nose and various bays in the fuselage for carrying sensors. The aircraft can also carry two large wing-mounted pods, called superpods, and an upper fuselage pod.

The exact maximum altitude of the U-2 remains somewhat sensitive, though the US Air Force advertises the maximum altitude as 70,000+ feet. The amount of time the U-2 requires to attain initial altitude is one of its most impressive characteristics. The aircraft can climb to its initial operating altitude of 60,000 feet in about one hour.
The full-pressure suit, called the S1034, acts as a back-up cockpit for the pilot. The suit protects pilots from decompression sickness while they are flying or if they must eject at high altitudes. The suit inflates automatically to three and a half pounds per square inch and supplies 100 percent oxygen to the pilot when it senses a loss of cabin pressure.
The aircraft has bicycle-style gear in the fuselage. Small wheels on a flexible shaft called pogos are attached on the wings for taxiing and takeoffs. The pogos fall off the aircraft just after the aircraft lifts off the ground. They are reattached to the wings by a ground crew after the aircraft lands. With its glider-like wing, the U-2 wants to fly. So landings are essentially controlled stalls. During landings, the aircraft is routinely chased on the runway by another U-2 pilot driving a high-performance vehicle, such as a Chevrolet Camaro. The U-2 pilot driving the chase car communicates the height above ground so the pilot in the U-2 knows when to set the aircraft down.
The U-2 provides peacetime reconnaissance in support of disaster relief from floods, earthquakes, and forest fires. It also supports search and rescue operations. The NASA ER-2 performs atmospheric studies.
