Glass cockpit

This is the "glass cockpit" of today's updated U-2S aircraft--the controls are now largely digital and electronic, where they used to be mechanical. The S designation came about in the mid-1990s when the Dragon Lady fleet began receiving airframe, sensor, and engine upgrades. The last delivery of U-2 aircraft to the Air Force from Lockheed Martin was in 1989. Today, just over 30 are in service (including some two-seat trainers), out of a total of 104 built over the course of about 35 years.
