Summary edit

Description

(South Dakota Air and Space Museum collection, Ellsworth Air Force Base, Rapid City, South Dakota, USA)


From exhibit signage:

EC-135A Airborne Launch Control System (ALCS)

Top Speed - 610 miles per hour Crew - 15+ Range - Intercontinental Payload - No weaponry; 31,000 gallons of fuel

An Airborne "Finger on the Button"

Crammed with electronics, one of three ALCSs from Ellsworth Air Force Base sat ready for takeoff at all times between 1970 and 1991. If an attack on the United States disrupted ground-based launch control sites, this plane's crew - from 30,000 feet in the air - could send nuclear missiles rocketing around the globe. But it was never really a button; crews turned keys to launch the missiles.

Specialists on board could communicate up and down the chain of command, from the President to individual combat crews.

Pumping Fuel at 300 miles per hour

Before it was converted for missile launch, this plane served Ellsworth Air Force Base's B-52 bombers as a flying gas station. Tankers from the 28th Air Refueling Squadron met bombers in midair, connected through the tail boom, and filled the bomber's tanks.
