9th Airborne Command and Control Squadron, Hickam AFB, Hawaii



Serial Number:



Developed from the Model 367-80 airliner prototype the KC-135 and 707 are two of Boeing's most famous products. The KC-135 was designed based on an Air Force requirement for a high speed jet tanker capable of refueling the then latest generation of jet fighters and bombers. The KC-97s then in use required the jets to fly at very low speeds while the tanker struggled to fly as fast as possible. The KC-135 allowed both the tanker and the receiver aircraft to fly comfortably in the middle of their flight envelopes rather than at the edges. The EC-135B version of the Stratotanker was designed from the beginning as an airborne command post. For nearly forty years one of these aircraft was airborne at all times to provide command and control of the United States' nuclear forces in the event of a surprise attack. The primary external differences between these aircraft and the standard tankers are the large number of communications antennae along the top of the fuselage and the addition of a refueling receptacle above the cockpit. In the mid-1960s this aircraft and two others were modified to EC-135J standards. Under the code name "Silver Dollar" they were assigned to Andrews AFB and were intended for use by the President as his airborne command post in the event of nuclear war.
