RC-135: A strange-looking bird
equipped for a secret mission

The hog-nosed RC-135 reconnaissance aircraft, Rivet Joint, bristles with an extensive antenna array and strange looking bulges on its fuselage.

It is a high-altitude version of the C-135, a militarized version of the veritable Boeing 707.

Rivet Joint aircraft are assigned to the 55th Wing, Offutt Air Force Base, Neb., and one is deployed to Kadena Air Base, Okinawa.

It provides direct, real-time reconnaissance information and electronic warfare support to theater commanders, mission planners and combat forces.

Information gathered by the RC-135 is made available to theater commanders, Department of Defense, and the National Command Authorities.

Data is processed, analyzed, and stored by Air Combat Command, Air Intelligence Agency, and National Security Agency specialists.

Internal reconnaissance equipment aboard the aircraft includes sensors, receiver systems, probe, blade, wire and dielectric panel antenna, and it is fitted with camera system windows.

The RC-135 also carries high, very high, and ultra-high frequency radios, conventional radar and doppler radar.

It also uplinks to DOD’s Global Positioning Satellite network, stellar and the INS navigation system.

The Rivet Joint works closely with the E-3A Airborne Warning and Control System (AWACS) during war or contingency situations.

However, there is no indication that reconnaissance flights which resumed Monday were done in concert with the AWACS.

Air Force officials earlier this year consolidated training for linguists assigned RC-135 Rivet Joint aircraft duties by moving initial aircraft qualification training to the 97th Intelligence Squadron at Offutt Air Force Base near Omaha, Nebr., headquarters of the U.S. Strategic Command, formerly the Strategic Air Command.

All Rivet Joint linguists receive qualification at the 97th IS before being assigned to one of the three RC-135 Rivet Joint locations at Kadena Air Base, Japan; Royal Air Force Base Mildenhall, United Kingdom, and Offutt Air Force Base, Nebr., officials said.

The other two variants of the RC-135 are the RC-135U Combat Sent, and the RC-135S Cobra Ball.

Their missions are more specialized than Rivet Joint, and the equipment carried aboard each version is unique to each model.

All RC-135s are equipped with an air refueling system, giving the aircraft unlimited range.

Operations supported by Rivet Joint over the past decade includes Urgent Fury, Eldorado Canyon, Just Cause, Desert Shield/Desert Storm, Proven Force, Provide Comfort, Southern Watch, Vigilant Warrior, Deny Flight, Provide Promise and Uphold Democracy.
