The RC-135V/W is tasked with real-time electronic and signals intelligence-gathering, analysis, and dissemination in support of theater and strategic-level commanders. The extensively modified C-135s detect, identify, and geolocate signals throughout the electromagnetic spectrum.
Rivet Joint is mostly used to exploit electronic battlefield intelligence and deliver near-real-time ISR information to tactical forces, combatant commanders, and National Command Authorities.
The British Royal Air Force also operates three RC-135W Airseeker aircraft, which are co-crewed by USAF/RAF personnel under an agreement through at least 2035. Onboard capabilities encompass rapid search, detection, measurement, identification, demodulation, geolocation, and fusion of data from potentially thousands of electronic emitters.
Continuous baseline upgrades keep the fleet viable through 2040 and drive standards for Combat Sent/Cobra Ball. Flexible funds permit rapid, variant-specific mods in response to emerging/evolving threats.
The current Baseline 11/12 modernized cockpit and operator interface, added new direction finding COMINT, precision ELINT/SIGINT, improved collection in dense-signal environments, enhanced near-real-time data dissemination, and integrated RC-135 with the Distributed Common Ground Station (DCGS).
USAF is currently upgrading the recently fielded Baseline 13 aircraft and beginning Baseline 14 integration. Baseline 13 included signal search and geolocation improvements, wideband signal recording, jam-resistant search, moving emitter target location and tracking, and wideband data link improvement. Baseline 14 will incorporate signal recording and spectral receiver enhancements, modernized navigation, surveillance, and air traffic management (CNS/ATM), advanced Mode 5 IFF, and upgraded autopilot. Development includes Baseline 15, automated search and detection, employment of artificial intelligence, and collaboration to speed collection, analysis, and distribution.
USAF recently tested an Electromagnetic Warfare Integrated Reprogramming (EWIR) concept to enable the RC-135 to quickly respond to evolving adversary tactics in a high-threat environment.
Rivet Joints notably supported border surveillance efforts along the U.S.-Mexico border in early 2025 operating in conjunction with a Navy P-8 Poseidon conducting maritime surveillance of the Gulf of Mexico.
