Open in interactive gallery →See aircraft like this on the live radar →

The Boeing RC-135 Rivet Joint (designated RC-135V + RC-135W) is the current principal variant of the RC-135 SIGINT family — Boeing's most-numerous USAF electronic-intelligence aircraft + the principal NATO airborne electronic-collection platform. Boeing built the original Rivet Joint conversions in 1973-1974 from existing C-135B airframes; the current Big Safari programme has progressively upgraded the fleet through 2026. About 17 Rivet Joint aircraft serve USAF 55th Wing at Offutt Air Force Base + 3 RC-135W Airseekers serve RAF 51 Squadron at RAF Waddington. The aircraft is the most-deployed NATO signals platform worldwide.

The RC-135V/W uses 4 × CFM International CFM56-2B-1 turbofans. Maximum speed 933 km/h, range 6,500 km, service ceiling 12,300 m, MTOW 132,000 kg. The aircraft is distinguished from other RC-135 variants by its distinctive 'cheek' antenna fairings on both fuselage sides — these contain SIGINT antennas for VHF / UHF / SHF radio + radar collection. Crew: 2 pilots + 3 navigators + 21-27 collection operators. Mission profile: typically 10-12 hour orbit at high altitude near (but outside) the airspace of intelligence-targeted countries — orbits over the Baltic Sea, Black Sea, eastern Mediterranean, South China Sea, + Korean Strait have been continuous for decades.

Rivet Joint service spans 1973-present. Recent operations: 2022-present Ukraine war Russian-territory monitoring (RC-135Ws have flown daily missions from RAF Waddington + USAF bases monitoring Russian military communications + radar emissions over Ukraine), 2024 + 2025 South China Sea monitoring (covering Chinese PLA Navy + PLAAF activities). The 29 September 2022 RAF RC-135W + Russian Su-27 incident over the Black Sea was a major escalation — a Russian Su-27 launched an R-77 missile at the unarmed RC-135W (the missile failed to track + dropped harmlessly into the sea). The UK + US responded by adding fighter escorts to subsequent Rivet Joint missions. The 17 Rivet Joints + 3 RAF Airseekers will continue in service through ~2050; replacement programmes (Compass Call + future Big Safari aircraft) will augment but not fully replace the RC-135V/W.

For Kids — a shorter, friendlier version

The Boeing RC-135 Rivet Joint is a special spy plane used by the American and British air forces. It listens to radio signals and radar from far away. This helps pilots and commanders learn what is happening in an area without flying into danger.

The plane has four powerful jet engines and can fly very far. Its range is about 6,500 kilometers, which is longer than a cross-country road trip across several countries. It can fly as high as 12,300 meters — well above most clouds.

You can spot a Rivet Joint by the big bumps on the sides of its nose. These bumps hold special antennas that pick up radio and radar signals. A large crew of up to 29 people flies on each mission, including pilots, navigators, and signal experts.

A typical mission lasts 10 to 12 hours. The plane flies in big circles high in the sky near — but outside — another country's airspace. It collects information the whole time it is up there.

About 17 of these planes serve with the American Air Force, and three serve with the British Royal Air Force. Together they are the most-used signal-gathering planes in NATO.

Fun Facts

  • The RC-135 Rivet Joint can stay in the air for 10 to 12 hours on a single mission!
  • It is heavier than 20 large elephants, with a top weight of 132,000 kilograms.
  • The plane has bumpy cheek fairings on both sides of its nose — those bumps hold secret listening antennas.
  • Up to 29 crew members can fly together, making it a very busy flying office!
  • The British Royal Air Force calls their version the RC-135W Airseeker.
  • It is the most-used signal-gathering plane in all of NATO.
  • The first Rivet Joint planes were built back in 1973 and 1974 from older cargo planes.
  • Four CFM56 turbofan engines power the plane to a top speed of 933 kilometers per hour.

Kids’ Questions

What does the Rivet Joint actually do up in the sky?

It listens. The plane flies high and collects radio and radar signals from far below. Special operators on board study those signals. This helps the air force understand what is going on in an area without going into dangerous airspace.

Why does the plane have those strange bumps on its nose?

Those bumps are called cheek fairings. They hold antennas inside them. The antennas pick up many kinds of radio and radar signals. Without them, the plane could not do its job.

Which countries use the Rivet Joint?

The American Air Force flies about 17 of them from Offutt Air Force Base. The British Royal Air Force flies three from RAF Waddington. Both countries use them as part of NATO.

How long can the Rivet Joint fly without stopping?

A normal mission lasts 10 to 12 hours. The plane can fly up to 6,500 kilometers on one trip. That is a very long time to be in the air doing important work!

Frequently Asked Questions

What's a typical Rivet Joint mission like?

A typical RC-135V/W mission is a 10-12 hour orbit at ~10,000 m altitude near (but outside) an adversary's airspace, with the aircraft's 25+ collection operators continuously monitoring + recording RF emissions from ground radar, communications, + air-defence systems. Real-time analysis identifies + locates emitters; recorded data is brought back for deeper exploitation at NSA + GCHQ. Routes are typically pre-planned racetracks of ~300-600 km length, flying parallel to the target country's coast or border. Each mission requires fighter escort (USAF F-15 + F-16 + RAF Typhoon) — the RC-135 is unarmed + a major intelligence asset; loss of one would be a catastrophic intelligence + diplomatic event. The fleet's 17 USAF + 3 RAF aircraft conduct ~6-8 missions per day worldwide in peacetime + 12-15 missions per day during major crises.
