Overview
- The UK Ministry of Defence said two Russian fighters repeatedly intercepted an RAF RC-135W Rivet Joint on a routine intelligence sortie over the Black Sea in April 2026.
- One Su-35 flew close enough to trigger the Rivet Joint’s emergency systems and disable its autopilot, according to the MoD.
- A separate Su-27 made six passes in front of the British aircraft and came as close as six metres from the Rivet Joint’s nose.
- The aircraft was unarmed and on an international airspace mission supporting NATO’s eastern flank, and the MoD published a short cockpit video and delivered a demarche to the Russian embassy.
- UK officials said the episode is the most dangerous encounter with a Rivet Joint since a 2022 missile near‑miss and linked it to recent Russian submarine activity near undersea infrastructure, warning the tactics raise ISR vulnerability and escalation risks.
