A Royal Air Force (RAF) electronic surveillance aircraft, the RC-135W Rivet Joint, conducted a patrol over Russian territory in Kaliningrad.
According to a report from the UK Defence Journal, these flights are part of regular allied intelligence-gathering missions along NATO’s eastern border.
The UK has been conducting such patrols for years, maintaining constant surveillance of Russian military activity long before the 2022 invasion of Ukraine.
While British surveillance activity over the Baltic Sea has always been routine, the tempo of these flights has increased significantly amid the ongoing conflict in Ukraine.

According to the RAF website, the RC-135W Rivet Joint is an aircraft dedicated to electronic surveillance, capable of operating in all theaters on strategic and tactical missions. Its sensors capture electronic emissions from communications systems, radars, and other devices.
“The RC-135W Rivet Joint employs multidisciplinary Weapons Systems Officers (WSO) and Weapons Systems Operators (WSOp), whose mission is to monitor elements of the electromagnetic spectrum to provide intelligence to commanders.”
Although described as a “spy plane,” Rivet Joint missions are designed to be overt, and their flight tracks are visible on civilian flight-tracking platforms, providing transparency about the aircraft’s presence and allowing observers to verify the frequency of operations in the area.
It is worth noting that U.S. reconnaissance aircraft also operate in the region as part of NATO’s coordinated intelligence and deterrence efforts.
