British surveillance aircraft patrols near Ukraine border

A British RC-135 ‘Rivet Joint’, an electronic surveillance aircraft, has conducted a patrol over Romania close to the border of Ukraine.

The aircraft was there to conduct electronic surveillance and gather intelligence on Russian forces inside Ukraine.

This isn’t a new occurrence, in fact it is quite routine. The UK has long been gathering intelligence about Russian forces since long before the invasion of Ukraine and it should be noted that these flights are designed to be visible so that the public and Russia know they’re happening.

If it was a secret, I would not know. Also, for those remarking ‘this isn’t new’, that’s right but people only know this happens often because it is reported often.

What does the RC-135W do?

According to the Royal Air Force website, the RC-135W Rivet Joint is a dedicated electronic surveillance aircraft that can be employed in all theatres on strategic and tactical missions. Its sensors ‘soak up’ electronic emissions from communications, radar and other systems.

“RC-135W Rivet Joint employs multidiscipline Weapons System Officer (WSO) and Weapons System Operator (WSOp) specialists whose mission is to survey elements of the electromagnetic spectrum in order to derive intelligence for commanders.”

The Royal Air Force say that Rivet Joint has been deployed extensively for Operation Shader and on other operational taskings. It had been formally named Airseeker, but is almost universally known in service as the RC-135W Rivet Joint.

Some general uses of the RC-135W include:

• Signal Intelligence (SIGINT): The aircraft collects electronic signals, such as communications, radar, and other systems, to gather intelligence on adversaries’ capabilities and intentions. This information is crucial for understanding the operational environment and making well-informed decisions.
• Support to Operations: The RC-135W has been used in various operations, such as Operation Shader, which is the UK’s contribution to the ongoing military intervention against the Islamic State in Iraq and Syria. The aircraft supports these operations by collecting intelligence on enemy forces, infrastructure, and strategies.
• Strategic Deterrence: By conducting visible reconnaissance flights near areas of interest, the UK sends a clear message to potential adversaries that their activities are being closely monitored. This serves as a deterrent, helping to maintain regional stability and prevent conflicts.
• Support to Diplomacy: Intelligence gathered by the RC-135W can play a crucial role in informing diplomatic efforts and shaping foreign policy. By providing accurate and timely information, the aircraft helps decision-makers navigate complex geopolitical situations.

The UK operates three RC-135W Rivet Joint aircraft, which are versatile and essential assets for maintaining situational awareness and supporting various military and diplomatic initiatives.
