A Russian fighter jet flew within six metres of an unarmed Royal Air Force (RAF) spy plane traveling at 500mph over the Black Sea. This encounter was one of two mid-air incidents last month that Defence Secretary John Healey described as “dangerous and unacceptable.”
Dangerous Encounters in International Airspace
In mid-April, a Russian Su-27 jet performed six passes in front of an RAF Rivet Joint aircraft, flying dangerously close to the plane’s nose. Officials warned that such maneuvers risked a collision that could have triggered a diplomatic crisis between the two nations.
A second incident occurred during the same period when a Russian Su-35 jet flew close enough to the British aircraft to trigger its emergency systems. This interaction disabled the plane’s autopilot while it was conducting a surveillance mission over international airspace.
Escalating Military Tensions
The Ministry of Defence stated on Wednesday that these events represent the most dangerous Russian actions against a Rivet Joint aircraft since a missile was fired over the Black Sea in 2022.

“This incident is another example of dangerous and unacceptable behaviour by Russian pilots, towards an unarmed aircraft operating in international airspace,” Healey said. “These actions create a serious risk of accidents and potential escalation.”
Broader Russian Activity in Europe
The incidents over the Black Sea coincide with increased Russian military activity across Europe. On Wednesday, air traffic at Vilnius airport was temporarily suspended and Lithuanian politicians sheltered underground following a drone violation of the country’s airspace.
Russia’s ambassador to the UN claimed Moscow had information that Ukraine planned to launch military drones from the Baltic states, including Latvia. Latvian officials dismissed these claims as “pure fiction.”
Maritime activity has also risen, with two Russian frigates escorting oil tankers and a suspected arms shipment through the Dover strait and North Sea last month. This activity required a month-long surveillance patrol by the Royal Navy.
Healey revealed that the UK tracked three Russian submarines that loitered over critical undersea infrastructure in the North Atlantic for one month before departing.
UK Commitment to Nato
Defence Secretary John Healey praised the RAF crew for their bravery and professionalism in continuing their mission despite the risks. He emphasized that the UK remains committed to its allies.

“Let me be very clear: This incident will not deter the UK’s commitment to defend Nato, our allies and our interests from Russian aggression,” Healey stated.
Given the current trajectory, future encounters could lead to further diplomatic friction or may prompt increased Nato patrol presence to mitigate the risk of accidents.
Frequently Asked Questions
What happened to the RAF spy plane over the Black Sea?
The aircraft experienced two incidents in mid-April: an Su-27 jet made six passes close to its nose and an Su-35 jet flew close enough to disable the plane’s autopilot and trigger emergency systems.
What is an RAF Rivet Joint?
This proves an unarmed spy plane with a crew of up to 30 that performs electronic surveillance at ranges of about 150 miles, often as part of Nato patrols.
What other Russian military activities were reported?
Reports include a drone violating Lithuanian airspace, Russian frigates escorting shipments through the North Sea and Dover strait, and three Russian submarines loitering over critical undersea infrastructure in the North Atlantic.
Do you believe increased surveillance patrols are the most effective way to deter these mid-air encounters?
