On May 21, a Royal Air Force jet carrying John Healey, the United Kingdom's Defence Secretary, lost its satellite navigation for the entire three-hour flight home from Estonia. British officials say the cause was Russian electronic warfare. It is at least the second time in two years that Russia has jammed the signal of an aircraft carrying a sitting UK defence chief.
What Happened Over the Baltic
Healey was returning to Britain after visiting UK troops stationed in southeast Estonia, where the NATO ally hosts a British-led brigade on Russia's border. His aircraft, a Dassault Falcon 900LX, had its GPS disabled shortly after takeoff and stayed dark for the rest of the flight.
The crew switched to backup inertial navigation systems, which calculate position without satellites. The jamming also caused parts of the cockpit dashboard to malfunction, according to The Times, which first reported the incident on May 24. One of the pilots said it was a rare event he had not seen in a long time.
On board were political and military advisers, a lieutenant general, two photographers and a journalist. Passengers were told the plane could fly on safely. A British defence source called it "reckless" Russian interference and said the RAF is well prepared for these conditions. The same source acknowledged it is unclear whether Healey's plane was deliberately targeted, and noted the government jet's route was visible the entire time on public flight-tracking websites.
"The UK's commitment to Estonia is unshakeable. We are exercising together to deter Russian aggression and keep Estonia and the alliance secure."

This Has Happened Before
Russia did not invent this tactic for Healey. GPS interference around the Baltic has been near-constant since the full-scale invasion of Ukraine in 2022, concentrated near Kaliningrad, the heavily militarized Russian exclave between Poland and Lithuania. Estonia, Latvia, Lithuania and Finland have all reported a steady rise in disrupted flights.
It has reached senior officials before. A military jet carrying Spanish Defence Minister Margarita Robles was hit by GPS interference last September near Kaliningrad. European Commission President Ursula von der Leyen's plane encountered similar interference over Bulgaria. In 2024, Russia jammed an RAF aircraft carrying Healey's predecessor as defence secretary, Grant Shapps.
The incident also follows a series of dangerous Russian intercepts of British surveillance flights over the Black Sea, which UK officials called the most serious confrontations between Russian and British aircraft since 2022. The pattern points one direction: Russia is probing how far it can push NATO members in international airspace, and meeting little resistance when it does.
Why a Shrug Is the Wrong Answer
British officials were quick to stress that the flight was never in real danger, and that is accurate. The RAF trains for degraded navigation, and the plane landed safely. The risk is not to one well-equipped military jet.
The risk is to everyone else in that airspace. Commercial airliners crossing the Baltic depend on the same satellite signals, and pilots have reported losing navigation and receiving false position data over the region. Russia is running an open-ended electronic warfare campaign across international and allied airspace, and the people absorbing the danger are civilian passengers and crews who never signed up for it.
Treating each case as an isolated nuisance is how the campaign continues. A jammed defence minister's plane is cheap, deniable and, so far, consequence-free for Moscow.
Healey flew to Estonia to demonstrate that NATO's deterrence is real. Deterrence depends on consequences, and Russia jammed a NATO cabinet minister's aircraft for three hours to a public response of one anonymous quote calling it reckless. Until that calculation changes, Russia has no reason to stop.
