A Royal Air Force aircraft carrying UK Defence Secretary John Healey experienced GPS signal jamming during a three-hour flight from Estonia back to the United Kingdom, according to reports.

The electronic interference occurred as Healey was returning from visiting British troops stationed in Estonia. Pilots aboard the RAF jet were forced to rely on alternative navigation systems after the plane's GPS was disabled during the flight.

The incident took place near the Russian border region, though the exact location and timing of the jamming have not been specified by official sources. The flight was able to continue safely using backup navigation methods.

GPS jamming has become an increasingly common occurrence in airspace near Russia's borders, affecting both military and civilian aircraft. The practice involves transmitting radio signals that interfere with or block GPS receivers, forcing aircraft to use alternative navigation systems.

Estonia, where Healey had been visiting UK forces, shares a border with Russia and has been among the NATO countries experiencing increased electronic interference in recent years. British troops are stationed in the Baltic nation as part of NATO's enhanced forward presence mission.

The UK Ministry of Defence has not immediately provided additional details about the incident or confirmed whether it has filed any formal complaints regarding the interference.
