The UK Defence Secretary John Healey's government plane lost its GPS signal while flying near the Russian border, according to The Times.
On May 21, the Dassault Falcon 900LX experienced a satellite signal cut. The pilot used inertial navigation for three hours.
This incident follows a similar GPS loss in March involving Healey's predecessor Grant Shapps. Both planes lacked electronic warfare protection.
Planned upgrades for the aircraft are expected to be completed by 2026.
