"The observation flight will be conducted on a Russian An-30B [Clank] from the Brize Norton airport," Sergei Ryzhkov told journalists.
British specialists will be present on the Russian aircraft to monitor the flight.
This is the 13th observation flight conducted by the Russian experts under the treaty.
The Treaty on Open Skies was signed in 1992 in Helsinki and currently applies to 34 countries, including most NATO member states, Russia, Belarus, Ukraine, Georgia, Bosnia and Herzegovina, Sweden and Finland. The treaty establishes a regime of unarmed aerial observation flights over the entire territory of its participants with the aim of boosting transparency of military activities.
