One of the sources added that the aircraft will also be used to objectively monitor the results of tests of various weapons and assess the effectiveness of exercises.

On Friday, January 15, the Russian Foreign Ministry announced Russia's intention to leave the Open Skies Treaty-it allows the military of 33 countries to inspect each other's territory from the air. This decision was a reaction to the withdrawal of the United States from the agreement, as well as problems with agreeing on conditions for further stay in the treaty. Russia, however, may yet reconsider its decision.
