U.S. to Conduct Observation Flight over Russia as Part of Treaty on Open Skies

The United States will conduct an observation flight over the Russian Federation on August 19-24 as part of the Treaty on Open Skies, according to Sergei Ryzhkov, the head of Russia’s Nuclear Risk Reduction Center.

The observation flight will be conducted by a U.S. Air Force OC-135B Open Skies observation aircraft.

“During the flight along the agreed route, Russian specialists on board the aircraft will monitor the strict observance of the agreed flight parameters and application of the monitoring equipment stipulated by the contract”, said a statement by the Russian Ministry of Defense.

The OC-135B, a modified WC-135 Constant Phoenix special-purpose aircraft, flies unarmed observation flights over participating parties of the Treaty on Open Skies.
