As one of the Aerospace Forces' representatives revealed, 'frequent missions of the interceptors for the last 10 days have been triggered by stepped-up flights of the NATO's unmanned aerial vehicles at the Crimean air frontiers. Duty shifts of interceptors are carried out in full combat readiness, while pilots go on duty in partial pressure suits'.
And the so-called stealth technologies applied in the NATO's surveillance drones do not deter Russian radars from detecting them, they provide interceptors with accurate targets.
In course of the interception Russian fighters demonstrate suspended missile armament to trespassers and readiness to apply it. Such a demonstration is enough for the NATO's spies to change the route away from Russian borders.
