yeah the delay isn't classified, it's physics... 2 seconds is about right considering you lose about 440ms from the aircraft to the satellite and down to the ground station and another 40-60ms on the terrestrial ride back to NV from one of the relay sites plus another 10-20ms for processing delays. then the same delays on the forward link for commands to the aircraft. all said, round trip, that's a little over a second of unavoidable delay, not to mention pilot reaction time etc...
