The Tu-214R is a Russian ISR (Intelligence Surveillance Reconnaissance) aircraft. In other words, a quite advanced spyplane.
As we have already explained here in the past, it is a special mission aircraft equipped with all-weather radar systems and electro optical sensors that produce photo-like imagery of a large parts of the ground: these images are then used to identify and map the position of the enemy forces, even if these are camouflaged or hidden.
The aircraft is known to carry sensor packages to perform ELINT (Electronic Intelligence) and SIGINT (Signal Intelligence) missions: the antennae of the Tu-214R can intercept the signals emitted by the enemy systems (radars, aircraft, radios, combat vehicles, mobile phones etc) so as it can build the EOB (Electronic Order of Battle) of the enemy forces: where the enemy forces are operating, what kind of equipment they are using and, by eavesdropping into their radio/phone communications, what they are doing and what will be their next move.
The aircraft is built by KAPO (Kazan Aircraft Production Association) and flown from the company’s airfield in Kazan.
