The US “State Department acknowledged that the crew of the destroyer USS Donald Cook has been gravely demoralized ever since their vessel was flown over in the Black Sea by a Russian Sukhoi-24 (Su-24) fighter jet which carried neither bombs nor missiles but only an electronic warfare device” reports the Voltaire Network
On 10 April 2014, the USS Donald Cook entered the waters of the Black Sea and on 12 April a Russian Su-24 tactical bomber flew over the vessel triggering an incident that, according to several media reports, completely demoralized its crew. The Pentagon actually issued a statement protesting the “unprofessional” act of the Russians..
The USS Donald Cook (DDG-75) is a 4th generation guided missile destroyer whose key weapons are Tomahawk cruise missiles with a range of up to 2,500 kilometers, and capable of carrying nuclear explosives. It is equipped with the most recent Aegis Combat System - an integrated naval weapons systems which can link together the missile defense systems of all vessels embedded within the same network, so as to ensure the detection, tracking and destruction of hundreds of targets at the same time. In addition, the USS Donald Cook is equipped with 4 large radars, whose power is comparable to that of several stations. For protection, it carries more than fifty anti-aircraft missiles of various types.
Meanwhile, the Russian Su-24 that buzzed the USS Donald Cook carried neither bombs nor missiles but only a basket mounted under the fuselage, which contained a Russian electronic warfare device called Khibiny.
As the Russian jet approached the US vessel, the electronic device disabled all radars, control circuits, systems, information transmission, etc. on board the US destroyer. The Russian Su-24 then simulated a missile attack against the USS Donald Cook, which was left literally deaf and blind. As if carrying out a training exercise, the Russian aircraft - unarmed - repeated the same maneuver 12 times before flying away.
After that, the 4th generation destroyer immediately set sail towards a port in Romania. Since that incident, no US ship has ever approached Russian territorial waters again. According to some specialized media, 27 sailors from the USS Donald Cook requested to be relieved from active service. (Sourced from: Voltaire Network | 8 November 2014
