 USA sent Doomsday plane to Europe, the E-6B Mercury aircraft has landed in Iceland and serves as the US Navy's air command post. Before this, last week, the United States Air Force sent four B-52 Stratofortress nuclear bombers to Europe. Now it is known that an E-6B Mercury Doomsday aircraft has landed in Iceland. The arrival of the aircraft in Iceland was reported by the US Air Force European Command on Twitter. The services account notes that the E-6B Mercury is carrying out activities within the command area of responsibility. The Doomsday aircraft is designed to communicate with strategic nuclear powered missile cruisers that carry intercontinental ballistic missiles. These are Ohio class submarines. Each submarine can carry up to 24 Trident 2D5 missiles, which are capable of carrying nuclear warheads. Their maximum launch range is 11,300km and their thermonuclear warhead capacity is 475kT. Instead of Trident 2D5, Ohio submarines can carry 154 BGM-109 Tomahawk cruise missiles with a range of up to 2,500km. The E-6B Mercury is a modification of the Boeing 707-320 passenger jet. It can reach speeds of 981kmh at a cruising speed of 842kmh, 842kmh and is capable of climbing up to 12.8km altitude. The practical range is 11,760kmh. It is worth recalling that on the 22nd of February, Russia withdrew from the Strategic Arms Reduction Treaty. The treaty provided for mutual control between the US and Russia over the number of nuclear weapons and their reduction.
