It was created on the basis of the Boeing-747-200 aircraft from the non-purchased one of the airlines of the order and, in fact, was converted into a large mobile "nuclear briefcase" that accompanies the American President and the top military leadership.
All these machines made four pieces in case of nuclear war and they were called "Doomsday planes."
E-4 can stay in the air for a whole week if it is refilled in a timely manner. All systems are protected from the effects of a nuclear explosion; I mean not so much a shock wave, as an electromagnetic pulse, which usually cuts down all electronics.
Given its ceiling in 12 km, it will survive the shock wave if it does not reach the epicenter itself.
When the president flies from the continent, E-4 always sits at the nearby airport as a command post in case of war.
In Hawaii for this, he sits down at the airport at 200 miles from Honolulu. All E-4 carry shelling protection.
The first E-4 began to be assembled in 1973, the engines were initially manufactured by Pratt & Whitney, then switched to General Electric.
This instance was built in 1979, a satellite dish was added to the 1985 aircraft and called E-4B, the other three are called E-4A.
Initially, it was planned to build six working sides and a seventh for research, the budget for this group of aircraft was initially 548 million dollars (1973), and the total cost of each cost 250 million dollars.
In 2005, the US government allocated another 2 billion for five years to improve these aircraft.
The avionics of the E-4B are still of those years, the cabin is analog, so it's a rather complicated aircraft to manage - like the first Boeing-747.
Since the aircraft is equipped with a device for refueling in the air, in theory it can be in the air for up to seven days.
In practice, the most long time he spent in the air without landing 35 hours.
Full refueling of the E-4B requires two KC-135 Stratotanker aircraft tankers, each of which carries tons of fuel from 86, that is, the E-4 refueling goes about 170 tons of kerosene.
E-4 is the most expensive to use in stories United States, each flight hour costs 155 thousand dollars, more than a B-2 or SR-71.
So count the cost to drive to the summit in Davos and back.
In Zurich, after an American aircraft landed around the perimeter, an armored car with a submachine gunner traveled, and all the spectators from the outside of the fence were soon pushed aside by the police.
"The owners of the world" were frightened spotters with cameras, the plane is something super-secret ...
The crew of the E-4 has 112 people (the minimum strength is 48). Due to the fact that people are flying less than in a regular passenger boeing, they need fewer emergency exits, and one of the exits is filled with equipment.
The flight crew consists of an ASF, a co-pilot, a navigator and an engineer.
The entrance to the plane is usually from its own ladder on the lower deck.
E-4 can stay in the air for a very long time, and the limitation is the supply of engine lubricants and the food-water supply for the crew.
E-4 has three decks.
The main working deck and lower in place of the cargo compartment of the commercial 747, there is an electronics and antenna for communication with submarines. The antenna is wound on a coil and in flight is unrolled behind the aircraft, its length is on the order of 8 km.
In the "hump" are places for sitting and resting the crew, there are 8 seats and 6 sleeping shelves.
On the main deck in the bow is the headquarters of the commander, followed by four places for security guards, then a kitchen with ovens and microwaves, where you can cook about a hundred hot dishes during long missions.
Next is the conference and press room, between the kitchen and the conference room, the old projection room, in which the person used to manually change the slides, and now everything is on the plasma, but the room remains. Next is the office, in which sits the so-called combat personnel - about 30 people. They are planners, officers responsible for launching missiles, communication, weather and support.
Here is the scheme for the topic:
Here is a detailed movie:
On the plane there were elements of a commercial aircraft: a spiral staircase to the upper deck, a chandelier and a red rope, like in nightclubs, blocking access to people who are not first class. On board the 12 phone lines, you can call and send a fax to absolutely any telephone number of the entire planet. It is terrible to submit their roaming bill)))
One E-4 always stands on the president’s home base at the Joint Base Andrews, Maryland, and the two first VC-25 (Airforce One) boards are also located there.
On one E-4B, the US Secretary of Defense (secretary of Defense) often moves around the world, and this time the US delegation in Davos was headed by US Vice President Joe Biden.
E-4 is also used in the disaster area as the only decent source of communication. But in Katrina 2005 was not used for some reason ...
Full house at the Zurich Airport observation deck before the E-4B departure.
One E-4 is always ready to fly 24 hours a day with a full crew ready. Apparently, these pump iron, and suddenly "Hey, they drove!" :)
2006 decided to decommission E-2009 from 4 of the year, but 2007 canceled this decision.
The E-4 clock-landing resource will end in 2039, but plan to end service at 2020.
747, of course, beautiful, but our IL-80 is much more beautiful!
Left a mark.
