Design
The E-4B is designed to survive an EMP with systems intact, and has state-of-the-art direct fire countermeasures. The E-4B uses analog instruments because they are less susceptible to an EMP. The E-4B is capable of operating with a crew of 48 to 112 people, the largest crew of any aircraft in US Air Force history. With in-flight refueling it is capable of remaining airborne for a considerable period (limited only by consumption of the engines' lubricants). In a test flight for endurance, the aircraft remained airborne and fully operational for 35.4 hours. It takes two fully loaded KC-135 tankers to fully refuel an E-4B.
The E-4B has three operational decks; upper, middle and lower.

Famous quotes containing the word design:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
—Marilyn French (20th century)
