Boeing 747

Boeing launched the 747 Program in 1966 with an order from Pan American World Airlines. The 747 entered commercial service in 1970; the early 747 family included the -100, -200 and -300 models, commonly referred to as the Classics. The

747-400 is currently the only model in production, and it is the best-selling member of the 747 family. Boeing thoroughly redesigned the 747 with the -400 model, making major aerodynamic improvements, adding winglets to improve fuel efficiency, incorporating new avionics, installing a new flight deck and providing the latest in-flight entertainment systems.

The 747-400 flight deck replaced the analog systems of the 747 Classic with digital avionics, reducing the number of lights, gauges and switches from 971 to 365. Programmable displays and simpler cockpit procedures also reduced the workload in

Delivered until October 2001, 566 Boeing 747-400’s (summary 15 December 2001 )

The E-4 is configured as an AABNCP (Advanced Airborne National Command Post); its upper deck serves as a crew rest area; the main deck holds the President of the USA (as Commander-in-chief of US Forces) and his battle staff in five compartments; the flight crew section, the NCA (National Command Authority) work area, a conference room, battle staff, and C³I (command, control, communication and intelligence) area; the aircraft is shielded against EMP. One example is never far away whenever the President travels overseas. The first E-4 was delivered in late 1974, to the 1^st ACCS/55^th Wing at Offutt AFB, NE.

The Boeing VC-25A named Air Force One (only when the President is on board) is configured for long-range special air mission (SAM) transport for the President of the United States; the aircraft is shielded against EMP (electromagnetic pulse) and carries MCS (mission communications system) three operators, and provision for worldwide secure communication; normal accommodation is for up to 70 passengers and 23 crew members.

The VC-25A is the airborne equivalent of the White House’s Oval Office with:

The first operational mission of the VC-25A was made on 6 September 1990, taking President George Bush sr. to Topeka , Kansas , and Tallahassee , Florida . The following day, the Air Force One made its first overseas trip, taking Bush sr. to Helsinki , Finland .

The high-energy laser weapon system will shoot down theater ballistic missiles while they still are over the enemy’s own territory. The Airborne Laser (ABL) weapon system will operate at altitudes above the clouds where it can acquire and track missiles in boost flight, and then accurately point and fire the laser with such energy that the missile is destroyed before it can do any harm.

The Islamic Republic of Iran Air Force has eight Boeing 747-131F and four 747-2J9F, some of them can be used as aerial tankers, and they have the same Flying Boom under the rear fuselage.
