The presidential fleet is getting an upgrade with two modern Boeing 747s to serve as Air Force One.Though former U.S. president Donald Trump changed the plane's color scheme and claims he shaved US$1.5 billion off the program's cost, according to reports, the first president to fly in the planes will be Joe Biden.According to the War Zone, the new jets are larger Boeing 747-8is that will feature more efficient next generation engines and have a range of 5,900 nautical miles.The planes will lack some features of their predecessors, including inflight refueling, the result of cost-cutting efforts by the Air Force and Trump administration.RUNDOWN SHOWS:1.

Presidents Donald Trump and Joe Biden boarding Air Force OneVOICEOVER (in English): "The presidential fleet is getting an upgrade with two modern Boeing 747s to serve as Air Force One.""Former U.S. president Donald Trump redesigned Air Force One's exterior with the American flag colors of red, white and blue.""The future Air Force One aircraft are Boeing 747-8is. Their Air Force designation is VC-25B.""They will replace the currently serving VC-25As.""The new jets are larger and more efficient, though they will carry the same number of passengers 71 according to the War Zone.""Currently, the president's suite and office are housed at the very front of the aircraft."In the event of an emergency, Air Force One has a staff doctor and houses a medical suite that can function as an operating room at a moment's notice.""Air Force One also has quarters for those who accompany the president, including travelling press who sit toward the rear of the plane.""As it is able to refuel mid-air, Air Force One effectively has unlimited range and can stay in the air indefinitely.""As part of its advanced security systems, the jet is equipped with chaff and flare dispensers that allow it to evade enemy missiles.""The new Air Force planes will be able to fly 5,900 nautical miles non-stop, meaning they can fly to any populated continent directly from Washington.""Their next-generation General Electric engines are more fuel-efficient than those on the current Air Force One aircraft." "But due to cost-saving efforts by Trump and the Air Force the replacement program will only cost US$5.3 billion the planes will lack some features of their predecessors, including the ability to aerial refuel in air.""And though Trump kept a model of the new jets in the Oval Office, Joe Biden will be the first president to use them when they enter service in 2024."SOURCES: Defense One, War Zone, BBC News, Defense Newshttps://www.defenseone.com/business/2020/04/owners-manual-trumps-new-air-force-one-cost-84-million/164651/https://www.defenseone.com/business/2017/09/searching-1-billion-inside-pentagons-struggle-match-trumps-air-force-one-boast/140852/https://www.thedrive.com/the-war-zone/22351/usaf-offers-new-details-about-new-air-force-ones-but-doesnt-back-up-trumps-cost-cutting-claimshttps://ichef.bbci.co.uk/news/976/cpsprodpb/1682F/production/_107370229_air_force_one_new_v1_-3x976-nc.png
