Air Force One is the official air traffic control designated call sign for a United States Air Force aircraft carrying the president of the United States. In common parlance, the term is used to denote U.S. Air Force aircraft modified and used to transport the president and a metonym for the primary presidential aircraft, VC-25, although it can be used to refer to any Air Force aircraft the president travels on.
A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again.
The McDonnell Douglas KC-10 Extender is an American tanker and cargo aircraft operated by the United States Air Force (USAF). A military version of the three-engine DC-10 airliner, the KC-10 was developed from the Advanced Tanker Cargo Aircraft Program. It incorporates military-specific equipment for its primary roles of aerial refueling and transport. It was developed to supplement the KC-135 Stratotanker following experiences in Southeast Asia and the Middle East. The KC-10 was the second McDonnell Douglas transport aircraft to be selected by the Air Force following the C-9. A total of 60 KC-10s were produced for the USAF. The Royal Netherlands Air Force operated two similar tankers designated KDC-10 that were converted from DC-10s.
The Boeing C-32 is the United States Air Force designation for variants of the Boeing 757 in military service. Two variants exist, filling different parts of the military passenger transport role. The C-32A serves the Special Air Mission, providing executive transport and broad communications capabilities to senior political officials, while the C-32B Gatekeeper provides clandestine airlift to special operations and global emergency response efforts, a role known as "covered air".
The Airbus A330 Multi Role Tanker Transport (MRTT) is a European aerial refuelling and military transport aircraft based on the civilian Airbus A330. A total of 16 countries have placed firm orders for approximately 68 aircraft, of which 51 had been delivered by 30 November 2020. A version of the A330 MRTT, the EADS/Northrop Grumman KC-45, was selected by the United States Air Force for its aerial tanker replacement programme, but the programme was cancelled.

The General Command of the Air Force, also referred to as the Islamic Emirate Air Force and the Afghan Air Force, is the air force branch of the Afghan Armed Forces.
The P-800 Oniks, marketed in export as the Yakhont, is a Soviet / Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr. Its GRAU designation is 3M55, the air launched Kh-61 variant also exists. The missile has the NATO codename SS-N-26 "Strobile". Development commenced in 1983, and in the 1990s the anti-ship missile was tested on the Project 1234.7 ship. In 2002 the missile passed the whole range of trials and was commissioned. It is reportedly a replacement for the P-270 Moskit, and possibly also of the P-700 Granit.
The Czech Air Force is the air force branch of the Army of the Czech Republic. Along with the Land Forces, the Air Force is the major Czech military force. With traditions of military aviation dating back to 1918, the Czech Air Force, together with the Slovak Air Force, succeeded the Czechoslovak Air Force in 1993. On 1 July 1997, the 3rd Tactical Aviation Corps and the 4th Air Defence Corps of the Czech Army were merged to form an independent Air Force Headquarters.
The Hungarian Air Force, is the air force branch of the Hungarian Defence Forces.
The Boeing KC-46 Pegasus is an American military aerial refueling and strategic military transport aircraft developed by Boeing from its 767 jet airliner. In February 2011, the tanker was selected by the United States Air Force (USAF) as the winner in the KC-X tanker competition to replace older Boeing KC-135 Stratotankers. The first aircraft was delivered to the Air Force in January 2019. The Air Force intends to procure 179 Pegasus aircraft by 2027.
The Aerion AS2 was a proposed supersonic business jet that was being developed by Aerion Corporation. In May 2014, it was announced that the Aerion AS2 would be part of a larger Aerion SBJ redesign, which aimed for release after a seven-year developmental period. Aerion partnered with Airbus in September the same year. In December 2017, Airbus was replaced by Lockheed Martin. Its General Electric Affinity engine was unveiled in October 2018. In February 2019, Boeing replaced Lockheed Martin. Development stopped when Aerion ceased operations in May 2021.
The PAK VTA ) is a Russian next-generation heavy military transport aircraft, currently under development by Ilyushin.
The Lockheed Martin X-59 Quesst, sometimes styled QueSST, is an American experimental supersonic aircraft being developed at Skunk Works for NASA's Low-Boom Flight Demonstrator project. Preliminary design started in February 2016, with the X-59 to be delivered to NASA in 2021 for flight testing in 2023. It is expected to cruise at Mach 1.42 at an altitude of 55,000 ft (16,800 m), creating a low 75 Perceived Level decibel (PLdB) thump to evaluate supersonic transport acceptability.
Boom Technology, Inc. is an American company designing a supersonic airliner named the Boom Overture. The company is also developing a one-third-scale demonstrator: the Boom XB-1 Baby Boom.
The Boeing–Saab T-7 Red Hawk, initially known as the Boeing T-X, is an American/Swedish supersonic advanced jet trainer produced by Boeing with Saab. In September 2018, the United States Air Force (USAF) picked it for the T-X program to replace the Northrop T-38 Talon as the service's advanced jet trainer.
The Boom Overture is a proposed Mach 1.7, 64–80 passenger supersonic airliner with 4,250 nmi of range, which is planned to be introduced in 2029 by Boom Technology. The company claims that with 500 viable routes, there could be a market for 1,000 supersonic airliners with business class fares. It had gathered 76 commitments by December 2017. The aircraft is planned to have a delta wing configuration, but will be built with composite materials. Following a redesign revealed in 2022 it is intended to be powered by four dry (non-afterburning) 35,000 lbf (160 kN) turbofans. Regulations for takeoff noise or overland boom can be met or changed.
Hermeus Corporation is an American startup company from Atlanta, Georgia focused on the development of commercial hypersonic aircraft. Their mission is to radically accelerate air travel through the development of multiple dual-use Mach 5 capable aircraft.
