Reconnaissance aircraft in the context of Lockheed U-2

Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking enemy installations or a concentration of enemy troops or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel.

Historically, military aircraft have included lighter-than-air balloons carrying artillery observers; lighter-than-air airships for bombing cities; various sorts of reconnaissance, surveillance, and early warning aircraft carrying observers, cameras, and radar equipment; torpedo bombers to attack enemy vessels; and military air-sea rescue aircraft for saving downed airmen. Modern aerial warfare includes missiles and unmanned aerial vehicles. Surface forces are likely to respond to enemy air activity with anti-aircraft warfare.

Military aviation is the design, development and use of military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift (air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft.

Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers.

The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The commission approached NAA to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, NAA proposed the design and production of a more modern fighter. The prototype NA-73X airframe was completed on 9 September 1940, 102 days after contract signing, achieving its first flight on 26 October.

The Mustang was designed to use the Allison V-1710 engine without an export-sensitive turbosupercharger or a multi-stage supercharger, resulting in limited high-altitude performance. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraft and fighter-bomber (Mustang Mk I). In mid 1942, a development project known as the Rolls-Royce Mustang X, replaced the Allison engine with a Rolls-Royce Merlin 65 two-stage inter-cooled supercharged engine. During testing at Rolls-Royce's airfield at Hucknall in England, it was clear the engine dramatically improved the aircraft's performance at altitudes above 15,000 ft (4,600 m) without sacrificing range. Following receipt of the test results and after further flights by USAAF pilots, the results were so positive that North American began work on converting several aircraft developing into the P-51B/C (Mustang Mk III) model, which became the first long-range fighter to be able to compete with the Luftwaffe's fighters. The definitive version, the P-51D, was powered by the Packard V-1650-7, a license-built version of the two-speed, two-stage-supercharged Merlin 66, and was armed with six .50 caliber (12.7 mm) AN/M2 Browning machine guns.

The Dassault Mirage IV is a supersonic strategic bomber and deep-reconnaissance aircraft developed and produced by the French aircraft manufacturer Dassault Aviation.

Development of the Mirage IV began in the mid-1950s in response to a need for a supersonic carrier aircraft for France's independent nuclear deterrent. Dassault competed with other aircraft manufacturers, such as Sud Aviation and Nord Aviation, to have its proposal built, which was viewed as being both cheaper and simpler to develop in part due to it drawing upon the earlier Dassault Mirage III fighter. While originally intended as a dedicated bomber, a reconnaissance variant would also be developed. The first prototype, Mirage IV 01, performed its maiden flight on 17 June 1959; it set a new world record for speed over a 1000-kilometre closed circuit of 1,822 km/h (1,132 mph) on 19 September 1960. The first production-standard aircraft was completed during December 1963 and the Mirage IV entered service with the French Air Force in October 1964.

A multirole combat aircraft is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses.

An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. Aircraft that are capable of being or are employed as both "standard" air superiority fighters and as interceptors are sometimes known as fighter-interceptors. In the post-World War II jet age, there are two general classes of interceptor: light fighters, designed for high performance over short range; and heavy fighters, which are intended to operate over longer ranges, in contested airspace and adverse meteorological conditions. While the second type was exemplified historically by specialized night fighter and all-weather interceptor designs, the integration of mid-air refueling, satellite navigation, on-board radar, and beyond visual range (BVR) missile systems since the 1960s has allowed most frontline fighter designs to fill the roles once reserved for specialized night/all-weather fighters.

For daytime operations, conventional light fighters have normally filled the interceptor role. Day interceptors have been used in a defensive role since World War I, and are perhaps best known from major actions like the Battle of Britain, when the Supermarine Spitfire and Hawker Hurricane were part of a successful defensive strategy. However, dramatic improvements in both ground-based and airborne radar gave greater flexibility to existing fighters and few later designs were conceived as dedicated day interceptors. Exceptions include the Messerschmitt Me 163 Komet, which was the only rocket-powered, crewed military aircraft to see combat. To a lesser degree, the Mikoyan-Gurevich MiG-15, which had heavy armament specifically intended for anti-bomber missions, was also a specialized day interceptor.

The DFS 228 was a rocket-powered, high-altitude reconnaissance aircraft designed by the Deutsche Forschungsanstalt für Segelflug (DFS - "German Research Institute for Sailplane Flight") during World War II. By the end of the war, the aircraft had only flown in the form of two unpowered prototypes.

The Lockheed SR-71 "Blackbird" is a retired long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft that was developed and manufactured by the American aerospace company Lockheed Corporation. Its nicknames include "Blackbird" and "Habu".

The SR-71 was developed in the 1960s as a black project by Lockheed's Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the SR-71's innovative concepts. Its shape was based on the Lockheed A-12, a pioneer in stealth technology with its reduced radar cross section, but the SR-71 was longer and heavier to carry more fuel and a crew of two in tandem cockpits. The SR-71 was revealed to the public in July 1964 and entered service in the United States Air Force (USAF) in January 1966.

A maritime patrol aircraft (MPA), also known as a patrol aircraft, maritime reconnaissance aircraft, maritime surveillance aircraft, or by the older American term patrol bomber, is a fixed-wing aircraft designed to operate for long durations over water in maritime patrol roles — in particular anti-submarine warfare (ASW), anti-ship warfare (AShW), and search and rescue (SAR).

In addition to dedicated airframes, mid-size and large business jets have been modified for MPA missions, offering rapid deployment, extended range, long endurance, and lower life-cycle costs.

The Boeing RC-135 is a family of large reconnaissance aircraft built by Boeing and modified by a number of companies, including General Dynamics, Lockheed, LTV, E-Systems, L3Harris Technologies, and used by the United States Air Force and Royal Air Force to produce theater and national level intelligence with near real-time on-scene collection, analysis and dissemination capabilities.

Based on the Boeing C-135 Stratolifter airframe, various types of RC-135s have been in service since 1961. Unlike the KC-135, which is recognized by Boeing as the Model 717, most of the current RC-135 fleet, with the exception of the RAF's RC-135Ws, is internally designated as the Model 739 by the company. Many variants have been modified numerous times, resulting in a large variety of designations, configurations, and program names.

The Tupolev Tu-22 (Air Standardization Coordinating Committee name: Blinder) was the first supersonic bomber to enter production in the Soviet Union. Manufactured by Tupolev, the Tu-22 entered service with Long-Range Aviation and Soviet Naval Aviation in the 1960s.

The aircraft was a disappointment, lacking both the speed and range that had been expected. It was also a difficult design to fly and maintain. It was produced in small numbers, especially compared to the Tupolev Tu-16 it was designed to replace. The aircraft was later adapted for other roles, notably as the Tu-22R reconnaissance aircraft and as a carrier for the long-range Kh-22 antiship missile.

The British Aircraft Corporation TSR-2 was a cancelled supersonic strike and reconnaissance aircraft designed by the British Aircraft Corporation (BAC). It was under development throughout the late 1950s and early 1960s for the Royal Air Force (RAF); the TSR-2 designation came from "Tactical Strike and Reconnaissance, Mach 2".

The TSR-2 arose from the issuing of General Operational Requirement 339 (GOR.339) in November 1956, which sought a successor to the English Electric Canberra that would perform both conventional and tactical nuclear weapons delivery, be able to penetrate well-defended frontline areas at low altitudes and very high speeds, and attack high-value targets in rear areas. Another intended combat role was to provide high-altitude, high-speed stand-off, side-looking radar and photographic imagery and signals intelligence, aerial reconnaissance. On 1 January 1959, the project received its official go-ahead; early work was undertaken by Vickers-Armstrong in cooperation with English Electric, before Britain's aircraft industry underwent consolidation to create BAC. However, as some contributing manufacturers were employed directly by the Ministry rather than through BAC, this led to communication difficulties and cost overruns. On 27 September 1964, test pilot Roland Beamont performed the type's maiden flight.
