Escort fighter in the context of Loiter (aeronautics)

The McDonnell Douglas F/A-18 Hornet is an all-weather supersonic, twin-engined, carrier-capable, multirole combat aircraft, designed as both a fighter and ground attack aircraft (hence the F/A designation). Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the YF-17 that lost against the YF-16 in the United States Air Force's lightweight fighter program. The United States Navy selected the YF-17 for the Navy Air Combat Fighter program, further developed the design and renamed it F/A-18; the United States Marine Corps would also adopt the aircraft. The Hornet is also used by the air forces of several other nations, and formerly by the U.S. Navy's Flight Demonstration Squadron, the Blue Angels.

The F/A-18 was designed to be a highly versatile aircraft due to its avionics, cockpit displays, and excellent aerodynamic characteristics for high angles-of-attack maneuvers, with the ability to carry a wide variety of weapons. The aircraft can perform fighter escort, fleet air defense, suppression of enemy air defenses, air interdiction, close air support, and aerial reconnaissance. Its versatility and reliability have proven it to be a valuable carrier asset.

The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the German aircraft manufacturer Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the Luftwaffe's fighter force during the Second World War. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation.

The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor. However, later models were developed to fulfill multiple tasks, serving as bomber escort, fighter-bomber, day-, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft. It was one of the most advanced fighters when it first appeared, being furnished with an all-metal monocoque construction, a closed canopy, retractable landing gear, and powered by a liquid-cooled, inverted-V12 aero engine. First flown on 29 May 1935, the Bf 109 entered operational service during 1937; it first saw combat during the Spanish Civil War.

The Republic P-47 Thunderbolt (nicknamed the "Jug") is a World War II-era fighter aircraft produced by the American company Republic Aviation from 1941 through 1945. One of the main United States Army Air Forces (USAAF) fighters, it found success in the European and Pacific theaters as an escort fighter well-suited to high-altitude air-to-air combat. It also served as the foremost American fighter-bomber in the ground-attack role.

The P-47 was noted for its firepower: its primary armament was eight .50-caliber machine guns, and it could carry 5-inch rockets or a bomb load of 2,500 lb (1,100 kg). When fully loaded, the aircraft weighed up to 8 tons, making it one of the heaviest fighters of the war. It was also noted for its ability to remain airworthy with battle damage.

The Lockheed P-38 Lightning is an American single-seat, twin-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps (USAAC) by the Lockheed Corporation, the P-38 incorporated a distinctive twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium and heavy bombers, or even other P-38s equipped with bombs, to their targets. Some 1,200 Lightnings, about 1 of every 9, were assigned to aerial reconnaissance, with cameras replacing weapons to become the F-4 or F-5 model; in this role it was one of the most prolific recon airplanes in the war. Although it was not designated a heavy fighter or a bomber destroyer by the USAAC, the P-38 filled those roles and more; unlike German heavy fighters crewed by two or three airmen, the P-38, with its lone pilot, was nimble enough to compete with single-engined fighters.

The P-38 was used most successfully in the Pacific and the China-Burma-India theaters of operations as the aircraft of America's top aces, Richard Bong (40 victories), Thomas McGuire (38 victories), and Charles H. MacDonald (27 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the introduction of large numbers of P-51D Mustangs toward the end of the war. Unusually for an early-war fighter design, both engines were supplemented by turbosuperchargers, making it one of the earliest Allied fighters capable of performing well at high altitudes. The turbosuperchargers also muffled the exhaust, making the P-38's operation relatively quiet. The Lightning was extremely forgiving in flight and could be mishandled without incident in many ways, but the initial rate of roll in early versions was low relative to other contemporary fighters; this was addressed in later variants with the introduction of hydraulically boosted ailerons. The smaller and more streamlined P-51 was significantly faster in a dive, which led to the P-51 replacing the P-38 in most European fighter groups by mid-1944. The P-38 was the only American fighter aircraft in large-scale production throughout American involvement in the war, from the Attack on Pearl Harbor to Victory over Japan Day.
