Radius of action

Last updated

Radius of action, combat radius, or combat range in military terms, refers to the maximum distance a ship, aircraft, or vehicle can travel away from its base along a given course with normal load and return without refueling, allowing for all safety and operating factors. [1]

A given aircraft's radius of action varies according to the altitude of its flight plan, amount of weight (ordnance in a military context) it is carrying, and whether or not it carries external drop tanks full of fuel.

In military aviation, the combat radius of an aircraft is often given with its mission profile (without in-air refueling). For example:

The radius of action of an aircraft is always smaller than its maximum range, the furthest distance the aircraft can fly with maximum payload and without refueling, or ferry range, the furthest distance the aircraft can fly with drop tanks, no load or ordnance and without refueling. The rule of thumb is that the radius of action is one-third the distance an aircraft can fly in a straight line on a full load of fuel. In military aviation, this assumes a trip out and back, plus one-third of fuel for combat operations. [2]

<span class="mw-page-title-main">Lockheed P-38 Lightning</span> American twin-engined fighter of WWII

The Lockheed P-38 Lightning is an American single-seat, twin piston-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. Used in the aerial reconnaissance role, the P-38 accounted for 90 percent of American aerial film captured over Europe. 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-engine fighters.

Payload is the object or the entity which is being carried by an aircraft or launch vehicle. Sometimes payload also refers to the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight. Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally carried, is also considered part of the payload.

<span class="mw-page-title-main">Aerial refueling</span> Procedure in which flying aircraft receive fuel from another aircraft

Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft to another while both aircraft are in flight. The two main refueling systems are probe-and-drogue, which is simpler to adapt to existing aircraft, and the flying boom, which offers faster fuel transfer, but requires a dedicated boom operator station.

The Republic F-84 Thunderjet was an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter", the F-84 first flew in 1946. Although it entered service in 1947, the Thunderjet was plagued by so many structural and engine problems that a 1948 U.S. Air Force review declared it unable to execute any aspect of its intended mission and considered canceling the program. The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft.

Operations Black Buck 1 to Black Buck 7 were seven extremely long-range ground attack missions conducted during the 1982 Falklands War by Royal Air Force (RAF) Vulcan bombers of the RAF Waddington Wing, comprising aircraft from Nos. 44, 50 and 101 Squadrons, against Argentine positions in the Falkland Islands. Five of the missions completed attacks. The objective of the missions was to attack Port Stanley Airport and its associated defences. The raids, at almost 6,600 nautical miles and 16 hours for the round trip, were the longest-ranged bombing raids in history at that time.

The Boeing B-50 Superfortress is an American strategic bomber. A post–World War II revision of the Boeing B-29 Superfortress, it was fitted with more powerful Pratt & Whitney R-4360 radial engines, stronger structure, a taller tail fin, and other improvements. It was the last piston-engined bomber built by Boeing for the United States Air Force, and was further refined into Boeing's final such design, the prototype B-54. Although not as well known as its direct predecessor, the B-50 was in USAF service for nearly 20 years.

In aviation, a drop tank is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often capable of being jettisoned. External tanks are commonplace on modern military aircraft and occasionally found in civilian ones, although the latter are less likely to be discarded except in an emergency.

<span class="mw-page-title-main">Flight planning</span>

Flight planning is the process of producing a flight plan to describe a proposed aircraft flight. It involves two safety-critical aspects: fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air traffic control requirements, to minimise the risk of midair collision. In addition, flight planners normally wish to minimise flight cost through the appropriate choice of route, height, and speed, and by loading the minimum necessary fuel on board. Air Traffic Services (ATS) use the completed flight plan for separation of aircraft in air traffic management services, including tracking and finding lost aircraft, during search and rescue (SAR) missions.

Basic fighter maneuvers (BFM) are tactical movements performed by fighter aircraft during air combat maneuvering, to gain a positional advantage over the opponent. BFM combines the fundamentals of aerodynamic flight and the geometry of pursuit, with the physics of managing the aircraft's energy-to-mass ratio, called its specific energy.

<span class="mw-page-title-main">Range (aeronautics)</span> Distance an aircraft can fly between takeoff and landing

The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity considering both weight and volume limits. Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The fuel time limit for powered aircraft is fixed by the available fuel and rate of consumption.

<span class="mw-page-title-main">1945 Japan–Washington flight</span> Nonstop flight made by the USAAF after WW2

The 1945 Japan–Washington flight was a record-breaking air voyage made by three specially modified Boeing B-29 Superfortresses on September 18–19, 1945, from the northern Japanese island of Hokkaidō to Chicago in the Midwestern United States, continuing to Washington, D.C. The flight was made by three United States Army Air Forces (USAAF) generals and other airmen returning to the United States from their overseas duty after World War II. At that date, it involved the heaviest load carried by an American aircraft, the longest nonstop flight made by the USAAF, and the first nonstop flight from Japan to the United States made with a complete aircraft. However the flight did not break the then-world distance record established by the Royal Air Force in 1938. It's worth noting that the Martin PB2M was rated at 144,000 lb much earlier. Also, the tests of the B-29 under the leadership of E.H. Rowley in June, 1945 with Grand Slam bombs may have been run at similar loads.
