McDonnell Douglas Phantom FGR2

Two-seat air-defence interceptor · Phantom FGR2

Aircraft overview

The Phantom FGR2 is the RAF’s Spey-powered version of the American F-4. It is a two-seat, twin-engine combat aircraft that began in the ground-attack and tactical-reconnaissance roles before becoming an air-defence interceptor. Its combination of Sparrow or Skyflash missiles, Sidewinders and an external gun pod supported different kinds of engagement.

The British Phantom family includes the FG1, FGR2 and F-4J(UK). Their engines, equipment and service histories differ. The RAF’s last Phantom unit disbanded in September 1992, before Air Defender’s 1998 setting.

Role guidance · v0.8.16.0

Air Defender’s v0.8.16.0 catalogue includes Phantom FGR2 aircraft described as retained at Boscombe Down for weapons testing and contingency duties. This is a game premise: it does not mean an RAF Phantom squadron was standing air-defence duty in 1998.

The game’s catalogue values appear separately below. Compare the full aircraft designation in Aircraft Data, and use the specification guide when reading speed, height and range. A catalogue entry alone does not establish which aircraft are available in the current scenario.

In depth

A British version of the Phantom

Britain bought 118 Phantom FGR2s and 52 FG1s. Both British versions used Rolls-Royce Spey engines. The FG1 served as an interceptor with the Royal Navy and RAF; the FGR2 initially equipped RAF ground-attack and reconnaissance units in Germany.

The later F-4J(UK) acquisition was different. Fifteen former US Navy aircraft were refurbished and fitted with some British equipment after the 1982 South Atlantic deployment. They retained General Electric engines and were not converted into FGR2s.

Airframe, engines and flying weight

The FGR2 is approximately 17.55 m long, with an 11.7 m wingspan and a height of 4.9 m. Two low-bypass Spey turbofans provide propulsion. Reheat adds fuel to the hot exhaust behind the turbines for extra thrust, at a substantial increase in fuel use.

Its reference empty weight is about 14,061 kg and maximum take-off weight about 25,402 kg. The difference is shared by fuel, crew and stores; it is not an allowance available entirely for weapons. A heavy aircraft’s fuel state and load remain separate from the maximum figures in a specification table.

Crew and air-to-air weapons

A pilot and navigator operate the aircraft. Sparrow or Skyflash missiles occupy recesses beneath the fuselage, while Sidewinders are carried on wing pylons. An air-to-air fit comprises four Sparrow or Skyflash missiles and four Sidewinders. Skyflash uses radar guidance; Sidewinder homes on infrared energy.

The 20 mm M61 Vulcan cannon is carried in an external SUU-23 pod. The gun pod is a separate store, rather than an internal installation. Missile and gun provision therefore need to be considered as part of a particular aircraft’s load, not assumed from the Phantom name alone.

From attack to air defence

The FGR2’s early attack and reconnaissance service in Germany was followed by an interceptor career. From 1977 the RAF Phantom force concentrated on air defence. FGR2 interceptors served in both Britain and Germany.

Phantoms also deployed to the South Atlantic following the 1982 conflict. The end of the Cold War brought an accelerated reduction of the force, and its last RAF unit disbanded at the end of September 1992. This historical timeline is separate from the contingency aircraft included in Air Defender.

Variants

Phantom FG1

The Spey-powered interceptor version, also flown by the Royal Navy; 52 bought. Its figures are not the FGR2's.

Phantom FGR2

The RAF's ground-attack and tactical-reconnaissance version, 118 bought, used purely as an interceptor from 1977.

Phantom F-4J(UK)

Fifteen refurbished ex-US Navy F-4Js ordered after the 1982 Falklands deployment, with General Electric engines and some British equipment. A separate batch, not an FGR2.

Words used on this page

Choose an underlined term for a quick explanation, or browse the meanings here.

Interceptor

A fighter used to meet and investigate or, when authorised, engage another aircraft.

Related guide: qra launch
Turbofan

A gas-turbine engine that also drives a fan. Some fan air bypasses the engine core; that airflow and the core exhaust contribute thrust.

Related guide: aircraft engines
Feet / ft

A unit of length used here for aircraft height. Read the display’s scale: a trackblock height of 350 means 35,000 feet, not 350 feet.

Related guide: trackblock
Sortie

A mission flown by an aircraft, from take-off to landing. Air Defender also groups related aircraft under a sortie channel so you can follow their mission together.

Related guide: communications
Service ceiling

The stated height an aircraft can climb to while still meeting specified performance requirements. The game’s reference figure is not its current height or a guarantee for every situation.

How to read aircraft specifications
Contact

Something detected or being followed on the display. You may still need to establish what it is.

Related guide: plot or track
Knots

A unit of speed used in aviation: nautical miles per hour.

Related guide: trackblock
Cruise speed

A speed used for the main travelling part of a flight. A reference cruise speed is different from a track’s current speed.

Related guide: interceptor speed
Stall speed

A reference speed for the onset of a stall under specified conditions. A stall occurs when a wing or rotor blade exceeds its critical angle to the airflow and loses lift. It does not mean the engine has stopped.

How to read aircraft specifications
Range

Distance. For a contact it means distance from a stated point; an aircraft’s range means how far it can fly under stated conditions.

Related guide: range bearing
Nautical mile / NM

A distance unit used in aviation and navigation. It is different from the ordinary mile used on UK road signs.

Related guide: range bearing
Powerplant

The engine or engines that power the aircraft.

How to read aircraft specifications
Reheat / afterburner

An engine system that burns extra fuel in the exhaust behind the turbine for additional thrust. It uses much more fuel. Reheat and afterburner mean the same system.
