The English Electric Lightning is a supersonic jet fighter aircraft of the Cold War era, noted for its great speed. It is the only all-British Mach 2 fighter aircraft and was the first aircraft in the world capable of supercruise. The Lightning was renowned for its capabilities as an interceptor; pilots commonly described it as "being saddled to a skyrocket". Following English Electric's integration into the unified British Aircraft Corporation, the aircraft was marketed as the BAC Lightning.
The Lightning was prominently used by the Royal Air Force and the Royal Saudi Air Force. The aircraft was a regular performer at airshows and is one of the highest-performance aeroplanes ever used in formation aerobatics. Following retirement in the late 1980s, many of the remaining aircraft became museum exhibits; until 2010, three examples were kept flying at "Thunder City" in Cape Town, South Africa. In September 2008, the Institution of Mechanical Engineers conferred on the Lightning its "Engineering Heritage Award" at a ceremony at BAE Systems' site at Warton Aerodrome.
The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 programme. It was soon realised that the aircraft should be regarded as a prototype fighter to satisfy the British Air Ministry's 1949 specification F23/49 rather than being a pure research aircraft. The Lightning design shared a number of innovations first planned for the Miles M.52 including the shock cone and all-moving tailplane or stabilator. The prototypes, known as P.1, were built to Ministry of Supply Operational Requirement ER.103 of 1947 for a transonic research aircraft. The first of the two P.1s WG760 flew for the first time from RAF Boscombe Down on 4 August 1954.
The P.1's chief designer was W.E.W "Teddy" Petter, formerly chief designer at Westland Aircraft. The design was controversial, and the Short SB5 was built to test wing sweep and tailplane combinations. The original combination was proved correct. The forerunner of the Lightning series was the P.1A and P.1B flying "proof-of-concept" aircraft. Looking very much like the production series, the prototypes were distinguished by the rounded-triangular intakes, short fins and lack of radar or operational equipment. Initial prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, although the Rolls-Royce Avon was used in subsequent aircraft. On 25 November 1958, the P.1B became the first British aircraft to fly at Mach 2. The second P.1A, WG763 was fitted with two 30mm ADEN cannons, however it was not possible to equip heavy underwing stores. Due to the limited internal space of the fuselage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance, additionally the tyres would rapidly wear out.
The first operational Lightning, designated the F.1, was designed as a point defence interceptor to defend mainland Britain from bomber attack. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range and combat endurance. It was equipped with two 30 mm ADEN cannon in front of the cockpit windscreen and an interchangeable fuselage weapon pack containing either an additional two ADEN cannon, 48, two inch air-to-air rockets, or two de Havilland Firestreak air-to-air missiles, a heavy fit optimized for attack of large aircraft. The Ferranti AI.23 radar (immediate predecessor of the AI.24 Foxhunter) supported autonomous search, automatic target tracking, and ranging for all weapons, while the pilot attack sight provided gyroscopically derived lead angle and backup stadiametric ranging for gun firing. The radar and gunsight were collectively designated the AIRPASS: Airborne Interception Radar and Pilot Attack Sight System.
The next two Lightning variants, the F.1A and F.2, saw steady but relatively minor refinement of the basic design, and the next variant, the F.3, was a major departure. The F.3 had higher thrust Avon 301R engines, a larger, squared-off fin and strengthened intake bullet allowing a service clearance to Mach 2.0 (the F.1, F.1A and F.2 were limited to Mach 1.7), the A.I.23B radar and Red Top missile offering a limited forward hemisphere attack capability—and most notoriously—deletion of the nose cannon. The new engines and fin made the F.3 the highest performance Lightning yet, but with an even higher fuel consumption and resulting shorter range. The next variant, the F.6, was already in development, but there was a need for an interim solution to partially address the F.3’s shortcomings. The F.3A was that interim solution.
The F.3A introduced two improvements: a new, non-jettisonable, 610 imperial gallons (2,800 l) ventral fuel tank, and a new, kinked, conically cambered wing leading edge, incorporating a slightly larger leading edge fuel tank, raising the total usable internal fuel to 716 imperial gallons (3,260 l). The conically cambered wing noticeably improved maneuverability, especially at higher altitudes, and the ventral tank nearly doubled available fuel. The increased fuel was very welcome, but the lack of cannon armament was felt to be a deficiency. It was thought that cannon were desirable to fire warning shots in the intercept mission.
The F.6 was the ultimate Lightning version to see British service. Originally, it was nearly identical to the F.3A with the exception that it had provisions to carry 260 imperial gallons (1,200 l) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency, and gave the F.6 a substantially improved deployment capability. There remained one glaring shortcoming: the lack of cannon. This was finally rectified in the form of a modified ventral tank with two ADEN cannon mounted in the front. The addition of the cannon and their ammunition decreased the tank's fuel capacity from 610 to 535 imperial gallons (2,770 to 2,430 l), but the cannon made the F.6 a “real fighter” again.
The final British Lightning was the F.2A. This was an F.2 upgraded with the cambered wing, the squared fin, and the 610 gal ventral. The F.2A retained the A.I.23 and Firestreak missile, the nose cannon, and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Lightnings, it had the longest tactical range of all Lightning variants, and was used for low-altitude interception over Germany.
Export and further developmentsEdit
The F.53 was the Export Lightning, adding a multirole capability to the interception-orientated design. The F.53 was based on the F.6 airframe and avionics, including the large ventral fuel tank, cambered wing and overwing pylons for drop tanks of the F.6, but incorporated an additional pair of hardpoints under the outer wing. These hardpoints could be fitted with pylons for air-to-ground ordnance, including two 1,000 lb (450 kg) bombs or four SNEB rocket pods each carrying 18 68 mm rockets. A gun pack carrying two ADEN cannon and 120 rounds each could replace the forward part of the ventral fuel tank.[nb 1] Alternative, interchangeable packs in the forward fuselage carried two Firestreak missiles, two Red Top missiles, twin retractable launchers for 44× 2-inch rockets, or a reconnaissance pod fitted with five 70 mm Type 360 Vinten cameras. BAC also proposed clearing the overwing hardpoints for carriage of weapons as well as drop tanks, with additional Matra JL-100 combined rocket and fuel pods (each containing 18 SNEB 68 mm (2.7 in) rockets and 227 litres (50 imp gal) of fuel) or 1,000 lb bombs being possible options. This could give a maximum ground attack weapons load for a developed export Lightning of six 1,000 lb bombs or 44 × 2-inch rockets and 144 × 68 mm rockets. The T.55 was the export two-seat variant; unlike the RAF two-seaters, the T.55 was equipped for combat duties. The T.55 had a very similar fuselage to the T.5, while also using the wing and large ventral tank of the F.6.
The Export Lightning had all of the capability of the British Lightnings: exceptional climb rate, agile manoeuvering, and a hard-hitting punch. Unfortunately, the Export Lightning also retained the difficulty of maintenance, and serviceability rates suffered. Still, the F.53 was generally well regarded by its pilots, and its adaptation to multiple roles showed the skill of its designers.
In 1963, BAC Warton worked on the preliminary design of a two-seat Lightning development with a variable-geometry wing, based on the Lightning T.5 with a revised undercarriage. Initially proposed as a carrier-based aircraft, the VG Lightning concept was revised into a land-based interceptor intended for the RAF the following year. However, no VG Lightning was ever built.
There were several unique and distinctive features in the design of the Lightning; principally the use of stacked and staggered engines, a notched delta wing, and a low-mounted tailplane. The vertically stacked, longitudinally staggered engines was the solution devised by Petter to the conflicting requirements of minimizing frontal area, providing undisturbed engine airflow across a wide speed range, and packaging two engines to provide sufficient thrust to meet performance goals. The configuration allowed the twin engines to be fed by a single nose inlet, with the flow split vertically aft of the cockpit, and the nozzles tightly stacked, effectively tucking one engine behind the cockpit. The result was a low frontal area, an efficient inlet, and excellent single-engine handling. Unfortunately, this stacked configuration led to complicated maintenance procedure, and the recurring problem of fluid leakage from the upper engine being a fire hazard.
The fuselage was tightly packed, leaving no room for fuel tankage or main landing gear. While the notched delta wing lacked the volume of a standard delta wing, each wing contained a fairly conventional three-section main fuel tank and leading-edge tank, holding 312 imp gal (1,420 l);[nb 2] the wing flap also contained a 33 imp gal (150 l) fuel tank and an additional 5 imp gal (23 l) was contained in a fuel recuperator, bringing the aircraft's total internal fuel capacity to 700 imp gal (3,200 l). The main landing gear was sandwiched outboard of the main tanks and aft of the leading edge tanks, with the flap fuel tanks behind. The long main gear legs retracted toward the wingtip, necessitating an exceptionally thin main tyre inflated to the high pressure of 330–350 psi (23–24 bar; 2,300–2,400 kPa).
A conformal ventral store was added to the design to house, alternatively, a fuel tank or a rocket engine. The rocket engine, a Napier Double Scorpion motor, also contained a reserve of 200 imp gal (910 l) of high-test peroxide (HTP) to drive the rocket’s turbopump and act as an oxidizer. Fuel for the rocket would have been drawn from the Lightning’s internal tankage. The rocket engine was intended to boost the Lightning’s performance against a supersonic, high altitude bomber threat, but this threat never emerged, thus the Lightning’s basic performance was deemed sufficient and the rocket engine option was cancelled in 1958. The ventral store saw wide use as an extra fuel tank, initially this was jettisonable and held 250 imperial gallons (1,100 l) of which 247 imp gal (1,120 l) were usable. Later ventral tanks were non-jettisonable.
Despite its acceleration, altitude and top speed, the Lightning found itself outclassed by newer fighters in terms of radar, avionics, weapons load, range, and air-to-air capability. More of a problem was the obsolete avionics and weapons fit. The radar had a short range and no track-while scan capability; it could only detect targets in a fairly narrow (40 degree) arc. While an automatic collision course attack system was developed and successfully demonstrated by English Electric, it was not adopted owing to cost concerns. Plans to supplement or replace the obsolete Red Top and Firestreak missiles with modern AIM-9L Sidewinder missiles never came to fruition because of lack of funding,
Early models of the Lightning the F.1, F.1A, and F.2, had a rated top speed of Mach 1.7 at 36,000 feet (11,000 m) in an ICAO standard atmosphere, and 650 knots (750 mph; 1,200 km/h) Indicated airspeed (KIAS) at lower altitudes. Later models, the F.2A, F.3, F.3A, F.6, and F.53, had a rated top speed of Mach 2.0 at 36,000 feet (11,000 m), and speeds up to 700 knots (810 mph; 1,300 km/h) indicated air speed for “operational necessity only.” A Lightning fitted with Avon 200-series engines, a ventral tank and two Firestreak missiles typically ran out of excess thrust at Mach 1.9 on a Standard Day; while a Lightning powered by the Avon 300-series engines, a ventral tank and two Red Top missiles ran out of excess thrust at Mach 2.0. As speed increased, the Lightning's directional stability decreased; there were potentially hazardous consequences in the form of vertical fin failure if yaw was not rapidly counteracted by correct rudder use.[nb 3] Stability was protected by imposed Mach limits during missile launches;[nb 4] later Lightning variants featured a larger vertical fin which gave a greater stability margin during high speed flight.
Supersonic speeds also threatened inlet stability; the inlet's central shock cone served as a compression surface, diverting air into the annular inlet. As the Lightning accelerated through Mach 1, the shock cone generated an oblique shock positioned forward of the intake lip; known as a subcritical inlet condition, this is stable but also produces inefficient spillage drag. Around the Design Mach speed, the oblique shock is positioned just in front of the inlet lip and efficiently compressed the air without any spillage. As speed increases beyond Design Mach, the oblique shock becomes supercritical, where supersonic airflow enters the inlet duct. The inlet could only handle subsonic air, a supercritical state drastically reduced thrust output but could also lead to surges or compressor stalls, which may cause flameouts or engine damage.
Thermal and structural limits were also present; as air is heated up when compressed by the passage of an aircraft. This heating increases considerably when at supersonic speeds. The airframe absorbs heat from the surrounding air, the inlet shock cone at the front of the aircraft becoming the hottest part. The shock cone was composed of fibreglass, necessary because the shock cone also served as a radar radome; a metal shock cone would interfere with the AI 23’s radar emissions. The shock cone would be eventually weakened due to the fatigue caused by the thermal cycles involved in regularly performing high-speed flights. At 36,000 feet (11,000 m) and Mach 1.7, the heating conditions on the shock cone would be similar to those at Sea Level and 650 knots (750 mph; 1,200 km/h) indicated airspeed,[nb 5] but if the speed was increased to Mach 2.0 at 36,000 feet (11,000 m), the shock cone would be exposed to higher temperatures[nb 6] than those at Mach 1.7. The shock cone was strengthened on the later Lightning F.2A, F.3, F.6, and F.53 models, thus allowing routine operations at up to Mach 2.0.
The small-fin variants could exceed Mach 1.7,[nb 7] but the stability limits and shock cone thermal/strength limits made such speeds risky. The large-fin variants, especially those equipped with Avon 300-series engines could safely reach Mach 2, and given the right atmospheric conditions, might even achieve a few more tenths of a Mach. All Lightning variants had the excess thrust to slightly exceed 700 knots (810 mph; 1,300 km/h) indicated airspeed under certain conditions, and the service limit of 650 knots (750 mph; 1,200 km/h) was occasionally ignored. With the strengthened shock cone, the Lightning could safely approach its thrust limit, but fuel consumption at very high airspeeds was excessive and became a major limiting factor.[nb 8]
The Lightning possessed a remarkable climb rate. It was famous for its ability to rapidly rotate from takeoff to climb almost vertically from the runway, though this did not yield the best time to altitude. The Lightning's trademark tail-stand manoeuvre exchanged airspeed for altitude; it could slow to near-stall speeds before commencing level flight. The Lightning’s optimum climb profile required the use of afterburners during takeoff. Immediately after takeoff, the nose would be lowered for rapid acceleration to 430 KIAS before initiating a climb, stabilising at 450 KIAS. This would yield a constant climb rate of approximately 20,000 ft/min.[nb 9] Around 13,000 ft the Lightning would reach Mach 0.87 and maintain this speed until reaching the tropopause, 36,000 ft. on a standard day.[nb 10] If climbing further, pilots would accelerate to supersonic speed at the tropopause before resuming the climb.
A Lightning flying at optimum climb profile would reach 36,000 ft in under three minutes. The official ceiling was kept as a secret, although low security RAF documents usually stated 60,000+ ft (18 000+ m). In September 1962 Fighter Command organised several supersonic interception trials on Lockheed U-2As at heights of around 60,000-65,000 ft, which were temporarily based at RAF Upper Heyford to monitor Soviet nuclear tests. For the trials operations were carried out by the AFDS temporarily moved to RAF Middleton St George. Energy climb techniques and flight profiles were developed to put the Lightning into a suitable attack position. To avoid risking the U-2, the Lightning could not be permitted to close any closer than 5,000 ft and definitely could not be allowed to fly in front of the U-2. For the actual intercepts, four Lightning F1As were used on eighteen solo sorties. The sorties proved that, under GCI, successful intercepts could be made at up to 65,000 ft. Carried out against the backdrop of the Cuban missile crisis, the flight targets were deliberately not listed in the pilot log books. RAF Lightning pilot and Chief Examiner Brian Carroll reported taking a Lightning F.53 up to 87,300 feet (26 600 m) over Saudi Arabia at which level "Earth curvature was visible and the sky was quite dark", noting that control-wise "[it was] on a knife edge".
In 1984, during a major NATO exercise, Flt Lt Mike Hale intercepted a U-2 at a height which they had previously considered safe from interception (thought to be 66,000 feet). Records show that Hale also climbed to 88,000 ft (26,800 m) in his Lightning F.3 XR749. This was not sustained level flight, but in a ballistic climb or a zoom climb, in which the pilot takes the aircraft to top speed and then puts the aircraft into a climb, trading speed for altitude. Hale also participated in time-to-height and acceleration trials against Lockheed F-104 Starfighters from Aalborg. He reports that the Lightnings won all races easily with the exception of the low-level supersonic acceleration, which was a "dead heat".
Carroll compared the Lightning and the F-15C Eagle, having flown both aircraft, stating that: "Acceleration in both was impressive, you have all seen the Lightning leap away once brakes are released, the Eagle was almost as good, and climb speed was rapidly achieved. Takeoff roll is between 2,000 and 3,000 ft [600 to 900 m], depending upon military or maximum afterburner-powered takeoff. The Lightning was quicker off the ground, reaching 50 ft [15 m] height in a horizontal distance of 1,630 feet [500m]". Chief Test Pilot for the Lightning Roland Beamont, who also flew most of the "Century series" US aircraft, stated his opinion that nothing at that time had the inherent stability, control and docile handling characteristics of the Lightning throughout the full flight envelope. The turn performance and buffet boundaries of the Lightning were well in advance of anything known to him.
Royal Air ForceEdit
The first aircraft to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Lightning for entry into service. The production Lightning F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Lightning F.1 entered front-line squadron service with 74 Squadron at Coltishall from 11 July 1960. While performance was excellent, with the aircraft's radar and missiles effective and pilots finding the Lightning easy to fly, serviceability was at first extremely poor. This was due to both the complexity of Lightning's systems and shortages of spares and ground support equipment. Even when the Lightning was not grounded by technical faults, the RAF struggled to get more than 20 flying hours per aircraft per month compared with the 40 hours that English Electric believed could be achieved with proper support.
Despite these problems, in addition to its training and operational roles, 74 Squadron was appointed as the official Fighter Command aerobatic team for 1961, flying at air shows throughout the United Kingdom and Europe. Deliveries of the slightly improved Lightning F.1A, with improved avionics and provision for an air-to-air refuelling probe, allowed two more squadrons, 54 and 111 Squadron, both based at RAF Wattisham to convert to the Lightning in 1960–1961.
An improved variant, the F.2 first flew on 11 July 1961 and entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the use of the two seat T.4 trainer, which entered service with the Lightning Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two seater, small numbers were also allocated to the front-line fighter squadrons. The "next generation" Lightning F.3, with more powerful engines and the ability to use the new Red-Top missile (although at the cost of losing the little-used cannon) was expected to be the definitive Lightning, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. The F.3 was first flown on 16 June 1962 and the longer-range F.6 on 16 June 1965.
The English Electric Lightning is credited with a single kill, a British Harrier pilot ejected and the pilot-less aircraft continued to fly, and the aircraft was shot down by a Lightning to prevent it possibly ending up in Soviet hands.
In British Airways trials in April 1985, Concorde was offered as a target to NATO fighters including F-15 Eagles, F-16 Fighting Falcons, F-14 Tomcats, Mirages, and F-104 Starfighters - but only Lightning XR749, flown by Mike Hale and described by him as "a very hot ship, even for a Lightning", managed to overtake Concorde on a stern conversion intercept.
During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Lightning's range and firepower shortcomings became increasingly apparent. The withdrawal of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force alongside those withdrawn from Germany which were being replaced by SEPECAT Jaguars in the ground attack role.
The Lightning's direct replacement was the Tornado F3s, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Lightning, including a far larger weapons loadout and considerably more advanced avionics. Lightnings were slowly phased out of service between 1974 and 1988. In their final years the airframes required considerable maintenance to keep them in airworthy condition due to the sheer number of accumulated flight hours.
- Fighter Command/Strike Command
- The main Lightning role was the air defence of the United Kingdom and was operated at first as part of Fighter Command and then from 1968 with No. 11 Group of Strike Command. At the formation of Strike Command nine Lightning squadrons were operational in the United Kingdom.
- Far East Air Force
- In 1967 No. 74 Squadron was moved to RAF Tengah, Singapore to take over the air defence role from the Gloster Javelin equipped 60 Squadron. The squadron was disbanded in 1971 following the withdrawal of British forces from Singapore.
- Near East Air Force
- The Royal Air Force had detached Lightnings to RAF Akrotiri, Cyprus to support the Near East Air Force and in 1968 No. 56 Squadron RAF moved from RAF Wattisham with the Lightning F.3 to provide a permanent air defence force, it converted to the F.6 in 1971 and returned to the United Kingdom in 1977.
- Royal Air Force Germany
- In the early 1960s No. 19 Squadron and No. 92 Squadron with Lightning F.2s, moved from RAF Leconfield to RAF Gütersloh in West Germany as part of Royal Air Force Germany and operated in the low-level air defence role until disbanded in 1977 when the role was taken over by the Phantom FGR2.
On 21 December 1965, Saudi Arabia, keen to improve its air defences owing to the Saudi involvement in the North Yemen Civil War and the resultant air incursions into Saudi airspace by Egyptian forces supporting the Yemeni Republicans, placed a series of orders with Britain and the United States to build a new integrated air defence system. BAC received orders for 34 multirole single-seat Lightning F.53s that could still retain very high performance and reasonable endurance, and six two-seat T.55 trainers, together with 25 BAC Strikemaster trainers, while the contract also included new radar systems, American HAWK surface to air missiles and training and support services.
In order to provide an urgent counter to the air incursions, with Saudi towns close to the border being bombed by Egyptian aircraft, an additional interim contract, called "Magic Carpet", was placed in March 1966 for the supply of six ex-RAF Lightnings (four F.2s and two T.4 trainers, redesignated F.52 and T.54 respectively[nb 11]), six Hawker Hunters, two air defence radars and a number of Thunderbird surface-to-air missiles. The "Magic Carpet" Lightnings were delivered to Saudi Arabia in July 1966, with an additional F.52 being delivered in May 1967 to replace a Lightning lost in an accident. The Lightnings and Hunters, flown by contract pilots, were deployed to Khamis Mushait airfield near the Yemeni border, resulting in the curtailing of operations by the Egyptian Air Force over the Yemeni-Saudi border. Although the first F.53s had been handed over to the RSAF in December 1967, they were kept at Warton while trials and development continued and the first Saudi Lightnings to leave Warton were four T.55s delivered in early 1968 to the Royal Air Force 226 Operational Conversion Unit at RAF Coltishall, the four T.55s were used to train Saudi aircrew for the next 18 months. The new-build Lightnings were delivered under Operation "Magic Palm" between July 1968 and August 1969. Two Lightnings, a F.53 and a T.55 were destroyed in accidents prior to delivery, and were replaced by two additional aircraft, the last of which was delivered in June 1972.
The multirole F.53s served in the ground attack and reconnaissance roles as well as an air defence fighter, with Lightnings of No 6 Squadron RSAF carrying out ground attack missions using rocket and bombs during a border dispute with South Yemen between December 1969 and May 1970. One F.53 (53-697) was shot down by Yemeni ground fire on 3 May 1970 during a reconnaissance mission, with the pilot ejecting successfully and being rescued by Saudi forces. Saudi Arabia received Northrop F-5E fighters from 1971, which resulted in the Lightnings relinquishing the ground-attack mission, concentrating on air defence, and to a lesser extent, reconnaissance. Up to 1982 the Lightnings were mainly operated by 2 and 6 Squadron RSAF (although a few were also used by 13 Squadron RSAF), but when 6 Squadron re-equipped with the F-15 Eagle then all the remaining aircraft were operated by 2 Squadron at Tabuk. In 1985 as part of the agreement to sell the Panavia Tornado to the RSAF, the 22 flyable Lightnings were traded in to British Aerospace and returned to Warton in January 1986. While BAe offered the ex-Saudi Lightnings to Austria and Nigeria, no sales were made, and the aircraft were eventually disposed of to museums.
Kuwait also ordered 14 Lightnings in December 1966, comprising 12 F.53Ks and two T.55Ks. The first Kuwait aircraft, a T.55K first flew on 24 May 1968 and deliveries to Kuwait started in December 1968. The Kuwaitis somewhat overestimated their ability to maintain such a complex aircraft, not adopting the extensive support from BAC and Airwork Services that the Saudis used to keep their Lightnings operational, so serviceability was poor. The Kuwaiti Lightnings did not have a long service career; after unsuccessfully trying to sell them to Egypt in 1973, Kuwait replaced its last Lightnings by Dassault Mirage F1s in 1977.

- British journalist and TV presenter Jeremy Clarkson borrowed a Lightning (serial XM172) which was temporarily placed in his garden and documented on Clarkson's TV show Speed.
- Professor Brian Cox uses one of the South African Lightnings (XS451) in his "Wonders of the Solar System" BBC TV programme - episode 3 of 5, "The Thin Blue Line". The broadcast features a "vertical" ascent, and allows the Professor to show the curvature of the Earth and the relative dimensions of the atmosphere. More than five minutes of the episode are devoted to the Lightning, with a large number of close-ups. Coincidentally, this was the aircraft that crashed only about a month later at the Overberg Airshow, after developing mechanical problems.
- British author Jan Mark's children's book Thunder and Lightnings (1976) tells the story of two boys living near RAF Coltishall in Norfolk, who share an interest in aeroplanes, at the time when the RAF is phasing out its Lightning fighters and introducing the Jaguar.
- An old, destroyed Lightning, now used for target practice on a Northumberland military range, is featured on the cover of the Suede album Sci-Fi Lullabies.
- Five ex-Saudi F.53s (ZF577, ZF585, ZF586, ZF589 and ZF590) were used in the filming of the movie Wing Commander as the cockpit and main fuselages of the "star" fighters, the CF-117b Rapier. The forward fuselages were put into storage, presumably for later reuse in possible sequels, but the movie flopped, two of the nose sections were scrapped (ZF585 and ZF589). ZF577 and ZF586 were put into storage. The fifth, ZF590, was rescued from the scrap heap by a private enthusiast.
- A haunted Lightning, previously attached to a fictional 666 Squadron and officially listed as destroyed, is kept at the aircraft museum at RAF Cosford in the Charles Stross novel The Fuller Memorandum.

- List of aircraft of the RAF
- List of fighter aircraft
- List of accident and incidents involving the English Electric Lightning
- ↑ The ventral cannon installation was designed for the export aircraft but was later adopted by the RAF for the F.6 and F.2A.
- ↑ All fuel tank volumes are listed in Imperial gallons
- ↑ Along with directional stability, rudder effectiveness decreased at higher Mach numbers; timely and larger deflections of the rudder were required to counter any yaw, especially under increased g-loading. Two Lightning prototypes, XL628 and XM966, were lost to vertical fin failure during roll testing at high Mach numbers.
- ↑ Firestreak firing limits were Mach 1.3 with the small fin, Mach 1.7 with the large fin. Red Top limit was Mach 1.8.
- ↑ On a standard day, the temperature of the air at the tip of the shock cone (stagnation temperature) was 156 °F (69 °C) at Mach 1.7 and 36,000 feet (11,000 m). At Sea Level and 650 knots (750 mph; 1,200 km/h) indicated airspeed, this temperature was 151 °F (66 °C).
- ↑ At Mach 2.0, the stagnation temperature would be 242 °F (117 °C).
- ↑ Roland Beamont took the Lightning P.1B XA847, a prototype of the F.1, to Mach 2.0. Prior testing had determined that the aircraft would have the excess thrust to achieve this speed given the right atmospheric conditions of a high tropopause and lower than standard temperature. The test flight was to check for inlet stability and monitor temperatures at higher Mach. The aircraft was equipped with a temperature probe to monitor the stagnation temperature, up to a never-exceed temperature of 115 °C. On 28 November 1958, the weather availed a high tropopause and a substandard -67 °C at 40,000 feet (12,000 m). This was sufficient to allow Beamont to achieve Mach 2.0 in a British aircraft for the first time, reached only 7 minutes after takeoff, the record dash left the Lightning critically short of fuel. The Machmeter fitted to service Lightning F.1s and F.1Bs had a scale that stopped at Mach 1.8—with a redline at 1.7.
- ↑ At 30,000 feet (9,100 m), a Lightning F.6 would require approximately 1 minute and 1,250 pounds (570 kg) of fuel to accelerate from 650 to 675 knots (748 to 777 mph; 1,204 to 1,250 km/h) indicated airspeed.
- ↑ The Lightning would increase forward velocity during the climb, the angle of the climb lessening from about 27 deg to 19 deg at 13,000 ft.
- ↑ The true airspeed associated with a given indicated airspeed increases with altitude. Below the tropopause, the true airspeed associated with a given Mach number decreases with altitude. The Lightning’s Air Data System automatically corrected for errors in position and speed; following correction, 450 KIAS was equal to Mach 0.87 at 13,000 ft.
- ↑ A single F.1 was supplied as a ground instructional airframe.
- ↑ The value for "empty weight" is really the Zero Fuel weight, which includes equipped pilot, Red Top missiles, cannon and ammunition. The Basic weight, without these items, is 27,759 lb.
- ↑ The maximum permissible weight for takeoff and all forms of flying is 45,750 lb. At weights above 45,000 lb, the mainwheel tyres have to be changed after one use.
- ↑ An F.6 equipped with Red Top missiles can reach Mach 2.0 on an ICAO Std. day at 36,000 ft. A clean F.6 can reach Mach 2.1 at 37,000 ft .
- ↑ This is based on a maximum-range subsonic intercept radius of 370 NM (425 mi, 625 km). An F.6 equipped with Red Top missiles can climb to 36,000 ft and cruise at Mach 0.87 to a loiter or intercept area 370 NM distant. It then has 15 minutes on station to complete the intercept or identification task before returning to base. The afterburners are not used during this profile, and the total mission time is 112 min.
- ↑ An F.6 equipped with Red Top missiles can climb to 36,000 ft, accelerate to Mach 1.8, and intercept a target at 135 NM only 10.7 min after brake release. A 2g level turn allows a rear-quarter re-attack 1.6 min later. Following a best-range cruise and descent, the Lightning enters the landing pattern with 800 lb of fuel remaining with a total mission time of 35 min.
- ↑ This is the initial climb rate associated with the Lightning’s best time-to-climb profile of 450 KIAS to Mach 0.87. Using this profile, a Lightning F.6 with Red Top missiles can climb from Sea Level to 36,000 ft in 2.1 min following initial acceleration to 450 KIAS, or 2.8 min from brake release. A clean F.6 can perform the same climb in 2.0 min following initial acceleration, or 2.7 min from brake release.
- ↑ Wing loading is calculated from the above weight and wing area data. The listed value represents an F.6 with Red Top missiles and 1/2 fuel. The wing loading can range between 86-67 lb/ft² over the duration of a mission, depending on fuel load.
