English Electric Lightning — Fighter / Attack
Open in interactive gallery →

The English Electric Lightning (later British Aircraft Corporation Lightning after the BAC merger) is a British twin-engine, single-seat supersonic interceptor — with two-seat trainer variants — developed by English Electric and produced from 1957 to 1972. It entered Royal Air Force service in 1959 and remained the RAF's principal Cold War supersonic interceptor until retirement in 1988. Among post-war British fighters the Lightning stands out for its vertically-stacked twin-engine layout (unique among operational fighters), Mach 2 performance, and a climb rate that let it reach high-altitude Soviet bombers faster than most contemporary Western interceptors. It was the only entirely British supersonic fighter ever to enter RAF service. Production totalled 337 airframes; final RAF retirement came in 1988. Foreign operators were Saudi Arabia and Kuwait, both of which had retired the type by the late 1980s.

The Lightning is a swept-wing interceptor 55 ft (16.8 m) long with a 35 ft (10.6 m) wingspan. Empty weight is around 31,000 lb and maximum take-off weight 41,700 lb. Power comes from two Rolls-Royce Avon 301R afterburning turbojets rated at 13,200–16,300 lbf each depending on variant, mounted one above the other in the fuselage rather than side-by-side. Maximum speed is Mach 2.0+ (around 1,500 mph at altitude), with Mach 2.27 reached in test flights. Operational ceiling is 60,000+ ft, and from a supersonic dash the airframe could zoom-climb to 87,000 ft. Initial climb rate is roughly 50,000 ft/minute. Combat radius is short — about 150 nmi typical — because the Lightning was built for high-altitude rapid-response interception rather than extended sorties. Defining features include the stacked engine arrangement, integrated leading-edge intake, a ventral fuel tank, 2× ADEN 30mm cannons, and 2× de Havilland Firestreak or Red Top air-to-air missiles.

For Kids — a shorter, friendlier version

The English Electric Lightning was Britain's main supersonic high-altitude fighter in the 1960s and 70s. The Lightning is unique because it has two engines stacked vertically — one above the other, both at the back of the airplane. This unusual design made the Lightning narrower and faster than rivals.

The Lightning is about 55 feet long — longer than a school bus. Two Rolls-Royce Avon turbojets stacked top-and-bottom. Top speed Mach 2.27 (about 1,500 mph) — making the Lightning one of the fastest British fighters ever. The Lightning could climb to 50,000 feet in just 3 minutes — incredibly fast.

About 337 Lightnings were built between 1959 and 1968. Operators included Britain (RAF), Saudi Arabia, and Kuwait. The Lightning's main job was intercepting Soviet bombers attacking Britain — climbing fast and shooting down the bombers before they could attack.

The Lightning had short range (only 800 miles) — much less than rivals. It would burn fuel fast climbing to high altitudes. The RAF retired Lightnings in 1988, replaced by Tornado F.3s.

Saudi Arabia and Kuwait retired theirs by the early 1990s. About 6 Lightnings still fly today (in South Africa, Saudi Arabia, and the UK) at airshows.

Kids’ Questions

Why stack engines vertically?

English Electric designers wanted the Lightning to be narrow and aerodynamic. Putting two engines side-by-side (the usual approach) would make the airplane wider and slower. Stacking them top-and-bottom kept the airplane narrow. This worked great — the Lightning's narrow shape contributed to its high speed and climb rate. The downside: stacking engines is unusual and complex. Maintenance and access were difficult. No fighter since the Lightning has used vertically-stacked engines — every modern twin-engine fighter (F-15, F-22, Su-27, Tornado, Typhoon) has its engines side-by-side.

Why was the Lightning's short range a problem?

The Lightning could only fly 800 miles before running out of fuel — compared to 1,500+ miles for many other fighters of its era. Britain has a large coastline to defend; some areas were just outside Lightning's reach. The Lightning's short range came from its small fuel tanks (the narrow body and vertically-stacked engines left little room for fuel). The RAF eventually replaced Lightnings with the longer-range Tornado F.3 starting in 1986.

Variants

Frequently Asked Questions

Why did Lightning have stacked engines?

The arrangement was both an aerodynamic and a structural choice. Stacking two Avons on the fuselage centreline rather than placing them side-by-side or in the wings gave a smaller fuselage cross-section and lower wave drag at supersonic speed, kept thrust on the centreline so an engine failure produced no asymmetric yaw, and yielded a compact airframe that supported the Lightning's exceptional climb performance. No other operational fighter used the layout, although the Yak-141 and a handful of experimental designs explored related ideas. The stacked engines also gave the Lightning its instantly recognisable silhouette.

How fast did Lightning climb?

Initial climb rate was around 50,000 ft/minute, against 20,000–30,000 ft/min for typical contemporary fighters. The Lightning could climb from sea level to 36,000 ft in roughly 2 minutes 30 seconds, sustain Mach 2, and zoom-climb to 87,000 ft in test flights. That climb performance was central to the rapid-response interceptor mission — RAF Lightnings could reach Tu-95 'Bear' patrols approaching the UK Air Defence Region faster than most Western fighters of the era. Later types such as the F-15 and F-22 climb faster still, but for its day the Lightning was exceptional.

What weapons did Lightning carry?

The weapons fit was modest, reflecting the pure interceptor role. Armament comprised 2× ADEN 30mm cannons in the under-fuselage pack and 2× de Havilland Firestreak (F.1 / F.2) or Red Top (F.3 / F.6) air-to-air missiles, plus 4× microcell rocket pods that were rarely used operationally. Total ordnance was well below that of multirole types such as the F-4 Phantom II. The short combat radius and small weapons load were direct consequences of designing for short-range, high-altitude interception rather than extended-radius operations.

Why did Lightning retire in 1988?

Airframe life and the arrival of a successor. By the 1980s Lightning airframes were reaching their service-life limits, and the Panavia Tornado ADV (F.2 / F.3) had taken over the RAF interceptor role from 1986. The final Lightning retired in April 1988. That retirement also closed the chapter on all-British RAF fighters — every successor (Tornado, Eurofighter Typhoon) has been a multinational programme. The Lightning's 29-year service life reflects how long the RAF's high-altitude interceptor requirement persisted.

How does Lightning compare to F-104 Starfighter?

Both are 1950s–1960s Mach 2 interceptors. The F-104 Starfighter was a single-engine American design with 2,578 built and wide global export. The Lightning was a twin-engine British design with 337 built and limited export. The F-104 had a far larger production run and a more extensive combat record, while the Lightning offered British indigenous engineering and outstanding climb performance. The F-104 was controversial in service — Luftwaffe loss rates earned it the 'Widowmaker' nickname — whereas the Lightning had a comparatively better RAF safety record. Both remain iconic Mach 2 interceptors of the period.
