English Electric Canberra
The bomber that refused to retire
Britain’s first jet bomber — a simple, broad-winged machine built to fly higher than any fighter could reach. It set world altitude records, was licence-built in America as the Martin B-57, and in NASA’s hands is still flying today, more than 75 years after its first flight.
Simple, high, and impossible to kill off
In 1944 the Air Ministry wanted a jet successor to the wooden de Havilland Mosquito — a fast, unarmed bomber that would survive by flying too high and too fast to be caught. The job went to a young English Electric team led by W. E. W. “Teddy” Petter, and the aircraft that emerged, first flown on 13 May 1949, was almost shocking in its simplicity: a broad, low-loaded straight wing, a fat fuselage, and two Rolls-Royce Avon turbojets. No swept wing, no gun turrets, no complexity for its own sake.
That plain recipe worked brilliantly. The Canberra could cruise above 48,000 ft — higher than the fighters sent to intercept it — and it climbed and turned better up there than almost anything of its era. It entered RAF service in 1951 as Britain’s first jet bomber, set a string of world altitude records through the 1950s, and became one of the great export successes in British aviation history: licence-built in the United States as the Martin B-57 and in Australia, and flown by well over a dozen air forces.
Its real trick, though, was longevity. The airframe was so adaptable — bomber, photo-reconnaissance, interdictor, trainer, target-tug, high-altitude testbed — that operators simply refused to give it up. The RAF flew its last Canberras in 2006; India retired hers in 2007. And NASA’s WB-57s are still flying scientific missions in the 2020s, making the Canberra one of the longest-serving jet designs ever built.
01Why the Canberra could fly higher than the fighters chasing it
The Canberra’s secret was its wing. Petter’s team gave it an unusually large, thick, low-aspect straight wing — a big lifting surface carrying a relatively light aircraft. That low wing-loading meant the Canberra kept generating lift in the thin air of the high stratosphere, where sharper-winged jet fighters ran out of performance and mushed into a stall. Combined with two efficient Avon engines, it could operate above 48,000 ft and, in specialised forms, far higher.
For most of the early 1950s that put it out of practical reach: interceptors that could match its altitude couldn’t manoeuvre once they got there. The trade-off was speed — the straight wing capped the Canberra at around Mach 0.88, firmly subsonic — but for a bomber meant to slip over a target and leave, altitude mattered more than raw speed. It is the same logic that later produced the Canberra-derived, and even higher-flying, reconnaissance aircraft.
What makes the Canberra special
A big straight wing built for the stratosphere
The Canberra’s defining feature is its broad, low-loaded straight wing paired with two Rolls-Royce Avon turbojets. Where fighters used thin swept wings for speed, the Canberra used a large wing area to keep flying in thin air — giving it a service ceiling around 48,000 ft and, in record-setting forms with uprated engines, well over 60,000 ft. For years it simply flew above the threat.
One airframe, endless jobs
Unarmed and aerodynamically honest, the Canberra proved extraordinarily adaptable. It served as a level bomber, low-level interdictor, photo-reconnaissance platform with up to seven cameras, dual-control trainer, target-tug, radar calibrator and high-altitude testbed. Some 27 variants were built, which is a large part of why so many air forces bought it and kept it.
Longevity — and a second life in research
The Canberra’s clean high-altitude airframe made it perfect for science. NASA operates a small fleet of WB-57 high-altitude research aircraft — direct descendants of the Martin-built Canberra — still flying atmospheric sampling, sensor testing and spacecraft re-entry tracking in the 2020s, more than seven decades after the type first flew.
02The Canberra and the Martin B-57: an American Canberra
When the US Air Force needed a fast tactical bomber in the early 1950s and its own designs disappointed, it did something almost unheard of: it licensed a British aircraft. The Glenn L. Martin Company built the Canberra as the B-57, and though early examples were near-identical, later versions diverged sharply — a redesigned cockpit, rotary bomb door, and eventually the enormous long-span RB-57F/WB-57 high-altitude variants. Around 403 B-57s were built in the United States. They fought over Vietnam, and it is the WB-57 line that keeps the Canberra family airborne with NASA today.
03Record after record: how the Canberra kept climbing
Through the 1950s the Canberra rewrote the altitude tables. On 4 May 1953 a Canberra fitted with Bristol Olympus engines reached about 63,668 ft; on 29 August 1955 another set a record near 65,889 ft. The peak came on 28 August 1957, when a Canberra using a Napier Double Scorpion rocket motor in addition to its jets zoom-climbed to 70,310 ft (21,430 m) — a world altitude record at the time. These flights showed just how much altitude the basic airframe had in reserve.

04What did a Canberra cost — and why the numbers are fuzzy
The Canberra was a 1950s state-era product sold across many countries in wildly different deals, so no single trustworthy flyaway price exists in open sources, and cost-per-flight-hour figures for the type are not reliably published either. What is well documented is the production spread: roughly 900 built in Britain, about 403 as the Martin B-57 in the United States, and 48 licence-built in Australia — on the order of 1,350 aircraft in total. Any precise dollar figure attached to a Canberra should be treated as an estimate.

Where the Canberra flew
A bomber that fought on every side of the Cold War
The Canberra almost never fought as a dogfighter — it had no guns for that. Its combat record is written in bombs dropped and photographs taken, over Malaya and Suez, Vietnam, the India–Pakistan wars and the Falklands. It was also, grimly, the first aircraft in history shot down by a guided missile. Figures below are best-available estimates and are contested in places.
