Fairey Swordfish
Fairey Aviation · Torpedo Bomber · UK · Interwar (1919–1938)
The Fairey Swordfish ('Stringbag') was a British single-engine biplane torpedo-bomber and reconnaissance aircraft built by the Fairey Aviation Company between 1934 and 1944. Entering Fleet Air Arm service in 1936, it gave the Royal Navy its principal carrier-borne anti-shipping, anti-submarine and reconnaissance capability throughout the Second World War, despite its obsolescent biplane layout. On 26 May 1941, Swordfish torpedoes crippled the rudder of the German battleship Bismarck, fixing her in place for surface units to sink the following day. Production reached 2,396 airframes, and the type remained in front-line Royal Navy service until 1945 — one of the most recognisable British aircraft of the war despite its archaic appearance.
Roughly 36 ft (11.0 m) long with a 46-ft (13.9 m) upper wingspan, the Swordfish had an empty weight near 5,200 lb and a maximum take-off weight of 9,250 lb. Power came from a single Bristol Pegasus IIIM3 / 30 radial of 690–750 hp, giving a top speed of 138 mph — well below contemporary monoplane fighters — a 16,500 ft service ceiling and a typical combat radius of 280 nmi with torpedo and external fuel. The biplane configuration delivered exceptional low-speed handling that suited short carrier flight decks. Armament was unusual for the size: an 18-inch 1,610-lb Mk XII torpedo carried single under the fuselage, or up to 1,500 lb of bombs, depth charges, mines or rockets, plus a rear-facing observer/gunner station with a .303 Vickers or Browning machine gun.
For Kids — a shorter, friendlier version
The Fairey Swordfish was a British torpedo bomber from World War II. Even by 1939 standards, it looked old-fashioned — a slow biplane with fabric-covered wings and an open cockpit. Pilots nicknamed it the "Stringbag" because the airplane carried so many different weapons and accessories (like an old lady's stringbag full of things).
The Swordfish is about 36 feet long — slightly bigger than a school bus. One Bristol Pegasus radial engine (690 hp). Top speed only 138 mph. Three crew members: pilot, observer, and gunner. The Swordfish carried one big torpedo, plus bombs, depth charges, or rockets.
The Swordfish achieved amazing things despite its slow speed. The most-famous: in November 1940, 21 Swordfish flew from HMS Illustrious to attack the Italian fleet at Taranto. They damaged three Italian battleships in the harbor — the first time a navy had been crippled by airplanes alone. This Taranto attack inspired Japan's Pearl Harbor attack a year later.
In May 1941, Swordfish from HMS Ark Royal attacked the German battleship Bismarck. A torpedo hit damaged the Bismarck's rudder, leaving it unable to steer. The Bismarck was sunk soon after.
About 2,400 Swordfish were built between 1936 and 1944. Some kept flying as anti-submarine aircraft until 1945. About 4 Swordfish still fly today at airshows.

Kids’ Questions
How did Swordfish survive in modern combat?
The Swordfish was slow (138 mph) — modern German fighters could fly twice that. But the Swordfish was actually safer than faster torpedo bombers in one specific way: its slow speed and low altitude meant German anti-aircraft guns had trouble aiming at it. Anti-aircraft predictors (computers that aimed the guns) were designed for fast aircraft and missed the slow Swordfish. Plus, the Swordfish flew low — under the radar in the days before low-altitude radar. The Swordfish couldn't survive against fighters in good weather, but in bad weather and at night, the Stringbag did its job and got home.
What was the Taranto attack?
On November 11, 1940, 21 British Swordfish from HMS Illustrious attacked the Italian fleet in the harbor at Taranto, Italy. The Swordfish came in at night, flying low and slow over the harbor, and dropped torpedoes. Three Italian battleships were damaged or sunk. This was the first time in history that an entire fleet was crippled by an air attack on a harbor. The Japanese studied the Taranto attack carefully — and used the same idea (with bigger forces) to attack Pearl Harbor on December 7, 1941. Taranto changed naval warfare forever.

Frequently Asked Questions
What is the Bismarck attack?
On 26 May 1941, 15 Swordfish from HMS Ark Royal launched a torpedo strike against the German battleship Bismarck during the Royal Navy Force H pursuit. Pressing through anti-aircraft fire, one or two torpedoes struck Bismarck's stern, wrecking the rudder and steering gear. Unable to steer, the battleship was forced to circle while pursuing British forces closed. The next morning, 27 May 1941, the battleships King George V and Rodney finished her off. Without the rudder hit, Bismarck would likely have reached a French port — making this strike one of the most decisive naval-aviation actions of WWII.
What was the Taranto raid?
On the night of 11–12 November 1940, 21 Swordfish from HMS Illustrious attacked the Italian battle fleet in harbour at Taranto. Their torpedoes struck three Italian battleships — Conte di Cavour, Caio Duilio and Littorio — sinking Conte di Cavour and damaging the others, for the loss of 2 Swordfish. Taranto was the first major carrier strike against capital ships in port and was studied closely by Imperial Japanese Navy planners preparing the December 1941 Pearl Harbor attack. The raid demonstrated that carrier torpedo aircraft could defeat heavy units in their own anchorage, reshaping naval-aviation doctrine.
Why was the Swordfish called 'Stringbag'?
Fleet Air Arm aircrew coined the nickname because the aircraft, like a string shopping bag, seemed able to carry whatever was thrown into it: torpedoes, bombs, depth charges, mines, rockets and ASV radar all from the same airframe. The generous wing area and straightforward biplane structure gave it remarkable payload flexibility for its size. The name reflects the affection Royal Navy crews had for a platform that remained combat-useful despite looking thoroughly obsolete, and British naval-aviation enthusiasts still use it today.
Why did the Swordfish stay operational so long?
Several reasons. The aircraft remained genuinely useful for anti-shipping torpedo work and ASW patrols flown from escort carriers. Its exceptional low-speed handling allowed it to operate from short escort-carrier decks where the Sea Hurricane, Wildcat and Avenger struggled. British production capacity for replacements was limited, so the Royal Navy kept Swordfish in production through 1944 to sustain fleet aviation. Its intended successors — the Fairey Albacore and Fairey Barracuda — suffered development problems, and the Swordfish actually outlasted the Albacore in production. Wartime utility and replacement-programme troubles together kept the Stringbag in service.
Where can I see a Swordfish today?
Around 7 Swordfish survive. The Royal Navy Historic Flight (RNHF) operates 2 airworthy examples — W5856 and LS326 — for display flights from the Fleet Air Arm Museum (RNAS Yeovilton, Somerset) and at airshows. Static examples are preserved at the Imperial War Museum Duxford, the RAF Museum Hendon, the Canadian Bushplane Heritage Centre and other collections. The type is well represented in British and Canadian naval-aviation museums and on the airshow circuit.
