Everything about The Fairey Swordfish totally explained
The
Fairey Swordfish was a
torpedo bomber built by the
Fairey Aviation Company and used by the
Fleet Air Arm of the
Royal Navy during
World War II. Affectionately known as the
Stringbag by its crews, it was outdated by 1939, but achieved some spectacular successes during the war, notably the destruction of the
Regia Marina (the
Italian Navy) in the
Battle of Taranto and the famous crippling of the
Bismarck. It was operated primarily as a fleet attack aircraft, however, during its later years it was also used as an
anti-submarine and training craft. Designed in the 1930s, the Swordfish remained in frontline service through to the end of the war in Europe in 1945.
Design and development
The Swordfish was based on a Fairey
Private Venture (PV) design; a proposed solution to the
Air Ministry requirements for a Spotter-Reconnaissance plane - Spotter referring to observing the fall of a warship's gunfire. A subsequent
Air Ministry specification S.15/33, added the torpedo bomber role. The "Torpedo-Spotter-Reconnaissance" prototype
TSR II (the PV was the TSR I) first flew on
April 17,
1934. It was a large
biplane with a metal frame covered in fabric, and featured folding wings for
carrier use. An order was placed in 1935 and the aircraft entered service in
1936, replacing the
Fairey Seal in the torpedo bomber role.
By 1939 the Royal Navy had 13
squadrons equipped with the
Swordfish Mark I. There were also three flights of
Swordfish equipped with floats, for use off
catapult-equipped warships. One such, from
HMS Warspite spotted fall of shot (for example, radioed gunnery corrections back to the ship) during the
Second Battle of Narvik and subsequently sank the
U-boat U-64.
Swordfish flew from
merchant aircraft carriers ("MAC ships"), 20 civilian cargo ships modified to carry three or four aircraft each, on anti-submarine duties with convoys. Three of these ships were Dutch manned, flying
Swordfish from
860 (Dutch) Naval Air Squadron.
Almost 2,400 had been built, 692 by Fairey and 1,699 in
Sherburn by the
Blackburn Aircraft Company, which were sometimes dubbed the "Blackfish". The most numerous version was the Mark II, of which 1,080 were made.
Operational history
The primary weapon was the
torpedo, but the low speed of the biplane and the need for a long straight approach made it difficult to deliver against well-defended targets. However, Swordfish flying from
HMS Illustrious made a very significant strike, on
November 11,
1940, against the Italian navy during the
Battle of Taranto,
Italy, sinking or disabling three Italian battleships and a cruiser. The successful Taranto attack may have given inspiration or confidence to the Japanese who would later attack
Pearl Harbor. Swordfish also flew anti-shipping sorties from
Malta.
In May 1941 a Swordfish strike from
HMS Ark Royal was vital in damaging the German battleship
Bismarck, preventing it from escaping back to France. The low speed of the attacking aircraft may have acted in their favour, as the planes were too slow for the
fire-control predictors of the German gunners, whose shells exploded so far in front of the aircraft that the threat of
shrapnel damage was greatly diminished. The Swordfish also flew sufficiently low that most of the Bismarck's
flak was unable to hit them. The Swordfish aircraft scored two hits, one which did little damage but another which disabled the Bismarck's rudder, preventing it from maneuvering and thus sealing its fate. The Bismarck was destroyed less than 13 hours later.
The problems with the aircraft were starkly demonstrated in February 1942 when a strike on German
battlecruisers during the
Channel Dash resulted in the loss of all attacking aircraft. With the development of new torpedo attack aircraft, the Swordfish was soon redeployed successfully in an
anti-submarine role, armed with
depth-charges or eight "60 lb" (27 kg)
RP-3 rockets and flying from the smaller
escort carriers or even Merchant Aircraft Carriers when equipped for
rocket-assisted takeoff (RATO). Its low stall speed and inherently tough design made it ideal for operation from the MAC carriers in the often severe mid Atlantic weather. Swordfish-equipped units accounted for 14 U-boats destroyed. The Swordfish was meant to be replaced by the
Fairey Albacore, also a biplane, but actually outlived its intended successor. It was, however, succeeded by the
Fairey Barracuda monoplane torpedo bomber.
The last of 2,392 Swordfish aircraft was delivered in August 1944; the last operational squadron was disbanded on
21 May,
1945, after the fall of Germany; and the last training squadron was disbanded in the summer of 1946.
Origin of the Stringbag nickname
The Swordfish received the
Stringbag nickname not because of its construction but because of the seemingly endless variety of stores and equipment that the aircraft was cleared to carry. Crews likened the aircraft to a housewife's string
shopping bag which was common at the time and, which due to its having no fixed shape, could adjust to hold any shape or number of packages. Like the shopping bag, the crews thought the Swordfish could carry anything.
