Cordite is a family of
smokeless propellants developed and produced in the United Kingdom since
1889 to
replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a
low explosive because of its
slow burning rates and consequently
low brisance. These produce a
subsonic deflagration wave rather than the supersonic
detonation wave produced by brisants, or
high explosives. The hot gases produced by burning gunpowder or cordite generate
sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the
barrel of the
gun.
Cordite was used initially in the
.303 British, Mark I and II, standard rifle cartridge between
1891 and 1915; shortages of cordite in
WW1 led to United States–developed smokeless powders being imported into the UK for use in rifle cartridges. Cordite was also used for large weapons, such as
tank guns, artillery, and naval guns. It has been used mainly for this purpose since the
late 19th century by the UK and
British Commonwealth countries. Its use was further developed before
WW2, and as 2-and-3-inch-diameter (51 and 76 mm)
Unrotated Projectiles for launching
anti-aircraft weapons. Small cordite rocket charges were also developed for
ejector seats made by the
Martin-Baker Company. Cordite was also used in the detonation system of the
Little Boy atomic bomb
dropped over Hiroshima in August 1945.
The term "cordite" generally disappeared from official publications between the wars. During WW2,
double based propellants were very widely used, and there was some use of triple based propellants by artillery. Triple based propellants were used in post-war ammunition designs and remain in production for UK weapons; most double based propellants left service as World War II stocks were expended after the war. For small arms it has been replaced by other propellants, such as the
Improved Military Rifle (IMR) line of extruded powder or the WC844
ball propellant currently in use in the
5.56×45mm NATO.
[2] Production ceased in the United Kingdom around the end of the 20th century, with the closure of the last of the World War II cordite factories,
ROF Bishopton. Triple base propellant for UK service (for example, the
105 mm L118 Light Gun) is now manufactured in Germany.
