The EM-2, also known as Rifle, No.9, Mk.1 or Janson rifle, was a British assault rifle. It was briefly adopted by British forces in 1951, but the decision was overturned very shortly thereafter by Winston Churchill's incoming government in an effort to secure NATO standardisation of small arms and ammunition. It was an innovative weapon with the compact bullpup layout, built-in carrying handle and an optical sight.
The gun was designed to fire one of the first purpose-designed entirely new intermediate cartridges, designed to a 1945 requirement as a result of combat experience and German advances in weapons design during World War II. The round, the .280 British, was designed to replace the .303 round, which dated to the late 19th century. The EM-2 was intended to replace the Lee-Enfield bolt-action rifles and various submachineguns, while the TADEN would replace the Bren gun and Vickers machine gun.
As part of NATO standardization efforts, the United States claimed the .280 British round was too weak for use in rifles and machine guns, and instead favoured the much more powerful 7.62×51mm NATO round. A bullpup layout for a British service rifle was finally adopted some years later in form of the SA80 assault rifle, which remains in service today.
The British Army entered World War II with infantry weapons based on the .303 British round, including the Lee-Enfield bolt-action rifle, Vickers machine gun and the Bren gun. The .303 had been developed near the end of the 19th century, and had several problems when used in modern designs, notably, the rimmed cartridge design that made it more difficult to use in a magazine. Although the Army had intended to replace the .303 on several occasions dating from before World War I, these efforts were repeatedly put off due to one crisis after another. There had been some consideration of a less powerful cartridge just prior to the start of WWII, using a 7.92 mm bullet, but in the aftermath of the Dunkirk evacuation, any interest in this development ended.
In the immediate post-war period, Royal Small Arms Factory, Enfield began the development of a series of designs firing German rounds. Polish designer Roman Korsak was producing a new light machine gun firing the 7.92×57mm Mauser round using a mechanism similar to the FG 42 known as the EM-1, while Jeziorański was designing an infantry weapon firing the StG 44's 7.92×33mm Kurz, the EM-2. A second infantry weapon was developed by Metcalf, the EM-3, but was not successful.
As the war ran down, in 1945 the Army formed the Small Arms Calibre Panel (SACP) to develop a new standard calibre for future weapons. Military intelligence suggested that it would be ten years before the Soviets would be ready for another major war, so the time frame for re-equipping was the mid-to-late 1950s. This gave the Panel ample time to test a number of options.
Experience during the war led to demands for a smaller "intermediate" sized cartridge that would allow fully automatic fire from a rifle-sized weapon. The Army demanded a high degree of accuracy due to the emphasis on marksmanship, so the new round was designed to meet the performance of the .303 (7.7 mm) at 1,000 yards (910 m) but at the reduced range of 600 yards (550 m). After testing a variety of designs, they selected a bullet of about .270 in (6.9 mm) calibre and 1 inch (2.5 cm) long, with a mass of 130 grains (8.4 g). [3]
With the release of the SACP reports, interest in the original series of EM weapons ended and a call for weapons based on the new round went out in September 1947. By this time, Korsak had left the original EM-1 program and Kazimierz Januszewski had replaced him and had adopted the anglicized name Stefan Kenneth Janson. Janson's new design was given the name EM-2, in spite of being more closely related to the original EM-1. A new EM-1 was developed by Stanley Thorpe while Eric Hall developed an EM-3. Perhaps due to the confusing re-use of the names, these weapons are often referred to by their designer's names, becoming the "Thorpe EM-1", "Janson EM-2" and "Hall EM-3". [4] As if this were not confusing enough, code names were also assigned, the EM-1 "Cobra", EM-2 "Mamba", while the EM-3 did not proceed and did not receive a name, as was the case for an entry from Dennis Burney as the EM-4. [5] [6] [7]
Both the EM-1 and EM-2 were bullpup-style weapons; the magazine and chamber are placed behind the trigger and pistol grip, leading to a shorter overall length (by about 20%) and a better ratio between barrel length and weapon length. The overall length of the EM-2 is 9.5 inches (24 cm) less than the US M14 in spite of its barrel being 2.5 inches (6.4 cm) longer. [5] Both EM-1 and EM-2 used 20-round magazines with "charger" reloads (the charger guide was later omitted from the magazines on EM2s), included the Universal Optical Sight (unit sight) due to the inability to add more traditional sights onto the rifle, had a carrying handle built into the top, could fire semi-automatic or fully automatic and the .280 (7 mm) round was accurate to about 800 yards (730 metres).
The two designs were superficially similar but were internally very different in design and construction, [5] with no parts in common other than sights. The EM-1 used 0.04 in (1.02 mm) thick steel plate pressings for simpler manufacture, a roller locked short recoil mechanism, and was somewhat heavier at about 10 pounds (4.5 kg) with an empty magazine. With uncommon flapper locking and a gas piston above the barrel, EM-2 was similar to Gewehr 43 in its mechanics, although it used a long stroke instead of a short stroke. A fifth design was commissioned from the BSA company, who built prototypes of a more conventional rifle using the same round, the BSA 28P. [5]
The EM-2 was eventually selected as the better design, and was adopted as the British Army's new rifle on 25 April 1951 as the Rifle, Automatic, Calibre .280, Number 9, [8] the designation by which it had been known in the War Office since the American weapons tests of 1950. [9]
In common with other 20th century British designs such as the P14 and SA80, the EM-2 was designed to achieve a high degree of accuracy due to the tradition of British Army emphasis on marksmanship.
With the creation of NATO in 1949, there was a clear preference that NATO forces would have commonality of weapons and ammunition, so weapons designs had to meet with the approval of more than one government, and it was hoped, would be adopted by the organisation as a whole. It was at this point that the US put forth its own designs for NATO standardisation, using the 7.62×51mm NATO round in their prototype T25 and T44 rifles. Matters came to a head in 1951 in a shoot-off conducted at the Aberdeen Proving Grounds, with the US claiming the British round was underpowered, and the British claiming the US round was too powerful to be used in a rifle in full-automatic mode. At the same trials the Belgian .280 FN FAL was also tested.
A series of lengthy debates followed, which were finally settled in an unlikely fashion when Canada stated they would use the British .280 round, but only if the US did as well. It was clear this would never happen. Winston Churchill felt a NATO standard was more important than any qualities of the weapon itself and overturned the decision by the previous Labour Minister of Defence, Manny Shinwell, who had already announced an intention to move to the .280 and the EM-2. During this time, prototype EM-2s were built in several different calibres: Chambons built two for the 7×49mm "Second Optimum" cartridge and another two for the 7.62×51mm NATO. [1] One of the Chambon prototypes was even rebuilt for the US .30-06 cartridge. [1] RSAF-Enfield and BSA built 15 and 10 prototypes for the 7.62×51mm, respectively. [10] Canadian Arsenals Limited also built 10 rifles for the 7×51mm "Compromise" cartridge. [11]
It was clear the EM-2 could not be easily adapted to the powerful 7.62×51mm NATO round [ citation needed ], so the only realistic alternative was to adopt a licensed version of the FN FAL from Fabrique Nationale. Created by Dieudonné Saive, the FAL was itself a re-designed version of FN's own design for an intermediate cartridge rifle using the .280 round (the first prototypes had used the 7.92×33mm Kurz German round from the StG44). However, the FAL was more easily adaptable to handle the more powerful, longer round.
It grew in weight and length as a consequence. Churchill had hoped that with the British Commonwealth and other NATO countries adopting the FN FAL the US Army would do so as well, however the US adopted the T44 (an updated version of the M1 Garand) as the M14, which had won US trials against a more radical experimental rifle, the T25.
In time, the British position on intermediate cartridges was vindicated, the 7.62×51mm proving to be too powerful to be controllable in rifles using automatic mode, smaller cartridges being deemed necessary for that application. Due to combat experience in Vietnam in the mid-1960s, the US adopted the AR-15 as the M16. Chambered for the 5.56×45mm NATO intermediate cartridge, the M16 replaced the M14 which had been adopted little more than a decade earlier.
Some years afterwards, NATO also agreed to move to a smaller round more suitable for full-automatic fire and lighter weapons, ultimately adopting the 5.56×45mm. Prior to committing to the 5.56mm, the British Army conducted additional intermediate cartridge research.
Around 1970, a pair of the original .280 EM-2 were re-barrelled for an experimental 6.25×43mm cartridge. [12] However, the revival of the EM-2 was short-lived as the 6.25mm was dropped for an even smaller 4.85mm cartridge in a completely new rifle, the L64/65 which evolved into the 5.56mm SA80 currently used by the British Army. In spite of having a similar appearance due to its bullpup layout the SA80 is mechanically unrelated to the EM-2; rather it is essentially a bullpup adaptation of the AR-18/SAR-87. However, the concept of an Infantry Personal Weapon which led to the design of the EM-2 [5] was reflected in the SA80 system.
The SA80 is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2023. The A3 variant was first issued in 2018 with several new improvements.
The FN FAL is a battle rifle designed in Belgium in 1953 by Dieudonné Saive and manufactured by FN Herstal.
A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range and ballistic effectiveness.
The Lee–Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the standard service rifle of the British Armed Forces from its official adoption in 1895 until 1957.
An automatic rifle is a type of autoloading rifle that is capable of fully automatic fire. Automatic rifles are generally select-fire weapons capable of firing in semi-automatic and automatic firing modes. Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles.
A battle rifle is a service rifle chambered to fire a fully powered cartridge.
The Fabrique Nationale Model 1949 (often referred to as the FN-49, SAFN, or AFN is an autoloading battle rifle designed by Belgian small arms designer Dieudonné Saive in 1947. It was adopted by the militaries of Argentina, Belgium, the Belgian Congo, Brazil, Colombia, Egypt, Indonesia, Luxembourg, and Venezuela. The selective fire version produced for Belgium was known as the AFN.
The Beta C-Mag is a 100-round capacity drum magazine manufactured by the Beta Company. It was designed by Jim Sullivan and first patented in 1987 and has been adapted for use in numerous firearms firing the 5.56×45mm NATO, 7.62×51mm NATO, and 9×19mm Parabellum cartridges. C-Mag is short for century magazine, referring to its 100-round capacity. It has two drum units, each of which hold half of the cartridges inserted into the magazine. The latest version of the magazine is available with a transparent backing to allow the user to see the number of rounds remaining in the magazine. A C-Mag loaded with 5.56×45mm NATO ammunition typically weighs about 2.1 kg (4.63 lb); a C-Mag loaded with 7.62×51mm NATO ammunition weighs 4.77 kg (10.5 lb).
The L64 was an intermediate calibre British bullpup layout prototype assault rifle developed in the 1970s. At one time it was known as the 4.85 Individual Weapon, a reference to the calibre of the bullet it fired.
The origins of the modern British military rifle are within its predecessor the Brown Bess musket. While a musket was largely inaccurate over 100 yards (91 m), due to a lack of rifling and a generous tolerance to allow for muzzle-loading, it was cheap to produce and could be loaded quickly. The use of volley or mass firing by troops meant that the rate of fire took precedence over accuracy.
The Rifle 7.62mm 2A/2A1 is a 7.62×51mm NATO calibre bolt-action rifle adopted as a reserve arm by the Indian Armed Forces in 1963. The rifle is a variant of the Lee–Enfield rifle. The design of the rifle – initially the Rifle 7.62mm 2A – began at the Rifle Factory Ishapore of the Ordnance Factories Board in India, soon after the Sino-Indian War of 1962.
The .280 British was an experimental rimless bottlenecked intermediate rifle cartridge. It was later designated 7 mm MK1Z, and has also been known as .280/30, .280 Enfield, 7 mm FN Short and 7×43mm.
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges, and therefore is regarded as being "intermediate" between traditional rifle and handgun cartridges.
The TADEN was a British experimental light and medium machine gun firing the .280 in (7 mm) intermediate cartridge. Alongside the bullpup EM-2 rifle design, it formed part of a proposal to reequip the British Army with new small arms which would use a round smaller than the .303 inch which was shown to be impractical for use in a modern assault rifle. The name comes from the designer, Harold Turpin ('T') at the Armament Design Establishment ('AD') and Enfield ('EN').
An assault rifle is a select fire rifle that uses an intermediate-rifle cartridge and a detachable magazine. Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Mkb 42. While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO. By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and submachine guns in most roles. The two most successful modern assault rifles are the AK-47 and the M16 designs and their derivatives.
The SLEM-1 was a semi-automatic battle rifle. The weapon is gas-operated, semi-automatic and has a 10-round magazine.
The 7.62×51mm NATO is a rimless, bottlenecked rifle cartridge. It is a standard for small arms among NATO countries.
The L1A1 Self-Loading Rifle (SLR), also known by the initial Canadian designation C1, or in the U.S. as the "inch pattern" FAL, is a British version of the Belgian FN FAL battle rifle. The L1A1 was produced under licence and adopted by the armed forces of the United Kingdom, Australia, Canada, India, Jamaica, Malaysia, New Zealand, Rhodesia and Singapore.
The 4.85×49mm is an experimental intermediate firearm cartridge made by the United Kingdom for the Individual Weapon Project, which became the SA80 series of small arms.
The T48 was a battle rifle tested by the U.S. military in the mid 1950s during trials to find a replacement for the M1 Garand. It was a license-produced copy of the Belgian FN FAL rifle. The rifle did not enter service, as the U.S. military decided to adopt the M14 rifle instead.
