## The Number Sixty-Four  64

.

.

In religion

• The 64th word of the King James Version of the Bible’s Old Testament Genesis is “light”;
• King David prays for deliverance from his enemies in the 64th Psalm;
• The 64 Dakinis or Yoginis are 8 Mother goddesses each with 8 attendants in India religious traditions; each of the 64 can be further correlated to the currents or winds of the human “etheric” body;
• The Lord Shiva has 64 forms or manifestations.

In mathematics

• Sixty-four is the square of 8, the cube of 4, and the sixth power of 2;
• Sixty-four is the smallest number with exactly seven divisors;
• Sixty-four is the lowest positive power of two that is adjacent to neither a Mersenne prime nor a Fermat prime;
• Sixty-four  is the sum of Euler’s totient function for the first fourteen integers;
• Sixty-four is also a dodecagonal number and a centered triangular number;
• In base 10, no integer added up to its own digits yields 64, hence it is a self number;
• Sixty-four is a super-perfect number – a number such that s(s(n))=2n.

.

• Base64
• Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
• Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remain intact without modification during transport.
• Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML.

.

• Graham’s number
• Graham’s number, named after Ronald Graham, is unimaginably larger than other well-known large numbers such as a googol, googolplex, and even larger than Skewes’ number and Moser’s number.
• The number gained a degree of popular attention when Martin Gardner described it in the “Mathematical Games” section of Scientific American in November 1977, writing that, “In an unpublished proof, Graham has recently established … a bound so vast that it holds the record for the largest number ever used in a serious mathematical proof.” The 1980 Guinness Book of World Records repeated Gardner’s claim, adding to the popular interest in this number.
• Specific integers known to be far larger than Graham’s number have since appeared in many serious mathematical proofs (e.g., in connection with Friedman’s various finite forms of Kruskal’s theorem).

In Computing

• 64-bit
• In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory addresses of 64 bits (eight octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code with 64-bit virtual memory addresses

.

• Commodore 64
• The Commodore 64, commonly called C64, CBM 64 (for Commodore Business Machines), or VIC-64, is an 8-bit home computer introduced in January 1982 by Commodore International.
• Volume production started in the spring of 1982, with machines being released on to the market in August at a price of US\$595.
• Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes (65,536 bytes) of RAM, and had favorable sound and graphical specifications when compared to contemporary systems such as the Apple II, at a price that was well below the circa US\$ 1200 demanded by Apple.
• For a substantial period (1983–1986), the C64 dominated the market with between 30% and 40% share and 2 million units sold per year, outselling the IBM PC compatibles, Apple Inc. computers, and Atari 8-bit family computers.
• Sam Tramiel, a later Atari president and the son of Commodore’s founder, said in a 1989 interview “When I was at Commodore we were building 400,000 C64s a month for a couple of years.”

.

• Dragon 64
• The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer (CoCo), and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana.
• The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.

.

• In 1937 another German submarine U-64, a Type IXB U-boat of the Nazi German Kriegsmarine, was ordered in July 1937 and launched in September 1939.
• This U-64 had a very short career and sank no enemy vessels. Having left her home port of Wilhelmshaven for her first war patrol on 6 April 1940, she was intercepted by Allied aircraft seven days later off the coast of Norway during the invasion of that country and was sunk by a bomb from a Fairey Swordfish aircraft of HMS Warspite. Of her crew of 46, eight men died and 38 escaped from the sinking submarine.

.

• K-64
• The K-64 Designation was first given to the first Alfa Class Submarine, launched on April 22, 1969.
• In 1972, the submarine suffered a major reactor problem in the form of a leak of liquid metal coolant. The superheated metal solidified on contact with the colder outside air, freezing and damaging internal components of the reactor. She was removed from service and towed to Severodvinsk.
• The K-64 designation was again given to a Delta IV class submarine launched on February 2, 1986 as the fourth ship of its class, entered in service in the Russian Northern Fleet. The sub was laid down in December 1982 and was built at Sevmash plant in Severodvinsk.

• Six NA-68s ordered by the Royal Thai Air Force were seized before export by the US government in 1941, after the Franco-Thai War and growing ties between Thailand and the Empire of Japan. These aircraft were used by the USAAC as unarmed fighter trainers.
• Seven NA-50s were purchased by the Peruvian Air Force, which nicknamed it Torito (“Little Bull”). The Peruvian NA-50s subsequently saw action during the Ecuadorian-Peruvian War of 1941.

.

• The Grumman G-64/111 Albatross
• The Albatross is easily the largest of Grumman’s series of utility amphibians, and was the only one originally developed specifically for military service.
• The Albatross resulted from a late 1940s US Navy requirement for a general purpose amphibious transport. The first Albatross prototype flew for the first time on October 24 1947, with more than 400 production HU-16s subsequently delivered to the US Navy, US Coast Guard and 12 other nations. Military Albatross missions included general reconnaissance, maritime patrol, anti submarine warfare (in which role it could be armed with torpedoes and depth charges) and search and rescue.
• In the late 1970s, Grumman and major US flying boat operator Resorts International began work on a program to convert the Albatross for civil airline service. The conversion incorporated numerous changes to the basic Albatross, including a 28 seat passenger interior, a galley and provision for a flight attendant, upgraded avionics and other improved systems.
• In all only 13 aircraft were converted, 12 for Resorts International, and 1 for Conoco Oil/Pelita which operated from Singapore. Several of these are still active, together with ex military examples.

.

• AH-64 Apache
• The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew.
• Originally, the Apache started life as the Model 77 developed by Hughes Helicopters for the United States Army’s Advanced Attack Helicopter program to replace the AH-1 Cobra, and was first flown on 30 September 1975.
• The AH-64 was introduced to U.S. Army service in April 1986.
• The AH-64 Apache features a nose-mounted sensor suite for target acquisition and night vision systems; is armed with a 30-millimeter (1.2 in) M230 Chain Gun carried between the main landing gear, under the aircraft’s forward fuselage; and has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has a large amount of systems redundancy to improve combat survivability.
• The first production AH-64D Apache Longbow, an upgraded version of the original Apache, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over 1,000 AH-64s have been produced to date.
• The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands and Singapore; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. U.S. AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip; both British and U.S. Apaches have seen deployments in Afghanistan and Iraq.

.

• Sikorsky S-64 Skycrane
• The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter, the civil version of the United States Army’s CH-54 Tarhe. The S-64 Aircrane is the current production version, manufactured by the Erickson Air-Crane company.
• Erickson Air-Crane purchased the type certificate and manufacturing rights in 1992 and since that date they have become the manufacturer and world’s largest operator of S-64 Aircranes. The Aircrane can be fitted with a 2,650-gallon (~10,000 litre) fixed retardant tank to assist in the control of bush fires, and it has proved itself admirably in this role.
• Erickson is manufacturing new S-64s, as well as remanufacturing existing CH-54s, with each being assigned an individual name, the best-known being “Elvis”, used in fighting fires in Australia alongside “The Incredible Hulk” and “Isabelle”.
• Other operators, such as Siller Brothers, have followed with their Sikorsky S-64E, Andy’s Pride. The Erickson S-64E nicknamed “Olga” was used to lift the top section of the CN Tower into place in Toronto, Canada.
• The S-64 is the first helicopter built with a rear-facing pilot’s seat—this allows the pilot to watch exactly where the load is being placed as he’s flying the helicopter. The feature came in handy in 1993, when an S-64 removed and replaced the Statue of Freedom from the US Capitol building during a renovation. When transporting a big load like that, the S-64 uses an anti-rotation rigging system that prevents the aircraft from twisting and swaying.

.

• T-64
• The T-64 is a Soviet main battle tank, introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served tank divisions, while the T-62 supported infantry in motor rifle divisions. Although the T-62 and the famed T-72 would see much wider use and generally more development, it was the T-64 that formed the basis of more modern Soviet tank designs like the T-80.

.

• The W64 nuclear warhead was the Los Alamos Laboratory’s entry into a brief competition between Lawrence Livermore Laboratory and Los Alamos to design an “enhanced-radiation” nuclear warhead (i.e., a “neutron bomb”) for the United States Army’s MGM-52 Lance tactical surface-to-surface missile.
• The Los Alamos design, the W64, was canceled in September 1964 in favor of Livermore’s W63. In November 1966, the W63 was canceled in favor of the W70, the model that finally entered production.

.

• L64
• The L64 was an intermediate calibre British bullpup layout prototype assault rifle developed in the 1970s. The British Army had considered bullpup designs with intermediate calibre rounds in the 1950s, and officially adopted one of these as .280 British in 1951 in the EM-2 and Taden gun. However, US intransigence during NATO standardization efforts, and Winston Churchill’s interest in standards above all, led to the adoption of the significantly more powerful 7.62×51mm NATO round and the British and Canadian armies adopted the L1A1 SLR, a licensed version of the FN FAL, itself originally designed for the .280.
• In the late 1960s a new L64/65 “Individual Weapon” was developed, outwardly similar to the earlier EM-2, but adopted a firing mechanism very similar to ArmaLite’s latest AR-18 design. The first examples were available in 1972.
• By 1976, NATO was ready to standardize on a small calibre round, and testing of the various rounds head-to-head started in 1977. As designed, the British round out-performed the standard US 5.56 mm. However Fabrique Nationale’s entry based on the 5.56 mm, the “SS-109” performed as well as the British cartridge. In the end it was selected largely due to its similarity with existing US ammunition.
• The L64 pattern was later developed into the SA80 family of weapons, which entered service with the UK in the 1980s.

.

• P-64 Pistol
• The P-64 is a Polish 9mm semi-automatic pistol designed to fire the 9x18mm Makarov cartridge. The pistol was developed in the late 1950s at the Institute for Artillery Research, which later became the Military Institute of Armament Technology.

# Significant Number Factoid Friday – Today The Number Is Eighty-Four 84

“Fight Against Stupidity And Bureaucracy”

.

Time for another significant number factoid.

Today the number is 84.

As usual there is a lot more to it than you might have thought.

If you are into numbers, facts, trivia, or you just like the number 84 then this is for you.

Enjoy.

.

.

In religion

• 84 occurs in the Bible 2 times and once as part of other numbers: — Luke, 2.37 and Nehemiah, 11.18
• 84th Book of Enoch describes the Dream Visions told to Methuselah.

.

.

In Mathematics

• 84 is the sum of the first seven triangular numbers (making it a tetrahedral number), as well as the sum of a twin prime (41 + 43).
• You can count the number 84 in two different ways in this figure. There are 84 diamond-shaped tiles to make this 2-dimensional pattern. Or you can build a 3-dimensional pyramid with 84 blocks.

• A hepteract is a seven-dimensional hypercube with 84 penteract 5-faces.
• The Greek-based numeric prefix octacontatetra- means 84.
• The Latin-based numeric prefix quattuoroctoginta- means 84.
• The Roman numeral for 84 is LXXXIV.

.

In Science

• 84 is the Atomic Weight of Krypton, a noble gas and is present in the air at about 1 ppm. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterized by its brilliant green and orange spectral lines.

.

• 84 is the Atomic Number of Polonium, discovered in 1898 by Marie and Pierre Curie. It is a silvery metal, that has more isotopes than any other element, all of which are radioactive. Polonium has been found in tobacco as a contaminant and in uranium ores.
• Polonium has been used as an assassin’s weapon, notably, in the murder of Alexander Litvinenko, a Russian dissident, in 2006. According to Prof. Nick Priest of Middlesex University, an environmental toxicologist and radiation expert, speaking on Sky News on December 2, Litvinenko was probably the first person ever to die of the acute a-radiation effects of 210Po.

• It has also been suggested that Irène Joliot-Curie was the first person to die from the radiation effects of polonium. She was accidentally exposed to polonium in 1946 when a sealed capsule of the element exploded on her laboratory bench. In 1956 she died from leukemia.
• According to the book The Bomb in the Basement, several death cases in Israel during 1957–1969 were caused by 210Po. A leak was discovered at a Weizmann Institute laboratory in 1957. Traces of 210Po were found on the hands of professor Dror Sadeh, a physicist who researched radioactive materials. Medical tests indicated no harm, but the tests did not include bone marrow. Sadeh died from cancer. One of his students died of leukemia, and two colleagues died after a few years, both from cancer. The issue was investigated secretly, and there was never any formal admission that a connection between the leak and the deaths had existed.
• Abnormally high concentrations of 210Po have been detected in July 2012 in clothes and personal belongings of the Palestinian leader Yasser Arafat, who died in 2004 of uncertain causes. However, the spokesman for the Institut de Radiophysique in Lausanne, Switzerland, where those items were analyzed, stressed that the “clinical symptoms described in Arafat’s medical reports were not consistent with polonium-210 and that conclusions could not be drawn as to whether the Palestinian leader was poisoned or not”, and that “the only way to confirm the findings would be to exhume Arafat’s body to test it for polonium-210.” On 27 November 2012 Arafat’s body was exhumed and samples were taken for separate analysis by experts from France, Switzerland and Russia. Results are expected by April 2013.

• Messier object M84 is situated in the heavily populated inner core of the Virgo Cluster of galaxies. It was discovered and cataloged by Charles Messier on March 18, 1781 when he also cataloged 7 more nebulous objects in the same celestial region. M84 contains a central machine which ejects two small but conspicuous jets, which can be seen in the radio light.

• This object was also target of a 1997 investigation of M84 by the Hubble Space Telescope, shortly after its second service mission (STS-82); it was found that the nucleus of M84 contains a massive central object of 300 million solar masses, concentrated in less than 26 light years from the galaxy’s center. M84 is 60,000 light years away from the Earth.
• The planet Uranus takes 84.01 years to orbit the Sun.

• Asteroid 84 Klio was discovered on August 25, 1865 by Robert Luther at Düsseldorf, Nordrhein-Westfalen, Germany. It has a period of 3 years, 230 days and diameter of 59 miles. Klio [Clio] is one of the 9 Muses of Greco-Roman mythology, daughter of Hermes & Mnemosyne, Klio is the Muse of history.

In air, sea and militaria

• USS Constitution
• The USS Constitution is one of the first six frigates of the U.S. Navy, built by the Naval Act of 1794. These frigates were designed by Joshua Humphreys who designed them to be the major vessels of the young U.S. Navy. For this reason, the Constitution and the others were designed and built bigger, stronger and better armed than the rest of the frigates of the period.
• Initially she was commissioned to provide protection for merchant ships of the United States during the Quasi-War with France, and fight the Barbary Pirates of Tripoli during the War. However, the Constitution is most famous for her actions during the War of 1812 between the United States and Britain, when she captured numerous merchant ships and defeated five warships from Britain: HMS Guerriere, HMS Java, HMS Pictou, HMS Cyane and HMS Levant.
• In the battle with Guerriere she earned the nickname “Old Ironsides” and the public respect and affection that often saved her from being dismantled. This frigate has actively served the United States through the years, and either as flagship in the Mediterranean squadrons and Africa, sailed around the world in 1840. During the Civil War she served as a training ship for the Naval Academy.
• Nowadays Constitution’s mission is to promote understanding of the role of the Navy in times of war as in time of peace through educational outreach, historical demonstrations and active participation in public events. This ship is active, and as such, its crew of 60 officers and sailors members, participates in ceremonies, educational programs and special events while keeping the ship open to visitors year round offering free tours. All personnel assigned is an active member of the Navy and the allocation to this crew is considered a special duty. Traditionally, the command of the ship is assigned to a Navy commander.
• She is to date the oldest ship still afloat and is active worldwide.

• USS Bulkeley (DDG-84)
• USS Bulkeley (DDG-84) is an Arleigh Burke-class destroyer in the United States Navy. She was named after Vice Admiral John D. Bulkeley, who was a World War II Medal of Honor recipient.
• Bulkeley was laid down on 10 May 1999 by Ingalls Shipbuilding and launched on 21 June 2000 in Pascagoula, Mississippi. She was commissioned on 8 December 2001 and is currently homeported at Naval Station Norfolk, Virginia.
• In February 2011, the Bulkeley was involved in a mission to rescue four American citizens from the yacht Quest which was attacked by Somali pirates.
• On 5 March 2011, Bulkeley was involved in rescuing a Japanese oil tanker, MV Guanabara, from Somali pirates while on duty with Combined Task Force 151 off the coast of Oman. Three of the pirates were tried and convicted in Japan, the fourth was turned over to juvenile authorities, as it was determined that he was a minor.
• On 16 May 2011 the Bulkeley responded to a mayday call from the Panamanian flagged very large crude carrier Artemis Glory by dispatching a Blackhawk helicopter to its position. Seeing that a piratical skiff carrying four men was firing upon the Artemis Glory, the Blackhawk engaged the skiff. After killing its four crewmembers, the helicopter withdrew without any casualties to its own crewmembers or that of the Artemis Glory.
• The ship returned to Norfolk on 15 July 2011. During its deployment, it had participated in operations which had captured 75 Somali pirates and had missile strikes by its carrier strike group against the Libyan government.

• No. 84 Squadron of the Royal Flying Corps (RFC) was formed on 7 January 1917 and moved to France in September 1917. It flew the SE.5 over the Western front, at one time based in Bertangles, France until it returned to the UK in August 1919. The squadron was disbanded on 30 January 1920. Its aces included Walter A. Southey.
• The squadron was reformed on 13 August 1920 at Baghdad in Iraq, moving to Shaibah in September, where it remained for the next 20 years. Its initial equipment was DH.9As (until January 1929) and these were replaced by Wapitis (beginning October 1928), Vincents (December 1934) and Blenheims Mk.Is ( February 1939), before moving to Egypt in September 1940. It later operated in Greece, Iraq, and the Western Desert before moving briefly to the Far East. No. 84 Squadron flew the Vultee Vengeance dive bomber from Assam in North-East India but, contrary to some reports, not the Commonwealth Boomerang fighter from New Guinea during World War II (this was done by No. 84 Squadron RAAF). The squadron re-equipped with the Mosquito in February 1945 and in September 1945 with the Bristol Beaufighter. In 1949 No. 84 Squadron flew Bristol Brigands during Operation Firedog.
• The squadron was disbanded again on 20 February 1953, but 204 Squadron was renumbered to No. 84 Squadron on the same day. The squadron was the transport squadron for the RAF in the Middle East till 1971. Its Vickers Valetta flight was detached to become No. 233 Squadron RAF on 1 September 1960 at RAF Khormaksar to provide general transport for the British Army in the Aden Protectorate. The squadron was disbanded yet again at Muharraq on 31 October 1971.
• The squadron was reformed on 17 January 1972 from 1563 Flt and a detachment from 230Sqn with Westland Whirlwind HAR.10s at RAF Akrotiri to aid UN operations and operate search and rescue. It later (March 1982) replaced the Whirlwind with the Westland Wessex HC.2 and later still (June 1984) with the Westland Wessex HU.5C. It was the last squadron to use the Westland Wessex.
• Since January 2003 the squadron has been assigned to British Forces Cyprus at RAF Akrotiri in the search and rescue role using the Bell Griffin HAR2. The helicopters are leased from and maintained by a civilian company. 84 Squadron aircraft are also used for UN duties in maintaining the buffer zone separating Cypriot and Turkish forces. In recognition of this role the aircraft are always unarmed and carry a light blue band around their tail, matching the blue berets of UN peacekeepers.
• 84 Squadron is the only serving squadron never to have been based in the United Kingdom.

• Nakajima Ki-84 Hayate
• The Nakajima Ki-84 Hayate was the result of the Imperial Japanese Army Air Service’s search for an aircraft that was a combination of their own agile Ki-43 Hayabusa and their fast Ki-44 Shoki that could compete with newest allied designs.
• The Ki-84 Hayate (“Gale”) or the Army Type 4 Fighter which was it’s official IJA designation. Hayate was capable of matching the best allied aircraft in the Pacific theater and with its powerful armament to bring down any allied bomber.
• It was numerically the most important fighter serving with the Japanese Army Air Force (JAAF) during the last year of the Pacific War, and was probably the best Japanese fighter aircraft to see large-scale operation during this period of the war. The Hayate was fully the equal of even the most advanced Allied fighters which opposed it, and was often their superior in many important respects. It was well armed and armoured, was fast, and was very manoeuvrable. Although it was generally outnumbered by Allied fighters which opposed it, it nevertheless gave a good account of itself in battles over the Philippines, over Okinawa, and over the Japanese home islands.

• F-84 “Thunderjet”
• Republic Aviation Corporation, Long Island, New York, built P-84 Thunderjets in the 1940s. The Thunderjets were the last of the subsonic straight-wing fighter-bombers to see operational service. They were the aircraft with which flight-refueling techniques for fighters were developed. The first fifteen P-84 production aircraft were fitted with Allison J35A-15 engines and designated YF-84As.
• F-84 “Thunderjet” was the USAF’s first post-war fighter, making its initial flight on February 26, 1946. Gaining its greatest renown during the Korean War, it was used primarily for low-level interdiction missions. The F-84 attacked enemy railroads, bridges, supply depots and troop concentrations with bombs, rockets and napalm. Its maximum speed was 620 mph.

.

• Republic XF-84H
• The Republic XF-84H “Thunderscreech” was an experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome teething aerodynamic deficiencies, resulting in the cancellation of the program.

.

• The Canadair CL-84 “Dynavert”, designated by the Canadian Forces as the CX-131, was a V/STOL turbine tiltwing monoplane designed and manufactured by Canadair between 1964 and 1972. Only four of these experimental aircraft were built with three entering flight testing. Two of the CL-84s crashed due to mechanical failures, but no loss of life occurred as a result of these accidents. Despite the fact that the CL-84 was very successful in the experimental and operational trials carried out between 1972 and 1974, no production contracts resulted.

• After the breakup of the Soviet Union designers faced technical and supply problems. However by the help of Ukrainian Ministry of Machine-Building and Military-Production corpse there were made great preparation works to produce all parts of the new tank indigenously.
• The T-84 Main Battle Tank was publicly presented in United Arabian Emirates in 1995 during international armament exhibition. The new tank called interest in the Pakistan Army and after a long negotiations there was made an agreement to sell 320 T-84 Main Battle Tanks for Pakistan.

.

• M-84
• The M-84 is a main battle tank from the former Yugoslavia .
• In the 1970s, the Yugoslav army decided to develop its own battle tanks and produce. Due to lack of experience of the Yugoslav military industry in tank, it was decided to use the time very advanced Soviet tank T-72 as a base. The rights of the licensed acquired in 1979 by the Soviet Union. Codenamed Kapela was in the armor wrought Ðuro Ðakovic in Slavonski Brod (Croatia) started production. The first prototype was completed in 1983, and mass production began 1984.  Until the outbreak of war in Yugoslavia over 500 pieces for the Yugoslav army were produced. The battle tank M-84 presented a significant improvement of the overall T-72 represents in the following years made more combat performance upgrades and modernizations in different versions.

. .

• Z-84
• The Z-84 again replaced the previous Star SMGs in service, starting in the mid 1980s. The theory was to acquire a gun in 9 mm Parabellum, to match their pistols (and the NATO countries finally). It was offered on the commercial market in 9 mm Largo, but none seem to have been made.
• The Spanish Army, Air Force and Marines supposedly mostly got out of issuing SMGs around the time this emerged — much like the rest of the world — due to the prevalence of lightweight, select-fire rifles. Unlike the previous replacement cycles, therefore, the Z-70B is still in widespread service for those who are issued SMGs (see the sailors at the top of the page). The Z84 is employed by some Guardia, Police and Military units. Aside from general use (such as the boarding party sailors below), in a recent Small Arms Review article, Julio Montes says:
• An interesting weapon in the hands of these naval commandos [the UEBC and UOE] is the locally made Star Z-84… It has proved very efficient and reliable even after being submerged and beat up for longer periods of time. The ever-present MP5 is also found.

.

• Mauser Gewehr 71/84
• On December 2, 1871, the Mauser Infantry Rifle Model 71, was officially adopted by the Prussian government, thus becoming the first bolt-action metallic cartridge rifle to enter German military service.
• The original design single-shot was updated in 1884, refinements including an 8-round tubular magazine designed by Alfred von Kropatschek, making this Germany’s first repeating rifle. This version was designated the Gewehr 71/84 and was officially adopted by the army of Kaiser Wilhelm I on January 31, 1884.
• In the film The Last Samurai the Japanese Imperial Army carries German bolt-action Mauser M1871/84 rifles, in spite of the fact they were supposedly being armed by the U.S. The 1884 models were altered in appearance by film makers to resemble the more period accurate 1871 models.

.

• Carl Gustav Recoiles Rifle
• The Carl Gustav (also Carl-Gustaf and M2CG; pronounced “Carl Gustaf”) is the common name for the 84 mm man-portable reusable multi-role recoilless rifle produced by Saab Bofors Dynamics (formerly Bofors Anti-Armour AB) in Sweden.
• The first prototype of the Carl Gustaf was produced in 1946, and while similar weapons of the era have generally disappeared, the Carl Gustaf remains in widespread use today.
• British troops refer to it as the Charlie G, while Canadian troops often refer to it as the 84, Carl G or Carlo. In U.S. military service it is known as the M3 Multi-role Anti-armor Anti-tank Weapon System (MAAWS) or Ranger Antitank Weapons System (RAWS), but is often called the Gustav or the Goose or simply the Carl Johnson by U.S. soldiers. In Australia it is irreverently known as Charlie Gusto or Charlie Gutsache (guts ache, slang for stomach pain). In its country of origin it is officially named Grg m/48 (Granatgevär or grenade rifle, model 48).
• In recent years, the weapon has found new life in a variety of roles. The British Special Air Service, United States Special Forces and United States Army Rangers use M3s in bunker-busting and anti-vehicle roles, while the German Bundeswehr maintains a small number of M2s for battlefield illumination. Many armies continue to use it as a viable anti-armor weapon, especially against 1950s- and 1960s-era tanks and other armored vehicles still in use worldwide.
• In a well-documented incident during the Falklands War, a Royal Marine attacked an Argentinian corvette (ARA Guerrico) using a Carl Gustav.
• The Carl Gustav was used against Taliban defensive fortifications by soldiers of Princess Patricia’s Canadian Light Infantry in operations in Afghanistan. They developed a new system for firing at night in which a spotter with a night-scope fires tracer ammunition to mark the target for the Carl Gustav gunner.[citation needed]
• Carl Gustav launchers were used by Free Libyan Army during the Libyan civil war in 2011; the weapons being used were either captured or provided by defecting members of the Libyan Army.

.

• M84 Škorpion vz. 61
• The Škorpion vz. 61 is a Czechoslovak 7.65 mm submachine gun developed in 1959 by Miroslav Rybár (1924–1970) and produced under the official designation Samopal vzor 61 (“submachine gun model 1961”) by the Ceská zbrojovka arms factory in Uherský Brod.
• Although it was developed for use with security forces and special forces, the weapon was also accepted into service with the Czechoslovak Army, as a personal sidearm for lower-ranking army staff, vehicle drivers, armored vehicle personnel and special forces. Currently the weapon is in use with the armed forces of several countries as a sidearm.
• The Škorpion was also license-built in Yugoslavia, designated M84. It features a synthetic pistol grip compared to the original version. A civilian, semi-automatic version was also produced, known as the M84A, also available in .380 ACP (9×17mm Short).
