| The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA), as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. Five complete Shuttle systems were built and used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST); conducted science experiments in orbit; and participated in construction and servicing of the International Space Station. The Shuttle fleet's total mission time was 1322 days, 19 hours, 21 minutes and 23 seconds. |

the m1a1 thompson is an american submachine gun developed in 1914, but it wasn't used in ww1 so the american troops got to use it in ww2 instead. its mediocre rate of fire and deadly accuracy can spray down at least 5 hostile troops in one mag

The AK-47, or AK as it is officially known (also known as the Kalashnikov) is a selective-fire (semi-automatic and automatic), gas-operated 7.62×39 mm assault rifle, developed in the Soviet Union by Mikhail Kalashnikov. It is officially known in the Soviet documentation as Avtomat Kalashnikova (Russian: Автомат Калашникова).
Design work on the AK-47 began in the last year of World War II (1945). In 1946, the AK-47 was presented for official military trials, and in 1948, the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the ### ########### or "folding"), which was equipped with an underfolding metal shoulder stock. In the spring of 1949, the AK-47 was officially accepted by the Soviet Armed Forces[8] and used by the majority of the member states of the Warsaw Pact.
Even after almost seven decades, the model and its variants remain the most popular and widely used assault rifles in the world because of their substantial reliability under harsh conditions, low production costs compared to contemporary Western weapons, availability in virtually every geographic region and ease of use. The AK-47 has been manufactured in many countries and has seen service with armed forces as well as irregular forces worldwide, and was the basis for developing many other types of individual and crew-served firearms. As of 2004, "Of the estimated 500 million firearms worldwide, approximately 100 million belong to the Kalashnikov family, three-quarters of which are AK-47s".

The M134 Minigun is a 7.62×51mm NATO, six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute) which can also fire at a high sustained rate.[1] It features Gatling-style rotating barrels with an external power source, normally an electric motor. The "Mini" in the name is in comparison to larger caliber designs that use a rotary barrel design, such as General Electric's earlier 20-millimeter M61 Vulcan, and "gun" for the use of rifle caliber bullets instead of shells used by an autocannon. The Minigun is used by several branches of the U.S. military. Versions are designated M134 and XM196 by the United States Army, and GAU-2/A and GAU-17/A by the U.S. Air Force and U.S. Navy. "Minigun" refers to a specific model of weapon that General Electric originally produced, but the term "minigun" has popularly come to refer to any externally powered rotary-style gun of rifle caliber. The term is sometimes used loosely to refer to guns of similar rates of fire and configuration regardless of power source and caliber.

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion (thermonuclear weapon). Both reactions release vast quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released the same amount of energy as approximately 20,000 tons of TNT (84 TJ). The first thermonuclear ("hydrogen") bomb test released the same amount of energy as approximately 10 million tons of TNT (42 PJ).
A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can produce an explosive force comparable to the detonation of more than 1.2 million tons of TNT (5.0 PJ).[1] A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. Nuclear weapons are considered weapons of mass destruction, and their use and control have been a major focus of international relations policy since their debut.
Nuclear weapons have been used twice in nuclear warfare, both times by the United States against Japan near the end of World War II. On August 6, 1945, the U.S. Army Air Forces detonated a uranium gun-type fission bomb nicknamed "Little Boy" over the Japanese city of Hiroshima; three days later, on August 9, the U.S. Army Air Forces detonated a plutonium implosion-type fission bomb codenamed "Fat Man" over the Japanese city of Nagasaki. The bombings resulted in the deaths of approximately 200,000 civilians and military personnel from acute injuries sustained from the explosions.[2] The ethics of the bombings and their role in Japan's surrender remain the subject of scholarly and popular debate.
Since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated on over two thousand occasions for the purposes of testing and demonstration. Only a few nations possess such weapons or are suspected of seeking them. The only countries known to have detonated nuclear weapons—and acknowledge possessing them—are (chronologically by date of first test) the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea. Israel is also believed to possess nuclear weapons, though in a policy of deliberate ambiguity, it does not acknowledge having them. Germany, Italy, Turkey, Belgium and the Netherlands are nuclear weapons sharing states.[3][4][5] South Africa is the only country to have independently developed and then renounced and dismantled its nuclear weapons.[6]
The nuclear non-proliferation treaty aimed to reduce the spread of nuclear weapons, but its effectiveness has been questioned, and political tensions remained high in the 1970s and 1980s. Modernisation of weapons continues to occur.[7]

| What have I done The Boeing 737 is an American short- to medium-range twinjet narrow-body airliner. Originally developed as a shorter, lower-cost twin-engine airliner derived from Boeing's 707 and 727, the 737 has developed into a family of ten passenger models with capacities from 85 to 215 passengers. The 737 is Boeing's only narrow-body airliner in production, with the 737 Next Generation (-700, -800, and -900ER) variants currently being built. Production has also begun on the re-engined and redesigned 737 MAX, which is set to enter service in 2017. Originally envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered airline service in February 1968 at Lufthansa. Next, the lengthened 737-200 entered service in April ##### In the 1980s Boeing launched the ##### ##### and -500 models, subsequently referred to as the Boeing 737 Classic series. The 737 Classics added capacity and incorporated CFM56 turbofan engines along with wing improvements. |

The OTs-03 SVU (Russian: Снайперская винтовка укороченная, Snayperskaya Vintovka Ukorochennaya, Sniper Rifle Shortened) is a bullpup configuration of the SVD sniper rifle. The SVU was developed to meet the needs of the security forces of the Russian Ministry of Internal Affairs, such as OMON. The SVU was first seen in use in the First Chechen War. Originally, the plan was to just slightly modernize the aging SVD, but the designers eventually realised that the configuration of the weapon would have to be completely altered, leading to the creation of the SVU. A special muzzle brake was added that could absorb up to 40% of the recoil energy and an elastic butt stock with lamellar spring was non-rigidly attached to the receiver. The acoustics of the rifle were also improved by adding a sound suppressor. The other main improvements made to the SVU over the SVD include replacement of the butt stock, pistol grip, trigger and the mounting for the sight; and shortening the barrel by 100 mm achieved perfect balance for the weapon. Around 1991, the Russians developed a slight variant of the OTs-03, the OTs-03A (SVU-A). Whereas the SVU is semi-automatic, the SVU-A (the A stands for automatic) is a fully automatic rifle. In this rifle, the center of gravity was moved forward by the addition of a forward extended bipod mounted on the receiver. Developing 20 and 30 round magazines increased the capacity of the magazine so that it could be used effectively in full automatic mode; and better optics were incorporated into the SVU-A to replace the previous units, which had been left almost untouched since the SVD. Though it has folding iron sights, the SVU is almost always used with the PSO-1 scope with illuminated reticle, but other Russian scopes can also be mounted. The PSO-1 reticle is almost unique in the world of sniper scopes, in that its rangefinders are in the lower left, chevrons for bullet drop compensation are found in the middle, and stadia marks for windage to the left and right of the center reticule. The reticle is also illuminated by radioactive tritium instead of a small battery-powered lamp. The SVU also comes with an adjustable bipod. It has an integral flash hider and muzzle brake. A bayonet may be fitted under the forestock.
