Swedish Nuclear Weapons Program
After World War II, Sweden considered building nuclear weapons to defend themselves against an offensive assault from the Soviet Union. From 1945 to 1972 the government ran a clandestine nuclear weapons program under the guise of civilian defense research at the Swedish National Defence Research Institute (FOA). By the late 1950s the work had reached the point where underground testing was feasible. However, at this time the Riksdag prohibited research and development of nuclear weapons, pledging that research should be done only for the purpose of defense against nuclear attack. They reserved the right to continue development of offensive weapons in the future. In recent years declassified documents have shown that Sweden was much closer to possessing the nuclear bomb than previously thought. By 1965 most of the bomb was already built and another 6 months would have been needed to arm it, had the project been given the green light. Another two bombs would have been built shor ...

Swedish Armed Forces
The Swedish Armed Forces ( sv, Försvarsmakten, "the Defense Force") is the government agency that forms the armed forces of Sweden, tasked with the defense of the country as well as with promoting Sweden's wider interests, supporting international peacekeeping, and providing humanitarian aid. It consists of the Swedish Army, the Swedish Air Force and the Swedish Navy, as well as a military reserve force, the Home Guard. Since 1994, all Swedish military branches are organized within a single unified government agency, headed by the Supreme Commander, even though the individual services maintain their distinct identities. The Swedish Armed Forces is made up of 23,600 active personnel, 11,200 military reserves, 24,000 Home Guard and 5,200 conscripts (set to increase to 8,000 conscripts by 2024) as of 2022. Units of the Swedish Armed Forces are currently on deployment in several international operations either actively or as military observers, including Afghanistan as part o ...

Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Smyth Report
The Smyth Report (officially ''Atomic Energy for Military Purposes'') is the common name of an administrative history written by American physicist Henry DeWolf Smyth about the Manhattan Project, the Allied effort to develop atomic bombs during World War II. The subtitle of the report is ''A General Account of the Development of Methods of Using Atomic Energy for Military Purposes''. It was released to the public on August 12, 1945, just days after the atomic bombings of Hiroshima and Nagasaki on August 6 and 9. Smyth was commissioned to write the report by Major General Leslie R. Groves, Jr., the director of the Manhattan Project. The Smyth Report was the first official account of the development of the atomic bombs and the basic physical processes behind them. It also served as an indication as to what information was declassified; anything in the Smyth Report could be discussed openly. For this reason, the Smyth Report focused heavily on information, such as basic nuclear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsten Schmidt (officer)
Senior Colonel Torsten Andreas Schmidt (23February 1899 – 19December 1996) was a Swedish Army officer. Schmidt was involved in the Swedish Armed Forces' control of the Swedish defense research when it was set up before and during World War II, and when the Swedish nuclear research started. Military career Schmidt was born on 23 February 1899 in Landskrona, Sweden, the son of the banker, vice district judge Martin Schmidt (1858–1942) and his wife Elisabeth Jeanette, née Bruzelius (1867–1911). After passing ''studentexamen'' in 1917, he became a second lieutenant in the Wendes Artillery Regiment (A 3) in 1919 and studied at the Artillery and Engineering College from 1921 to 1924. Schmidt was promoted to lieutenant in 1923 and was lieutenant in the anti-aircraft artillery in 1928. He served as a artillery staff officer from 1932 to 1937 and was promoted to captain in 1934 and was assistant teacher at Artillery and Engineering College from 1934 to 1938. Schmid ...

Supreme Commander Of The Swedish Armed Forces
The Supreme Commander ( sv, överbefälhavaren; acronym: ÖB) is the highest ranked professional military officer in the Swedish Armed Forces, and is by NATO terminology the Swedish chief of defence equivalent. The Supreme Commander is the agency head of the Swedish Armed Forces and formally reports to the Government of Sweden, though normally through the Minister for Defence. The primary responsibilities and duties of the Supreme Commander (and the charter for the Armed Forces) are prescribed in an ordinance issued by the Government. The Supreme Commander is, apart from the honorary ranks held by the King of Sweden and in the past other members of the Swedish Royal Family, by unwritten convention normally the only professional military officer on active duty to hold the highest rank (a four-star General or Admiral). An exception was made 2009-2014 when Håkan Syrén was chairman of the European Union Military Committee. The present Supreme Commander, General Micael Bydén, took ...

Radars
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. ...

Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Rocket Technology
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, struc ...
