M51 Skysweeper
The M51 Skysweeper (Gun, M51, Antiaircraft or Gun automatic, 75-mm T83E6, and E7, recoil mechanism, and loader rammer) was an anti-aircraft gun deployed in the early 1950s by both the U.S. Army and U.S. Air Force. It was the first such gun to combine a gun laying radar, analog computer (director) and an autoloader on a single carriage. The Skysweeper was introduced just as surface-to-air missiles were being deployed in the long-range role, replacing earlier anti-aircraft artillery systems. These missiles were very large and slow to react, which left short-range engagements to guns. The Army's existing guns were a motley collection of World War II-era systems that were barely effective then, and were considered largely useless against jet-powered aircraft. Missiles replaced all of the larger weapons, while Skysweeper replaced all the smaller ones. The Skysweeper system was used for a relatively short period of time, from the mid to late 1950s in the US, and into the 1960s and 1 ...

Altitude
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or ...

Soo Locks
The Soo Locks (sometimes spelled Sault Locks but pronounced "soo") are a set of parallel locks, operated and maintained by the United States Army Corps of Engineers, Detroit District, that enable ships to travel between Lake Superior and the lower Great Lakes. They are located on the St. Marys River between Lake Superior and Lake Huron, between the Upper Peninsula of the U.S. state of Michigan and the Canadian province of Ontario. They bypass the rapids of the river, where the water falls . The locks pass an average of 10,000 ships per year, despite being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. The winter closure period is used to inspect and maintain the locks. The locks share a name (usually shortened and anglicized as ''Soo'') with the two cities named Sault Ste. Marie, in Ontario and in Michigan, located on either side of the St. Marys River. The Sault Ste. Marie International Bridge between the United States and ...

List Of Nike Missile Locations
The following is a list of Nike missile sites operated by the United States Army. This article lists sites in the United States, most responsible to Army Air Defense Command; however, the Army also deployed Nike missiles to Europe as part of the NATO alliance, with sites being operated by both American and European military forces. U.S. Army Nike sites were also operational in South Korea, Japan and were sold to Taiwan. Leftover traces of the approximately 265 Nike missile bases can still be seen around cities across the United States. As the sites were decommissioned, they were first offered to federal agencies. Many were already on Army National Guard bases who continued to use the property. Others were offered to state and local governments, while others were sold to school districts. The leftovers were offered to private individuals. Many Nike sites are now municipal yards, communications, and FAA facilities, probation camps, and even renovated for use as airsoft gaming and m ...

Nike Ajax
The United States Army's Nike Ajax was the world's first operational guided surface-to-air missile (SAM), entering service in 1954. Nike Ajax was designed to attack conventional bomber aircraft flying at high subsonic speeds and altitudes above . Nike was initially deployed in the US to provide defense against Soviet bomber attacks, and was later deployed overseas to protect US bases, as well as being sold to various allied forces. Some examples remained in use until the 1970s. Originally known simply as Nike, it gained the Ajax as part of a 1956 renaming effort that resulted from the introduction of Hercules. It was initially given the identifier SAM-A-7 (Surface-to-air, Army, design 7) as part of an early tri-service identification system, but later changed to MIM-3 (Mobile Interceptor Missile, design 3) in 1962.Nike was initially designated SAM-G-7, and later changed to SAM-A-7. Originally the Air Force used A while the Army used G, but the Air Force abandoned the 1947 tri-se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Air Defense
United States Army air defense relies on a range of ground launched missiles ranging from hand held to vehicle mounted systems. The Air Defense Artillery is the branch that specializes in anti-aircraft weapons (such as surface-to-air missiles). In the US Army, these groups are composed of mainly air defense systems such as the PATRIOT Missile System, Terminal High Altitude Air Defense, and the Avenger Air Defense system which fires the FIM-92 Stinger missile. The Air Defense Artillery branch descended from the Anti-Aircraft Artillery (part of the Field Artillery) into a separate branch on 20 June 1968. History During World War II, US Army anti-aircraft systems were quite competent. Their smaller tactical needs were filled with four M2 (.50 BMG, .50 caliber) machine guns linked together (known as the "Quad Fifty"), which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft. Although of even less power than Germany's 20 mm syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot.

Sperry Gyroscope Company
Sperry Corporation was a major American equipment and electronics company whose existence spanned more than seven decades of the 20th century. Sperry ceased to exist in 1986 following a prolonged hostile takeover bid engineered by Burroughs Corporation, which merged the combined operation under the new name Unisys. Some of Sperry's former divisions became part of Honeywell, Lockheed Martin, Raytheon Technologies, and Northrop Grumman. The company is best known as the developer of the artificial horizon and a wide variety of other gyroscope-based aviation instruments like autopilots, bombsights, analog ballistics computers and gyro gunsights. In the post-WWII era the company branched out into electronics, both aviation related, and later, computers. History Early history The company was founded in 1910 by Elmer Ambrose Sperry, as the Sperry Gyroscope Company, to manufacture navigation equipment—chiefly his own inventions the marine gyrostabilizer and the gyrocompass—at ...
