Aerospace Defense Command
Aerospace Defense Command was a major command of the United States Air Force, responsible for continental air defense. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground Forces and "organization and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

First Air Force
The First Air Force (Air Forces Northern; 1 AF-AFNORTH) is a numbered air force of the United States Air Force Air Combat Command (ACC). It is headquartered at Tyndall Air Force Base, Florida. Its primary mission is the air defense of the Contiguous United States (CONUS), United States Virgin Islands and Puerto Rico. Since May 2022, it also provides the Air Force contribution to United States Space Command, as Air Forces Space (AFSPACE), including support functions for NASA human space flight. It was one of the four original pre-World War II numbered air forces formed during the existence of the United States Army Air Corps. It was activated as the Northeast Air District on 18 December 1940, at Mitchel Field, Long Island, New York with a mission of air defense of the Northeastern United States and Great Lakes regions. Its primary mission was the organization and training of new combat units prior to their deployment overseas. It was active in 1941–42; 1942–58; 1966–69; ...

Continental Air Forces
Continental Air Forces (CAF) was a United States Army Air Forces major command, active 1944–1946. It was tasked with combat training of bomber and fighter personnel, and for Continental United States (CONUS) air defense after the Aircraft Warning Corps and Ground Observer Corps were placed in standby during 1944. CAF conducted planning for the postwar United States general surveillance radar stations, and the planning to reorganize to a separate USAF was for CAF to become the USAF Air Defense Command (ADC was headquartered at CAF's Mitchel Field instead of the CAF HQ at Bolling Field.) On 21 March 1946, CAF headquarters personnel and facilities at Bolling Field, along with 1 of the 4 CAF Air Forces ( 2AF—which had its HQ inactivated on 30 March) became Strategic Air Command. US Strategic Air Forces of WWII, e.g., Eighth Air Force and Fifteenth Air Force, transferred later to SAC. Most of the CAF airfields that had not been distributed to other commands when SAC was a ...

Ground-controlled Interception
Ground-controlled interception (GCI) is an air defence tactic whereby one or more radar stations or other observational stations are linked to a command communications centre which guides interceptor aircraft to an airborne target. This tactic was pioneered during World War I by the London Air Defence Area organization, which became the Royal Air Force's Dowding system in World War II, the first national-scale system. The ''Luftwaffe'' introduced similar systems during the war, but most other combatants did not suffer the same threat of air attack and did not develop complex systems like these until the Cold War era. Today the term GCI refers to the style of battle direction, but during WWII it also referred to the radars themselves. Specifically, the term was used to describe a new generation of radars that spun on their vertical axis in order to provide a complete 360 degree view of the sky around the station. Previous systems, notably Chain Home (CH), could only be directed along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Numbered Air Force
A Numbered Air Force (NAF) is a type of organization in the United States Air Force that is subordinate to a List of Major Commands of the United States Air Force, major command (MAJCOM) and has assigned to it operational units such as wings, squadrons, and groups.AFI 38–101, ''Air Force Organization'' . 16 March 2011. A Component Numbered Air Force (C-NAF) has the additional role as an Air Force Component Command exercising command and control over air and space forces supporting a Unified Combatant Command. Unlike MAJCOMs, which have a management role, a NAF is a tactical organization with an operational focus, and does not have the same functional staff as a MAJCOM.

Ground Observer Corps
The Ground Observer Corps (GOC), sometimes erroneously referred to as the Ground ''Observation'' Corps, was the name of two American civil defense organizations during the middle 20th century. World War II organization The first Ground Observer Corps was a World War II Civil Defense program of the United States Army Air Forces to protect United States territory against air attack. The 1.5 million civilian observers at 14,000 coastal observation posts performed naked eye and binocular searches to detect German or Japanese aircraft. Observations were telephoned to filter centers, which forwarded authenticated reports to the Aircraft Warning Service, which also received reports from Lashup Radar Network, Army radar stations. The program ended in 1944. A few Aircraft Warning Service Observation Towers survive as relics. Cold War organization The second Ground Observer Corps, with programmatic aims and methodologies similar to the first, was organized in early 1950, during the Cold W ...

Army Radar Stations
An army (from Old French ''armee'', itself derived from the Latin verb ''armāre'', meaning "to arm", and related to the Latin noun ''arma'', meaning "arms" or "weapons"), ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army. In some countries, such as France and China, the term "army", especially in its plural form "armies", has the broader meaning of armed forces as a whole, while retaining the colloquial sense of land forces. To differentiate the colloquial army from the formal concept of military force, the term is qualified, for example in France the land force is called ''Armée de terre'', meaning Land Army, and the air and space force is called ''Armée de l'Air et de l’Espace' ...

Aircraft Warning Corps
The Aircraft Warning Corps (AWC) was a World War II United States Army Air Force organization for Continental United States air defense. The corps' information centers networked an area's "Army Radar Stations" which communicated radar tracks by telephone, and the information centers also integrated visual reports processed by Ground Observer Corps filter centers. The AWC notified air defense command posts of the First Air Force, Second Air Force, Third Air Force, and Fourth Air Force. These command posts would deploy interceptors which used command guidance to achieve ground-controlled interception. Background and deployment United States electronic attack warning began with the 1929 Air Corps "experimenting with a rudimentary early-warning network at Aberdeen Proving Ground" in Maryland, a 1939 networking demonstration at Twin Lights station (New Jersey), and 2 SCR-270 radar stations during the August 1940 " Watertown maneuvers" (New York). When " Pearl Harbor was attacked, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the enc ...
