RCAF Station St. Margarets
RCAF Station St. Margarets is a former Royal Canadian Air Force station and later a Canadian Forces detachment located in the community of St. Margarets, New Brunswick. It was operational as a Pinetree Line radar station from November 1953 to April 1988 and as a satellite tracking station from 1975 until its closure in 1989. It was involved in Operation Skyshield II in October 1961 which involved tracking "Enemy and Friendly aircraft engaged in a North American wide mock air battle. Personnel from this station and others involved were restricted to base until 16 October 1961 resulting in some personnel postponing personal plans such as weddings. Today the facility has been renamed to James Park in honour of Air Vice-Marshal Arthur Lorne James. James Park is operated by a local development authority which has sold or rented many of the residential units. Most of the military buildings have been demolished since the facility was decommissioned in 1989. History The Royal Canad ...

Pinetree Line
The Pinetree Line was a series of radar stations located across southern Canada at about the 50th parallel north, along with a number of other stations located on the Atlantic and Pacific coasts. Run by North American Aerospace Defense Command (NORAD) (after its creation), over half were staffed by United States Air Force personnel with the balance operated by the Royal Canadian Air Force. The line was the first coordinated system for early detection of a Soviet bomber attack on North America. Its radar technology quickly became outdated, and the line was in full operation only for a short time. History Plans for what would become the Pinetree Line were underway as early as 1946 within the Permanent Joint Board on Defense (PJBD), a Canadian-U.S. organization. However, the costs of running such a system in the post-war era was too high, and instead Canada concentrated on the areas around Ontario and Quebec, while the United States set up stations in the Midwest and alon ...

Back Up Intercept Control
Backup Interceptor Control (BUIC, ) was the Electronic Systems Division 416M System to backup the SAGE 416L System in the United States and Canada. BUIC deployed Cold War command, control, and coordination systems to SAGE radar stations to create dispersed NORAD Control Centers. __TOC__ Background Prior to the SAGE Direction Centers becoming operational, the USAF deployed data link systems at NORAD Control Centers with ground computers for controlling crewed interceptors. After SAGE IBM AN/FSQ-7 Combat Direction Centrals became operational and the Super Combat Centers with improved (digital) computers were cancelled, a backup to SAGE was planned in the event the above-ground SAGE Air Defense Direction Center failed. General Electric AN/GPA-37 Course Directing Group BUIC began with deployment of General Electric AN/GPA-37 Course Directing Groups to several Long Range Radar stations. Units designated included the "U.S. Air Force 858th Air Defense Group (BUIC) hich becamea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loring Air Force Base
Loring Air Force Base was a United States Air Force installation in northeastern Maine, near Limestone and Caribou in Aroostook County. It was one of the largest bases of the U.S. Air Force's Strategic Air Command during its existence, and was transferred to the newly created Air Combat Command in 1992. The base's origins began in 1947 with an order for construction of an airfield by the New England Division of the United States Army Corps of Engineers. The chosen site, in northeastern Maine within both Limestone Township and Caswell Plantation, was the closest point in the continental U.S. to Europe, providing high strategic value during the Cold War. The base was originally named Limestone Army Air Field, and was renamed Limestone Air Force Base following the establishment of the Air Force in 1947. It was named in 1954 for Major Charles J. Loring, Jr., USAF, a Medal of Honor recipient during the Korean War. From 1951 to 1962, it was co-located next to Caribou Air Force Sta ...

Topsham Air Force Station
Topsham Air Force Station is a closed United States Air Force station. It is located north of Brunswick, Maine. It was closed in 1969. History Topsham AFS was initially the headquarters of the Air Defense Command Bangor Air Defense Sector (BaADS), which was activated on 8 January 1957. In 1958 a Semi Automatic Ground Environment (SAGE) Data Center (DC-05) was established at Topsham AFS. The SAGE system was a network linking Air Force (and later FAA) General Surveillance Radar stations into a centralized center for Air Defense, intended to provide early warning and response for a Soviet nuclear attack. A GATR site (R-25) was also constructed at Topsham as part of the 654th Radar Squadron at Brunswick AFS, but was reassigned to the BaADS at Topsham AFS when the 654th RADS was inactivated in 1965. The BaADS was absorbed by the 36th Air Division, being moved to Topsham from Davis Monthan AFB, Arizona on 1 April 1966. DC-02 with its AN/FSQ-7 computer remained under the ...

Semi-Automatic Ground Environment
The Semi-Automatic Ground Environment (SAGE) was a system of mainframe computer, large computers and associated computer network, networking equipment that coordinated data from many radar sites and processed it to produce a single unified image of the airspace over a wide area. SAGE directed and controlled the NORAD response to a possible Soviet air attack, operating in this role from the late 1950s into the 1980s. Its enormous computers and huge displays remain a part of Cold War lore, and after decommissioning were common props in movies such as ''Dr. Strangelove'' and Colossus: The Forbin Project, ''Colossus'', and on science fiction TV series such as ''The Time Tunnel''. The processing power behind SAGE was supplied by the largest discrete component-based computer ever built, the AN/FSQ-7 Combat Direction Central, AN/FSQ-7, manufactured by IBM. Each SAGE Direction Center (DC) housed an FSQ-7 which occupied an entire floor, approximately not including supporting equipment. T ...

Air Vice-Marshal
Air vice-marshal (Air Vce Mshl or AVM) is an air officer rank used by some air forces, with origins from the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air vice-marshal is usually equivalent to the naval rank of rear admiral or a rank of major general in an army. The rank of air vice-marshal is immediately senior to the rank of air commodore and immediately subordinate to the rank of air marshal. Since before the Second World War it has been common for air officers commanding RAF groups to hold the rank of air vice-marshal. In small air forces such as the Royal New Zealand Air Force and the Ghana Air Force, the head of the air force holds the rank of air vice-marshal. The equivalent rank in the Women's Auxiliary Air Force, Women's Auxiliary Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radome
A radome (a portmanteau of "radar" and "dome") is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes spherical, geodesic dome, geodesic, planar, etc. depending on the particular application, using various construction materials such as fiberglass, polytetrafluoroethylene, polytetrafluoroethylene (PTFE)-coated fabric, and others. In addition to radar protection, radomes on aircraft platforms also act as aircraft fairing, fairings that streamline the antenna system, thus reducing drag (physics), drag. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally ...

Red Cliff Air Station
Red Cliff Air Station (Also known as St. Johns) (ID: N-22, C-22) was a General Surveillance Radar station. The remains of which are located north-northeast of St. John's, Newfoundland and Labrador, Canada. It was closed in 1961. History During World War II a US Army-manned battery of two 8-inch railway guns was located at Red Cliff, part of Fort Pepperrell in St. John's. The site was established in 1953 as a general surveillance radar station, funded by the United States Air Force, one of the many that would make up the Pinetree Line of Ground Control Intercept (GCI) radar sites. Northeast Air Command moved the 108th Aircraft Control and Warning Squadron to the station on 1 January 1953. The site was the most eastern ground radar site in North America of the USAF. On 1 August, the 108th was returned to the New York Air National Guard, and the 642d Aircraft Control and Warning Squadron assumed its equipment and personnel. It operated the following radars: * Sear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
