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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIRCRAFT WARNING CORPS (WWII)
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ba ...

Opana Radar Site
The Opana Radar Site is a National Historic Landmark and IEEE Milestone that commemorates the first operational use of radar by the United States in wartime, during the attack on Pearl Harbor. It is located off the Kamehameha Highway just inland from the north shore of Oahu, Hawaii, south of Kawela Bay. It is not open to the public. History In December 1939, the U.S. military established an Aircraft Warning Service (AWS) using radar to defend American territory. It employed the SCR-270 radar, the first United States long-range search radar created at the Signal Corps laboratories at Fort Monmouth, New Jersey, circa 1937. The radar's operating frequency was 106 megahertz and it had a maximum range of 150 miles, or greater if the equipment was at an elevated site. Under the command of Col. Wilfred H. Tetley the AWS established six mobile radar detector sites on O'ahu at Kawaiola, Wainaae, Ka'a'awa, Koko Head, Schofield Barracks, and Fort Shafter. On Thanksgiving Day in 1941, t ...

Joint Surveillance System
The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America. It replaced the Semi Automatic Ground Environment (SAGE) system in 1983. Overview The JSS consists of long range surveillance radars, primarily operated and maintained by the Federal Aviation Administration (FAA), but providing communication and radar data to both FAA and United States Air Force control centers. Air Route Surveillance Radar FAA equipment is primarily a mixture of Long Range Air Route Surveillance Radars (ARSR) of various types, although some use legacy AN/FPS radars. They are co-located with UHF ground-air-ground (G/A/G) transmitter/receiver (GATR) facilities at many locations. Fourteen sites have VHF radios as well. The GATR facility provides radio access to fighters and Airborne early warning and control (AEW&C) aircraft from the Sector Operations Control Centers. The JSS has been enhanced und ...

SAGE Radar Stations
The SAGE radar stations of Air Defense Command (Aerospace Defense Command after 1968) were the military installations operated by USAF squadrons using the 1st automated air defense environment (Semi-Automatic Ground Environment) and networked by the SAGE System, a computer network. Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.g., the Malmstrom Z-124 radar station was co-located with DC-20. The sector/division radar stations were networked by DCs and Manual Control Centers to provide command, control, and coordination (e.g., at Topsham AFS for the " Bangor North American Air Defense Sector" (image of entrance sign with arrow: "Bangor North American Air Defense Sector")) for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.

Permanent System Radar Stations
The Permanent System ("P system") was a 1950s radar network ("P radar net") used for the CONUS "manual air defense system" and which had a USAF aircraft control and warning (AC&W) organization of personnel and military installations with radars to allow Air Defense Command ground-controlled interception of Cold War bombers attacking the United States. Planning As with the World War II CONUS radar network of "Army Radar Stations", Aircraft Warning Corps information centers, Ground Observer Corps filter centers, and Fighter Control Centers ("inactivated...in April 1944"), a post-war system was planned to assess bomber attacks and for dispatching interceptors. The Distant Early Warning Line was "first conceived—and rejected—in 1946", General Stratemeyer forwarded an air defense plan to General Spaatz in November 1946, and in the spring and summer of 1947, 3 Air Defense Command (ADC) Aircraft Control and Warning (AC&W) plans had gone unfunded: e.g., the April 8, 1947, "air d ...

Lashup Radar Network
The Lashup Radar Network was a United States Cold War radar netting system for air defense surveillance which followed the post-World War II "five-station radar net" and preceded the "high Priority Permanent System". ROTOR was a similar expedient system in the United Kingdom. Background United States electronic attack warning began with a 1939 networking demonstration at Twin Lights station NJ, and 2 SCR-270 radar stations during the August 1940 " Watertown maneuvers" (NY). When "Pearl Harbor was attacked, here were 8 CONUSearly-warning stations" (ME, NJ, & 6 in CA), and Oahu's Opana Mobile Radar Station had 1 of 6 SCR-270s. CONUS "Army Radar Station" deployments for World War II were primarily for coastal anti-aircraft defense, e.g., L-1 at Oceanside CA, J-23 at Seaside OR (Tillamook Head), and B-30 at Lompoc CA; and "the AAF...inactivated the aircraft warning network in April 1944." In 1946 the Distant Early Warning Line was "first conceived—and rejected". By 1948 there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Equipment Facility J-33
Ground Equipment Facility J-33 is a Federal Aviation Administration (FAA) radar station of the Joint Surveillance System's Western Air Defense Sector (WADS) with an Air Route Surveillance Radar (ARSR-4). The facility was previously a USAF general surveillance radar station during the Cold War. The site is located on West Peak of Mount Tamalpais, in Marin County, California. History The Cold War radar station near Mill Valley was one of twenty-eight stations approved by the United States Secretary of Defense on July 21, 1950, as part of the Permanent System radar network (the Corps of Engineers managed construction for the USAF). Construction began at an upper location of the former World War II Mount Tamalpais Radar Site of the Aircraft Warning Service (the World War II information center of the AWC was located at tbd for plotting radar tracks in the San Francisco area).

Seaside, Oregon
Seaside is a city in Clatsop County, Oregon, United States, on the coast of the Pacific Ocean. The name Seaside is derived from ''Seaside House'', a historic summer resort built in the 1870s by railroad magnate Ben Holladay. The city's population was 6,457 at the 2010 census. History The Clatsop were a historic Native American tribe that had a village named ''Ne-co-tat'' (in their Chinook language) in this area. Indigenous peoples had long inhabited the coastal area. About January 1, 1806, a group of men from the Lewis and Clark Expedition built a salt-making cairn at the site later developed as Seaside. The city was not incorporated until February 17, 1899, when coastal resort areas were being settled. It is about by car northwest of Portland, Oregon, a major population center. In 1912, Alexandre Gilbert (1843–1932) was elected Mayor of Seaside. Gilbert was a French immigrant, a veteran of the Franco Prussian War (1870-1871). After living in San Francisco, California an ...

Tillamook Head
Tillamook Head is a high promontory on the Pacific coast of northwest Oregon in the United States. It is located in west-central Clatsop County, approximately 5 mi (8 km) southwest of Seaside. The promontory forms a steep rocky bluff on the ocean, approximately 1,200 ft (366 m) high, forested with Sitka spruce. It is located in Ecola State Park. The promontory is named after the Tillamook, a Salishan-speaking tribe of Native Americans who inhabited the coast south of the promontory in the 19th century. In 1806, Captain William Clark and 12 members of the Corps of Discovery documented their journey south from Fort Clatsop, hiking over the promontory where they encountered a beached whale. Geology Tillamook Head is a tilted remnant of a flow of 15-million-year-old Columbia River basalt. The lava welled up near modern-day Idaho, and flooded down the Columbia Gorge. It spread along the Oregon Coast to Tillamook Head, cooling to a 600-foot thick basalt sill. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
