Barking Sands Army Airfield
The Pacific Missile Range Facility, Barking Sands is a U.S. naval facility and airport located five nautical miles (9 km) northwest of the central business district of Kekaha, in Kauai County, Hawaii, United States. PMRF is the world's largest instrumented, multi-dimensional testing and training missile range. The US military and its contractors favor its relative isolation, ideal year-round tropical climate and encroachment-free environment (see PMRF Agriculture Preservation Initiative below). It is the only range in the world where submarines, surface ships, aircraft and space vehicles can operate and be tracked simultaneously. There are over of instrumented underwater range and over of controlled airspace. The base itself covers roughly . The base includes a runway with operations and maintenance facilities. It has roughly 70 housing units and various recreational facilities for those who can access the base. The base has support facilities at Port Allen, Makah ...

Kekaha, Hawaii
Kekaha (literally, "the place" in Hawaiian) is a census-designated place (CDP) in Kauai County, Hawaii, United States. The population was 3,715 at the 2020 census, up from 3,175 at the 2000 census. History For most of the 20th century, the Kekaha Sugar Mill (owned by Amfac) was the centerpiece of agriculture on Kauai's west side. The sugar mill had a major influence in Kekaha's development, including banking, employment, transportation, housing and utilities such as water and electricity. The mill employed several generations of local families. It closed in 2000 when the entire sugar industry in Hawaii collapsed. The mill was purchased in 2005 by mainland investors who sold off its heavy machinery to other mills as far away as Africa. Hawaii's first (and only) train robbery occurred here in February 1920, when a masked gunman stopped a slow-moving sugar train and escaped with the locomotive and $11,000 (~$ in ) taken from the labor paymaster on board. Police recovered the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defense Contractor
A defense contractor is a business organization or individual that provides products or services to a military or intelligence department of a government. Products typically include military or civilian aircraft, ships, vehicles, weaponry, and electronic systems, while services can include logistics, technical support and training, communications support, and engineering support in cooperation with the government. Security contractors do not generally provide direct support of military operations. Under the 1949 Geneva Conventions, military contractors engaged in direct support of military operations may be legitimate targets of military interrogation. In the United States, defense contracting has taken an increasingly larger role. In 2009, the Department of Defense spent nearly $316 billion on contracts.Singer, Peter W"The Regulation of New Warfare" [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/APY-10
The AN/APY-10 is an American multifunction radar developed for the U.S. Navy's Boeing P-8 Poseidon maritime patrol and surveillance aircraft. AN/APY-10 is the latest descendant of a radar family originally developed by Texas Instruments, and now Raytheon after it acquired the radar business of TI, for Lockheed P-3 Orion, the predecessor of P-8. The AN/APY-10 mechanically scanned radar is a development of Raytheon's AN/APS-149 radar. Compared to the AN/APS-137, it is smaller in size, lighter, and uses less power. The radar is optimized for maritime, littoral and overland surveillance. The AN/APY-10 is able to provide high resolution radar images in both overland and water modes. Available modes include color weather, synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR), periscope detection, and navigation. ISAR mode is said to be capable of both detecting, imaging and classifying surface targets at long range using a variety of resolutions. AN/APS-80 The AN/AP ...

Niihau
Niihau (Hawaiian language, Hawaiian: ), anglicized as Niihau ( ), is the seventh largest island in Hawaii and the westernmost of the main islands. It is southwest of Kauai, Kauai across the Channels of the Hawaiian Islands#Kaulakahi Channel, Kaulakahi Channel. Its area is . Several intermittent Sink (geography), playa lakes provide wetland habitats for the Hawaiian coot, the Hawaiian stilt, and the Hawaiian duck. The island is designated as critical habitat for ''Brighamia insignis'', an endemic and endangered species of Hawaiian lobelioids, Hawaiian lobelioid. The United States Census Bureau defines Niihau and the neighboring island and State Seabird Sanctuary of Lehua as census tract, Census Tract 410 of Kauai County, Hawaii. Its 2010 United States census, 2010 census population was 170, most of them native Hawaiians. At the 2020 United States census, 2020 census, the population was reported to have fallen to 84. Elizabeth Sinclair purchased Niihau in 1864 for from the Hawai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Airspace
Controlled airspace is airspace of defined dimensions within which air traffic control (ATC) services are provided. The level of control varies with different airspace class, classes of airspace. Controlled airspace usually imposes higher weather minimums than are applicable in uncontrolled airspace. It is the opposite of uncontrolled airspace. Controlled airspace is established mainly for three different reasons: * high-volume air traffic areas, e.g. near airports * Instrument flight rules traffic under ATC guidance * security, e.g. within an air defense identification zone Controlled airspace usually exists in the immediate vicinity of busier airports, where aircraft used in commercial air transport flights are climbing out from or making an approach to the airport, or at higher Above Ground Level, levels where air transport flights would tend to cruise. Some countries also provide controlled airspace almost generally, however in most countries it is common to provide uncon ...

Radar Tracker
A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into Track (navigation), tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different radars or other sensors for data fusion. Role of the radar tracker A classical rotating air surveillance radar system detects target echoes against a background of noise. It reports these detections (known as "plots") in Polar coordinate system, polar coordinates representing the range and bearing of the target. In addition, noise in the radar receiver will occasionally exceed the detection threshold of the radar's constant false alarm rate detector and be incorrectly reported as targets (known as false alarms). The role of the radar tracker is to monitor consecutive updates from the radar system (which typically occur once ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Vehicle
A space vehicle is the combination of a spacecraft and its launch vehicle which carries it into space. The earliest space vehicles were expendable launch systems, using a single or multistage rocket to carry a relatively small spacecraft in proportion to the total vehicle size and mass. An early exception to this, the Space Shuttle, consisted of a reusable orbital vehicle carrying crew and payload, supported by an expendable external propellant tank and two reusable solid-fuel booster rockets. Reusable launch systems are currently being developed by private industry. Early spacecraft or space vehicles were sometimes known as " spaceships", a term which comes from science fiction to designate a hypothetical vehicle which travels beyond low Earth orbit and is 100% reusable, needing only to be refueled like an airplane. History In the 1865 Jules Verne novel ''From the Earth to the Moon'', successful attempts are made to launch three people in a projectile with the goal of ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Ship
Surface combatants (or surface ships or surface vessels) are a subset of naval warships which are designed for warfare on the surface of the water, with their own weapons and armed forces. They are generally ships built to fight other ships, submarines, aircraft or land targets, and can carry out several other missions including counter-narcotics operations and maritime interdiction. Their primary purpose is to engage space, air, surface, and submerged targets with weapons deployed from the ship itself, rather than by crewed carried craft.Naval Transformational Roadmap .
