Persistent Close Air Support
Persistent Close Air Support (PCAS) is a DARPA program that seeks to demonstrate dramatic improvements in close air support (CAS) capabilities by developing a system to allow continuous CAS availability and lethality to Joint Terminal Attack Controllers (JTACs). Overview The program will give JTACs the ability to visualize, select, and employ munitions at the time of their choosing from optionally manned or unmanned aerial attack platforms. PCAS was to demonstrate using an A-10 Thunderbolt II modified for optionally manned operation, however the program did not seek to remove pilots from the cockpit of A-10s or other manned military aircraft. Technologies developed under the program were to transition to both current manned aircraft and the MQ-X next-generation unmanned aircraft. With the cancellation of the MQ-X program, the PCAS program dropped the idea of using an optionally manned A-10, and refocused the effort to allow the JTAC controller to interface with "smart rail" elec ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996. ''The Economist'' has called DARPA "the agency that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AeroVironment Switchblade
The AeroVironment Switchblade is a miniature loitering munition designed by AeroVironment and used by several branches of the United States Armed Forces, United States military. Small enough to fit in a backpack, the Switchblade launches from a tube, flies to the target area, and crashes into its target while detonating its explosive warhead. The name ''Switchblade'' comes from how the spring-loaded wings are folded inside a tube and flipped out once released. Introduced in 2011, the original Switchblade was rebranded the Switchblade300 after the much larger and very different Switchblade600 anti-armour variant was unveiled in 2020. The #Blackwing, Blackwing, an unarmed variant of the Switchblade300, was released in 2015. More than 700 Switchblade 300 drones were sent to Armed Forces of Ukraine, Ukraine by the United States as part of an arms package after the 2022 Russian invasion of Ukraine. History Designed by the United States Air Force Special Operations Command (AFSOC) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-176 Griffin
The AGM-176 Griffin is a lightweight, precision-guided munition developed by Raytheon. It can be launched from the ground or air as a rocket-powered missile or dropped from the air as a guided bomb. It carries a relatively small warhead, and was designed to be a precision low-collateral damage weapon for irregular warfare. It has been used in combat by the United States military during the War in Afghanistan. Development Raytheon and Lockheed Martin Missiles and Fire Control developed the Griffin as a low-cost modular system, using components from earlier projects, including the FGM-148 Javelin and the AIM-9X Sidewinder. It was originally designed to be launched from the US Special Operations Command's MC-130W Dragon Spear gunship and can be guided either by a semi-active laser seeker or with GPS. Its precision combined with a relatively small warhead reduces collateral damage. The munition comes in two versions. Griffin A is an unpowered precision munition that can be dropped ...

MV-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-use, tiltrotor military transport aircraft, military transport and cargo aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed Cruise (aeronautics), cruise performance of a turboprop aircraft. The V-22 is operated by the United States and Japan, and is not only a new aircraft design, but a new type of aircraft that entered service in the 2000s, a tiltrotor compared to fixed wing and helicopter designs. The V-22 first flew in 1989 and after a long development was fielded in 2007. The design combines the vertical takeoff ability of a helicopter with the speed and range of a fixed-wing airplane. The failure of Operation Eagle Claw in 1980 during the Iran hostage crisis underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport ...

Collateral Damage
"Collateral damage" is a term for any incidental and undesired death, injury or other damage inflicted, especially on civilians, as the result of an activity. Originally coined to describe military operations, it is now also used in non-military contexts to refer to negative unintended consequences of an action. Since the development of precision-guided munitions in the 1970s, military forces often claim to have gone to great lengths to minimize collateral damage. Critics of use of the term "collateral damage" see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perceived culpability of military leadership in failing to prevent non-combatant casualties. Collateral damage does not include civilian casualties caused by military operations that are intended to terrorize or kill enemy civilians (e.g., the bombing of Chongqing during World War II and Russian strikes against Ukrainian infrastructure openly described as "ret ...

Inertial Navigation System
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors (magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Design Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object ...

Close Air Support
Close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with special forces if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction, battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not ...

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
