Lockheed Martin RQ-3 DarkStar
The RQ-3 DarkStar (known as Tier III- or "Tier three minus" during development) is an unmanned aerial vehicle (UAV). Its first flight was on March 29, 1996. The Department of Defense terminated DarkStar in January 1999, after determining the UAV was not aerodynamically stable and was not meeting cost and performance objectives. Design and development The RQ-3 DarkStar was designed as a "High-Altitude Long Endurance, high-altitude endurance UAV", and incorporated stealth aircraft technology to make it difficult to detect, which allowed it to operate within heavily defended airspace, unlike the Northrop Grumman RQ-4 Global Hawk, which is unable to operate except under conditions of air supremacy. The DarkStar was fully autonomous: it could take off, fly to its target, operate its sensors, transmit information, return and land without human intervention. Human operators, however, could change the DarkStar's flight plan and sensor orientation through radio or satellite relay. The ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.

Dark Star USAF
Darkness is the condition resulting from a lack of illumination, or an absence of visible light. Human vision is unable to distinguish colors in conditions of very low luminance because the hue-sensitive photoreceptor cells on the retina are inactive when light levels are insufficient, in the range of visual perception referred to as scotopic vision. The emotional response to darkness has generated metaphorical usages of the term in many cultures, often used to describe an unhappy or foreboding feeling. "Darkness" may also refer to night, which occurs when the Sun is more than 18° below the horizon. Scientific Perception The perception of darkness differs from the mere absence of light that sometimes lead to afterimages. In perceiving, the eye is active, and the part of the retina that is unstimulated produces a complementary afterimage. Physics In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. ...

Unmanned Military Aircraft Of The United States
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. It has been reported that the armed forces of more than 100 countries have approximately 170 different types of drones in service. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) **Self-driving truck **Driverless tractor * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft, either fixed-wing or rotorwing, commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Mediu ...

Unmanned Combat Aerial Vehicle
An unmanned combat aerial vehicle (UCAV), also known as a combat drone, fighter drone or battlefield UAV, is an unmanned aerial vehicle (UAV) that is used for intelligence, surveillance, target acquisition, and reconnaissance and carries aircraft ordnance such as missiles, anti-tank guided missiles (ATGMs), and/or Aerial bomb, bombs in hardpoints for drone strikes. These drones are usually under real-time human control, with varying levels of autonomy. UCAVs are used for reconnaissance, attacking targets and returning to base; unlike Loitering munition, kamikaze drones which are only made to explode on impact, or unmanned surveillance and reconnaissance aerial vehicle, surveillance drones which are only for gathering intelligence. Aircraft of this type have no onboard human pilot. As the Radio control, operator runs the vehicle from a remote terminal, equipment necessary for a human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft.

EADS Barracuda
The EADS Barracuda was a jet powered unmanned aerial vehicle (UAV), EADS, used for the role of aerial reconnaissance and also combat (like UCAV). The aircraft was a joint venture between Germany and Spain. Development of the project was stopped after the first prototype crashed at Mar Menor while approaching for landing during a test flight. The program was resumed in 2008, with a second prototype being completed in November 2008. The rebuilt Barracuda underwent a series of successful flight tests in Goose Bay, Canada during July 2009, followed by further flight campaigns in 2010 and 2012. The Barracuda's primary competition was Dassault nEUROn for strategic and defensive contracts. Both were stealthy and had a maximum air speed of around Mach 0.85. While Germany and Spain were behind the Barracuda, France, Italy, Sweden, Switzerland, Greece, and Spain as well funded the nEUROn. It had an operating ceiling of around and carried a maximum payload of 300 kg. It was retir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
