Harvest HAWK
The Lockheed Martin (previously Lockheed) KC-130 is a family of the extended-range tanker version of the C-130 Hercules transport aircraft. The KC-130J is the latest variant operated by the United States Marine Corps (USMC), with 48 delivered out of 79 ordered. It replaced older KC-130F, KC-130R, and KC-130T variants for aerial refueling. USMC reserve unit, VMGR-452 operated 12 KC-130T aircraft until May 2021; this was the last USMC reserve unit that operated the legacy KC-130s, completing the corps' transition to the more advanced Super Hercules. Development The KC-130F made its first test flight in January 1960 as the GV-1 under the old Navy designation system. First entering service in 1962, the KC-130F was designed to undertake aerial refueling missions in support of USMC aircraft. It was developed from the Lockheed C-130 Hercules. The newest Hercules, the KC-130J, shares 55 percent of the same airframe as preceding models, but in fact is a greatly improved airplane. It i ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

HC-130J
The Lockheed HC-130 is an extended-range, search and rescue (SAR)/ combat search and rescue (CSAR) version of the C-130 Hercules military transport aircraft, with two different versions operated by two separate services in the U.S. armed forces. The HC-130H Hercules and HC-130J Super Hercules versions are operated by the United States Coast Guard in a SAR and maritime reconnaissance role. The HC-130P Combat King and HC-130J Combat King II variants are operated by the United States Air Force for long-range SAR and CSAR. The USAF variants also execute on scene CSAR command and control, airdrop pararescue forces and equipment, and are also capable of providing aerial refueling to appropriately equipped USAF, US Army, USN, USMC, and NATO/Allied helicopters in flight. In this latter role, they are primarily used to extend the range and endurance of combat search and rescue helicopters. In July 2015, it was announced that the U.S. Forest Service will be receiving some of the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AH-1Z Viper
The Bell AH-1Z Viper is a twin-engine attack helicopter, based on the AH-1W SuperCobra, designed and produced by the American aerospace manufacturer Bell Helicopter. Being one of the latest members of the prolific Bell Huey family, it is also called "Zulu Cobra", based on the military phonetic alphabet pronunciation of its variant letter. The AH-1Z was developed during the 1990s and 2000s as a part of the H-1 upgrade program on behalf of the United States Marine Corps (USMC). It is essentially a modernisation of the service's existing AH-1Ws, and was originally intended to be a rebuild program before subsequent orders were made for new-build helicopters instead. The AH-1Z and Bell UH-1Y Venom utility helicopter share a common tailboom, engines, rotor system, drivetrain, avionics architecture, software, controls and displays for over 84% identical components. Furthermore, it features a four-blade, bearingless, composite main rotor system, uprated transmission, and a new target s ...

Area Denial Weapons
An area denial weapon is a defensive device used to prevent an adversary from occupying or traversing an area of land, sea or air. The specific method used does not have to be totally effective in preventing passage (and sometimes is not) as long as it is sufficient to severely restrict, slow down, or endanger the opponent. Some area denial weapons pose long-lasting risks to anyone entering the area, specifically to civilians, and thus are often controversial. An area denial weapon can be part of an anti-access/area denial (A2/AD) strategy. Historical methods Anti-cavalry In medieval warfare, sharp and sturdy stakes were buried at the bottom of long lines of ditches, pointed end up diagonally, in order to prevent cavalry charges in a given area. Even if the stakes were spotted, soldiers would be forced to dismount and effectively give up their advantage as cavalry as well as becoming easier targets. The correct layout of these extensive lines of ditches and the quality control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mk44 Bushmaster II
The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Northrop Grumman. It is a derivative of the 25 mm M242 Bushmaster, and uses 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API (Armor-Piercing Incendiary), HEI (High-Explosive Incendiary) and APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot-Tracer) variants. The gun can be converted to a caliber of 40x180 mm, which involves changing the barrel and a few key parts, to use the SuperShot 40 cartridge. It can also be converted to use the 30x170 mm RARDEN cartridge. History The Bushmaster II is the standard primary armament of the Bionix-II AFV currently in service with the Singapore Army, the KTO Rosomak in Polish service, and the CV90 AFVs in Finnish, Norwegian and Swiss service.

Precision-guided Munition
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped. Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced. The advent of precision-guided munitions resulted in the renaming of older, low-technology, bombs as "ungu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Griffin (missile)
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 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 5.9 kg warhead reduces collateral damage. The munition comes in two versions. Griffin A is an unpowered precision munition that can be dropped from a rear cargo door or a door-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-114 Hellfire
The AGM-114 Hellfire is an air-to-ground missile (AGM) first developed for anti-armor use, later developed for precision drone strikes against other target types, especially high-value targets. It was originally developed under the name '' Heliborne laser, fire-and-forget missile'', which led to the colloquial name "Hellfire" ultimately becoming the missile's formal name. It has a multi-mission, multi-target precision-strike ability and can be launched from multiple air, sea, and ground platforms, including the Predator drone. The Hellfire missile is the primary class air-to-ground precision weapon for the armed forces of the United States and many other nations. It has also been fielded on surface platforms in the surface-to-surface and surface-to-air roles. Description Most variants are laser-guided, with one variant, the AGM-114L "Longbow Hellfire", being radar-guided. Laser guidance can be provided either from the launcher, such as the nose-mounted opto-electronics of the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overwatch (military Tactic)
Overwatch is a force protection tactic in modern warfare where one small military unit, vehicle or aircraft supports another friendly unit while the latter is executing fire and movement tactics. The term was coined in U.S. military doctrine in the 1950s. An ''overwatching'' unit typically takes a vantage position (usually a high ground or tall structure with good defilade) where it can observe the terrain far ahead, especially likely enemy positions and movements. This allows it to act as a warning system against hostile aggressions and provide effective covering fire for advancing friendly units. See also * Combined arms * Bounding overwatch Bounding overwatch (also known as leapfrogging, moving overwatch, or "The Buddy System") is a military tactic of alternating movement of coordinated units to allow, if necessary, suppressive fire in support of offensive forward "fire and movemen ...

ISTAR
ISTAR stands for intelligence, surveillance, target acquisition, and reconnaissance. In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather. Information is collected on the battlefield through systematic observation by deployed soldiers and a variety of electronic sensors. ''Surveillance'', ''target acquisition'' and ''reconnaissance'' are methods of obtaining this information. The information is then passed to intelligence personnel for analysis, and then to the commander and their staff for the formulation of battle plans. Intelligence is processed information that is relevant and contributes to an understanding of the ground, and of enemy dispositions and intents. Intelligence failures can happen. ISR (Intelligence, surveillance and reconnaissance) ISR is the coordinated and integrated acquisition, processing and provision of timely, accurat ...

Hotel Electric Power
Hotel electric power (HEP) is electricity generated and used by a vehicle, especially a ship, truck, submarine or some turbo prop aircraft without APU generator for purposes other than propulsion such as climate control, communications, entertainment, lighting, refrigeration, water desalination and treatment, etc. The electrical load of such systems is termed the "hotel load". Not having a separate auxiliary power unit saves weight in turbo-prop aircraft such as the ATR 72 and ATR 42, where a propeller brake is used to allow the turbine to continue running without the propeller spinning in "hotel mode". In a railway context a passenger train uses head-end power (also abbreviated to HEP) for functions such as climate control (heating and air conditioning), cooking, lighting, and water heating. See also * Auxiliary power unit * Head-end power In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on ...
