Light Observation Helicopter
The Light Observation Helicopter (LOH) program was a United States Army program to evaluate, develop and field a light scout helicopter to replace the Army's aging Bell OH-13 Sioux. It gained impetus with the advent of the Vietnam War, and was aided by advances in helicopter technology, specifically the development of the turboshaft engine. History In July 1953, the Office of Lieutenant General (United States), Lieutenant General John E. Dahlquist, Chief, Army Field Forces (AFF), forwarded desirable military characteristics for a two-place reconnaissance helicopter to Army Headquarters. Nearly a year later, in May 1954, Dahlquist's office once again emphasized the need for replacement aircraft and recommended procurement of troop test quantities of the YH-32 Hornet, YH-32. Preliminary evaluation of the YH-32 design revealed that the aircraft was unsuitable for the mission, and the tests were canceled.Weinert 1991, p. 205. In 1955, the Army Field Forces were transformed into t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casualty Evacuation
Casualty evacuation, also known as CASEVAC or by the callsign Dustoff or colloquially Dust Off, is a military term for the emergency patient evacuation of casualty (person), casualties from a combat zone. Casevac can be done by both ground and air. "DUSTOFF" is the callsign specific to U.S. Army Air Ambulance units. CASEVACs by air today are almost exclusively done by helicopter, a practice begun on a small scale toward the end of World War II; before that, STOL aircraft, such as the Fieseler Fi 156 or Piper J-3 were used. The primary difference between a CASEVAC and a medical evacuation (MEDEVAC) is that a MEDEVAC uses a standardized and dedicated vehicle providing en route care, while a CASEVAC uses non-standardized and non-dedicated vehicles that may or may not provide en route care. CASEVACs are commonly referred to as "a lift/flight of opportunity". If a corpsman/medic on the ground calls for a CASEVAC, the closest available unit with space could be called to assist, reg ...

Operation Eagle Claw
Operation Eagle Claw ( Persian: عملیات پنجه عقاب) was a failed U.S. Department of Defense attempt to rescue 52 embassy staff held captive by Revolutionary Iran on 24 April 1980. It was ordered by US President Jimmy Carter after the staff were seized at the Embassy of the United States, Tehran. The operation, one of Delta Force's first, encountered many obstacles and failures and was subsequently aborted. Eight helicopters were sent to the first staging area called ''Desert One'', but only five arrived in operational condition. One had encountered hydraulic problems, another was caught in a sand storm, and the third showed signs of a cracked rotor blade. During the operational planning, it was decided that the mission would be aborted if fewer than six helicopters remained operational upon arrival at the Desert One site, despite only four being absolutely necessary. In a move that is still discussed in military circles, the field commanders advised President Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MH-60 Black Hawk
The Sikorsky UH-60 Black Hawk is a four-blade, twin-engine, medium-lift military utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted a design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the ''YUH-60A'' and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61. Named after the Native American war leader Black Hawk, the UH-60A entered service with the U.S. Army in 1979, to replace the Bell UH-1 Iroquois as the Army's tactical transport helicopter. This was followed by the fielding of electronic warfare and special operations variants of the Black Hawk. Improved UH-60L and UH-60M utility variants have also been developed. Major variants include the Navy's SH-60 Seahawk, the Air Force's HH-60 Pave Hawk, the Coast Guard's MH-60 Jayhawk and the civilian S-70. In addition to use by U.S. armed force ...

Special Forces
Special forces or special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during World War II, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including Airborne forces, airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, Covert operations, covert ops, Direct action (military), direct action, Hostage crises, hostage rescue, high-value targets/Manhunt (military), manhunt, intelligence, surveillance, target acquisition, and reconnaissance, intelligence operations, Mobility (military), mobility o ...

Gunship
A gunship is a military aircraft armed with heavy aircraft guns, primarily intended for attacking ground targets either as airstrike or as close air support. In modern usage the term "gunship" refers to fixed-wing aircraft having laterally-mounted heavy armaments (i.e. firing to the side) to attack ground or sea targets. These gunships are configured to circle the target instead of performing strafing runs. Such aircraft have their armament on one side harmonized to fire at the apex of an imaginary cone formed by the aircraft and the ground when performing a pylon turn ( banking turn). The term "gunship" originated in the mid-19th century as a synonym for gunboat and also referred to the heavily armed ironclad steamships used during the American Civil War. The term helicopter gunship is commonly used to describe armed helicopters. World War II aviation Bomber escort During 1942 and 1943, the lack of a usable escort fighter for the United States Army Air Forces in the Eu ...

Rolls-Royce Model 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
