The Boeing Vertol CH-46 Sea Knight is an American medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing.
Multiple designation systems have been used to specify United States military aircraft. The first system was introduced in 1911 by the United States Navy, but was discontinued six years later; the first system similar to that used today was designed in 1919 when the US Army's Aeronautical Division became the United States Army Air Service. Before this, aircraft were put into service under their manufacturers' designations.
The de Havilland Canada DHC-4 Caribou is a Canadian specialized cargo aircraft with short takeoff and landing (STOL) capability. The Caribou was first flown in 1958 and although mainly retired from military operations, is still in use in small numbers as a rugged bush airplane.
The Martin P5M Marlin, built by the Glenn L. Martin Company of Middle River, Maryland, was a twin piston-engined flying boat that entered service in 1951, and served into the late 1960s with the United States Navy performing naval patrols. It also served with the United States Coast Guard and the French Navy. 285 were produced.
The Fairchild PT-19 is an American monoplane primary trainer aircraft that served with the United States Army Air Forces, RAF and RCAF during World War II. Designed by Fairchild Aircraft, it was a contemporary of the Kaydet biplane trainer, and was used by the USAAF during Primary Flying Training. As with other USAAF trainers of the period, the PT-19 had multiple designations based on the powerplant installed.
The Tri-Service aircraft designation system is a unified system introduced in 1962 by the United States Department of Defense for designating all U.S. military aircraft. Previously, the U.S. armed services used separate nomenclature systems.
New York Airways was an American helicopter airline in the New York City area, founded in 1949 as a mail and cargo carrier. On 9 July 1953 it may have been the first scheduled helicopter airline to carry passengers in the United States, with headquarters at LaGuardia Airport. Although primarily a helicopter airline operator with scheduled passenger operations, New York Airways also flew fixed wing aircraft, such as the de Havilland Canada DHC-6 Twin Otter 19-passenger STOL twin turboprop aircraft.
The Piasecki H-21 Workhorse/Shawnee is an American helicopter, the fourth of a line of tandem rotor helicopters designed and built by Piasecki Helicopter. Commonly called "the flying banana", it was a multi-mission helicopter, capable of being fitted with wheels, skis or floats.
The Piasecki HUP Retriever/H-25 Army Mule is a compact single radial engine, twin overlapping tandem rotor utility helicopter developed by the Piasecki Helicopter Corporation of Morton, Pennsylvania. Designed to a United States Navy specification, the helicopter was produced from 1949 to 1954, and was also used by the United States Army and foreign navies. The HUP/H-25 was the first helicopter to be produced with an autopilot and also the first to perform a loop.
The Hiller VZ-1 Pawnee was a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a platform upon which the single pilot shifted body weight for directional control. The platform was developed starting in 1953 under an Office of Naval Research (ONR) contract to Hiller Aircraft, and flew successfully beginning in 1955.
From 1922 until 1962, the United States Navy, the United States Marine Corps and the United States Coast Guard used a system to designate their aircraft that included information about a craft's role and its manufacturer. For a listing of all such designations, see the list of United States Navy aircraft designations (pre-1962).
The Fairchild 71 was an American high-wing monoplane passenger and cargo aircraft built by Fairchild Aircraft and later built in Canada by Fairchild Aircraft Ltd. (Canada) for both military and civilian use as a rugged bush plane.
The Fairchild VZ-5 was an experimental VTOL aircraft built in the 1950s. The VZ-5 was designed by Fairchild Aircraft for research use by the United States Army.
The Ryan VZ-3 Vertiplane, also known by the company designation Ryan Model 92 was an American experimental vertical/short take-off (VSTOL) aircraft built by the Ryan Aeronautical Company for the United States Army.
The United States Army Aviation Museum is an aviation museum located on Fort Novosel near Daleville, Alabama. It has the largest collection of helicopters held by a museum in the world. The museum features some 50 aircraft on public display with aviation artifacts ranging from a replica of the Wright brothers' Model B military biplane to an RAH-66 Comanche. The museum has over 160 aircraft in its collection and holds 3,000 historical items.
The HZ-1 Aerocycle, also known as the YHO-2 and by the manufacturer's designation DH-5 Aerocycle, was an American one-man "personal helicopter" developed by de Lackner Helicopters in the mid-1950s. Intended to be operated by inexperienced pilots with a minimum of 20 minutes of instruction, the HZ-1 was expected to become a standard reconnaissance machine with the United States Army. Although early testing showed that the craft had promise for providing mobility on the atomic battlefield, more extensive evaluation proved that the aircraft was in fact too difficult to control for operation by untrained infantrymen, and after a pair of crashes the project was abandoned. A single model of the craft was put on display.
The Fleetwings BQ-2 was an early expendable unmanned aerial vehicle — referred to at the time as an "assault drone" — developed by Fleetwings during the Second World War for use by the United States Army Air Forces. Only a single example of the type was built; the aircraft was deemed too expensive for service and was cancelled after a brief flight testing career.
