PQ 17 was the code name for an Allied Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by German forces on 1 July, after which it was shadowed continuously and attacked. The First Sea Lord Admiral Dudley Pound, acting on information that German surface units, including the German battleship Tirpitz, were moving to intercept, ordered the covering force built around the Allied battleships HMS Duke of York and the USS Washington away from the convoy and told the convoy to scatter. Because of vacillation by Oberkommando der Wehrmacht, the Tirpitz raid never materialised. The convoy was the first large joint Anglo-American naval operation under British command; in Churchill's view this encouraged a more careful approach to fleet movements.
USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole on 3 August 1958. Her initial commanding officer was Eugene "Dennis" Wilkinson, a widely respected naval officer who set the stage for many of the protocols of today's Nuclear Navy of the US, and who had a storied career during military service and afterwards.
The GIUK gap is an area in the northern Atlantic Ocean that forms a naval choke point. Its name is an acronym for Greenland, Iceland, and the United Kingdom, the gap being the two stretches of open ocean between these three landmasses. It separates the Norwegian Sea and the North Sea from the open Atlantic Ocean. The term is typically used in relation to military topics. The area has for some nations been considered strategically important since the beginning of the 20th century.
Sound Surveillance System (SOSUS) was the original name for a submarine detection system based on passive sonar developed by the United States Navy to track Soviet submarines. The system's true nature was classified with the name and acronym SOSUS classified as well. The unclassified name Project Caesar was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. The name changed to Integrated Undersea Surveillance System (IUSS) in 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems. The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance Pacific, and personnel were able to wear insignia reflecting the mission.
Ice Station Zebra is a 1963 thriller novel written by Scottish author Alistair MacLean. It marked a return to MacLean's classic Arctic setting. After completing this novel, whose plot line parallels real-life events during the Cold War, MacLean retired from writing for three years. In 1968 it was loosely adapted into a film of the same name.
Skyhook, sky hook or skyhooks may refer to:
Mid-air retrieval is a technique used in atmospheric reentry when the reentering vehicle is incapable of a satisfactory unassisted landing. The vehicle is slowed by means of parachutes, and then a specially-equipped aircraft matches the vehicle's trajectory and catches it in mid-air.
The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with two gaps with no sailings between July and September 1942, and March and November 1943.
Skyhook balloons were high-altitude balloons developed by Otto C. Winzen and General Mills, Inc. They were used by the United States Navy Office of Naval Research (ONR) in the late 1940s and 1950s for atmospheric research, especially for constant-level meteorological observations at very high altitudes. Instruments like the Cherenkov detector were first used on Skyhook balloons.
The Russian commando frogmen, informally called "commando frogmen" in civilian media, are a Russian Naval Spetsnaz unit under operational subordination to the Main Intelligence Directorate (GRU). It is the special forces unit of the Russian Naval Infantry and is composed of highly trained and elite marines within the Naval Infantry. By virtue of belonging to the Russian Naval Infantry, frogmen fall under the Coastal Troops of the Russian Navy service arm. The Russian Navy proper does not field any special forces or special operations units. Russian FSB special forces Alpha Group and Vympel also have frogman units in their respective naval components.
Pinal Airpark, also known as Pinal County Airpark, is a non-towered, county-owned, public-use airport located 8 miles northwest of the central business district of Marana, in Pinal County, Arizona, United States. Silverbell Army Heliport is co-located with Pinal Airpark. The heliport is a private-use military facility operated by the Arizona Army National Guard.
Intermountain Airlines, also known as Intermountain Aviation and Intermountain Airways, was a Central Intelligence Agency (CIA) airline front company. Intermountain performed covert operations for the CIA in Southeast Asia and elsewhere during the Vietnam War era.
The Fulton surface-to-air recovery system (STARS) is a system used by the Central Intelligence Agency (CIA), United States Air Force, and United States Navy for retrieving individuals on the ground using aircraft such as the MC-130E Combat Talon I and B-17 Flying Fortress. It involves using an overall-type harness and a self-inflating balloon with an attached lift line. An MC-130E engages the line with its V-shaped yoke and the person is reeled on board. Red flags on the lift line guide the pilot during daylight recoveries; lights on the lift line are used for night recoveries. Recovery kits were designed for one- and two-man retrievals.
A drifting ice station is a temporary or semi-permanent facility built on an ice floe. During the Cold War the Soviet Union and the United States maintained a number of stations in the Arctic Ocean on floes such as Fletcher's Ice Island for research and espionage, the latter of which were often little more than quickly constructed shacks. Extracting personnel from these stations proved difficult and in the case of the United States, employed early versions of the Fulton surface-to-air recovery system.
Ice Station Zebra is a 1968 American espionage thriller film directed by John Sturges and starring Rock Hudson, Patrick McGoohan, Ernest Borgnine, and Jim Brown. The screenplay is by Alistair MacLean, Douglas Heyes, Harry Julian Fink, and W. R. Burnett, loosely based on MacLean's 1963 novel. Both have parallels to real-life events that took place in 1959. The film concerns a US Nuclear Submarine that must rush to the North Pole to rescue the members of the Ice Station Zebra.
Fletcher's Ice Island or T-3 was an iceberg discovered by U.S. Air Force Colonel Joseph O. Fletcher. Between 1952 and 1978 it was used as a staffed scientific drift station that included huts, a power plant, and a runway for wheeled aircraft. The iceberg was a thick tabular sheet of glacial ice that drifted throughout the central Arctic Ocean in a clockwise direction. First inhabited in 1952 as an arctic weather report station, it was abandoned in 1954 but reinhabited on two subsequent occasions. The station was inhabited mainly by scientists along with a few military crewmen and was resupplied during its existence primarily by military planes operating from Utqiagvik, Alaska. The iceberg was later occupied by the Naval Arctic Research Laboratory, and served as a base of operations for the Navy's arctic research projects such as sea bottom and ocean swell studies, seismographic activities, meteorological studies and other classified projects under the direction of the Department of Defense. Before the era of satellites, the research station on T-3 had been a valuable site for measurements of the atmosphere in the Arctic.
The 5001st Composite Wing is an defunct United States Air Force organization. Throughout its existence, it was assigned to the Alaskan Air Command and stationed at Ladd Air Force Base, Alaska.
William Matthew "Bill" Leary, Jr. was an American academic and aviation historian. For 32 years, Leary taught at the University of Georgia from which he retired as the E. Merton Coulter Professor of History in 2005.
Schatzgräber or “Treasure Hunter” was the name of a military weather station Nazi Germany's Kriegsmarine established in the north of Alexandra Land in the Arctic Franz Josef Land archipelago in 1943. The construction of the secret complex codename “Treasure Hunter” began in 1942 at the command of Adolf Hitler but came into operation only in 1943. The mission of the station's crew started in September that year and lasted until July 1944, when they were summarily evacuated after most of them consumed raw polar bear meat and fell sick.
