The United States Armed Forces are the military forces of the United States. The armed forces consist of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. All six armed services are among the eight uniformed services of the United States.
North American Aerospace Defense Command, known until March 1981 as the North American Air Defense Command, is a combined organization of the United States and Canada that provides aerospace warning, air sovereignty, and protection for Canada and the continental United States.
The United States Space Command is a unified combatant command of the United States Department of Defense, responsible for military operations in outer space, specifically all operations 100 kilometers and greater above mean sea level. U.S. Space Command is responsible for the operational employment of space forces that are provided by the uniformed services of the Department of Defense.
The Air Force Research Laboratory (AFRL) is a scientific research and development detachment of the United States Air Force Materiel Command dedicated to leading the discovery, development, and integration of direct-energy based aerospace warfighting technologies, planning and executing the Air Force science and technology program, and providing warfighting capabilities to United States air, space, and cyberspace forces. It controls the entire Air Force science and technology research budget which was $2.4 billion in 2006.
The Defense Support Program (DSP) is a program of the United States Space Force that operated the reconnaissance satellites which form the principal component of the Satellite Early Warning System used by the United States.
The United States Army Space and Missile Defense Command (USASMDC) is the Army Service Component Command (ASCC) for United States Strategic Command and United States Space Command. It was established in 1985 as the Army Strategic Defense Command, responsible for ballistic missile defense. In 1992, it merged with Army Space Command to become Army Space and Strategic Defense Command. In 1997, it became an Army Major Command and was redesignated Army Space and Missile Defense Command.
Patrick Space Force Base is a United States Space Force installation located between Satellite Beach and Cocoa Beach, in Brevard County, Florida, United States. It is named in honor of Major General Mason Patrick, USAAC. It is home to Space Launch Delta 45, known as the 45th Space Wing (45 SW) when it was part of the Air Force. In addition to its "host wing" responsibilities at Patrick SFB, the 45 SW controls and operates Cape Canaveral Space Force Station (CCSFS) and the Eastern Range. It was originally opened and operated from 1940 to 1947 as Naval Air Station Banana River, a U.S. Navy airfield. It was then deactivated as a naval installation in 1947 and placed in caretaker status until it was transferred to the Air Force in late 1948.
The militarisation of space involves the placement and development of weaponry and military technology in outer space. The early exploration of space in the mid-20th century had, in part, a military motivation, as the United States and the Soviet Union used it as an opportunity to demonstrate ballistic-missile technology and other technologies having the potential for military application. Outer space has since been used as an operating location for military spacecraft such as imaging and communications satellites, and some ballistic missiles pass through outer space during their flight. As of 2018, known deployments of weapons stationed in space include only the Almaz space-station armament and pistols such as the TP-82 Cosmonaut survival pistol.
A space command is a military organization with responsibility for space operations and warfare. A space command is typically a joint organization or organized within a larger military branch and is distinct from a fully independent space force. The world's first space command, the United States' Air Force Space Command was established in 1982 and later became the United States Space Force in 2019.
The Islamic Revolutionary Guard Corps Aerospace Force, officially known as the Islamic Revolutionary Guard Corps Air and Space Force, is the strategic missile, air, and space force of the Islamic Revolutionary Guard Corps (IRGC). It was renamed from the IRGC Air Force to the IRGC Aerospace Force in 2009.
Space Systems Command (SSC) is the United States Space Force's space development, acquisition, launch, and logistics field command. It is headquartered at Los Angeles Air Force Base, California, and manages the United States' space launch ranges.
Space Launch Delta 30 is a United States Space Force space launch delta assigned to Space Systems Command and headquartered at Vandenberg Space Force Base, California. The Space Launch Delta 30 is responsible for all space launch operations from the west coast, which includes all polar launches. It manages the Western Range and launch activities for the Space Force, Department of Defense, NASA, and other private space corporations. The Space Launch Delta 30 also supports test and evaluation launches of the U.S. Air Force's intercontinental ballistic missile force.
The Space Launch Delta 45 is a unit of the United States Space Force. The Space Launch Delta 45 is assigned to Space Systems Command and headquartered at Patrick Space Force Base, Florida. The wing also controls Cape Canaveral Space Force Station. The 45th Space Delta is responsible for all space launch operations from the East Coast. It manages the Eastern Range, including launch activities for the Space Force, Department of Defense (DoD), NASA, and other private space corporations.
The 10th Aerospace Defense Group was inactivated on 31 December 1970 by the United States Air Force (USAF). Its last assignment was with Fourteenth Aerospace Force at Vandenberg Air Force Base, California. The 10th Aerospace Defense Group and Squadron were the sole operators of the United States' second nuclear-tipped anti-satellite weapon, Weapons System 437 (WS-437). For this reason the squadron continues the group history through temporary bestowal.
A space force is a military branch of a nation's armed forces that conducts military operations in outer space and space warfare. The world's first space force was the Russian Space Forces, established in 1992 as an independent military service. However, it lost its independence twice, first being absorbed into the Strategic Rocket Forces from 1997–2001 and 2001–2011, then it merged with the Russian Air Force to form the Russian Aerospace Forces in 2015, where it now exists as a sub-branch. As of 2024 the world's only independent space force is the United States Space Force.
The Russian Aerospace Forces or Russian Air and Space Forces comprise the air and space branches of the Armed Forces of the Russian Federation. Russia established the VKS as a new branch of its military on 1 August 2015 with the merging of the Russian Air Force (VVS) and the Russian Aerospace Defence Forces (VVKO), as recommended by the Ministry of Defence. The VKS has its headquarters in Moscow. Russia's Defense Minister Sergei Shoigu explained the merger as improving efficiency and logistical support.
The United States Space Force (USSF) is the space service branch of the United States Armed Forces. Along with the Air Force, it is part of the Department of the Air Force, led by the secretary of the Air Force. Its military heads are the chief of space operations, who is one of the Joint Chiefs of Staff, and the vice chief of space operations.
Space Operations Command (SpOC) is the United States Space Force's space operations, cyber operations, and intelligence field command. Headquartered at Peterson Space Force Base, Colorado, it consists of its mission deltas, and garrison commands.
The United States Space Force is organized by different units: the Space Staff, the field commands, and the space deltas.
While the United States Space Force gained its independence on 20 December 2019, the history of the United States Space Force can be traced back to the beginnings of the military space program following the conclusion of the Second World War in 1945. Early military space development was begun within the United States Army Air Forces by General Henry H. Arnold, who identified space as a crucial military arena decades before the first spaceflight. Gaining its independence from the Army on 18 September 1947, the United States Air Force began development of military space and ballistic missile programs, while also competing with the United States Army and United States Navy for the space mission.
