a beginning
A Beginning

Use of the V-2 in World War II showed rockets had military applications

US use of a nuclear weapon to end the war in the Pacific heightened mistrust between Russia and the West

Postwar recruitment of German scientists by both the West and Russia advanced early rocket programs

early visions of space operations
Early Visions of Space Operations

RAND corporation published Preliminary Design of an Experimental World-circling Spaceship

Soviets’ test of first hydrogen bomb and suspected development of missile delivery systems heightened drive for early-warning and tracking systems

the gaither commission
The Gaither Commission

Commission appointed by President Eisenhower to assess civil defense posture following a nuclear attack

Commission also assessed whether a US counter strike was possible

Showed counterstrike unlikely due to inability to predict attack until first warhead fell

Accelerated US ICBM development and other strategic programs

the first space tracking stations
The First Space Tracking Stations

Minitrack

Built by the Naval Research Laboratory

Network of simple ground tracking stations developed to track a proposed new satellite under the Vanguard Program

Moonwatch

Smithsonian Institution developed a network of Baker-Nunn Cameras

Sought civilian volunteers to phone in when they saw the satellite

the first satellite
The First Satellite

Launch of Sputnik shocked the US and highlighted Minitrack’s inability to accurately track Sputnik

Sputnik tracking mainly from Moonwatch teams

Department of Defense’s Advanced Research Projects Agency (ARPA) established Project Shepherd as an effort to improve Minitrack’s tracking problems

from air to aerospace
From “Air” to “Aerospace”

1959 change to the Air Force mission added the word “aerospace” to recognize space’s new importance

ARPA opened a system program office to develop equipment and techniques to track space objects and incoming Soviet missiles

By the mid 1960s, had three radar sites that could give 15-minute warning of missile impact

Radar sites also tracked space objects

norad begins
NORAD Begins

North American Air Defense Command (NORAD) established in Sep 1957

Joint effort with Canada

Mission to defend combined airspace of US and Canada

Development of submarine-launched ballistic missiles (SLBMs) by US and Soviets created a need for more tracking stations

Air Force developed several radars on the Atlantic, Pacific and Gulf Coasts

Entire system operational by 1972

air force developments
Air Force Developments

SLBM warning augmented by Air Force’s new space-tracking radar in Florida

Air Force brought more tracking ability by developing PAVE PAWS radar sites

Powerful phased-array radar—steerable beam

Sites established in Massachusetts, California, Georgia, and Texas

anti ballistic missile programs
Anti-ballistic Missile Programs

DoD attempted to establish a defense shield against Soviet missile attack

Covered one area of US: ICBM sites in North Dakota to enable US counter strike if attacked

Shut down by congress in 1976 due to great expense and low probability of success

Air Force took over the system’s radars to

Aid early warning for SLBMs over Hudson Bay

Add coverage for ICBM early warning

Improve accurate space tracking

strategic air command s era
Strategic Air Command’s Era

Strategic Air Command (SAC) took over administrative control of people and equipment in space surveillance and missile-warning missions

NORAD maintained operational control over these missions

Several studies in the 1970s suggested the need for reorganization

a new command is born
A New Command is Born

Space Command began in 1982 under General James V. Hartinger

SAC passed operational control of at least 25 space-surveillance and missile-warning sensors to Space Command

Air Force Systems Command controlled much of the Air Force’s launch systems and satellites
