Propelled by liquid oxygen and kerosene, the basic rocket was 65 feet (19.8 meters) in length, had a body diameter of 8 feet (2.4 meters), and weighed 110,000 pounds (49,900 kilograms) at firing.
The Thor was declared operational by 1959 and was assigned to the Strategic Air Command and also deployed to England where the Royal Air Force maintained them in a state of combat-readiness.
The Thor was used either as a single-stage booster or in combination with various types of upper stages for such projects as Tiros, Telstar, Pioneer, and Discoverer.

The Thor program unfolded with amazing speed, and within 3 years of the program’s inception the first Thor squadron became operational in the U.K. The Thor was a stop-gap measure, however, and once the first generation of ICBMs based in the United States became operational, the Thor missiles were quickly retired.
The engine was developed as a direct descendant of the Atlas booster engine.
Early Thor engines suffered from what was known as "Bearing Walking', whereby the turbopump bearings rotate axially within their housing, causing it to wear out and the bearings to seize.

Using existing components (the Rocketdyne S-3D liquid-fuel rocket motor from the Army's SM-78/PGM-19 Jupiter IRBM, and the inertial guidance unit and Mk.2 reentry vehicle from the SM-65D/CGM-16D Atlas), and requiring the missile to be air-transportable by C-124 Globemaster transport aircraft, the basic design and overall dimensions of the Thor were quickly determined.
During 1962, the Thor was used in a series of exo-atmospheric nuclear tests (called "Starfish", "Bluegill", and "Kingfish"), including the explosion of a 1.4 MT device at an altitude of 450 km (280 miles).
Unarmed tests of Thors as ASAT missiles began in February 1964, and by September 1964 the ASAT Thor was declared operational.
