Bold Orion
Encyclopedia
The Bold Orion missile, also known as Weapons System 199B (WS-199B), was a prototype air-launched ballistic missile
Air-launched ballistic missile
An air-launched ballistic missile or ALBM is a ballistic missile launched from an aircraft. This class of missile never saw active use. The only known missile of this type that was intended for operational service, the GAM-87 Skybolt, intended to be launched from B-52 Stratofortress and Avro...

 designs, the missile was moderately successful in testing, and helped pave the way for development of the GAM-87 Skybolt ALBM. In addition, the Bold Orion was used in early anti-satellite weapons testing, performing the first interception of a satellite by a missile.

, not to deliver operational weapons; a primary emphasis was on proving the feasibility of an air-launched ballistic missile.

The designation WS-199B was assigned to the project that, under a contract awarded in 1958 to Martin Aircraft, would become the Bold Orion missile. The design of Bold Orion was simple, utilizing parts developed for other missile systems to reduce the cost and development time of the project.

Operational history

Having been given top priority by the Air Force, the first flight test of the Bold Orion missile was conducted on May 26, 1958, from a Boeing B-47 Stratojet carrier aircraft, which launched the Bold Orion vehicle at the apex of a high-speed, high-angle climb. The zoom climb

 from the rocket motor of the missile itself, allowed the missile to achieve its maximum range, or, alternatively, to reach space.

A twelve-flight test series of the Bold Orion vehicle was conducted; however, despite suffering only one outright failure, the initial flight tests of the single-stage rocket proved less successful than hoped. Authorisation was received to modify the Bold Orion to become a two-stage vehicle; in addition to the modifications improving the missile's reliability, they increased the range of Bold Orion to over 1000 miles (1,609.3 km). Four of the final six test firings were of the two-stage vehicle; these were considered completely successful, and established that the ALBM was a viable weapon.

ASAT test

The final test launch of Bold Orion, conducted on October 13, 1959, was a test of the vehicle's capabilities in the anti-satellite role. Launched from an altitude of 35000 feet (10,668 m) from its B-47 mothership, the missile successfully intercepted the Explorer 6

 satellite, passing its target at a range of less than 4 miles (6.4 km) at an altitude of 156 miles (251.1 km). Had the missile been fitted with a nuclear warhead, the satellite would have been destroyed.

The Bold Orion ASAT test was the first interception of a satellite by any method, proving that anti-satellite missiles were feasible. However this test, along with an earlier, unsuccessful test of the High Virgo

 missile in the anti-satellite role, had political repercussions; the Eisenhower administration sought to establish space as a neutral ground for everyone's usage, and the "indication of hostile intent" the tests were seen to give was frowned upon, with anti-satellite weapons development being curtailed shortly thereafter.

Legacy

The results of the Bold Orion project, along with those from the testing of the High Virgo missile, also developed under WS-199, provided data and knowledge that assisted the Air Force in forming the requirements for the follow-on WS-138A, which would produce the GAM-87 Skybolt missile.
