TheBold Orionmissile, also known asWeapons System 199B(WS-199B), was a prototypeair-launched ballistic missile(ALBM) developed byMartin Aircraftduring the 1950s. Developed in both one- and two-stagedesigns, the missile was moderately successful in testing, and helped pave the way for development of theGAM-87 SkyboltALBM. In addition, the Bold Orion was used in earlyanti-satellite weaponstesting, performing the first interception of a satellite by a missile.

Design and development

edit

The Bold Orion missile was developed as part ofWeapons System 199,initiated by theUnited States Air Force(USAF) in response to the U.S. Navy'sPolarisprogram,[1]with funding authorised by theUnited States Congressin 1957.[2]The purpose of WS-199 was the development of technology that would be used in new strategic weapons for the USAF'sStrategic Air Command,not to deliver operational weapons; a primary emphasis was on proving the feasibility of an air-launched ballistic missile.[2][3][4]

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.[3]The design of Bold Orion was simple, using parts developed for other missile systems to reduce the cost and development time of the project.[3]The initial Bold Orion configuration was a single-stage vehicle, using aThiokolTX-20 Sergeant solid-fuel rocket.[3][5]Following initial testing, the Bold Orion configuration was altered to become a two-stage vehicle, anAllegany Ballistics LaboratoryAltairupper stage being added to the missile.[3][6]

Operational history

edit

Having been given top priority by the Air Force,[7]the first flight test of the Bold Orion missile was conducted on May 26, 1958, from aBoeing B-47 Stratojetcarrier aircraft,[3][8]which launched the Bold Orion vehicle at the apex of a high-speed, high-angle climb.[3][9]Thezoom climbtactic, combined with thethrustfrom the rocket motor of the missile itself, allowed the missile to achieve its maximum range, or, alternatively, to reach space.[9]

A twelve-flight test series of the Bold Orion vehicle was conducted;.[3]Despite suffering only one outright failure, the initial flight tests of the single-stage rocket proved less successful than hoped.[3]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 1,000 miles (1,600 km).[4][10]Four of the final six test firings were of the two-stage vehicle. These were considered successful, and established that the ALBM was a viable weapon.[2][3]

ASAT test

edit

The final test launch of Bold Orion, conducted on October 13, 1959, was a test of the vehicle's capabilities in theanti-satelliterole.[11][12]Piloted by Carl E Brust Jr, the missile was launched from an altitude of 35,000 feet (11,000 m) from its B-47 mothership, the missile successfully intercepted theExplorer 6satellite,[13]passing its target at a range of less than 4 miles (6.4 km) at an altitude of 156 miles (251 km).[14][3]If the missile had a nuclear warhead, the satellite would have been destroyed.[9][15]

The Bold Orion ASAT test was the first interception of a satellite by any method, proving that anti-satellite missiles were feasible.[11][16]This test, along with an earlier, unsuccessful test of theHigh Virgomissile in the anti-satellite role, had political repercussions. TheEisenhower administrationsought to establish space as a neutral ground for everyone's use, and the "indication of hostile intent" given by the tests was frowned upon, with anti-satellite weapons development being soon curtailed.[9][17]

Legacy

edit

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 theGAM-87 Skyboltmissile.[3][18]
