The XPWN-9A Kangaroo was a project to develop a sounding rocket intended for use by the United States Navy. Using an unconventional design, flight tests were unsuccessful, and it was not put into production.

History

[edit]

The Kangaroo was designed as a "boosted dart" type rocket, the unpropelled "dart" containing the payload being housed within the solid booster rocket's propellant, where, upon burnout, it would be ejected from the rocket by a pyrotechnic device.[1] Rail launched, Kangaroo was intended to be used to measure radiation levels and the density of micrometeorites prior to the launch of crewed space flights.[2]

The initial design of what was then called Kangaroo-Dart was developed by the Aeromachnics Branch of the U.S. Navy's Pacific Missile Range.[1] Detailed design was performed by Aerojet;[3] however when bids for developing the prototype, given the designation XPWN-9A, were requested, United Technologies Corporation submitted the winning bid and was given a contract for construction of prototypes in November 1969.[3]

Flight trials of the Kangaroo booster were undertaken at the Pacific Missile Range at Point Mugu; they proved unsuccessful, and production of the rocket was not undertaken.[3]
