Recently NASA has completed an independent technical evaluation of the Bradford Reaction Wheel Unit (RWU) product as a potential alternative to the existing offerings from US-domestic reaction wheel suppliers.

The assessment covers all NASA programs planning to use reaction wheels as spacecraft attitude control actuators, and concludes that the Bradford reaction wheel product line appears to be an attractive, foreign manufactured, alternative for consideration on some of NASA future missions.

It is a reasonable option for NASA spaceflight programs to carefully evaluate the Bradford reaction wheel for their specific mission-unique spacecraft ACS application. Depending on the specific lifetime and performance requirements, the Bradford wheel could be a viable candidate for consideration by a NASA program, project, or mission.
