Movement and Maneuver in Deep Space: A Framework to Leverage Advanced Propulsion is Wright Flyer Paper No. 67, published by Air University Press in May 2019. Its authors are three U.S. Air Force majors, Brian E. Hans, Christopher D. Jefferson and Joshua M. Wehrle, writing for Air University's Space Horizons research group. The testimony dates the work to 2017.[1][2]
The paper
The 64-page paper sets out capability requirements, possible solutions and a strategic rationale for gaining an advantage in movement and manoeuvre in deep space, arguing that such capabilities would bring wide benefits to national security. According to the testimony, it discusses how emerging propulsion concepts — including speculative ones such as the Mach-effect thruster and the EmDrive — might change military operations in space if they proved to work, while noting that some remained controversial and unproven.[1][2]
Speculative propulsion
The Mach-effect thruster, proposed by physicist James Woodward, uses piezoelectric stacks to produce claimed transient mass fluctuations; the testimony points out that related piezoelectric experiments, some involving a Lockheed engineer, had been done at the unclassified level about twenty years earlier. The EmDrive, a closed microwave cavity claimed to produce thrust without propellant, was tested by Martin Tajmar's group at the Technical University of Dresden, which concluded in 2021 that apparent thrust readings were caused by experimental errors.[3]
Significance
The paper is a doctrine study, not a report of working technology. UFO researchers cite it as evidence that the Air Force was taking speculative propulsion seriously at the time the UAP subject returned to public attention.[1][3]
