### Project 066 — Joint Hypersonic Transition Office (JHTO)

This program supports the Department's initiatives to Build Sustainable and Long-Term Advantage and Build a Resilient Joint Force and Defense Ecosystem. The Joint Hypersonics Transition Office (JHTO), within the Office of the Assistant Secretary of War for Science and Technology (ASW(S&T)), was created to establish a university consortium for hypersonics research; support workforce development; expedite testing, evaluation, and acquisition of hypersonic technologies to meet the stated needs of the warfighter; ensure that prototyping demonstration programs on hypersonic systems integrate advanced technologies to speed the maturation and deployment of future hypersonic systems; develop strategies, roadmaps, and technology protection measures for hypersonics to enable the transition of such technologies to future operational capabilities for the warfighter; and develop and implement a strategy for enhancing the current and future hypersonics workforce.
