Bill overview
This bill, the Making Advancements in Commercial Hypersonics Act (MACH Act), allows NASA to establish a program to support testing of high-speed aircraft and related technologies. NASA will develop a strategic plan for this research, consulting with the Department of Defense and the Federal Aviation Administration. The program is specifically designed to avoid funding the development of hypersonic technologies and restricts agreements with certain foreign entities of concern.
