The THOR-ER program team, a collaborative effort between the United States and Norway to develop a solid fuel ramjet (SFRJ) vehicle, achieved an important milestone on August 17 at Andøya in northern Norway. The test vehicle successfully fired several times, showing the viability of ramjet propulsion technology and demonstrating significant increases in effective range.
“The United States needs to be working closely with our allies to ensure our joint force has the most cutting-edge capabilities on the battlefield,” said Heidi Shyu, Under Secretary of Defense for Research and Engineering. “I commend the THOR-ER team on their outstanding work weathering the pandemic environment, continuing the development of this significant propulsion technology, and promoting continued science and technology collaboration with our partners in Norway.”
