AEDC hypervelocity range ‘back in action’
This is the high pressure section of the AEDC Range S-1 that launches hypervelocity projectiles. It is capable of withstanding forces of up to 400,000 pounds per square inch. Though S-1 hasn’t been active in a decade, it is undergoing checkout operations in preparation for future test projects. (U.S. Air Force photo/Deidre Ortiz)
