- The US Air Force is preparing for a second hypersonic ground test having set a record of 13,000 pounds of thrust during recent testing
- The Pentagon is emphasising hypersonics as it prepares for near-peer competition
The US Air Force Research Laboratory (AFRL) is installing an Aerojet Rocketdyne-designed air-breathing hypersonic engine as it prepares for a second test.
AFRL recently set a record for the highest thrust produced by an air-breathing hypersonic engine in US Air Force (USAF) history. AFRL achieved over 13,000 pounds of thrust from a scramjet engine during testing at Arnold Air Force Base, Tennessee. The 5.5 m-long Northrop Grumman engine endured 30 minutes of accumulated combustion time during the nine months of testing, according to a service statement.
