The USAF has awarded Raytheon a $27.99 million contract modification in connection with the Phase I Preliminary Design Review (PDR) in the Southern Cross Integrated Flight Research Experiment (SCIFiRE) long-range hypersonic missile programme.
In completing the PDR by 2 September 2022 at Tuscon, Arizona, Raytheon will ‘mature a solid rocket-boosted, air-breathing, hypersonic conventional cruise missile, air-launched from existing fighter/bomber aircraft’, the DoD noted on 3 September.
SCIFiRE is a collaborative effort between Australia and the US, with the two governments signing a deal in November 2020 to develop and test full-sized hypersonic cruise missile prototypes.
In particular, the R&D programme is intended to result in a precision strike missile capable of travelling at Mach 5.
At the time, Shephard noted that Australia and the US have been collaborating on R&D relating to hypersonic scramjets, rocket motors, sensors and advanced manufacturing materials for more than 15 years.
