US Hypersonic Cruise Missiles

摘要

The US Air Force and Navy are beginning to examine hypersonic cruise missiles to attack surface targets.rnThe Navy has supported a string of such programs such as Fasthawk (also known as Low Cost Missile System/LCMS) in 1996, High Speed Strike Missile (HiSSM) in 1997. In a related move, in 1998 DARPA began a program called ARRMD (Affordable Rapid Response Missile Demonstrator) which examined air-launched hypersonic cruise missile propulsion. ARRMD resulted in a dual-combustor ramjet (DCR) design that underwent lab trials in the summer of 2001. DARPA is now funding the program as HyFly (Hypersonic Flight) program. The Boeing HyFlyrnmissile with Aerojet propulsion had an initial test in 2006, with full-power tests scheduled to begin in 2007. The Navy's Office of Naval Research has been promoting a variety of applications for hypersonic missiles such as the Lockheed Martin RATTLR (Revolutionary Approach to Time Critical Long Range Strike Project).rnThe Air Force supported a NASA effort in hypersonic flight, the X-43 demonstrator and the third test flight in 2004 reached speeds close to Mach 10. The Air Force is currently planning a spin-off scram-jet demonstrator program called the endothermically fueled scramjet engine flight demonstrator (EFSEFD), also known as X-51 Waverider as well as hypersonic long-range missilerndesigns such as the Lockheed Martin Falcon (Force Application and Launch from CONUS).
