高超音速巡航导弹是指巡航速度在5倍音速(5马赫)以上的巡航导弹。这种导弹的速度快、突防能力强、攻击目标范围大,具有极高的军事价值。美国非常重视发展高超音速巡航导弹,国防高级研究计划局(DARPA)、海军、空军都制定了相应的发展计划。DARPA 快速反应导弹演示弹计划 DARPA 的高超音速巡航导弹技术计划于1998年初开始,并与波音公司签订了为期18个月、价值1000万美元的快速反应导弹演示弹(ARRMD)合同,将设计和试验两种高超音速演示弹。对两种演示弹的共同要求是:采用惯性十全球定位系统复合制导,携带113千克的弹头,射程大于640千米,飞行速度大于6马赫,命中精度在9米以内,导弹出厂单价不高于20
Hypersonic cruise missiles are cruise missiles that cruise at 5 times the speed of sound (Mach 5). This kind of missile is fast, capable of penetrating and penetrating, has a large range of attack targets and possesses extremely high military value. The United States attaches great importance to the development of hypersonic cruise missiles, Defense Advanced Research Projects Agency (DARPA), the Navy, Air Force have developed a corresponding development plan. DARPA Rapid Reaction Missile Demonstration Program DARPA's hypersonic cruise missile technology is scheduled to begin in early 1998 and has contracted with Boeing for an 18-month, $ 10 million ARRMD contract to design and test Two hypersonic demonstrations. Common requirements for the two demonstration bombs are: Integrated inertial-10 GPS guidance with 113 kg warhead, range greater than 640 km, flight speed greater than 6 Mach, hit accuracy within 9 m, missile unit price not higher than 20
