“联合空面火力圈外导弹”(JASSM)的竞争将随选定赢得合同的承包商,于1998年4月初结束。这种隐身的侧面倾斜的导弹具有两个相同的可互换的小展弦比弹翼和四个尾翼。全部六个控制面都可以各种组合的方式折叠,以便挂载在许多不同飞机上,包括挂载在B-2和F-117的内部。而且,导弹的平的底部提供一个大升力面,导弹有倾斜能力,使它能比其他导弹更迅速地转弯。 波音的JASSM巡航导弹方案从其80年代后期的“HaveSlick”保形武器项目发展而来。其设计思想是把导弹设计成可贴隐身飞机的蒙皮挂载,而不显著增加其雷达反射性。保形挂载仍然相当重要,因为对隐身飞机要考虑的一个主要问题是需要在内部弹舱内挂载所有武器,故其火力 The competition for JALM will be completed in early April 1998 with the contractor who has chosen to win the contract. This stealthy, side-slanted missile has two identical small aspect ratio flaps and four tail flaps. All six control surfaces are collapsible in various combinations for mounting on many different aircraft, including the B-2 and F-117. Moreover, the flat bottom of the missile provides a large lift surface, and the missile is tilted to make it turn more rapidly than other missiles. The Boeing JASSM cruise missile program evolved from its HaveSlick conformal weapon program of the late 1980s. Its design idea is that the missile is designed to be mounted on the skin of an invisible aircraft without significantly increasing its radar reflectivity. Conformal mountings are still important, as one of the major issues to be considered for stealth aircraft is the need to mount all the weapons in the internal bomb bay, so their firepower
