英国宇航公司动力分部为研制一种符合北约来年军事要求的空中发射型巡航导弹而主动向英国国防部提交了一个计划。该导弹将使用目前正在研究中的空中发射的反舰导弹“海鹰”的弹体结构。为把射程增加到“战略武器限制条约”(SALT)所规定的600公里(372海里)的范围内,必须增加燃料容量,并将使用像“海鹰”那样的微型涡轮喷气发动机。 British Aerospace Power Division voluntarily submitted a plan to the Department of Defense for the development of a type of air-launched cruise missile that meets NATO’s military requirements for the coming year. The missile will use the missile structure of the Seahawk, an anti-ship missile currently being studied in the air. To increase its range to a range of 600 km (372 nm) as defined by the SALT, it is necessary to increase fuel capacity and to use micro-turbojet engines like the Seahawks.
