截止1973年6月30日,4颗在轨DSP卫星共计发现了1014次导弹发射的秘密。这些卫星成功地完成了使命,通过利用卫星显著地减少这种极具威胁性的导弹攻击,从而缓和了在冷战期间一直存在的某种紧张气氛。但这些卫星也存在一些问题。本文详述了解决这些问题所采取的措施,以及如何保持今后10年中导弹早期预警系统的作战能力。 As of June 30, 1973, a total of 1014 missiles fired by four orbit DSP satellites were discovered. These satellites have successfully completed their mission to ease some of the tensions that have persisted during the Cold War by using satellites to significantly reduce this highly threatening missile attack. However, there are some problems with these satellites. This article details the steps taken to address these issues and how to maintain the operational capabilities of the early warning system for missiles over the next 10 years.
