#军事新闻# 从DDG-51一直到DDG-124，阿利伯克级驱逐舰icon装备的都是AN/SPY-1相控阵雷达，直到2021年6月下水的DDG-125"杰克·卢卡斯”开始，使用AN/APY-6相控阵雷达。那么之间的型号去哪了？DDG-1000朱姆沃尔特驱逐舰，原本准备装备工作在X波段的AN/SPY-3有源相控雷达和工作在S波段的AN/SPY-4立体搜索雷达，DDG-1000icon也是第一个双波段相控阵雷达的战舰。不仅如此，DDG-1000的双波段雷达，每一个都可以工作在两个不同的频段，当一个雷达负荷较重时，另一个雷达可以帮助它分担工作。但是，不幸的是，出于缩减成本的考虑，2009年，DDG-1000的S波段搜索雷达AN/SPY-4被取消，因此DDG-1000便只剩下了AN/SPY-3一个雷达。虽然，AN/SPY-3是一个可以工作在S、X两个波段的有源相控阵雷达，但是不能同时工作在S、X波段，所以，它已经不能算是双波段雷达了。失去了整整一代的美国驱逐舰，因此从AN/SPY-1D直接过渡到了AN/SPY-6。
