美軍福特號未來最強武器，HALO高超音速反艦導彈，LRASM的延續型號，使用超燃衝壓發動機，速度至少5馬赫，射程1000公里以上，全程動力可控，綜合實力超越鋯石導彈|美海軍|巡航導彈|

目前，美軍正同步開展4個高超音速武器專案，分別是“空射快速回應武器（ARRW）”“高超音速吸氣式武器概念（HAWC）”“遠程高超音速武器（LRHW）”和“中程常規快速打擊武器系統（IRCPS）”。這些專案各具特點。美海軍在2023財年預算申請中，將2022財年首次披露的“進攻性反水面作戰武器增量2”（OASuW Inc 2）正式更名為“高超聲速空射OASuW”（HALO），謀求快速採辦一型用於航母艦載戰鬥機的新型高超聲速巡航導彈。據悉，HALO導彈最高速度超越5馬赫，預計2028財年投入使用。HALO應是一款具備低空突防能力的遠程高超音速空射型反艦導彈。In the budget application for fiscal year 2023, the U.S. Navy formally renamed the "Offensive Anti-Surface Warfare Weapon Increment 2" (OASuW Inc 2) disclosed for the first time in fiscal year 2022 to "Hypersonic Air-Launched OASuW" (HALO) in order to seek rapid acquisition. A new type of hypersonic cruise missile for carrier-based fighters. It is reported that the maximum speed of the HALO missile exceeds Mach 5 and is expected to be put into use in fiscal year 2028. HALO should be a long-range hypersonic air-launched anti-ship missile with low-altitude penetration capabilities.
