ArcLight (missile)
The ArcLight program was a missile development program of the Defense Advanced Research Projects Agency with the goal of equipping ships like Aegis cruisers with a weapon system capable of striking targets nearly anywhere on the globe, thereby increasing the power of surface ships to a level comparable to that of ballistic missile-equipped submarines. According to DARPA, the ArcLight program was to develop a high-tech missile based on the booster stack of the current SM-3 and equipped with a hypersonic glide vehicle capable of carrying a 100–200 lb (45–90 kg) warhead.
