The Hypersonic Air Launched Offensive Anti-Surface (HALO) was a hypersonic air-launched anti-ship missile being developed for the United States Navy. It was designed to provide greater anti-surface warfare capability than the AGM-158C LRASM and was expected to be compatible with F/A-18E/F Super Hornet. The initial operational capability was expected in 2028. The program was also called the Offensive Anti-Surface Warfare Increment 2 program.
