The United States, along with Britain, France and several other nations, committed a coalition force against Gaddafi's forces. On 19 March, the first U.S. action was taken when 114 Tomahawk missiles launched by US and UK warships destroyed shoreline air defenses of the Gaddafi regime. The U.S. continued to play a major role in Operation Unified Protector, the NATO-directed mission that eventually incorporated all of the military coalition's actions in the theater.
