Operation Odyssey Dawn was the U.S. code name for the American role in the international military operation in Libya to enforce United Nations Security Council Resolution 1973 during the initial period of 19–31 March 2011, which continued afterwards under NATO command as Operation Unified Protector. The initial operation implemented a no-fly zone that was proposed during the Libyan Civil War to prevent government forces loyal to Muammar Gaddafi from carrying out air attacks on anti-Gaddafi forces.

Operations commenced on the same day with a strike by French fighter jets, then US and UK forces conducting strikes from ships and submarines via 110 Tomahawk cruise missiles and air assets bombin
