Question: Operation Odyssey Dawn involved what long-range, all-weather, subsonic cruise missile?

 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. 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.  On 19 March 2011, several countries prepared to take immediate military action at a summit in Paris.  Operations commenced on the same day with a strike by French fighter jets, then U.S. and UK forces conducting strikes from ships and submarines via 110 Tomahawk cruise missiles and air assets bombing Gaddafi forces near Benghazi.  The goal of coalition forces was to impose a no-fly zone for Libyan government forces. <SEP> On 19 March 2011, a multi-state NATO-led coalition began a military intervention in Libya, ostensibly to implement United Nations Security Council Resolution 1973.  The United Nations Intent and Voting was to have "an immediate ceasefire in Libya, including an end to the current attacks against civilians, which it said might constitute crimes against humanity" ... "imposing a ban on all flights in the country's airspace – a no-fly zone – and tightened sanctions on the Qadhafi regime and its supporters."  The resolution was taken in response to events during the Libyan Civil War, and military operations began, with American and British naval forces firing over 110 Tomahawk cruise missiles, the French Air Force, British Royal Air Force, and Royal Canadian Air Force undertaking sorties across Libya and a naval blockade by Coalition forces.  French jets launched air strikes against Libyan Army tanks and vehicles.  The Libyan government response to the campaign was totally ineffectual, with Gaddafi's forces not managing to shoot down a single NATO plane despite the country possessing 30 heavy SAM batteries, 17 medium SAM batteries, 55 light SAM batteries (a total of 400–450 launchers, including 130–150 2K12 Kub launchers and some 9K33 Osa launchers), and 440–600 short-ranged air-defense guns.  The official names for the interventions by the coalition members are Opération Harmattan by France; Operation Ellamy by the United Kingdom; Operation Mobile for the Canadian participation and Operation Odyssey Dawn for the United States. <SEP> The AGM-84E Standoff Land Attack Missile (SLAM) was a subsonic, over-the-horizon air-launched cruise missile that was developed by Boeing Integrated Defense Systems from the McDonnell Douglas Harpoon antiship missile.  The SLAM was designed to provide all-weather, day and night, precision attack capabilities against stationary high-value targets. <SEP>  Introduced by General Dynamics in the 1970s, it was initially designed as a medium to long-range, low-altitude missile that could be launched from a surface platform.  Since then, it has been upgraded several times with guidance systems for precision navigation.  From 1992-1994, McDonnell Douglas Corporation was the sole supplier of Tomahawk Missiles and produced Block II and Block III Tomahawk missiles and remanufactured many Tomahawks to Block III specifications.  In 1994, Hughes outbid McDonnell Douglas Aerospace to became the sole supplier of Tomahawk missiles.  It is now manufactured by Raytheon. The Tomahawk ( or ) Land Attack Missile (TLAM) is a long-range, all-weather, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ship and submarine-based land-attack operations.  In 2016, the U.S. Department of Defense purchased 149 Tomahawk Block IV missiles for $202.3 million.
