The M5 Hornet Interceptor Missile, also known as the Hornet Missile, M5 Interceptor Missile, and officially the Model-5 Counter-Ballistic, Computer-Guided, Hornet Tactical Self-Propelled Ordinance, was a type of United Nations Space Command Naval counter-ballistic ordinance used most commonly by capital-grade spacefaring combat vessels, lighter escort-grade warships, and to a lesser extent by semi-mobile and/or stationary orbital complexes; testing has also been performed for atmospheric operations with the M5 Hornet, though results were at or below satisfactory in most situations.
