The United States successfully used a ship-fired missile to intercept an Intercontinental Ballistic Missile, or ICBM, in a first-of-its-kind test, according to the Missile Defense Agency.

The test involved launching an ICBM from Kwajalein Atoll in the Marshall Islands, located in the Pacific Ocean, thousands of miles from Hawaii and the West Coast of the continental U.S. on Monday night local time. The destroyer in position, USS John Finn, fired a Standard Missile-3 Block IIA which successfully intercepted the target.
