Kongsberg Penguin missile
The Penguin missile, made by the Norwegian firm, Kongsberg, was the first anti-shipping missile of any NATO county. Its manufacturer designates the major versions as "Marks" and versions within Marks as Mods, much as the U.S. Navy designates its guns and torpedoes. In U.S. service, the missile is known as the AGM-119 Penguin.
The missiles can be launched from land, ships, and aircraft; the U.S. version is launched by ship-based helicopters.
