Cruise Missiles are long-range, fire-and-forget weapons that can find the target on their own. Like all artillery-type units, Cruise Missiles have no attack or defense values, only bombardment.
A city must have Aluminum in its Strategic Resource box to build Cruise Missiles.
One of the most effective weapons in modern military arsenals is the cruise missile. The AGM-86 and the Tomahawk can be launched against a strategic target hundreds of miles away, traveling low to avoid radar and other means of detection, and hitting their target with unnerving accuracy. They can also be used against short-range, tactical targets such as ships. In this role, it is often possible for a single, one million dollar missile to seriously damage or even destroy 80 million dollar warships.
