The list of units
"The Queen of the seas," the Battleship has a bombardment range of two and packs a terrific punch both in traditional naval engagements and in offshore bombardment.
A coastal city needs oil in its Strategic Resource box to build a battleship.
The battleship was once the most powerful vessel on the seas. Heavily armored and difficult to destroy, its massive guns could accurately fire heavy projectiles at targets miles away. The battleship had two primary functions: clearing the seas of enemy ships and bombarding enemy coastal targets, usually in preparation for an invasion. The battleship's importance began to decline in World War II when the increasing use of fighters and bombers launched from aircraft carriers greatly extended the range of naval conflicts. Ship-to-ship combat became less frequent than long-range air attacks against enemy battle groups. The last of the U.S. Navy's battleships was decommissioned shortly after the Vietnam War, but the four battleships of the Iowa class were remodeled and re-commissioned in the 1980s.
