SAM Missile Battery (Civ3)/Civilopedia

The use of airplanes in warfare began in earnest during World War I. By the end of World War II, the use of fighter 
aircraft and bombers was commonplace and the importance of air warfare continued to grow, as did the importance of 
effective anti-aircraft defenses. During the 1950s, the refinement of rocket technology allowed for the construction 
of compact missiles which were used to deliver explosive warheads to targets swiftly and accurately. Batteries 
of surface-to-air missiles, or SAMs, were built to protect cities and ground installations against airborne attacks. 
The long range and high accuracy of SAM batteries provided a much more effective defense than the anti-aircraft guns 
of World War II.
