Opposed to the Second World War, there was a proliferation of construction yard designs leading up to the Third World War although all continued to provide the same function for the Allies and Soviets. As in the previous war, the construction yard generally completed all components before structure assembly began at the desired site. The only major advancement was that it now possessed two separate construction lines, or queues. The main queue constructed most production buildings, refineries, and support structures, while the armory queue handled base defenses and super-weapons.
