USAF Titan II ICBM Complex

​Fluor was selected by the U.S. Air Force to build the Titan II Intercontinental Ballistic Missile (ICBM) complex near Tucson, Arizona. Fluor played a major role in the construction of this retaliatory defense system, providing design services and serving as prime construction contractor.

Client's Challenge

As Cold War tensions mounted, the U.S. Air Force and Army Corps of Engineers directed the construction of the Titan II ICBM complex. The project was a critical mission for the U.S. government in the Cold War environment.

Fluor's Solution

To expedite startup of the Titan II system, construction and missile site activation were accomplished in phases, beginning with earthwork and the heavy steel and concrete construction of the basic control center, blast lock, cable way and silo structures.

Next, the interior steel support and shock-resistant structures, along with mechanical, electrical, heating and air conditioning were completed, followed by the control systems that interfaced for missile activation. This phase also included the fabrication and installation of the silo closure doors and the checkout and testing of the installed systems.

As the prime construction contractor for these phases, Fluor contended with a construction schedule impacted by a massive number of design changes and by the Cuban Missile Crisis. 

Each site consisted of a silo, tunnel and control center deep underground. Fluor oversaw construction of most of the ground support equipment, structural steel and piping at each complex. Each silo was fitted with a seventeen-inch-thick concrete tube, or launch duct. The Titan II was housed inside this steel-clad duct. A five-foot-thick concrete and steel door covered each silo. 

Fluor utilized a decentralized project office which was fully responsible for all detail engineering, office and financial functions, purchasing, scheduling, safety, labor relations and construction management. Its project organization essentially paralleled that of the Corps of Engineers to enhance coordination, communications and efficiency in project execution. Fluor implemented a strong safety program that was followed by all trade unions and employers working on site.


Understanding the national security implications of the project, Fluor delivered the 18-site Titan II ICBM complex on schedule to the U.S​. government despite abundant change orders and design modifications.
