Environmental Impact Statement MX: Buried Trench Construction and Test Project
The Air Force proposes to construct two sections of underground tunnel in the San Cristobal Valley on the Luke Air Force Range in Yuma County, Arizona. The proposed construction project will provide essential cost and construction data to analyze conceptual protective structures for the mobile, land-based Intercontinental Ballistic Missile (ICBM) System known as MX. The trench will also serve as a test bed for mechanisms designed to punch through the tunnel roof and erect a dummy missile to simulate launch position. Both tunnels will involve trench excavations approximately 22 ft (6.7 m) deep by 17 ft (5.2 m) wide to allow continuous slip-form placement of two concrete tunnels with dimensions of 13 ft (4 m) and 16.5 ft (5 m) inside and outside diameter, respectively. The two tunnels would total approximately 21,500 ft (6,553 m): a 1,500 ft (457 m) section providing procedure and equipment shakedown and the breakout test bed; and a 20,000 ft (6,096 m) section providing cost and construction data.
