Construction of the 390 SMW
The construction of the Titan II missiles sites
started out looking like a strip mining operation.
Soil was removed in this manner until the required
depth was reached for construction to start on
the Control Center, Blast Lock Area and Access
Portal and digging started for the Launch Duct
and Silo Equipment Area. The following photos
show the progress of the construction to
completion of a missile complex.

Construction of Control Center Dome,
Blast Lock Area, and Access Portal
completed. Construction of Silo Head
Works continues. Preparations are being
made for placement of Short and Long
Cableways to connect the Control
Center to the Missile Silo.

Silo Head Works and topside area
are being prepared for placement of
the Silo Closure Door ( sitting on the
left side of photo). This was constructed
of 740 tons of concrete and steel. It
protected the missile from damage from
a blast and weather. The Door was
opened using a combination of hydraulic
actuators and steel cables.

The finished product. This is what
the missile complex looked like after
Certain parts of the construction were not shown in these pictures
books that I have read. The complex topside had underground Emergency
Dump Tanks that were used to off load missile propellants in an emergency.
Missile propellants in the Titan II system were stored on board the

There was also an 8,000 gallon diesel fuel storage tank the held fuel
