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 starts on Access Portal
    and Blast Lock Area. (silo on left)

    Launch Duct Flame Deflector Construction
   on Level 8 and Level 9 of the Silo.

    Construction continues on the
    Blast Lock Area, Access Portal, and Silo.
    Dirt is back filled as construction
    progresses.  (silo on right)

    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.

    Center Level 2.

    The finished product.  This is what
    the missile complex looked like after

Certain parts of the construction were not shown in these pictures or any
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 missile,
unlike the Atlas or Thor missile systems which loaded the propellants during
the launch sequence.  Also, the Titan II missile was launched from underground,
unlike some of it predecessors which were raised above ground to be launched.
There was also an 8,000 gallon diesel fuel storage tank the held fuel for the
Standby Power Generation systems (located underground topside).
