The launch control center, or LCC for short, is the main control facility of any U.S. ICBM complex. From here, the crew can monitor the complex, launch the missile, or relax in the living quarters (depending on the ICBM system). The LCC is designed to provide maximum protection for the missile combat crew and equipment vital to missile launch.
All LCCs were dependent on a missile support base (MSB) for logistics support. For example, Minot AFB is the MSB for the 91st Space Wing. This is important to note, for some wayward maintenance crews have strayed from their MSB/missile complex, into another base's complex unwittingly.
Three types of Minuteman LCCs exist:
There are four configurations of the LCC, differing primarily in the amount and location of communications equipment. Functionally, there are three LCC designations. One Alternate Comniand Post (ACP) LCC is located within each Minuteman wing and serves as backup for the wing command post. Three Squadron Command Posts (SCPS) serve as command units for the remaining squadrons within the wing, and report directly to the wing command post. The ACP doubles as SCP for the squadron it is located within. The remainder of the LCCS (16) are classified as primary LCCS. Four primary LCCS are located within each squadron and report to their respective command post.
The Titan LCCs held four crew members: the Missile Combat Crew Commander (MCCC), the Deputy Missile Combat Crew Commander (DMCCC), Ballistic Missile Analyst Technician (BMAT), and the Missile Facilities Technician (MFT).
Titan II had a three story LCC dome. The first level was the crews living area and contained a kitchen, bathroom, bedroom, and a small equipment area that housed an exhaust fan and a water heater. The second level was the launch control area and held the LCCFC (Launch Control Complex Facility Console, the main launch console), the ALOC (Alternate Launch Officer Console), the Control Monitor Group (monitored the missile), and several offer pieces of equipment. The lowest level, level 3, held communications equipment, the two battery backup supplies, the sewage lift station, the motor-generator, and several other pieces of equipment.
There were two types of Titan II sites: standard, and ACP (alternate command post) sites. ACPs had all of the equipment that one would find on a standard site plus additional communication equipment.
The LCC outer structure is cylindrical with hemispherical ends. Walls are approximately 4.5 feet thick. A blast door permits entry into the LCC from the tunnel junction. An escape hatch 3-ft in diameter is located at the far end of the LCC. The escape hatch and associate tunnel are constructed to withstand weapon effects and allow personnel egress in the event of damage to the vertical access shaft. Essential LCC launch equipment along with the missile combat crew are located in a shock isolated room suspended within the blast−proof outer structure. The room is steel and suspended as a pendulum by four shock isolators (see picture below).
The Minuteman LCC differs from previous missile systems in that it only held room for two personnel, the Missile Combat Crew Commander (MCCC) and the Deputy Missile Combat Crew Commander (DMCCC).
