Missile launch control center
Three types of Minuteman LCCs exist: There are four configurations of the LCC, differing primarily in the amount and location of communications equipment.
The Minuteman LCC is an underground structure of reinforced concrete and steel of sufficient strength to withstand weapon effects.
The Minuteman Combat Crew has voice communications capability with all the LFs of the flight which it commands.
There is also a voice circuit called the EWO (Emergency War Order) which links the squadron command posts (CPs).
The term "EWO" used here is not to be confused with an actual Emergency War Order message from the National Command Authority.
Message traffic over the LF, HVC, and EWO voice circuits are transmitted via the Hardened Intersite Cable System.
Each Combat Crew also has access to commercial telephone lines for ordinary civilian communications.
The escape hatch and associated 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 and communications gear, along with the missile combat crew, are located in a shock isolated compartment suspended within the outer structure.
[1] The LCC's electronics are fully shielded from Electromagnetic Pulse damage with carbon block surge arresters.
From 1967 to 1998, the ALCC mission was performed by United States Air Force EC-135 command post aircraft.
Starting on October 1, 1998, the ALCS has been located on board the United States Navy's E-6B Mercury.
The ALCS crew is integrated into the battle staff of the USSTRATCOM "Looking Glass" Airborne Command Post (ABNCP) and is on alert around-the-clock.
The Netlink system brought internet access underground for missile combat crews.
Previously, each MAF was equipped with the ICBM SHF Satellite Terminal (ISST) communications system.
Instead of replacing the command and control equipment, the 'old' Minuteman CDB C2 system was modified for the 50 Peacekeeper ICBMs.
