The Launch Control Center (LCC)

Launch Control Center (LCC)
The four story high building comprises four firing rooms on the third floor for prelaunch and launch activities.
The firing rooms have large angled windows which provide a panoramic view on the two launch sites. The windows can be protected by pivoting the large louvers in front of the windows. These louvers can be pivoted in sets of five. In this photo can be seen that of the far left firing room (Firing Room 4) one group of louvers is fully opened the second half closed and the third group closed.
On the right side of the LCC buiding the two story high bridge connecting the LCC with the Vertical Assembly Building (VAB). The top story of the bridge is a walkway, the lower story is a utility bridge containing cable trays for the numerous connections between the firing rooms and the VAB.

LCC cross section
The light-red section is depicting one of the four firing rooms. From right to left: the console area for the launch management team, for the engineering teams and the area with the instrument racks.

On the right side an angled wall of large windows to provide a panoramic view on the launch site 5 km away. Fifteen large louvers were installed on the outside which could be quickly pivoted at their angled vertical center axis to form a protective wall against incoming debris in case of a catastrophic event on the launch pad.

Six 3 by 3 meter display screens kept the launch management team informed about the progress of the launch operations. The four display screens in the middle were used to display images from various video camera's located on the launch pad and on the launch umbilical tower and to display data. There were two display screens on either side of the four display screens mentioned above. The large display on the left side was used to display significant launch events and the display on the right side was used to show which tracking stations were receiving downlinked data from the launch vehicle.

Firing Room 4

Not equipped and never used for the Apollo missions.
It was used to display program evaluation and progress & planning charts during the construction of Launch Complex 39 and the integration of Apollo/Saturn systems.

LCC Floor 3
The Launch Control Center has four large rooms for four firing rooms.
The rooms were corresponding to the four High Bay areas in the Vertical Assembly Building (VAB). This design allowed for a simultaneous assembly and system testing of four launch vehicles. In the mid 1960's it was concluded that three High Bays and the corresponding three firing rooms were sufficient to meet the planned launch rate. The rooms which were used for the various missions are mentioned above.

LCC Floor 4
This floor is comprised of conference rooms, office areas, and mechanical equipment rooms among which the large rooms in which the display equipment was located for the six large display screens in each firing room.
