FALCON USER’S GUIDE into the launch site’s main data system, allowing easy data transfers between the control facility, the pad and the range, along with required external users and agencies. A customer room that can accommodate eight people is provided within the facility for customer technical management personnel. VANDENBERG AIR FORCE BASE, CALIFORNIA SpaceX operates a Falcon launch site at Space Launch Complex 4 East (SLC-4E) at Vandenberg Air Force Base (VAFB), California (Figure 6-5). SLC-4E was also previously used by the US Air Force for Titan III and Titan IV launches, and it has been extensively modified by SpaceX to accommodate Falcon launch vehicles. The facilities include the PPF, vehicle integration hangar, customer office area, pad customer room, launch pad, and launch and landing control. The PPF is attached to the north side of the vehicle integration hangar as shown in Figure 6-5. The two facilities share a common door through which an encapsulated payload will pass for integration to the launch vehicle. The customer office area is within walking distance of the PPF and is available to support customer administrative needs. There are multiple offices and conference rooms available in the building and sections of the building can be closed off as necessary to separate working areas between organizations. The pad customer room is located next to the launch pad and equipped to support customer EGSE racks and work stations during payload processing at the pad. The Launch and Landing Control (Bldg 8505) is located on the North Base and is equipped to support customer electrical ground support equipment racks and workstations for day of launch activities. Figure 6-5: Space Launch Complex 4 East at Vandenberg Air Force Base, California The SLC-4E launch pad is located at 34˚ 37.92’ (34.6320°) N latitude, 120˚ 36.64’ (120.6107°) W longitude. Launch azimuths from SLC-4E support high-inclination LEO orbits, including polar orbits and SSO (Section 3.1). SLC-4E processing and launch operations are described in Section 8. © Space Exploration Technologies Corp. All rights reserved. 44
