From their web site:

[June 24: We were just informed that the Titan IV flight will launch no earlier than September and may very well be delayed until October or November, depending upon what issues arise (due to overflight concerns, Falcon I is required to launch after Titan IV). As a result, you can expect that our first launch will now be from our island launch complex in the Kwajalein Atoll.

The customer for this mission is DARPA and the payload will be FalconSat-2, part of the Air Force Academy’s satellite program that will measure space plasma phenomena, which can adversely affect space-based communications, including GPS and other civil and military communications. Nominal launch date out of Kwajalein is late September. Our TacSat-1 mission for the Naval Research Laboratory will follow the Titan IV launch from VAFB.]
