Space Vehicle Upper Stage Request for Information

​​​​​​1.    DESCRIPTION
Space Systems Command (SSC) Space Combat Power’s Orbital Warfare and Space Domain Awareness mission areas field and sustain space systems.  Assured access to space is instrumental in the rapid fielding and replenishment of these space systems.  Many of these systems reside in Geosynchronous Orbit (GEO).  Immediate space vehicle placement in GEO is essential for the success of the mission.          

The vast increase in commercially available launch service options to Low Earth Orbit (LEO) and Geosynchronous Transfer Orbit offer the opportunity for significant schedule flexibility to the U.S. Government.  For the purposes of this RFI, vertical lift options that provide transport to Geosynchronous orbit (GEO) via Geosynchronous Transfer Orbit (GTO) are of interest.      

Space Combat Power seeks to evaluate emerging launch systems for potential integration into its product line as part of a hybrid launch vehicle transport system. 

2.    BACKGROUND
Commercial satellite communication systems transitioned from fully chemical solutions to primarily electric propulsion solutions to travel from GTO to GEO.  The GTO to GEO transition time presented by electric propulsion systems is not a viable option for the Space Combat Power mission area.  Space Combat Power is seeking information on orbit raising solutions that minimize the transfer time from GTO to GEO, essentially placing the satellites in their desired orbit as quickly as possible, while being able to take advantage of the schedule flexibility offered by commercially available (primarily LEO) launch service providers.                  

3.    RESPONSE FORMAT
