For people who are unaware, the Pentagon currently uses its own satellite communications system, the WGS (Wideband Global Satcom) for remote communications. However, the DOD is considering ending that program, instead using commercial satellite communications systems to do so- their budget is limited, and bandwidth demand is increasing.
Though commercial comsats seem like a good way to do extend capabilities for lower cost, (not to mention increase redundancy) and studies to do so have been made, but the process has been going very slowly so far. Obviously, there are people against this, but some believe that commercial comsats cannot deliver for specialized DOD needs. There is also the possibility that such a system would undermine the security of a currently very secretive system (something the DOD wants, for the obvious reasons that they are a military service, and communications are essential).
