The spacecraft pictured is just a model, but according to IDRW India plans a vehicle to test reusable unmanned spacecraft technologies. The Russian's are also working on a reusable unmanned system.
Though the X-37B programme is shrouded in
secrecy, its possible applications boggle the mind. Such spacecraft could be sent up quickly to
replace satellites shot down early in a war, and theoretically take evasive
action if attacked. They could also have a role in guiding UAVs and UCAVs over
enemy territory, and even carry weapons into space, either for attacking
targets on earth or for disrupting enemy satellites.
