I am faced with a vexing problem in my current game and am pondering many options to resolve the problem. I figured to assist in this I would post the situation here and see what thoughts more experienced players may be able to offer. Some background first:
I settled and established several mining colonies in a binary star system. The secondary star, and its accompanying bodies, are extremely far away from the primary start where the jump points any my populations are located. Extremely far away specifically means 2064.28 billion KM. At best, my warships are equipped to go about 50 billion KM. The problem, beyond the distance, is that I am reasonably sure there is a NPR way out there that has itself been confined to the bodies around the secondary star due to the distance. I am not a fan of waiting around for them to eventually make it to my colonies and want to deal with them.
So, the question is, how to project military force at that distance? Even with refueling tankers I don't see how it would be viable. I've considered designing a more fuel efficient military engine but I'm still not sure at this point it will get me the distance I need and so I am interested in other suggestions. Thanks!
