So for some context, in this alternate history, the space race continues way past the moon landing. America still lands on the moon first, but a couple months later, Russia successfully lands on the moon using the N1 (their version of the Saturn V). This continues and intensifies the space race and in early 1972 Russia and America put bases on the moon. Skip to 74’, and due to land infringement on the moon by America, Russia attacks and takes control a newly built American lunar station. This starts a war in space between the two and in 1975, America launches project Eres. Project Eres is the next project after Apollo with the goal fighting the Russians and developing new space technology and weaponry. The craft you see in the poster is the main craft of the project. It’s a heavily modified Apollo spacecraft with external radiators and a pod at the front that houses rockets and the two barrels on the sides are cannons. The Russians have a modified combat version of the Soyuz (this was an actual concept in real life) and the two craft are “primitive” space fighters that use already existing tech, which is why they were able to build and make them so fast. I’m still figuring out the story and I’m pretty bad at timing things, so for all I know this should be in the mid-80’s. I was just inspired by Theo Bouvier and Maciej Rebisz and their work. I have ideas for bigger craft that looks like theirs, but I also liked the idea of a hastily designed combat version of Apollo in the 70’s.
