Inertia-less Tech
This tech lets ships go from 0 speed to high speed with no acceleration. Indeed, this would cause a very high g-force, which would make pilots go splat, but the inertia-less tech is a field, where everything in the ship would not be subject to inertia. This can be done without reducing mass of the ship.
Self-replicating Tech
I realized that this tech is restricted, as I can't use zero-point energy manipulation until much later, but I can still use this. Anyway, this is just access to technology where it can reproduce itself.
Self-replicating Missiles
These missiles would produce themselves on their way to their target. They have the average speed of a missile. It compresses the missile it is creating until it launches the missile it created. It repeats. Every 15 seconds, the number doubles. If you have one missile, you would have 2, then 4, then 8, 16, 32, 64, etc. It gets its resources from the exhaust, which is partially inside the missile, but still exposed to the outside to have propulsion. The resources come from the exhaust. Said resources are used to produce more missiles. The longer the missiles survive, the more they build.
Self-replicating Energy Missiles
These are balls of energy that is able to replicate itself by collecting energy. It takes around 5 seconds to double itself by amplifying the amount of energy it has, and then use it to produce more of itself. These missiles don't have any inertia, making it have complete maneuverability. They have the average speed of the missile. The longer they survive, the more they build.
