I like your ideas for standardizing the making of the AI design creation files. I would, however, suggest that the ship sizes be a 100kt bigger so that the smaller ships are easier to design for the AI. It should be possible to get a ship’s engines to take up 40% of its hull size by using mounts for the engines. e.g. a escort ship(250kt)would have four engines with a tonnage space taken of 25kt each, a heavy dreadnought ship(1500kt)would have four engines with a tonnage space taken of 150kt each. It is also possible to increase the cost of the engines and their supply usage.
