This is actually quite similar to the process of naval architecture
since about 1890. It's slightly complicated by the fact that in water,
the power needed is approximately proportional to the cube of the speed.
(Though it's more like the square for very long ships, but that's
another matter).

A 60%-of-mass-for-thrust Battleship is essentially a Battlecruiser. The
reason that Battlecruisers were so big in terms of displacement was
simple. You take a n 18,000 ton battleship design, and give in another
12,000 tonnes of engines (and hull etc, it's gotta float).
