Now that I think about it, Carrier designs may explore as well.
The main concern with building a ship-heavy "Hesitant" race is maintenance--you'd need some sort of special economic tech to allow them to build masses of ships. And drones. Drones would be great--lots and lots of drones all over the place. Of course, they'd all be gone after the first battle, but what a battle that would be!
