I was pondering how I wanted my technology to feel in the upcoming Space Opera game, and started thinking about starships. Specifically, how are they designed.
The way I'm leaning now is a slightly hard-science universe.. specifically, no artificial gravity/anti-grav/magic thrusters. With antimatter as an energy source, we can get very effective reaction motors without the need for huge amounts of reaction mass. Make the FTL rules work for reasonably close approaches to the star, and you've got a system that is both realistic and playable.
I'm seeing starships as being modular. You start with a core, a long cylinder with the power/drive/radiator bundle at one end, and the control room at the other. Along the core there are attachment points for any number of modules, rotation points for spin habitats, interface craft, etc. This allows endless customization and adaptability from a few basic models of core. Needless to say, most star ships are not capable of entering atmosphere (and with tanks filled with antimatter, nobody wants them to land.
Then the image hit me, such a ship carrying dozens of white cargo containers with "PODS" stenciled on their sides... :)
Anyway, most of the core worlds will have beanstalks (or more than one. I'm picturing Earth with three.) to facilitate rapid transfer of cargo and passengers. Frontier worlds will need to use any variety of methods from fusion air ram shuttle to brute force chemical rockets to get to and from low orbit. Most ships carry at least one interface craft so the crew can go dirtside when necessary.
Military craft will be less modular out of necessity. The connectors will be weak points in battle. Naval ships will be bulkier, have huge drives, and be designed to operate for a limited time if their radiators are disabled or pulled into the hull. (I imagine that part of the reason for evacuating the ship to vacuum in battle is to cut down on the heat transfer.) The most common weapon is the missile; usually armed with a bomb-pumped X-ray laser. Lasers are used at shorter ranges, and are the primary armament for fighters (which I'm seeing as looking a lot like the Starfuries from Babylon 5.)
