Is OP still around? It would be interesting to know what they decided to use.
They were last active 5 days ago according to their profile, so yes.
Conjures up too much of a “obsolete battleship in space” image.
In fact, I kind of have an issue with the whole Lucas Doctrine “space navy = seagoing navy” analogy with its equivalents of frigates, destroyers, cruisers, battleships and carriers as ships of increasing size, armor, armament and aircraft complements fighting the Battle of Midway in space. As someone already pointed out, physics renders tiny space fighters as impractical and there is little need for a space capital ship to have a screening force of small destroyers and frigates.
A spaceplane is a craft that can fly as an aeroplane in the skies of Earth or any other similair planet or natural satellite, but also able to move in outer space working as a spacecraft. It hasn’t with size to do.
