The word "jumpship" is used to refer both to:

1) a specific combat role (light combatant with missile defense: i.e. Stinger and Eldritch), and to

2) a class of ships, encompassing explorers, (basic) jumpships, jumpcruisers and jumptransports.

There is no analogue for starships or ramjets.

To reduce confusion, I suggest that the basic jumpship combat role be renamed to something like "jumpfighter", "jumpfrigate", or "interceptor".
