It is not possible to name a class of missile cruisers 'Longbow'.



Why? Because ten turns from now when the enemy starts using flak defenses against your missiles, you will need to refit them into beam cruisers. But you cannot rename them. And you cannot refit from one cruiser class ship to another.



This subverts naming conventions, and makes identifying your own ships roles difficult.



Option #1:

Make the refit system able to refit to any model of that hull class. When you select refit, then you choose which model to refit the current ship up to.



Option #2:

Make it possible to rename a ship class. If a ship class is being refitted to a gunship instead of a missile ship, then allow that information to be present in the name.



Either of these options will make it possible to maintain a 'Longbow' class ship that actually contains meaning in it's name.
