The Waffle-class drop ship is a starship in mass and displacement, and in many of the other technical senses of the word. But it is not a starship.
The Waffle shares with a variety of small craft (the Marlinspike-class boarding torpedo, the Piton- and Fist- drop pods, and the like) a certain characteristic. Namely, that it is extremely likely, if not absolutely certain, that it will be used only once before being destroyed.
A starship has a name, a spirit, and a history that often goes back through multiple incarnations. Such things, it is generally felt, do not belong with such consumable vessels.
For this reason, the Waffle and its fellows are, by IN regulations, designated “ammunition”.
