Unfinned

Unfinned is a term used to describe something that lacks fins. Fins are typically flat, projecting structures found on fish and some other aquatic animals, used for stability, propulsion, and steering. In a broader context, the term "unfinned" can also refer to objects or structures that are designed or manufactured without these appendages. For example, an unfinned rocket might be designed for specific aerodynamic conditions where fins are not necessary or could even be detrimental to performance. Similarly, a ship could be described as unfinned if it does not incorporate stabilization fins. The absence of fins can influence the hydrodynamic or aerodynamic properties of an object, affecting its movement and behavior in water or air. The design choice to be unfinned is usually driven by specific functional requirements or operational environments.
