This “device” may only be purchased when a craft is first built. In other words, either the craft is designed for atmospheric flight or it isn’t. Starships with Aerodynamic Designs take no penalty in atmosphere, and may use active defense in atmosphere. A starship with this advantage may also land on the surface of a planet. The bigger a starship is, the more expensive an Aerodynamic Design becomes.
