Definition
A sister ship is one of a group of ships built to the same design. Think of them as twins, but for boats. They share identical blueprints, dimensions, and capabilities. This often results in similar performance and handling characteristics. Sister ships may have slight internal variations but are fundamentally the same. They are often part of a fleet, operating together. Think of a squadron of fighter jets, all identical in design. Each sister ship serves a distinct role, but they share common capabilities.
