A 'sistership' refers to two or more ships (or sometimes other vehicles like planes) that are built to the same design. Think of it as identical twins, but for boats. They share the same blueprints and specifications, meaning they look and function very similarly. This is often done for efficiency and ease of maintenance. Sisterships might have slight modifications over time, but their core design remains the same.π’ It's like when car manufacturers release the same model year after year with very minor tweaks.
