  1. sister ship

    A sister ship is a ship that is built based on the same design and specifications as another ship, and as such, shares many similarities. They are typically built in the same shipyard and are part of the same class or series. In essence, it's a vessel that is almost an identical twin of another ship. Sister ships share similar size, capacity, speed, and functionality. They are often constructed for and deployed by the same company or navy.


  1. Sister ship

    A sister ship is a ship of the same class as, or of virtually identical design to, another ship. Such vessels share a near-identical hull and superstructure layout, similar displacement, and roughly comparable features and equipment. Often, sisters become more differentiated during their service as their equipment are separately altered. For instance, the U.S. warships USS Iowa, USS New Jersey, USS Missouri, and USS Wisconsin, are all sister ships, each being an Iowa-class battleship. The most famous sister ships were the White Star Line's RMS Olympic, RMS Titanic and HMHS Britannic. Other sister ships include the Royal Caribbean International's Explorer of the Seas and Adventure of the Seas. Half-sister refers to a ship of the same class, but with some significant differences. One example of half-sisters are the First World War-era British Courageous-class battlecruisers where the first two ships had four 15-inch guns, but the last ship, HMS Furious, had two 18-inch guns instead. Another example are the American Essex-class aircraft carriers of the Second World War that came in "long-hull" and "short-hull" versions.
