As of 2024, the largest cruise ship currently under construction and making significant headlines is Star of the Seas, the second vessel in Royal Caribbean's revolutionary "Icon Class." Following its sister ship, Icon of the Seas (which took the title of world's largest upon its debut in early 2024), Star of the Seas is being built at the Meyer Turku shipyard in Finland. These ships are massive engineering marvels, weighing approximately 250,800 gross tons and measuring nearly 1,200 feet in length. Star of the Seas is designed to carry up to 7,600 passengers at maximum capacity (plus 2,350 crew members). Like its predecessor, it features "neighborhoods" such as Thrill Island (home to the largest waterpark at sea) and Central Park. A major technological highlight of this build is its propulsion system, which is powered by Liquefied Natural Gas (LNG), making it one of the cleanest-burning large-scale cruise ships in the world. Scheduled to debut in the summer of 2025, Star of the Seas represents the pinnacle of "mega-ship" construction, focusing on multi-generational family entertainment and sustainable maritime engineering on a scale that was unimaginable just a decade ago.
