Symphony of the Seas is an Oasis-class cruise ship built by Chantiers de l'Atlantique in Saint-Nazaire, France, and operated by Royal Caribbean International. Upon completion, she became the world's largest cruise ship by gross tonnage, holding that distinction until being surpassed by her sister ship Wonder of the Seas. At approximately 361 meters in length, Symphony of the Seas is roughly 30 meters longer than the largest military ships ever built, the U.S. Navy's Nimitz-class aircraft carriers.
