Quantum Class comprises Quantum (2014), Anthem (2015), Ovation (2016), Spectrum (2019), and Odyssey (2021). At roughly 168,000-169,000 GT they are the smallest of Royal's flagship classes but carry the most complete technology-and-activity onboard programme in the fleet.
Signature features include North Star (a glass observation capsule that extends 90 metres above sea level), Ripcord by iFly (indoor skydiving), SeaPlex (bumper cars, trapeze school, and roller-skating), and RipCord's aft-deck complex. The class was the first to introduce virtual balconies for inside cabins and the Two70 aft observation venue with robotic screens.
Deployment is deliberately global. Anthem and Odyssey serve the North American market; Ovation, Quantum, and Spectrum are Royal's Asia-Pacific flagships, based year-round in Singapore, Shanghai, and Brisbane respectively. Quantum-class ships are the reason Royal is the market-leading Western cruise brand in China and Australia.
