The The Sullivans-class was a class of Federation starship that saw service during the 24th century. The Bradley class launched several specialized sub-models, such as the Bradley defensive cruiser and the Ki Rin Improved Strike Cruiser. A number of vessels were also converted to intelligence gathering and penetration roles and were involved in a number of operations under Project Gray Ghost. The final and most important feature is the ability to land. This gives the design a true multi-role capability.
