Abstract : The T-AGOS class 3 and 4 ships are under consideration by the United States Air Force for use as sea-based radar platforms. In order to meet mission requirements, their roll motion must be reduced. Several roll damping methods appropriate for this class of ships are considered. Bilge keel stabilization is studied in more detail and various sized bilge keels are analyzed, utilizing a seakeeping prediction program, for the full range of ship speed and sea states. Operability indices at several roll angles and for various bilge keel shapes are developed and compared. Design considerations based on the above studies are made.
