Versatile, small high-speed craft are becoming an essential tool for modern naval and paramilitary forces, however the roles of these vessels are expanding. Rolls-Royce's Andrew Rice looks at the evolution of the Combat Boat 90. More than 10 years ago, revised Swedish defense planning called for a radical increase in the mobility of coastal defense forces. As a result, the Combat Boat 90 project began, developed by the Swedish Defense Material Administration (FMV). A concept that is proving to be a world beater. The prototype contract for two units required Swedish shipyard Dockstavarvet to produce all calculations and engineering/construction drawings based on the FMV project design. Within 10 months of contract award, trials on the first prototype were a success.
