John Brown and Parsons compete on marine machinery

John Brown's Clydebank yard is presented as one of the most important sites in the technological history of British shipping. Brown and Parsons both contributed to the development of turbines, higher speeds, and high-pressure machinery. Their rivalry pushed the firms to improve rather than rely on an established design. That mechanism depended on enough Royal Navy and merchant orders to support more than one capable supplier. Shipyard competition therefore produced engineering progress because a large order market could sustain competing specialists.
