BAE SYSTEMS Submarines Business Group (formally Vickers Shipbuilding) was one of the first Flowmaster users. To date, they have created over 600 models to design, build and support major UK Naval Warships and Submarines.

BAE Systems Submarines analyzed many of the Astute systems to enhance and derisk the design. Examples include the trim, ballast and hover systems, which were extensively modeled in FloMASTER to develop and optimize the design to meet the contractual requirements.
