![]() Engineers, seeking R&D funds, propose new components for an existing submarine’s engine room that are considerably lighter than the existing components.(Designers of submersibles are not included in this count.)Įxamples of proposed submarine design changes include: ![]() ![]() In the United States, this group probably numbers fewer than three dozen people, more than half of whom are retired or working in other areas of ship design or in other fields. In fact, there are very few people who do understand the intricacies of submarine design and those who understand them best are the naval architects who, at one time or another, have performed studies related to designing a new submarine and/or evaluating the total-ship impacts of major design changes to existing designs. Unfortunately, with very few exceptions, these well-intervention people do not understand the intricacies of submarine design and many of their conclusions regarding the ship design impacts of their ideas are erroneous. They have, over the years, voiced their opinions (loudly or quietly) about what the next US Navy attack submarine ought to look like or the effects of introducing new hardware into an already existing submarine design. It sometimes appears that everyone inside the Beltway is a submarine designer-expert witnesses testifying before Congress (and members of Congress too), senior DOD and Navy personnel, journalists and novelists, scientists and engineers working in submarine-related R&D, and others. His last position was as Head of Submarine Preliminary Design and as Principal Naval Architect for the Virginia class. He is a naval architect and retired from the Naval Sea Systems Command in 1999 after 35 years of working in early stage submarine design and submari11e-related R&D management.
