It’s something of an open secret that maritime special operations forces around the world rely on a wide array of highly specialized water craft, such as high-speed, low-profile speed boats, miniature submarines, and more. Now, one company, SubSea, is trying to combine a number of these features into single design it calls the Diver Delivery Unit (DDU), which can transform from a speedboat to a mini sub and back again.
The DDU concept is centered on a symmetrical twin-hull design, both of which could carry personnel or other equipment. The United Kingdom-based firm says the final arrangement will be both modular and scalable to allow for a wide variety of missions, including special operations raids, hunting drug smugglers, patrolling ports, and even performing research and exploration tasks.
Eight electric fans will power the boat underwater, with two at the rear of each hull and another two in each of the twin bows.
