New 8-person Swimmer Delivery Vehicle revealed
Italian SDV and Special Forces midget submarine builder DRASS revealed their 8-man design at EuroNaval 2018. The secrecy surrounding Italian Swimmer Delivery Vehicle (SDV) manufacture is legendary. Drass are an established name in the defense industry supplying hyperbaric chambers for diver decompression. They also offer a range of SDVs and midget submarines based directly on the previous Cos.Mo.S designs. The DS8 is the first SDV design which substantially steps beyond the Cos.Mo.S design catalogue.
The layout differs significantly from the DS6 6-person SDV. The crew and passengers are seated in two separate cockpits, separated by the battery container.
The DS8 is can be configured in two ways; the standard layout with eight divers, and the Heavy Load layout (DS8HL) with just six divers but additional cargo containers for diver propulsion vehicles (DPVs), spare rebreathers, additional hot water system or other gear.
