China has showcased its secretive underwater combat vehicle, the SDV-01, at the Saudi Arabia defence show. This marks a rare overseas debut for the swimmer delivery vehicle. The SDV-01 can carry multiple frogmen for missions like combat diving, underwater demolition, and reconnaissance. The show runs from Sunday to Thursday and features a strong Chinese presence, including the latest naval weapons. This highlights the People’s Liberation Army’s efforts to build a blue-water fleet and boost shipbuilding. The SDV-01’s appearance signals Beijing’s push to sell advanced underwater special operations tech in the large Middle Eastern market.
