New Large Chinese Submarine With Very Unique Feature Just Caught On Satellite Imagery
4th June 2026
A new type of submarine that appears to lack a traditional sail has emerged in China. The same shipyard launched a smaller ‘sailless’ submarine — a technology demonstrator — eight years ago. More recently, a top Chinese shipbuilding conglomerate put forward a concept for an uncrewed underwater vehicle (UUV) with a broadly comparable hullform. Designs of this kind can offer benefits in terms of speed, maneuverability, and reduced acoustic signature, but also have major drawbacks.
TWZ has obtained imagery of the submarine in question at JN (Jiangnan) Shipyard in Shanghai on June 1, as seen at the top of this story and below, from Vantor (previously Maxar Technologies). The boat, the name and/or designation of which are currently unknown, first appeared there sometime at the end of May, according to Naval News. That outlet was first to report on this development.
From the imagery, the submarine does not have a traditional sail. However, the exact shaping of what is present is also not entirely clear from the view that is currently available. As noted, JN Shipyard is known to have built at least one other ‘sailless’ submarine in the past, which we will come back to later on.
