France's Naval Group is developing a new XLUUV (Extra Large Unmanned Undersea Vehicle)

Prototype is already in the water, it's been worked on since 2018ish. ~10 meters (33 ft), up to 20 meters (66 ft) with additional power options. Displacement: ~10 tons

Service version will have a weapons/equipment bay.

Our own Covert shores did a nice comparison image of different nations LUUV/XLUUV efforts.

Quite an organic, almost whale like shape. Curious about how the typology of UUVs has evolved, are these "extra large" just by the virtue of being the largest at the moment? Minesweepers utilize smaller vehicles but at least in the civilian market there are all kinds of diving robots that I'm pretty sure are at least as large as these UUVs.
