The six-man Italian designed UOES-3 is competing with the larger British built ten-man UOES-2 design which is also undergoing trials. The UOES-3 is small enough to fit inside an extended Dry Deck Shelter (DDS) which can be carried on the back of an attack submarine. It can also be launched from a surface ship, either by crane or via a moon pool in the bottom of the vessel.

A rare view inside the submarine through the forward hatch. The compartment closest to the camera is the diver lock-out chamber with an exit hatch overhead and a hatch at the back entering into the main cabin. In order to lock-out the SEALs sit on the mesh seats while the chamber fills with water. They can then open either the upper hatch, or a similar one beneath their feet (not visible in this shot). You can also see the cylindrical sonar above the hatch.
