This naval vessel is designed for stealth transportation of goods and soldiers from shoreline locations to offshore platforms and vessels. With three powerful propellers in the back, it can achieve great speeds for a submarine. Its thick hull makes it essentially immune to small arms fire.
It is incapable of long-distance travel.
The submarine appears as a map prop in the Renegade singleplayer. At the end of The Plot Erupts, Havoc infiltrates it right after Nod soldiers load up the GDI prisoners. The sub then travels to a Nod freighter to drop off supplies and the POWs. After setting the charges on the ship and freeing the prisoners in Stowaway, Havoc escapes in the submarine just as the ship is blown up.
