Wurrfler (Nazi U-Boat)

Mobile Nazi U-Boat (the Wurrfler) serving as the transport vessel for the Ark of the Covenant and captive Marion Ravenwood. The submarine features a conning tower (an exposed steel tower and access platform on the deck, housing the periscope and serving as a vantage point during submergence), which is a critical structural component for navigation and crew access. The conning tower is distinct from the periscope instrument mounted within it but is integral to the submarine's operation.
