>Seawolf-class
Not after she was refit:
What sets the USS Jimmy Carter apart from other Seawolf-class subs, are the modifications which turned it into a unique Multi-Mission Platform (MMP) submarine. During construction, an additional Ocean Interface (OI) section, sometimes referred to as "the plug," was inserted into its hull, providing extra space for various missions and equipment. The OI section offers a larger payload opening to the sea, and serves as an underwater hangar for a changing variety of roles.
This large MMP area outside the pressure hull, but still within the skin of the ship, is ideal for flexible payloads and naval special warfare (NSW) missions. This internal MMP design keeps a smooth hydrodynamic hull shape that has minimal impact on the ship's draft, while providing a place for any next-generation systems needed in the future.
In addition to the OI section, the SSN-23 also reportedly has “Auxiliary Maneuvering Devices” fitted fore and aft that may allow her to keep station over selected targets in odd currents, as well as an Advanced Communications Mast (ACM).
