The Sea Wolf-class attack submarine USS Jimmy Carter (SSN 23) sits moored in the Magnetic Silencing Facility at Naval Base Kitsap Bangor for her first deperming treatment. The deperming process reduces a ships electromagnetic signature as she travels through the water. Jimmy Carter is the third and final submarine of the Sea Wolf-class. A unique feature of the Jimmy Carter is a 100-foot hull extension called the Multi-Mission Platform, which provides enhanced payload capabilities, enabling the submarine to accommodate the advanced technology required to develop and test a new generation of weapons, sensors and undersea vehicles. www.navy.mil
