Description
This class formed the backbone of the US submarine fleet for much of the cold war. It is an evolution of the Permit design, but focused on improved quieting, habitability and optimized for ELINT missions with increased space for electronics and a larger sail permitting more masts to be accommodated. All were upgraded with BQQ-5 and TB-16 towed arrays, as well as Mark 48 and the ability to fire UGM-84 Harpoon as well as UGM-109 Tomahawk missiles later in their lives.
