The Red Springs-class submarine is a guided-missile submarine based on a modified Flight II Seawolf-class submarine with a plug inserted in order to provide space for 22 missile tubes. Each tube measures 83 inches in diameter and provides space for 7 Tomahawk missiles. This design was chosen in order to minimize the number of penetrations through the hull for Tomahawk missile carriage. The plug measures a total of 100 feet in length, increasing the displacement of the ship by 3502 long tons. The removal of other systems (most notably the 12 cell VLS nest) has reduced the displacement and length, resulting in the characteristics listed.

Despite being ordered in near simultaneity with the first Seawolf-class boats, design delays resulted in a much later commissioning date for all 5 of the boats. The Tian Xia Navy is the only operator of this class.
