Hunley-class

SCB 194 Type. Among the last submarine support ships built for the US Navy, both ships of this class (Hunley (AS-31) and Holland (AS-32)) acted as base ships for submarine operations during the Cold War. In fact, so long was Holland at Ballast Point near San Diego, that she became known derisively as "Building 32". With the end of that conflict though, they have become less vital, the lead ship has been decommissioned, and their duties parceled out to the more modern units of the Simon Lake-class (AS-33) and L.Y. Spear-class (AS-36) tenders.

Structural/Powerplant

These elderly ships were designed to World War II structural standards, and thus are fairly tough. They are powered by no less than 10 Fairbanks-Morse diesel engines, driving a single shaft with 15,000 SHP.

Weapons

Four Mk 67 20 mm guns.

Countermeasures

None

Sensors

SPS-10 surface search and LN-66 navigation radars.
