L.Y. Spear-class

Designed to support nuclear attack submarine operations, these ships are the last such ships built for the US Navy. They can service up to 12 submarines at a time, with up to four alongside at once. In addition to hospital facilities, machine shops, and a helicopter pad, they have a large submarine weapons stowage capacity. This includes magazines for torpedoes, as well as Harpoon and Tomahawk missiles. Good ships for the job, though a sitting duck tactically.

Structural/Powerplant

A follow-on to the earlier Hunley-class (AS-31) tenders, the L Y Spear-class vessels are different only in minor structural details and the propulsion. These are powered by a pair of Combustion Engineering oil-fired boilers feeding a set of LaVal steam turbines. These power a single shaft delivering 20,000 SHP.

Four Mk 67 20 mm guns.
