Faced with refitting a large number of "Frigates" (as known in the CSA), the Navy has elected to convert at least some of them to dedicated flagship/tenders for 10 boat divisions of the new 250t Torpedo Boats.

During conversion, 3/4 of the boilers are removed, reducing top speed, and the rest converted to solely oil firing. The former boiler spaces were used for additional bunkerage and hold space. Most of the 4.85" 55 pounder guns, and all of the 6 pounder guns are removed, their handling rooms being used for additional berthing space. New workshops and berthing was built up on-deck, and space was made for reload torpedo storage. The armored belt was also removed.

Enough fuel is carried to refuel each boat once, and enough torpedoes carried to reload each boat once. The shops are relatively limited, and meant for various light maintenance tasks.

These ships are intended to be used to allow TB divisions to deploy along the CSA coast away from major ports, or for forward deployments elsewhere, though fuel would need to be supplied periodically by oilers.

Events of 1914 revealed that the Confederate Navy's fleet train was woefully inadequate. In a crash program, a large civilian tanker design has been adapted as a new fleet oiler, the Oak class.

Two laid down in 1915:
AO-4 Oak
AO-5 Aspen
