Huntsville and the virtually identical Tuscaloosa were small casemate floating batteries laid down at Selma Alabama then converted to self-propelled ironclads. They were initially used at Selma and later, deployed to the defense of Mobile Bay to join CSS Baltic in 1864. There are no existant photos of either vessel, and the few sketches and illustrations vary widely in detail, so there is considerable debate about the actual size of the vessels - estimates range from the 150 or 152 foot length quoted above to nearing 175 feet.

Like most floating batteries later converted to service as ironclads, they suffered from relatively poor sea keeping qualities and were extremely slow, despite motifications to their hulls. The engines installed in both vessels were extremely poor, and sufficient to make about three knots at the best of times, making them unsuitable in their intended role as "ironclad rams." During the Battle of Mobile Bay in August, 1864, both ships were ordered to support CSS Tennessee II in her fight with the Union fleet, and exchanged fire with Union vessels at long range, but did not actually enter the lower bay, probably because the stronger currents in the lower bay may well have reduced them to virtual immobility.

After Mobile Bay, the two remained in the Upper Bay and, with CSS Nashville, defended the city of Mobile in support of its extensive fortifications until the impending fall of the city in April, 1865, caused them to be scuttled to prevent capture in the nearby Spanish River. Their wrecks have been tentatively located, and it is believed that they may be relatively well preserved. The excavation of the wrecks could put to wrest many of the competing theories regarding their deployment, design, and functionality, but it is currently unknown when this might take place.
