USS Tahoma
The Unadilla class was a class of gunboat built for the Union Navy at the outbreak of the American Civil War. Ships of the class were also known as "90-day gunboats" due to their rapid construction. The class was designed to be fully oceangoing while having a light enough draft to be able to operate close inshore, for blockade duty or other operations in shallow waters.
