CSS RICHMOND CLASS
Casemated Ironclad.
There are six ships considered to be in this class: Richmond, Savannah, Raleigh, Chicora, Palmetto State and North Carolina.The Thoroughbred kit includes parts to construct one of the first four in this list. The last two are not included due to insufficient information.

USS MIANTONOMOH CLASS OF MONITORS
Double-turreted Monitor.
A total of four ships comprised this class of Union monitors: Miantonomoh, Monadnock, Agamenticus and Tonawanda - akin to the powerful USS Onondaga design. Only one in the class, the Monadnock, actually fired in anger during the Civil War at the bombardment of Confederate Fort Fisher in North Carolina. Her proficient gunnery was noted in several reports on the battle and the subsequent capture of the fort effectively closed the last port available to Confederate blockade runners and led to a quick end of the war as all major supply lines to the outside were now cut. During the last months of the war, Monadnock took part in operations at Charleston harbour - which fell without her assistance, and in the James river as part of the Union fleet before the fall of Richmond.

ELLET UNION RAM
This vessel represents the side wheel rams of  the Union ram fleet created by Army Colonel Charles Ellet Jr. as they first appeared at the battle of Memphis on the Mississippi River in 1862. Those steamers included Lancaster, Queen of the West, Monarch and Switzerland. Switzerland's configuration was later changed by adding an enclosed upper deck with guns.

UNION TINCLADS
Sidewheel Gunboats
The group of gunboats known largely as 'tinclads' consisted primarily of civilian steamers, transports and other special purpose vessels purchased by the government during the war. They were converted for military use on western rivers and waterways. Patrolling river sections, maintaining supply lines, protecting lines of communication, and even taking part in planned combat operations were their main missions. No two were exactly alike due to different dimensions, configurations of cabins, stacks, wheels etc and varying armaments. A large number were stern wheelers. One common characteristic to all was their shallow draft which allowed them to operate in areas where heavier vessels could not go. Generally, bulkheads and flooring were strengthened to withstand the added weight of heavy guns. Extra timber and iron plate - usually one inch thick - were added to protect key areas from enemy small arms fire. Types of guns carried included all calibers from 12 pdr smoothbores up to larger 9" dahlgrens and large-bore rifles.
