Inscription. Meet the deadline or pay $200 a day. James Eads had agreed to these terms for the construction of seven new ironclads. To speed production, a partner shipyard built three of the boats, including the one in front of you. Eads' shipyard built the other four boats. All seven boats were delivered 100 days later.

The USS Cairo and her six sister boats were all named for towns along the Ohio and Mississippi Rivers. Unlike wooden sailing ships used at the beginning of the Civil War, these new ironclads had steam driven engines, armor plating, 13 cannon, and a top speed of nine miles per hour.
