Armament

Like many of the Mississippi theatre ironclads, Cairo had its armament changed over life of the vessel. To expedite the entrance of Cairo into service, she and the other City-class ships were fitted with whatever weapons were available; then had their weapons upgraded as new pieces became available.

 smoothbore cannons were fairly modern most of the other original armaments were antiquated; such as the 32-pounders, or modified; such as the 42-pounder "rifles" which were in fact, old smoothbores that had been gouged out to give them rifling. These 42-pounder weapons were of particular concern to military commanders because they were structurally weaker and more prone to exploding than purpose-built rifled cannons. Additionally, the close confines of riverine combat greatly increased the threat of boarding parties. The 12-pounder howitzer was equipped to address that concern and was not used in regular combat.

Discovery of her wreck

Over the years the gunboat was forgotten and her watery grave was slowly covered by a shroud of silt and sand. Impacted in mud, Cairo became a time capsule in which her priceless artifacts were preserved. Her whereabouts became a matter of speculation as members of the crew had died and local residents were unsure of the location.

, was able to plot the approximate site of the wreck. With the help of a pocket compass and iron bar probes, Bearss and two companions, Don Jacks and Warren Grabau, set out to discover the grave of the Cairo in 1956. The three searchers were reasonably convinced they had found the Cairo, but three years lapsed before divers brought up armored port covers to confirm the find. A heavy accumulation of silt, swift current, and the ever-muddy river deterred the divers as they explored the gunboat. Local enthusiasm and interest began to grow in 1960 with the recovery of the pilothouse, an 8 inch smoothbore cannon, its white oak carriage, and other artifacts well preserved by the Yazoo River

Salvage and museum

Hopes of lifting the ironclad and her cargo of artifacts intact were crushed in October 1964 when the three inch cables being used to lift the Cairo cut deeply into its wooden hull. It then became a question of saving as much of the vessel as possible. A decision was made to cut the Cairo into three sections. By the end of December the battered remains were put on barges and towed to Vicksburg, Mississippi

. Delays in funding the project halted progress until June 1977, when the vessel was transported to the park and partially reconstructed on a concrete foundation near the Vicksburg National Cemetery. A shelter to cover the vessel was completed in October 1980, with the museum opening in November. The original space-frame shelter has recently been replaced by a tension-fabric system to provide better cover.

The recovery of artifacts from Cairo revealed a treasure trove of weapons, munitions, naval stores, and personal gear of the sailors who served on board. The gunboat and its artifacts can now be seen along the tour road at the USS Cairo Museum. These even include a sailor's rope knife in very good condition, as reported in Knives and their Values, 4th edition by Bernard Levine.

The USS Cairo has been degrading since been exposed to the elements, bird droppings, and vandals who have grabbed a piece of her hull.
