There were several dozen, maybe twice as many in the Union Navy as in the Confederate. But the two most famous were among the very first, and fought each other in 1862, revolutionizing naval warfare for all nations. This is remembered as the Monitor versus the Merrimac. The USS Monitor was the northern ship, and the other was the CSS Virginia. The Virginia was built on the remains of the old USS Merrimac, a ship burned by the Union Navy when they had to abandon the Norfolk Navy Yard. But Monitor versus Merrimac sounds better than Monitor versus Virginia, so that's how newspapers reported it.
