CSS New Orleans was a floating battery fitted out at New Orleans, Louisiana in 1861. The craft featured two small boilers with pump connections for repelling boarders by drenching them with scalding water from her hoses. She was deployed under Lt. S. W. Averett, CSN, in the Mississippi River in time to assist joint army-navy operations at Island Number 10. and New Madrid, Missouri, from 12 March to 7 April 1862. On the final day of the Battle of Island Number Ten, the Confederates, sank the New Orleans.
