The Mariz e Barros-class ironclads were a pair of armored corvettes originally ordered by Paraguay in 1864, but were sold to Brazil when Paraguay defaulted on the payments. Configured as central-battery ironclads, they served during the 1864–1870 Paraguayan War between Brazil, Argentina and Uruguay against Paraguay. Herval was scrapped in 1879 while Mariz e Barros was converted into a floating battery in 1884 and scrapped in 1897.
