The Inhaúma Class corvettes are five escort vessels operated by the Brazilian Navy. They were named after Joaquim José Inácio, Viscount of Inhaúma. These ships were built in Brazil and designed with assistance from the German company Marine Technik. It was originally planned to build 12 to 16 ships but the economic situation in Brazil did not permit this and only five vessels were built. The programme was considerably delayed due to funding issues and the Brazilian Verolme yard's insolvency in 1991 which forced V32 and V33 to be completed by Arsenal da Marinha.
The ships were fitted with a Ferranti CAAIS 450 (Computer Aided Action Information System) combat data system and a SAAB EOS-400 fire control system. Further vessels were planned to have indigenous Brazilian missiles but this was shelved. Conway's reports the ships as being top-heavy.
All ships were completed by the Arsenal da Marinha, Rio de Janeiro, and three are currently (2016) in service.
