The Macaé class are a series of offshore patrol vessels being built for the Brazilian Navy by Arsenal de Marinha do Rio de Janeiro.

History

The class was based on the CMN Vigilante 400 CL54 design.^[3] The first two Macaé-class ships were built by INACE, following a 2006 contract. It was delivered in 2012, while the second ship was delivered in 2010.^[4]

The construction of Maracanã and Mangaratiba was halted in the mid-2010s, and restarted in the early 2020s. The laid down of Miramar took place in November 2024.^[5]
