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]
