Macaé (FRA Vigilante)

The CMN Vigilante class patrol craft are versatile vessels designed for maritime surveillance, interdiction, and search and rescue operations. They are characterized by their robust steel hull and aluminum superstructure, offering good seakeeping capabilities and adaptability for various weapon systems.

Developed by the French shipyard Constructions Mécaniques de Normandie (CMN) under the Vigilante 400 CL54 design, the Macaé-class was ordered by the Brazilian Navy to modernize its offshore patrol fleet and secure its vast "Blue Amazon" maritime economic zone. The lead vessel, Macaé, was constructed in Brazil through a technology transfer agreement and officially entered service in December 2009. Throughout their operational history, these vessels have been actively deployed for sovereignty patrols, fishery protection, and joint regional security exercises along the South Atlantic coast. The class remains in active service today, serving as a cornerstone of Brazil's coastal defense and demonstrating the successful adaptation of French naval architecture for South American maritime security needs.
