Macaé-class patrol vessel:

Macaé-class is a series of offshore patrol vessels (OPVs) being constructed for the Brazilian Navy. The vessels will patrol Brazilian Jurisdictional Waters (AJB).

The Macaé-class vessels are being built under a five-ship acquisition programme launched by the government of Brazil in 2006, but the construction was interrupted after the first ship named Macaé.

The Macaé-class patrolling vessels are based on the French CMN Vigilante 400 CL54 platform. Its proven design incorporates a round bilge hull for high stability in rough seas. The hull is made of steel, while the superstructure of the OPV is built using aluminium. The modular design further enables the integration of subsystems for multiple applications.

The stern side of the ship is equipped with a dedicated A-frame davit to launch and recover two rigid-hull inflatable boats (RHIBs). The patrol vessel has a displacement of 500t and will be able to accommodate a crew of 49 members.

The OPV measures 55.2m-long and 8m-wide, while the depth and draft of the vessel are 4.6m and 2.3m respectively.

The Macaé-class patrol vessels are armed with a 40mm cannon and two 20mm guns. BAE Systems is responsible for manufacturing and delivering Bofors 40 Mk4 naval guns for the vessels.

The patrol vessels are powered by two MTU Friedrichshafen 16V 4000 M90 diesel engines coupled to a pair of controllable pitch propellers. The ship’s propulsion also integrates two main generator sets and an emergency generator to power the onboard systems.

The vessels can reach up to of 21k speed and attain a range of more than 4,600km at 15k speed.
