Patrol vessel Mangaratiba

Marinha do Brasil recently held the launching ceremony of the patrol vessel “Mangaratiba” (P73) at the Arsenal de Marinha do Rio de Janeiro (AMRJ). Following the ceremony, the vessel will proceed to the next stages, including harbor trials, sea trials, and weapons trials — preceding its commissioning into operational service. Full incorporation into the fleet is expected in the second half of this year.

Construction of the “Mangaratiba” began at a civilian shipyard and was completed at AMRJ, where structural work was finalized and propulsion, electrical, navigation, communication, and weapons systems were installed. Measuring 54.2 meters in length, the vessel has an endurance of approximately 2,500 nautical miles (around 5,000 kilometers) and can accommodate up to 51 personnel, enabling extended operations in remote areas.

What is a patrol vessel?

It is a small- to medium-sized warship, designed for versatility and agility in coastal, riverine, and jurisdictional waters. Its main roles include maritime law enforcement, search and rescue (SAR) operations, combating illicit activities such as illegal fishing and smuggling, and protecting strategic assets such as offshore oil platforms.“

“Mangaratiba” is the fourth patrol vessel of the Macaé class, following:

• NPa Macaé (P70), commissioned in 2009

• NPa Macau (P71), commissioned in 2010

• NPa Maracanã (P72), commissioned in 2022

The next vessel in this series is the patrol vessel “Miramar” (P74), currently under construction, with launch expected around 2028. Keel laying took place in 2024.
