Brazil Commences Construction of 11 New NPa500MB Offshore Patrol Vessels

Brazil has initiated the construction of 11 NPa500MB offshore patrol vessels under the Patrol Vessel Acquisition Program (PRONAPA). This program aims to enhance maritime security and operational capabilities. The project is allocated 2.8 billion reais and includes advanced weaponry and technology. A cooperation agreement has been established to facilitate effective design and construction processes.
The Brazilian Navy has commenced the construction of 11 new NPa500MB offshore patrol vessels (OPVs) as part of its Patrol Vessel Acquisition Program (PRONAPA). The Naval Systems Design Center (CPSN) delivered the basic engineering plan to Emgepron in late January 2025. These 500-ton vessels will primarily serve to monitor the Exclusive Economic Zone (EEZ), conduct search and rescue operations, and combat illegal activities such as fishing.
The projected cost for acquiring eight NPa500MB vessels is estimated at 2.8 billion reais (approximately 476 million USD). Emgepron, a state-owned entity, anticipates three of these vessels will be configured specifically for mine countermeasures operations. The initial construction budget for the first unit is set at 250 million reais (around 42.5 million USD).
The NPa500MB design is included in Brazil’s Growth Acceleration Program, emphasizing its importance to national interests. Emgepron is exploring marketing opportunities for the vessel to allied nations in regions like South America, Africa, and Asia. The government’s Multi-Year Plan allocates 5.26 billion reais (approximately 894.2 million USD) for ongoing support until 2035.
Key specifications of the NPa500MB include a length of 58.9 meters, a beam of 9.0 meters, and a maximum draft of 2.5 meters, with a displacement of 564 tons when fully loaded. The vessel is equipped with advanced weaponry and technology, including a Bofors Mk4 40 mm gun and integrated navigation systems, ensuring successful long-duration patrol effectiveness.
A technical cooperation agreement signed in November 2023 between the Brazilian Navy and Emgepron underscores their commitment to advancing engineering designs and shipbuilding capabilities for these vessels. The production schedule anticipates the completion of the first vessel by 2025, enhancing Brazil’s maritime security and its engagement in international security endeavors.
Currently, the Brazilian Navy operates a fleet of 22 offshore patrol vessels across various classes. Future acquisitions will supplement existing classes and maintain operational readiness, ensuring robust maritime security management.
In summary, Brazil’s commitment to enhancing its naval capabilities is exemplified by the construction of the NPa500MB offshore patrol vessels. This strategic initiative promotes domestic manufacturing, aims to bolster maritime security, and supports international collaborations. With a phased delivery schedule and significant financial backing, the initiative represents a significant step forward in Brazil’s naval modernization efforts.
