The Nigerian Navy has achieved a key milestone in its modernization journey as its second OPV-76 class offshore patrol vessel, P204, successfully completed sea trials.
Built by Turkey’s DEARSAN Shipyard, the vessel demonstrated its advanced capabilities by reaching an impressive speed of approximately 30 knots during testing. This achievement part of the Nigerian Navy’s commitment to enhancing its maritime security and operational readiness, particularly in the Gulf of Guinea, a region increasingly challenged by piracy and illegal activities.
The OPV-76 program is the result of a strategic partnership between Nigeria and Turkey, aimed at bolstering Nigeria’s maritime defense capabilities. The procurement process began in August 2021, culminating in a contract signed on November 3, 2021, with the approval of then-President Muhammadu Buhari. The total project cost stands at $160 million, with an initial payment of $35 million made in June 2022.
Construction officially commenced with a keel-laying ceremony on September 16, 2022, and the project is on track for completion within 37 months.
The first vessel in the series, P203, was launched on October 26, 2023, followed by P204 on April 19, 2024. Both ships are scheduled for delivery to the Nigerian Navy in 2025, marking a significant step in the Navy’s modernization efforts.
The OPV-76 class ships are designed to perform a wide range of missions, including: Maritime patrol, Surveillance, Counter-smuggling, Search and rescue, and Special forces operations.
Their modular structure allows for the integration of additional sensors and weapons systems, ensuring adaptability to evolving operational needs. During peacetime, these vessels will play a critical role in safeguarding Nigeria’s maritime domain and curbing illegal activities in the Gulf of Guinea.

Key specifications of the OPV-76 include:
- Length: 76.8 meters
- Width: 11 meters
- Displacement: 1,200 tons
- Operational range: 3,000 nautical miles
- Hull material: Steel
- Superstructure material: Sealium
- Flight deck: Capable of accommodating medium-sized helicopters (no hangar)
This combination of speed, range, and flexibility makes the OPV-76 an ideal platform for the Nigerian Navy’s diverse operational requirements.
Enhancing Regional Security and Defence Cooperation
The successful sea trials of P204 not only highlight the vessel’s technical prowess but also reinforce the growing defense cooperation between Nigeria and Turkey. As the Nigerian Navy prepares to take delivery of both OPV-76 vessels in 2025, this program is set to significantly enhance the country’s ability to secure its waters and contribute to regional stability.
In an era where maritime threats are becoming more sophisticated, the OPV-76 class represents a forward-looking investment in Nigeria’s defense infrastructure.
In addition to the OPV-76 project, Dearsan Shipyard is involved in the refit of Nigeria’s flagship vessel, the NNS ARADU (F89) frigate, and the construction of a 57-meter Tuzla-class patrol boat. The NNS ARADU, built in Germany, is undergoing upgrades at Dearsan’s facility in Tuzla, Istanbul. The Tuzla-class patrol boat, already in service with the Turkish and Turkmen navies, is expected to improve Nigeria’s coastal security. Nigerian Navy personnel are also receiving training in Türkiye on the Abramak IP-based integrated communication system, which will be installed on the OPV-76 vessels.
