The Senegalese Navy has successfully executed its first-ever test launch of an anti-ship missile, marking a pivotal moment in the nation’s transition from a coastal patrol force to a fully capable blue-water navy. The live-fire exercise, conducted from a Walo-class offshore patrol vessel (OPV), demonstrated a new level of operational maturity and deterrence capacity for the West African state.
The test targeted a decommissioned CTM landing craft, which had been retrofitted with shipping containers to simulate a high-value naval target. According to naval officials, the missile struck the target with precision, setting it ablaze, though the vessel remained afloat following the impact.
“This achievement symbolizes the operational maturity of our Navy and its constant commitment to serving national sovereignty,” the Senegalese Navy stated following the exercise.
The Weapon: Marte MK2/N
The weapon employed was the Marte MK2/N, a short-to-medium range anti-ship missile developed by European missile house MBDA. Introduced in January 2006, the MK2/N is the ship-launched variant of the Marte family, specifically designed for littoral and low-intensity naval warfare.
The missile is optimized for engaging fast-maneuvering targets in complex environments. It employs a “fire-and-forget” guidance capability, allowing the launch vessel to disengage or engage other threats immediately after firing. The system relies on mid-course inertial navigation combined with an active radar homing seeker for the terminal phase.
Prior to launch, the ship’s surface search and navigation radars designate the target. Once airborne, the missile flies autonomously through a series of waypoints using its inertial guidance system. As it approaches the target area, the nose-mounted active radio frequency (RF) seeker activates, acquiring the target coordinates and guiding the weapon to impact.
The Marte MK2/N is designed to defeat modern ship defenses through a sea-skimming flight profile, flying just meters above the water to evade enemy radar detection. It delivers a semi-armor-piercing high-explosive (HE) warhead equipped with both impact and proximity fuses, ensuring a high probability of kill against corvettes and fast attack craft. Target designation can also be provided by external platforms, such as helicopters or other vessels, via data link, further extending the engagement envelope.
The Platform: OPV 58 S (Walo Class)
The missile was launched from one of Senegal’s new OPV 58 S vessels, a class of 62-meter combatant ships built by French shipbuilder Piriou. The program, initiated with a contract signing in November 2019, delivered three highly capable vessels to Senegal between 2023 and 2024: the Walo, Niani, and Cayor.
The Walo (delivered June 2023) and its sister ships represent a substantial upgrade in naval firepower for the region. While the contract initially specified a maximum speed of 21 knots, the vessels are optimized for endurance, capable of covering 4,500 nautical miles at a cruising speed of 12 knots. This endurance allows the OPV 58 S to remain at sea for up to 25 days, a critical requirement for patrolling Senegal’s expanding Exclusive Economic Zone (EEZ).
The vessels are heavily armed for their size. In addition to the four forward-mounted Marte MK2/N missiles (providing a strike range exceeding 30 kilometers), the ships field a 76mm Leonardo main gun, two 20mm Nexter remote weapon stations, and 12.7mm heavy machine guns. For air defense, the class utilizes the SIMBAD-RC system armed with Mistral short-range missiles, offering protection against aircraft, helicopters, and drones out to approximately 6 kilometers.
The platform also features a 360-degree panoramic bridge and a modern combat management system (POLARIS), which integrates data from the ship’s sensors to provide a 30-kilometer radius of situational awareness and deterrence.
Propulsion is provided by MAN Energy Solutions, which was contracted to supply MAN 175D diesel engines. These V-type engines (available in 12, 16, or 20 cylinder configurations) allow for efficient operations during long surveillance patrols while providing the necessary power for high-speed interdictions.
Regional Balance of Power
This capability leap aligns with “Naval Strategy 2050,” Senegal’s modernization roadmap aimed at building a strategically autonomous fleet. The timing is critical; Senegal is on the cusp of becoming a major hydrocarbon exporter, with the Greater Tortue Ahmeyim (GTA) gas field and the Sangomar oil field coming online.
Protecting this infrastructure—situated in a maritime zone spanning nearly 200,000 square kilometers—requires robust enforcement capabilities. The region, particularly the Gulf of Guinea, has historically been a hotspot for maritime insecurity, including piracy, armed robbery at sea, and illegal fishing. The ability to deploy credible anti-ship missiles alters the risk calculus for any hostile state or non-state actor operating in these waters.
The successful integration of the Marte MK2/N signals a shift in the West African naval balance of power. Historically, Nigeria held the dominant naval position in the Gulf of Guinea. However, analysts note that while Nigeria’s platforms have faced challenges with maintenance and atrophy over previous years, Senegal has rapidly recapitalized its fleet with modern, missile-armed assets.
With the Walo, Niani, and Cayor now fully operational and combat-proven in testing, the Senegalese Navy has effectively graduated from a constabulary coast guard role to a force capable of conventional naval warfare.
