In a decisive move to recalibrate regional maritime security and safeguard global energy supply lines, Saudi Arabia has formally announced the establishment of a multinational maritime defence coalition spanning the Red Sea, the Bab el-Mandeb Strait and the Gulf of Aden. Unveiled by the Saudi Ministry of Defence, the alliance unites eight littoral states across the Middle East and Africa in response to escalating maritime security threats and structural shipping disruptions that have rattled international trade.
The coalition brings together a strategically vital lineup of Asian and African coastal states: Saudi Arabia, Jordan and Yemen from the Arabian Peninsula, alongside Egypt, Sudan, Djibouti, Eritrea and Somalia from the African continent. Together, these countries command the entirety of the Red Sea littoral, controlling critical entry and exit points to one of the world’s most vital maritime corridors—carrying approximately 12% of global trade and serving as a lifeline for crude oil, liquefied natural gas (LNG) and containerized freight between Europe, Asia and Africa.
According to an official statement from the Saudi Ministry of Defence, the coalition’s operational mandate is built around three core pillars. First, it aims to protect international maritime corridors against state and non-state threat vectors. Second, it focuses on ensuring the security of commercial and energy transit routes traversing the Red Sea and Gulf of Aden. Third, it seeks to strengthen collective defence cooperation, joint naval readiness and intelligence-sharing among member armed forces.
“The coalition is designed to protect international maritime corridors, ensure the security of commercial and energy routes, and strengthen collective maritime defence cooperation across the Red Sea, Bab el-Mandeb Strait, and Gulf of Aden.”
The coalition emerges against the backdrop of acute insecurity in the Red Sea. Months of persistent drone, missile and hijacking attacks on commercial vessels tied to wider regional conflicts—involving the United States, Iran, Israel and regional armed groups—have turned the waterway into a high-risk operational zone. This instability has forced major global shipping lines to bypass the Suez Canal and reroute container ships around Africa’s Cape of Good Hope. The detour adds up to 14 days in transit, inflates fuel and insurance premiums and severely disrupts supply chains serving European, Asian and African markets.
Each member nation holds a key strategic position along this critical maritime grid. Saudi Arabia acts as the primary coalition lead, leveraging its expansive Red Sea coastline, deep-water port infrastructure and naval power. Egypt controls the northern gateway via the Suez Canal, a vital national currency earner and global transit hub. Jordan provides northern Gulf of Aqaba security and critical logistics linkages. Djibouti controls the western shore of the Bab el-Mandeb bottleneck while hosting major international naval bases. Eritrea overlooks primary Bab el-Mandeb shipping lanes and southern Red Sea access routes. Somalia commands an extensive Gulf of Aden and Indian Ocean coastline crucial for anti-piracy operations. Sudan brings a long central Red Sea coastline that acts as a strategic bridge connecting North and East African trade networks. Finally, Yemen controls the eastern shoreline of the Bab el-Mandeb Strait and its southern approaches.
For the five participating African nations—Egypt, Sudan, Djibouti, Eritrea and Somalia—the coalition is far more than a symbolic military alliance. The Bab el-Mandeb Strait represents an indispensable economic neck, where any blockade or elevated threat level immediately impacts African import costs, export competitiveness and food security. For Egypt in particular, southern Red Sea security is directly linked to sovereign revenue, as diverted traffic away from the Suez Canal has significantly curtailed canal toll receipts, reinforcing Cairo’s interest in stabilizing the southern approach.
Beyond high-intensity conflict mitigation, enhanced multilateral naval patrols and intelligence-sharing offer immediate practical benefits for Horn of Africa nations targeting persistent security challenges. These joint efforts focus on deterring a resurgence of maritime piracy networks in the Gulf of Aden, cutting off illicit arms trafficking routes and human smuggling networks operating across the Bab el-Mandeb, and safeguarding African Exclusive Economic Zones (EEZs) against illegal, unreported and unregulated (IUU) fishing.
This initiative underscores Saudi Arabia’s broader transition into a proactive regional security architect. Under its Vision 2030 framework, Riyadh has invested heavily in modernizing its naval fleet, building out Red Sea logistics hubs and establishing bilateral defence agreements across East Africa. By spearheading an 8-nation alliance of littoral states, Saudi Arabia aims to establish a regionally owned security matrix capable of safeguarding global trade choke points while reducing sole reliance on external superpower naval deployments.
