For maritime security, a domain that often flies under the radar, Africa is quietly redefining its economic growth or diplomatic influence. With vast coastal territories teeming with resources and increasing geopolitical stakes, the continent is taking bold strides to strengthen its naval capabilities with the growing adoption of submarines.
Once considered exclusive to the world’s most advanced militaries, submarines are now emerging as essential tools in Africa’s maritime arsenal. Why the shift? The answer lies in the continent’s extensive coastline and critical maritime assets, which demand protection in an era of growing instability. Submarines, with their ability to operate unseen beneath the waves, offer a formidable means to secure national interests.

Egypt leads the charge with eight submarines, followed by Algeria with six and South Africa with three, according to Global Firepower in 2025. These figures may seem modest by global standards, yet their impact on regional security is profound. Submarines bolster territorial sovereignty in disputed waters, deter external aggressors, and ensure that nations have a silent but potent presence beneath contested seas.
As Africa’s role in global trade and resource management continues to expand, the stakes in securing its maritime corridors grow ever higher. Submarines not only safeguard fisheries, hydrocarbons, and shipping routes but also send a powerful message to potential adversaries: Africa is no longer an easy target.
Submarines, equipped with advanced sonar and weaponry, are a game changer. They provide unparalleled surveillance and can respond to threats that might otherwise go undetected. Yet their role isn’t confined to defence. Submarines have a quieter but equally critical function: supporting humanitarian missions. Whether conducting search-and-rescue operations, monitoring environmental changes, or aiding disaster relief efforts, they demonstrate versatility that goes beyond warfare. In this dual role, submarines offer African nations a unique opportunity to assert both strength and compassion on the international stage.
Solutions for Enhanced Maritime Security
The answers lie in collaboration and innovation. Regional cooperation, driven by frameworks like the African Union’s Agenda 2063, can pool resources and intelligence, allowing nations to mount a united response to shared threats. Partnerships with established naval powers offer access to training and technology, bridging capability gaps.
Equally critical is the modernisation of maritime infrastructure. Upgrading ports and building maintenance facilities will ensure that Africa’s submarines can remain operational and effective. But perhaps the most transformative solution lies in adopting comprehensive maritime policies—strategies that integrate military, economic, and environmental priorities into a cohesive vision.
Collaboration with global institutions, such as the United Nations and regional maritime security bodies, can unlock funding and resources, further empowering Africa to navigate these uncharted waters.
A Watershed Moment for Africa
Africa stands on the brink of a maritime revolution. The rise of submarines within its naval strategy signals not just a commitment to defending its vast coastal wealth but a bold statement of intent on the global stage. How this journey unfolds will depend on the continent’s ability to address challenges, harness regional unity, and embrace innovation.
The implications are profound. By securing its seas, Africa is not only safeguarding its resources but also shaping the future of global maritime stability. The oceans hold the keys to trade, energy, and food security—and with submarines beneath the waves, African nations are proving they are ready to unlock that potential.
