However, several nations on the continent have outdated, small, or inadequately armed navy fleets; some have none at all.
Weak naval strength immediately affects trade, revenue protection, and sovereignty, in addition to defense issues.

In a time when more than 90% of Africa’s trade is conducted by sea, the lack of a reliable naval force exposes nations to dangers that could subtly but seriously impede national progress.
One of the most obvious consequences of insufficient naval strength is the inability to adequately patrol territorial waterways. This provides fertile ground for piracy, armed robbery at sea, and illegal commerce.
The Gulf of Guinea, long the world’s piracy hub, highlighted how inadequate naval patrols allowed criminal networks to thrive, raising insurance costs and inhibiting marine trade.
When ships perceive coastal waters as hazardous, shipping costs rise, port calls decrease, and trade competitiveness declines.
For export-dependent African economies, a loss of trust directly translates into fewer revenues and slower economic progress.

A visible representation of maritime sovereignty is a navy.
A nation is obviously vulnerable when it is unable to maintain control over its Exclusive Economic Zone (EEZ).
Weak naval capabilities make it possible for foreign warships or criminal organizations to operate in national seas without consequence.
A nation’s authority and bargaining power in regional marine issues are weakened by this erosion of sovereignty.
Over time, it also makes it more difficult to police immigration restrictions, customs laws, and environmental laws along coastal borders.

Furthermore, many African countries rely substantially on offshore oil and gas facilities, underwater cables, and port infrastructure.
Any disruption in offshore energy production can have severe fiscal ramifications, especially in countries where hydrocarbons account for a major portion of government revenue.
Without proper naval security, these assets become valuable targets in increasingly contested maritime environments.
With that said, here are the African countries with the weakest naval fleets, with at least one naval fleet, at the end of 2025, according to Global Firepower.
