In an era where maritime trade underpins the global economy, mine warfare remains a critical but often overlooked component of naval defence. As key sea routes like the Suez Canal and the Strait of Hormuz continue to facilitate the bulk of international commerce, experts are sounding the alarm over the limited number of countries equipped to counter underwater threats such as naval mines.
Out of 198 countries, only 54 possess a mine warfare fleet, according to data from Global Firepower. Even among these, most maintain only a modest number of mine countermeasure vessels, raising concerns about global preparedness for underwater warfare or post-conflict mine clearance.

Mine warfare fleets are specialised units within a navy, designed to detect, neutralise, and remove naval mines—devices capable of disabling or destroying ships and disrupting vital shipping lanes. In times of conflict, the strategic deployment or removal of mines can significantly impact the outcome of maritime operations. Yet, mine warfare capabilities have not kept pace with broader naval expansions globally.
Nations without adequate mine warfare fleets face heightened vulnerability. In peacetime, they may struggle to prevent the covert laying of mines in territorial waters, while during conflict, they risk blockades or attacks with limited means of response. Furthermore, the absence of mine-clearing capabilities delays recovery after hostilities, endangering lives and slowing the return of commercial shipping.
The post-conflict impact is particularly severe. Countries unable to clear their own waters may be forced to rely on foreign powers or international agencies to remove mines, delaying humanitarian access and maritime traffic for months, even years.

Beyond tactical applications, mine warfare fleets also serve a deterrent function. The ability to deny access to key waterways or coastal areas using sea mines can discourage potential adversaries from launching aggressive actions. When a country lacks this capability, its defensive posture weakens, inviting strategic risks.
As global maritime tensions persist—from the South China Sea to the Gulf of Aden—the gap in mine warfare readiness is a growing concern. For many countries, the absence of even a single mine countermeasure vessel could represent a dangerous blind spot in national security planning.
According to Global Firepower, here are the top 10 countries with the least mine warfare fleets:
1. Yemen – 1 vessel
Yemen’s single mine warfare vessel reflects the country’s ongoing instability. With years of internal conflict and limited resources, its naval capabilities remain minimal. This raises concerns for the security of Red Sea routes, which are essential for global shipping.
2. North Korea – 1 vessel
Despite having a larger conventional navy, North Korea operates only one mine warfare vessel. The country has historically focused on submarines and missile development, with less investment in mine countermeasures.

3. Libya – 1 vessel
Libya maintains just one mine warfare vessel. Ongoing political divisions and civil unrest have left its navy with limited functionality. This situation poses risks to maritime activities along Libya’s Mediterranean coastline.
4. Iran – 1 vessel
Iran, located near one of the world’s most critical chokepoints — the Strait of Hormuz — operates just one dedicated mine warfare vessel. However, the country is known to possess naval mines, which shifts its emphasis from mine clearance to offensive mine-laying capabilities.

5. Croatia – 1 vessel
Croatia, a NATO member along the Adriatic Sea, has one mine warfare vessel. While the region is relatively peaceful, the low number indicates reliance on broader NATO support for undersea security if needed.
6. Uruguay – 2 vessels
Uruguay operates two mine warfare vessels. With limited regional threats and a relatively small coastline, its mine fleet size matches its modest naval priorities.

7. United Arab Emirates – 2 vessels
The UAE, situated near the Strait of Hormuz, has two mine warfare vessels. Given its significant role in global oil exports, this number suggests strategic reliance on allies for additional support in mine countermeasures.
8. South Africa – 2 vessels
South Africa’s navy includes two mine warfare vessels. The country plays a leading role in regional maritime operations around the Cape of Good Hope but keeps a lean mine fleet, possibly relying more on surveillance and partnerships.

9. Nigeria – 2 vessels
Nigeria, located along the Gulf of Guinea, operates two mine warfare vessels. With growing threats from piracy and maritime insecurity, the limited fleet places pressure on Nigeria’s broader naval efforts.
10. Myanmar – 2 vessels
Myanmar’s navy includes two mine warfare vessels. Despite facing internal conflict, the country has not expanded its fleet in this category, focusing more on coastal patrols and riverine operations.
