After America, Which NATO Country Has the Strongest Military Power?

Among NATO nations, military strength has increasingly become indicative of ambition on the world stage with the United States, United Kingdom, and France leading the charge as the most powerful actors within the alliance. At the same time, maintaining these formidable forces requires sustained investment which in turn fuels different sectors of their economies, ranging from defense to tech. Here, 24/7 Wall St. is taking a closer look at the strongest military powers within the NATO alliance.

To determine the NATO countries with the strongest military might, 24/7 Wall St. reviewed the 2025 Military Strength Ranking from Global Firepower, an annually updated defense-related statistics website with information on 145 countries. Global Firepower ranked 145 countries based on their PowerIndex, a composite of over 60 measures in categories such as military might, financials, logistical capability, and geography. The smaller the PowerIndex value the more powerful a nation’s theoretical conventional fighting capability is. We ranked these countries according to their PowerIndex score. We included supplemental information regarding active military personnel, military aircraft, vehicles, and naval power, as well as the defense budget.

Here is a look at the strongest military powers in NATO:

Why Are We Covering This?

Understanding NATO’s military dynamics is important when looking at the state of global security. Since its inception, NATO has played a pivotal role in shaping international relations through its collective defense and security framework. As geopolitical tensions continue to rise and new threats emerge, knowing and understanding NATO’s military capabilities is important for getting a clearer picture of the world stage. Not to mention, countries like the United States, the United Kingdom, and Germany, among others, contribute significantly to NATO’s military strength, influencing global power balances and regional stability.
