25 Most Powerful Countries in the World by Military

In this article, we look at the 25 most powerful countries in the world by military. You can skip our detailed analysis on countries racking up their defense capabilities and its impact on the armaments manufacturing industry by directly heading over to our list of the 10 Most Powerful Countries In The World By Military.

The last three years have been marred by conflict, with no end in sight. Russia’s war in Ukraine has been ongoing for the last 650 days with scores dead and millions displaced. There are regular border skirmishes in the Caucasus between Azerbaijan and Armenia, with the former having seized parts of the Nagorno-Karabakh region from Armenian control during the fall of 2020. Afghanistan’s collapse to the Taliban in 2021 has also created a security challenge for regional countries. Worst of all, the Middle East is up in flames after Israel invaded the Gaza strip following hundreds of Hamas fighters launching an attack on Israel last month.

Driven by security challenges, several nations of the world are increasing defense spending to equip their militaries with advanced, sophisticated weapons required to enhance their capabilities. Global defense spending reached a record high of $2.2 trillion in 2022, according to the Stockholm International Peace Research Institute (SIPRI), with Europe having its steepest rise in expenditure in 30 years. The United States, China, and Russia accounted for more than half of all military spending that year, while defense expenditure of NATO member countries rose 0.9% to total $1.2 trillion.

The uptick in defense expenditure has meant a boom for the global defense industry. Lockheed Martin Corporation (NYSE:LMT) posted revenues of a whopping $66 billion in 2022, and earned $5.7 billion in profits. The company is the largest defense contractor in the US and received 11% of all DoD military-related contracts last year. RTX Corporation (NYSE:RTX) also reported an 8.9% increase in its net earnings compared to 2021. Northrop Grumman Corporation (NYSE:NOC)’s sales were also significantly higher in 2022 compared to the previous year.

The United States continues to retain its aerial and naval superiority over both China and Russia because of its fleet of the fifth-generation fighter jets and advanced aircraft carriers, including a $13.3 billion warship. In 2005, Lockheed Martin Corporation (NYSE:LMT)’s F-22 Raptor enabled the United States to become the first country to have a fifth-generation fighter jet. Later in 2015, Lockheed Martin Corporation (NYSE:LMT) developed the F-35B Lightning II to give the US Air Force a further edge over its rivals in aerial space.

What separates fifth-generation fighter jets from the previous generation of jets is that these are equipped with modern technologies of the 21st century such as “stealth” and come equipped with features that make it hard for radars to detect them. Russia, with its Su-57, and China with J-20, have their own versions of fifth-generation stealth fighter jets but lag behind the Americans in both fleet size and capabilities.

On the naval side of things, the United States has the highest number of aircraft carriers. Currently, the US Navy is working with Huntington Ingalls Industries, Inc. (NYSE:HII) on the development of nuclear-powered Gerald R. Ford class aircraft carriers that would replace the Nimitz class aircraft carrier design. The Navy plans on having at least four of these carriers.

The first of these, CVN-78, has already been delivered by Newport News Shipbuilding, a division of Huntington Ingalls Industries, Inc. (NYSE:HII). The carrier was first procured in 2008 for an estimated $13.3 billion. It was commissioned in 2017, and became operational in 2021. The scheduled delivery years for the remaining three carriers – CVN-79, CVN-80 and CVN-81 – are 2025, 2028 and 2032, respectively.

There is a key military frontier, however, in which Russia is ahead. That is hypersonic missiles. These missiles evade radars and travel at a speed of over 6,200 km per hour in the upper atmosphere, which is five times more than the speed of sound. The first type of hypersonic missile is the Hypersonic Glide Vehicle (HGV), which has the ability to leave and plunge back into the Earth’s atmosphere. The other, which is the Hypersonic Cruise Missile (HCM), is capable of carrying nuclear warheads and travels at a lightning speed at lower altitude. The exact count of the hypersonic missiles Russia possesses is not known. The Americans are currently pursuing development of these weapons. The U.S. Department of Defense set aside $3.2 billion in 2021 in R&D for hypersonic missiles, according to the DoD.

All being said, recent conflicts have demonstrated that just having a military that is large in size and units of inventory alone is not enough to gauge its strength. The professionalism, skill level and battle hardness of troops, and being in possession of advanced, sophisticated equipment instead of decades-old outdated technology are often ignored, but these are critical determinants of military power. Logistics, geographical reach, and space presence are other important factors in today’s world. Nuclear deterrence is another key competitive edge that some nations hold over the others. Therefore, all of these factors must be weighed in when determining military strength.

Methodology

We have considered ten weighted metrics to rank the most powerful countries in the world by military. These metrics and their weights are as follows: GDP 5%, defense spending 10%, tanks 10%, manpower 10%, nuclear weapons 15%, military aircraft including fighter jets 15%, naval assets 15%, technological capabilities 5%, military satellites 5%, active airfields 5%, and overseas military bases 5%.

We referred to 50 Largest Economies in the World in 2023 for data on GDP, while SIPRI’s 2023 report was used for figures related to military spending by countries in 2022. Information related to manpower, tanks, and military satellites was pulled from our recent articles, 25 Strongest Armies in the World in 2023 and 15 Countries with the Highest Number of Military Satellites in Orbit. For number of nuclear weapons, military satellites and overseas military bases, our source was The Power Atlas. Global Innovation Index 2022 was used to gauge technological capabilities of each of these countries. Information related to fighter jets and naval assets were taken from Global Firepower Index 2023 and Flight International 2022.

Weighted scores for each metric were then aggregated to get an overall score. The most powerful countries in the world by military strength are ranked in ascending order of those scores.

Let’s now head over to the list of the world’s most powerful countries by military.

Kyiv’s defense capabilities have been enhanced by the military and financial support it has received from the United States and its European allies. HIMARS made by Lockheed Martin Corporation (NYSE:LMT) have been instrumental in pushing Russia back as they allowed Ukraine to strike Russian targets with precision. Last year, the Biden administration gave $631 million worth of these to Ukraine. During the same year, RTX Corporation (NYSE:RTX) was awarded a $624 million contract to provide Kyiv 1,300 stinger missiles, while the US in January this year announced to send 31 M1 Abrams built by General Dynamics Corporation (NYSE:GD) in fresh military assistance to Ukraine.
