In this article, we look at the 25 strongest armies in the world in terms of ground forces strength. You can skip our detailed analysis on how countries are racking up their defense capabilities amid military escalation in Ukraine and its impact on the armaments industry by heading over to the 10 Strongest Armies in the World in 2023.
Plenty has unfolded in the last three years. Azerbaijan has seized parts of the Nagorno-Karabakh region from Armenia, Afghanistan has fallen to the Taliban, there are regular border skirmishes between China and India, Russia’s war in Ukraine is nearing 600 days of conflict, and if that was not it, the Middle East has gone up in flames once more with already thousands killed after Palestinian group Hamas’ attack on Israel, which was followed by Tel Aviv ordering aerial strikes on the Gaza strip.
These events have forced several countries, especially those in Europe, to increase their defense spendings to bolster national security. According to figures shared by the Stockholm International Peace Research Institute (SIPRI), global defense spending was estimated to be $2.2 trillion in 2022, with Europe having its steepest rise in 30 years. The United States, China, and Russia account for more than half of all global spending. NATO countries’ defense expenditure was up 0.9% in 2022 year on year, to total $1.2 trillion last year.
The surge in spending has created a boom for armament manufacturers. Lockheed Martin Corporation (NYSE:LMT) generated $66 billion in revenues and net earnings of $5.7 billion in 2022. It is the largest federal defense contractor in the United States, having received over 11% of all DoD spending in 2022, including a $950 million missile order from the Pentagon to refill stockpiles in Ukraine. A number of countries are also equipping their air force with Lockheed Martin Corporation (NYSE:LMT)’s F-35 fifth-generation fighter jet. You can read more on this in our article, Top 16 Defense Contractors in the World in 2023.
This year, the company’s financial performance is even better, as noted by Chairman and CEO, Jim Taiclet, in Lockheed Martin Corporation (NYSE:LMT)’s Q2 2023 Earnings Call:
Our Q2 financial results were strong, with sales of $16.7 billion up 8% year-over-year and double-digit growth at both aeronautics and space. Backlog reached a record level of $158 billion, up $8 billion from year-end resulting from a book-to-bill of $1.7 in the quarter. Orders included an approximately $8 billion option of [Indiscernible] for the 126 F-35 for production lot 17 as well as significant awards to ramp up emissions [Ph] at MSC.
Raytheon Technologies Corporation (NYSE:RTX)’s net earnings rose 8.9% from 2021 to total $14.1 billion in 2022. The armament manufacturer won 6.1% of all defense-related contracts from the DoD during the year, including an order worth nearly $1 billion from the U.S. Air Force to develop scramjet-powered hypersonic cruise missiles.
Revenues of Northrop Grumman Corporation (NYSE:NOC) were also significantly higher in 2022 compared to the previous year. The company is known for its expertise in space and command and control systems. Northrop Grumman Corporation (NYSE:NOC) is also the manufacturer of the strategic bomber B-21 Raider, which is currently under development for use by the U.S. Air Force.
Harding Loevner Global Equity Strategy made the following comment about Northrop Grumman Corporation (NYSE:NOC) in its Q1 2023 investor letter:
Our other purchase was Northrop Grumman Corporation (NYSE:NOC), a US defense contractor whose stock price experienced a pullback. We like that Northrop has a larger presence than its rivals in the most favorable subcategories of the defense industry-namely, nuclear weapons, space systems, and what’s known as C4ISR (which stands for Command, Control, Communications, Computers. Intelligence, Surveillance, and Reconnaissance). C4ISR refers to digital systems that translate data picked up from different sensors-such as an incoming hypersonic missile or advancing troops-into a common format, and then escalate key information to the right people These differentiated technologies are especially relevant in a time of increased geopolitical tensions. Northrop also benefits from large barriers to entry in this stable industry, which should enable continued strong earnings and cash flow.
All being said, recent conflicts have also demonstrated how having large armored, artillery, and infantry units are not enough to gauge a military’s strength. Having an experienced and battle-hardened force, technological advancement in military hardware, and a strong and stable economy are just as important determinants that are often overlooked. Russia, for instance, has the highest number of nuclear weapons, tanks, rocket artillery (MLRS), and self-propelled artillery in the world, and ranks third when it comes to armored fighting vehicles. Despite being a force on paper, it has struggled to find its way in Ukraine in a war that has stretched nearly 600 days with no end in sight.
Methodology
We have ranked the 25 strongest armies in the world by analyzing key metrics pertaining to strength of ground forces, such as active manpower, tanks fleet, armored fighting vehicles, rocket projectors, attack helicopters and nuclear weapons. Collectively, these metrics have been assigned a weight of 50% to determine our rankings. 30% is made up of countries’ military technological capabilities, which is a product of the technological advancement levels of a country coupled with its defense spending. Lastly, we have also considered the sizes of the economies and assigned GDP a 20% weightage. This is a key metric because only a strong economy would be able to sustain a capable ground force over the long run.
