Global Defense Spending

Figures released this April by the Stockholm International Peace Research Institute (SIPRI) estimated global defense spending for 2023 at a record high of $2.44 trillion, having risen 6.8% compared to the previous year. This is the biggest spike in military expenditure since 2009 and the ninth successive year defense spending had increased.

With defense bills worth a whopping $916 billion during the year, the United States accounted for 37.5% of the world’s total military spending in 2023. The figure was 2.3% higher than last year and represented more than two-thirds (68%) of NATO’s overall defense expenditure in 2023. $588 billion was spent in Europe, which was 16% higher than in 2022, and made up 24% of the global spending. The spike was triggered by a substantial increase in defense spending by both Russia and Ukraine, while several other countries in the region also bolstered their defenses with war returning to the continent after decades of peace.

Asia incurred $560 billion on defense in 2023. The figure was 40% more than what it was a decade ago in 2014. A major chunk of this expenditure came from East Asia and South Asia, while oil-rich monarchies in the Middle East also spent hefty amounts on strengthening their national security.

The surge in defense spending over the last two years, specifically after Russia’s invasion of Ukraine in February 2022 has created a boom in the global defense industry. The ongoing conflict in the Middle East involving Israel and Hamas has further bolstered their finances. Lockheed Martin Corporation (NYSE:LMT) posted a revenue of $67.6 billion in 2023, representing a 2.4% increase year-over-year. The company’s earnings also grew $1.2 billion compared to 2023.

Since the beginning of the Russia-Ukraine conflict, Lockheed Martin Corporation (NYSE:LMT)’s share price has gained 29%, due to strong demand for its weapons, especially HIMARS, GMLRS, and the F-35 fifth-generation fighter jet. The stock is projected for further growth with no end in sight to the war in Europe and the aggravating situation in the Middle East. In April this year, the United States announced $95 billion in fresh military aid for Ukraine, Israel, and Taiwan. Experts believe a major chunk of this amount is going to go into the procurement of advanced weapons from companies such as Lockheed Martin Corporation (NYSE:LMT). It is one of the best aerospace and defense stocks to buy now, with 47 hedge funds bullish about the company’s prospects in Q1 2024, according to Insider Monkey.

RTX Corporation (NYSE:RTX) is another stock that is flying high amid strong financial results. After a solid 2023, during which it posted nearly $69 billion in revenue, the company had a robust first quarter of 2024 as well, with sales totaling $19.3 billion and registering a 12% YoY growth. Its earnings per share of $1.34 was also 10% higher than in the first quarter of last year. RTX Corporation (NYSE:RTX)’s share price has spiked 15% since the start of the Ukraine war in early 2022.

Anticipating a sustained demand for its weapons, RTX Corporation (NYSE:RTX) expects total revenue between $78-99 billion for FY 2024 and an EPS in the range of $5.25 – $5.40. According to Insider Monkey’s hedge funds database, 62 hedge funds are bullish on the company. Their optimism stems from RTX Corporation (NYSE:RTX)’s impressive backlog of $196 billion, of which $78 billion is related to defense orders, including a $2.8 billion guided-missile order by NATO.

Methodology

We considered 14 weighted metrics to rank 15 countries that have the best military in the world. These include GDP and defense spending (20%), technological capabilities (15%), manpower and special forces strength (15%), nuclear weapons (10%), aircraft including fighter jets (10%), aircraft carriers and submarines (10%), tanks and artillery (5%), military satellites in orbit (5%), overseas military bases (5%), and cybersecurity capabilities (5%). It was seen where each country ranked on a given metric and then was assigned a weighted score accordingly. Finally, all weighted scores were aggregated to get an overall score. Countries with the best military in the world are ranked in ascending order of their overall weighted scores.

Data on GDP was sourced from the IMF, while SIPRI was consulted for numbers related to defense spending. For other military-related metrics, we referred to our recent articles such as 20 Largest Air Forces in the World Heading into 2024, 15 Countries with the Most Battle Tanks in the World, Artillery Strength by Country: Top 20 Militaries, amongst others; the Global Firepower Index 2024; and Power Atlas.
