Russia’s invasion of Ukraine has sent shockwaves across Europe. With war returning to the continent after decades of peace, several countries in the region are aggressively racking up their defense to enhance national security. Global defense expenditure reached a record-high of $2.2 trillion in 2022, with Europe seeing its steepest rise in 30 years having incurred $480 billion on military spending that year.

According to a recent report by the Stockholm International Peace Research Institute (SIPRI), there has been a 94% increase in arms imported by Europe between 2019-2023, compared to 2014-2018, with 55% of the equipment imported in the last five years coming from the United States. The surge in military spending has created a boom in the global defense industry, where output is being increased at a rapid rate to meet growing demand for weapons.

General Dynamics Corporation (NYSE:GD) has increased its production of artillery from 14,000 to 20,000 rounds per month. The company has benefited from the military assistance offered by the United States for Ukraine, which has included the 155 millimeter artillery replacements that have been pivotal to Kyiv’s fightback against Russian advancements. General Dynamics Corporation (NYSE:GD) generated $42.3 billion in revenues in 2023 – its highest ever, with a 7.7% year-over-year growth. 

Phebe Novakovic, the CEO of General Dynamics Corporation (NYSE:GD) shared the following remarks in the company’s Q4 2023 Earnings Call: 

On the other hand, the production of artillery shells has also soared in Russia, having increased nearly 2.5 times in 2023 compared to the preceding year, as Moscow looks to arm itself faster than the west replenishes Ukraine. According to a report, the Russians are producing thrice the amount of artillery munition as all of Europe and the United States combined.

Lockheed Martin Corporation (NYSE:LMT) also stated in February this year that it was on track to increase its output of the High Mobility Artillery Rocket Systems (HIMARS) in 2024 to 96 per year, from the current production level of 60. The United States has so far donated 39 HIMARS to Ukraine since 2022, which are now one of the country’s finest weapons being used to push back Russia. After two years of trying, in March this year, the Russians were finally able to destroy one HIMARS in operation of Kyiv.

Seeing the success of HIMARS in Ukraine, several European countries are also looking to buy the rocket artillery system, or develop their own. According to a report, Germany’s Rheinmetall has partnered with Lockheed Martin Corporation (NYSE:LMT) to build GMARS, which would be similar to but larger than HIMARS. Last year in February, Washington approved the sale of HIMARS, ATACMS, and other ammunition worth $10 billion to Poland. Lithuania is also purchasing eight M142 HIMARS from Lockheed Martin Corporation (NYSE:LMT) for $495 million, as part of an agreement reached in late 2022.

Methodology

Artillery strength by country has been determined by considering the total number of artillery units operated by countries, which comprise self-propelled artillery, towed artillery, and rocket projectors. We also factored in technological capabilities of countries to even out countries that have fewer, more advanced artillery and those with large but outdated inventories. Total artillery units were weighed at 80%, while technological capabilities at 20%.

Data has been sourced from our recent articles 25 Countries with the Strongest Armies in the World and 24 Most Powerful Militaries in the World in 2024, along with the Global Firepower Index 2024 and WIPO's Global Innovation Index 2023.

Only countries that have more than 500 artillery units were considered for this list. We observed where each country that met the criteria ranked compared to others and assigned them a score. For instance, if a country ranked second out of 36, it received a score of 0.97 for the total artillery units metric (35/36). For technological capabilities, 132 countries are ranked in the Global Innovation Index. Here, countries' global ranks were divided by 132 to determine their scores for this metric. Finally, scores for both metrics were averaged to get an average score.  The top 20 countries by artillery strength are listed in ascending order of their average scores.
