In This Article:

In this article, we take a look at 12 biggest militaries in the world and whether or not military size is still a strategic edge. You can skip our detailed defense analysis and go directly to 5 Biggest Militaries in the World. 

Military size has played a critical role throughout human history. However, as technology evolved, starting from the early modern period, it changed the landscape of warfare forever. The British were able to colonize much of the world with ease, despite being few in numbers relative to their subjects, because of advanced military technology. 

The Defense Industry: An Analysis

In the present day, technological advantage has replaced the size advantage to a fairly large degree in most military doctrines. These doctrines are executed through investments in military R&D. The global military spending grew by 0.7% in 2021, surpassing the $2 trillion figure. 

The US alone accounted for 38% of this global spending, with a 2021 military budget of a little over $800 billion. Most of these funds go into defense contract obligations. According to a report released by the US Department of Defense, 71% from the 'contract-obligations-and-payroll-spending' budget went to defense contractors. 

The report showed that Lockheed Martin Corporation (NYSE:LMT), The Boeing Company (NYSE:BA) and Raytheon Technologies Corporation (NYSE:RTX) were the government’s top three defense contractors in 2021, respectively. This goes to show that technology matters much more than military size.

There’s many technologies being developed but the ones that have the most to offer in terms of strategic advantages as of late are hypersonic scramjet missiles and glide vehicles, 5G, autonomous systems and AI. The US is already strategically matched by Russia and China in stealth, autonomous systems and air-defense technologies. However, Russia and China have a lead over it in hypersonics. 

In fact, the top DoD contracts are an effort to develop hypersonic technology. According to a DoD report, hypersonics R&D cost the highest amount of money, at $3.2 billion, in US defense contracts for military technology in 2021. It was followed by autonomous systems & AI, at $2.5 billion and 5G at $1.5 billion. 

Most of the contracts for these novel technologies have been awarded to Lockheed Martin Corporation (NYSE:LMT), Raytheon Technologies Corporation (NYSE:RTX), The Boeing Company (NYSE:BA) and Northrop Grumman Corporation (NYSE:NOC).

Insofar as autonomous weapon systems are concerned, even some mid-tier military powers have made significant strides. Turkish Baykar-Bayraktar-TB2 drones supplied to Ukrainian forces have been highly effective in their counter-offensives against Russia. On the other hand, Iranian Shahed-136 drones, which Iran has admitted to exporting to Russia, have been wreaking havoc in Ukrainian cities.
