At the end of the week, a meeting took place in Washington that could have an impact not only on geopolitics but also on stock markets. US President Donald Trump convened the heads of the biggest arms companies and, after the meeting, announced an ambitious plan: to significantly increase production of some of the most advanced weapons.
In his words, manufacturers have committed to speed up production of selected systems to four times the current rate. The push comes at a time when U.S. military operations and rising tensions in the Middle East are increasing the consumption of expensive missiles and interceptors. This is not isolated news for investors watching the defense sector. It hints at a broader trend: rapid rearmament and long-term growth in military spending that could fundamentally change the dynamics of the entire industry.
The White House meeting and the plan to quadruple production
Donald Trump announced the plan after meeting with the heads of several of America's largest defence companies. Among the participants were representatives from companies such as $BAESF, $BA, $HON, $LHX, $LMT, $NOC and $RTX.
According to the President, the companies agreed on the need to significantly increase the production of so-called "exquisite class" weapons, i.e. technologically very advanced and at the same time difficult to produce systems. This category includes, for example, Tomahawk missiles , Standard Missile-6 or the most advanced versions of Patriot PAC-3 MSE interceptors.
According to Trump,the increase in production is to take place as quickly as possible. Meanwhile, some production lines have been expanding for several months, so part of the production expansion is already underway. The meeting also reflects the US administration's broader concern that current conflicts are gradually depleting supplies of key munitions. Modern anti-missile systems or precision missiles can cost millions of dollars apiece and often take years to produce.
War and empty warehouses
The impetus for accelerating production is primarily due to the ongoing conflict between the United States, Israel and Iran. Hundreds of missiles and interceptors have been fired in the first days of operations, according to defence analysts, rapidly reducing the US military's stockpile. During the brief conflict in 2025, for example, U.S. and Israeli forces used more than 150 THAAD interceptors, about a quarter of the global stockpile of such missiles.
The problem is that production of such weapons is not easily scalable. Production of Patriot interceptors today is around 600 to 650 units per year, and it may take several years to increase significantly. The Pentagon has therefore been entering into framework agreements with manufacturers in recent months to speed up production of key systems, including Patriot, THAAD and Tomahawk missiles.
Defence sector back in investors' sights
For stock markets, this development has a clear logic. Weapons companies are among the main beneficiaries of rising military budgets. Analysts point out that increased demand for missiles and anti-missile systems can significantly boost the revenues of companies such as Lockheed Martin, Northrop Grumman or L3Harris Technologies.
The defence sector has already responded with growth this year. For example, the iShares U.S. Aerospace & Defense ETF has gained roughly 10% in 2026, while the broader S&P 500 index has been flat. Moreover, some analysts point out that this is not just a short-term reaction to the current conflict. Rising military spending is a global trend, and the United States is considering further budget increases, while Europe and Asia are also ramping up defense investments.
Political pressure on arms companies
At the same time, Trump has put strong pressure on defence firms to invest more in production in recent months. Earlier this year, he signed an executive order to limit dividends and share buybacks at arms companies if they fail to accelerate delivery of military equipment.
In doing so,the administration wants to force companies to channel more capital into new factories, production lines and research. The move is relatively unusual in U.S. defense policy because the government has traditionally left the capital structure of contractors to their discretion. For investors, this means that the sector can be both an opportunity and a source of regulatory risk.
A new era of arms manufacturing
Events in recent weeks show that the global security environment is changing rapidly. Modern conflicts consume vast quantities of precision missiles and anti-missile systems, which are technologically and logistically challenging to produce. This creates a paradox: the most advanced weapons, which are supposed to provide technological superiority, are also becoming one of the greatest constraints on military strategy.
This is why governments are today pushing manufacturers to massively expand their capabilities. If these plans actually come to fruition, the defence industry may within a few years resemble more like Cold War-era mass production than today's relatively limited production of high-end systems. For investors, then, something else may be more important than the conflicts themselves: whether arms companies can turn political pressure and record budgets into long-term production growth and thus a more stable order flow for many years to come
