Introduction: Why Defense Again
One of the most persistently discussed themes in mid-2020s capital markets has been the defense industry. For a long time, defense stocks were viewed as a dull sector with low growth that depended entirely on government budgets. As geopolitical tensions escalated, however, the mood shifted dramatically. Numerous outlets and research institutions have reported that global defense spending has been rising for several years, with the European rearmament trend especially prominent.
This article examines the defense investment theme from multiple angles as of 2026. We cover global defense spending trends, the structure of the defense value chain, major global companies and K-defense export momentum, new frontiers such as drones and space, and the ESG and ethical-investing perspective. The goal is to present both the bull and bear cases so you can form a balanced view.

1. Global Defense Spending: What Changed
1-1. The NATO 2 Percent Target and Beyond
For years, the NATO member guideline for defense spending was 2 percent of GDP. As the security environment changed, however, there has been active discussion, reported by many outlets, about whether that target itself should be raised. Some members and leaders are said to argue that 2 percent is not enough and that a higher level is needed.
The key point is the direction more than the specific figure. In the past, many members failed to reach even 2 percent, but recent reports indicate that a growing number of countries are meeting or exceeding the target. This is sometimes interpreted as a signal that the order environment for defense companies could improve structurally.

1-2. The European Rearmament Trend
Europe maintained relatively low defense spending for a long period. As security threats came into focus, however, several countries including Germany and Poland have been shifting policy toward sharply increasing defense budgets, according to reports. Germany was reported to have created a large special defense fund, and Poland is said to have announced plans to allocate a very high share of GDP to defense.
Analysts note that this trend could create opportunities not only for defense companies within Europe but also for overseas suppliers. At the same time, observers point out that many European countries emphasize domestic production and protecting their own industries, which introduces variables for exporting nations.
1-3. The US Defense Budget
The United States is the world's largest defense spender. The US defense budget is finalized each year through congressional review, and its size is known to be overwhelmingly larger than that of any other country. Institutions such as the Stockholm International Peace Research Institute (SIPRI) have reported that global military spending is on a rising trend and that the United States is by far the largest spender.
US defense companies generate revenue not only from the domestic budget but also through foreign arms exports (Foreign Military Sales, or FMS). It is therefore important to understand that the direction of the US defense budget and the weapons demand of allied nations both feed into earnings.
1-4. Defense Spending Overview Table
The table below conceptually summarizes the relative scale of defense spending by major country. Exact figures vary by year and source, so please verify the latest precise data from authoritative sources such as SIPRI.
| Category | Relative scale | Characteristic |
| --- | --- | --- |
| United States | Very large | World's largest, plus allied exports |
| China | Large | Reported as rapidly rising |
| Europe combined | Rising | Rearmament trend prominent |
| South Korea | Upper-middle | Reported emergence as export power |
| Japan | Expansion debated | Reported intent to expand defense budget |
2. Understanding the Defense Value Chain
Treating the defense industry as a single block makes investment judgment difficult. In reality it consists of several value-chain stages, each with different business characteristics and revenue structures.

|
v
[End user: armed forces]
2-1. Platform OEMs
Platform OEMs are companies that integrate and produce large weapons systems such as fighter jets, warships, tanks, and submarines. Contracts are large, development cycles are long, and once adopted, systems remain in service for decades. Barriers to entry are very high, but the risk of development delays and cost overruns also exists.
2-2. Missiles and Ammunition
Missiles and ammunition are highly consumable. When inventories are depleted through conflict or training, replenishment demand arises. Demand for precision-guided weapons and air-defense missiles in particular has been reported to be rising. Ammunition may look relatively simple, but expanding production capacity takes time, so supply bottlenecks can emerge, observers note.
2-3. Electronic Warfare and Sensors
The share of electronic warfare, radar, sensors, and communications equipment in modern warfare is growing. This area is technology-intensive with a high software component, which some assess as potentially supportive of margins. It is also closely tied to the semiconductor and electronic-component supply chains.
2-4. MRO and Upgrades
MRO refers to maintenance, repair, and operations. Because weapons systems remain in service for decades after acquisition, maintenance and upgrade demand arises steadily. This business offers low volatility and recurring revenue, so investors often watch it for its stability.
| Value-chain stage | Revenue characteristic | Volatility |
| --- | --- | --- |
| Platform OEM | Large long-term contracts | Medium (dev risk) |
| Missiles / ammo | Consumable replenishment | Conflict-dependent |
| EW / sensors | Tech-intensive, good margins | Medium |
| MRO / upgrades | Recurring revenue | Low |

| BAE Systems | UK | Diversified defense |
| Rheinmetall | Germany | Ammunition, vehicles |
| Leonardo | Italy | Helicopters, avionics |
| Thales | France | Electronics, cyber, space |
4. K-Defense Export Momentum
In recent years, reports have repeatedly noted that South Korea's defense exports have grown significantly. Reasonable pricing, fast delivery, and stable quality are cited as strengths.
4-1. Major Companies
- Hanwha Aerospace: Reported to be expanding into self-propelled artillery, armored vehicles, aircraft engines, and space. Export expansion to Europe and elsewhere is frequently mentioned.
- Korea Aerospace Industries (KAI): Known for producing the FA-50 light combat aircraft, trainers, and helicopters.
- Hyundai Rotem: Handles tanks and vehicles, with exports to Poland among the reported deals.
- LIG Nex1: Reported to have strengths in missiles, precision-guided weapons, and surveillance and reconnaissance.
4-2. The Poland Export Case
There have been repeated reports that Poland decided to acquire large quantities of Korean tanks, self-propelled artillery, and light combat aircraft. This is cited as a symbolic case of K-defense entering the European market in earnest. That said, details such as follow-on contracts, local production, and financing terms can change, so it is worth continually tracking how the reporting develops.

| Variable | Local production demands, tech-transfer burden |
| Variable | Exchange rates and financing terms, policy shifts |
| Variable | Uncertainty in follow-on volume contracts |
5. New Frontiers: Drones, Space, Cyber
Beyond traditional platforms, new security domains are assessed to be growing rapidly.
5-1. Drones and Unmanned Systems
Low-cost drones and unmanned systems have come into focus for their important role in modern conflict. They are used for everything from reconnaissance to strike, and demand for counter-drone (anti-drone) defense is reported to be rising alongside. This field has attracted not only large traditional defense firms but also many newcomers, making competition fierce.
5-2. Space and Satellites
Satellite communications, reconnaissance satellites, and satellite navigation are core military infrastructure. As commercial space companies advance and connect with the military space domain, investment interest in launch vehicles and satellites is reported to be rising.
5-3. Cybersecurity
Beyond physical weapons, defensive and offensive capabilities in cyberspace have become central to security. Cybersecurity connects to the IT segments of defense companies and to specialized security firms; it is assessed as high-growth, while also being hard to classify as pure defense.
| New frontier | Characteristic | Investment view |
| --- | --- | --- |
| Drones / unmanned | Low-cost, high-volume, fierce | Selectivity matters |
| Space / satellites | Infrastructure, dual-use | Long-term theme |
| Cybersecurity | Software-centric | Distinct from pure defense |
6. Investment Approaches: Single Stocks vs Defense ETFs
There are broadly two ways to invest in the defense theme: individual stocks and ETFs.
6-1. Individual Stocks
Individual stocks let you bet concentratedly on a specific company's growth. However, a single company is heavily exposed to idiosyncratic risks such as lost contracts, development delays, cost overruns, and the policy shifts of a particular country. Sufficient company analysis and diversification should be a prerequisite.
6-2. Defense ETFs
ETFs provide the effect of diversifying across many defense companies. They are relatively insulated from a single company's bad news, but they incur management fees and decline together when the whole theme corrects. Each ETF differs in its holdings, weightings, and regional composition, so checking the composition before investing is important.
Single stock vs ETF trade-off

| Category | Individual stocks | Defense ETFs |
| --- | --- | --- |
| Diversification | Low | High |
| Idiosyncratic risk | Large | Mitigated |
| Cost | Trading costs | Management fees |
| Difficulty | High | Relatively lower |
7. The Bull Case and the Bear Case
For balanced judgment, we examine both sides.
7-1. The Bull Case
- There is a view that geopolitical tensions are unlikely to be resolved quickly.
- European rearmament and discussion of raising the NATO target lead some to expect structurally rising demand.
- The long life cycle of weapons systems is seen as making long-tail revenue such as MRO stable.
- Reports continue that new suppliers, such as K-defense, are expanding the market.
7-2. The Bear Case
- Defense depends heavily on government budgets and policy, so it can be hit when policy changes.
- Some note that expectations could cool quickly if peace negotiations or de-escalation proceed.
- There is a view that expectations are already substantially priced in, creating valuation risk.
- Execution risks such as development delays, cost overruns, and supply-chain bottlenecks persist.
- On the ESG side, the trend of excluding defense from investment universes could be a variable.
| Perspective | Core argument |
| --- | --- |
| Bull | Structural demand, long-term contracts, new supplier expansion |
| Bear | Policy dependence, peace risk, valuation, ESG variable |
8. Cycle and Policy-Dependency Risk
Defense is fundamentally an industry dependent on government spending. It is therefore important to understand the following risks.
- Budget cycles: Defense budgets are the product of political negotiation and can shift during changes of government or fiscal tightening.
- Contract timing: Large contracts have a long lag between signing and actual revenue recognition. An order announcement may not translate immediately into earnings.
- Geopolitical reversal: If de-escalation or diplomatic solutions advance, demand expectations can correct quickly.
- Exchange rates: For companies with a large export share, earnings can swing with currency moves.
- Supply chain: Bottlenecks in parts and materials can cause delivery delays and cost increases.
These variables do not all push in one direction. The same event can act as an opportunity for one company and a threat for another.
9. ESG and the Ethics Debate in Defense Investing
An indispensable topic in defense investing is ethical consideration. Investing in the weapons industry is inherently an area where value judgments come into play.
9-1. The Exclusion Argument
Some investors and institutions have classified the weapons industry as a sin stock and excluded it from their investment universe. Their position is that allocating capital to an industry directly tied to loss of life is ethically inappropriate.
9-2. The Reassessment Argument
Conversely, from the view that security is the foundation of peace and deterrence, there have been reported discussions that the defense industry should be reinterpreted under the social (S) dimension of ESG. In Europe especially, as security threats came into focus, there is said to be a movement to reassess whether blanket exclusion of defense is justified.
9-3. The Investor's Choice
Ultimately this is not an area with a fixed correct answer; it is a matter of choice that depends on individual values and beliefs. It is advisable to clarify your own investment principles and ethical standards before making decisions.
| Position | Core claim |
| --- | --- |
| Exclusion | Weapons are sin stocks, investment inappropriate |
| Reassessment | Security is a social value, ESG reinterpretation needed |
| Middle ground | A matter of choice based on personal values |
10. A Practical Checklist
Below is a set of items worth reviewing when evaluating the defense theme. This is merely a starting point for decision-making and is not, in itself, an investment recommendation.
- Have you identified which value-chain stage the company belongs to?
- What is the split between the domestic budget and exports in its revenue?
- Have you checked the backlog and the flow of actual revenue recognition?
- Is there a history of development delays or cost overruns?
- How does the valuation compare to its own history and to peers?
- How would it be affected if policy and geopolitical scenarios change?
- Does it align with your own ethical standards?
- Between single stocks and ETFs, which approach suits you?
11. Frequently Asked Questions (FAQ)
Q1. Is it too late to get into defense stocks now?
Timing is hard to assert. Some believe expectations are already priced in, while others believe structural demand growth continues. Neither can be stated as fact, so you should judge based on your own analysis and risk tolerance.
Q2. Which is better, single stocks or ETFs?
There is no single right answer. If you are confident in company analysis and want concentration, single stocks may fit; if you want diversification and convenience, an ETF may fit. Many investors blend the two.
Q3. Will K-defense exports keep rising?
Reports of export expansion continue, but there are many variables such as follow-on contracts, local-production demands, exchange rates, and policy shifts. Rather than assuming every reported plan materializes exactly, it is safer to keep tracking how things progress.
Q4. Is defense investing ethically problematic?
This is a matter of value judgment. Some investors exclude the weapons industry; others view security as a social value. Clarifying your own standard comes first.
Q5. What happens to defense stocks if peace talks advance?
Some hold that demand expectations cool and share prices may correct in the short term. At the same time, there is also a view that long-term contracts and MRO revenue tend to remain relatively steady.
12. Regional Security Landscape Check
Defense demand looks different by region. Tension in one region may move independently of another, and sometimes it ripples across regions.
12-1. Europe
Europe is frequently cited as the center of the recent security investment theme. Reports continue of Eastern European countries raising defense budgets, and major Western European nations such as Germany and France are also said to be strengthening defense capabilities. Discussions of intra-regional defense cooperation and joint procurement are reported as well.
12-2. Asia Pacific
In the Asia Pacific region, Japan's intent to expand its defense budget, Australia's submarine acquisition discussions, and South Korea's export expansion are frequently mentioned. Analysts note that regional maritime security and missile defense are emerging as central topics.
12-3. Middle East
The Middle East is traditionally known as a region with large arms imports. Weapons-acquisition demand tends to fluctuate with shifts in the situation, and competition is reported among the United States, Europe, and newly entering supplier nations.
Regional demand drivers (concept)
Europe -> rearmament, eastern budgets up
Asia Pacific -> maritime security, missile defense
Middle East -> situational shifts, import reliance
North America-> domestic budget, allied export hub
| Region | Main driver | Characteristic |
| --- | --- | --- |
| Europe | Rearmament | Emphasis on local production |
| Asia Pacific | Maritime security | Active imports and exports |
| Middle East | Situational shifts | Large import reliance |
| North America | Domestic budget | World's largest market |
13. Defense Companies Through Financial Metrics
There are metrics often referenced when evaluating defense companies. The below is a general overview and does not present any specific company's figures.
- Backlog: Often used as an indicator of forward revenue visibility.
- Operating cash flow: Given the long-contract nature, the stability of cash flow is evaluated as important.
- Debt level: Because the industry sees frequent large investments and acquisitions, checking financial health is needed.
- Dividend policy: Some large defense companies are assessed as known for stable dividends.
| Metric | Meaning | Caveat |
| --- | --- | --- |
| Backlog | Future revenue visibility | Recognition timing lag |
| Cash flow | Business stability | Affected by contract cycles |
| Debt | Financial health | Acquisition activity variable |
| Dividend | Shareholder return | Policy can change |
14. Correcting Common Misconceptions
There are a few common misconceptions in defense investing.
- Misconception 1: When war breaks out, defense stocks always rise. In reality, expectations may already be priced in, or the lag between contract and revenue recognition may delay any reflection.
- Misconception 2: Defense is unrelated to the economy. Because it is influenced by government fiscal conditions and policy, it is hard to view it as entirely unrelated.
- Misconception 3: The bigger the company, the safer. Being large does not exempt a firm from development-delay or cost-overrun risk.
| Misconception | Reality |
| --- | --- |
| War = price surge | Pre-priced expectations, lag exists |
| Economy-independent | Influenced by fiscal and policy |
| Big = safe | Execution risk persists |
15. Conclusion
Defense is a theme where geopolitics, policy, and technological change are intricately intertwined. Structural shifts such as rising global defense budgets, European rearmament, and the rise of K-defense are clear opportunity factors. Yet there is also the weight of policy dependence, peace risk, valuation pressure, and ethical consideration. Weighing the bull and bear cases together, and approaching carefully in light of your own investment principles and values, is what is required.
