ASX Defence Stocks Are Surging on Geopolitical Fear, But What Are Investors Actually Buying?

DroneShield (ASX: DRO) is up approximately 330% over the past twelve months. The broader ASX 200 managed around 6% over the same period. That gap alone tells you something significant is happening in the defence sector right now. Renewed tensions in the Middle East and the ongoing war in Ukraine have pushed defence stocks back into focus in 2026, and Australian investors are taking notice. The theme is real and well-supported. The question worth asking before acting on it is what investors are actually buying into at today's prices.

The World Is Rearming, and Drones Are at the Centre

Wars in Ukraine and the Middle East have changed how governments think about defence. They have also changed what they are spending money on.

Cheap, hard-to-detect drones have proven devastatingly effective on the battlefield. That realisation has triggered a global race to build better counter-drone systems, the technology that detects and neutralises drone threats before they cause damage.

According to research firm MarketsandMarkets, the global counter-drone market is currently worth around US$6.6 billion and is projected to nearly triple to US$20.3 billion by 2030. That kind of growth does not happen in a niche. It happens when governments treat something as a national security priority.

And that is exactly what is playing out. Global military spending hit a record US$2.7 trillion in 2024, according to SIPRI, the tenth consecutive year of increases. Europe is spending more. The Middle East is spending more. The Indo-Pacific is spending more.

Where Australia Fits In

Australia is not sitting on the sidelines. Defence spending currently sits at approximately A$59 billion for 2025-26, around 2% of GDP, with projections to grow at roughly 5.9% annually through to 2030. That trajectory is likely to steepen given US pressure on allies and Australia's own strategic reassessment of the Indo-Pacific.

The AUKUS agreement is estimated to cost Australia approximately A$368 billion over 30 years, with A$2.7 billion already committed in this year's budget. Notably, the government also accelerated billions in planned defence spending forward into 2025-26 ahead of schedule, signalling urgency rather than just long-term planning. That multi-decade pipeline of spending is what makes Australian defence technology interesting from an investment standpoint.

For ASX investors, the key listed names include DroneShield (ASX: DRO) in counter-drone systems, Austal (ASX: ASB) in naval shipbuilding, and Codan (ASX: CDA) in military communications.

DroneShield: The Case Study Worth Understanding

DroneShield is the standout name in this space. Its FY2025 revenue came in at A$216.5 million, up 276% from the prior year, and the business turned profitable for the first time. Management has flagged A$104 million in already-secured revenue for FY2026, which gives the company unusual forward visibility for a business of its size.

The growth story is real. So are the risks.

The stock is expensive relative to peers, trading at roughly 15 times sales compared to the sector average of 5.6 times. Revenue still depends heavily on large contract wins, which can be lumpy and unpredictable. And with a weekly volatility measure above 14%, sharp price swings in both directions are part of the package. As recently as March 20, the stock dropped 9.5% in a single session after investors grew concerned about how quickly the company can scale production to meet its A$2.4 billion capacity target by the end of 2026.

This is not a slow and steady compounder. It is a high-growth, high-risk play on a genuine global trend.

What Investors Should Think About

The long-term case for defence technology is credible. Governments around the world have been building defence spending into their budgets for years, not months. Australia's role in AUKUS and its strategic position in the Indo-Pacific reinforce that locally.

The harder question is timing and price. DroneShield has already run hard. Buying after an approximately 330% twelve-month rally, at a premium valuation, leaves less room for error if contract timing slips or sentiment shifts.

The theme is sound. Patience and position sizing matter just as much as the idea itself.

Key Takeaways:

• Global defence spending is at record levels and still rising, with drones and counter-drone technology at the centre of the shift
• Australia's defence budget is growing steadily, supported by AUKUS commitments and Indo-Pacific tensions
• DroneShield has delivered real revenue growth, but carries a premium valuation and high share price volatility
• The structural case for ASX defence stocks is strong; the entry point and risk tolerance are what investors need to get right
