ASX defence shares are charging higher as escalating conflict in the Middle East fuels expectations of higher military spending.
Tensions between the United States, Israel, Iran, and Hezbollah intensified over the weekend. Iran reportedly launched waves of Shahed 136 one-way attack drones toward targets across the Gulf region, including the United Arab Emirates.
The escalation has pushed oil prices higher and put defence capability back at the centre of investor focus.
Here are 3 ASX defence stocks leading the charge.

DroneShield Ltd (ASX: DRO)
The DroneShield share price is up 10.50% today to $4 apiece.
That brings its gains to roughly 24% over the past week.
DroneShield specialises in counter-drone detection and mitigation systems. Its technology is designed to identify, track, and disable hostile drones, including systems similar to the Shahed 136 platform reportedly used in recent attacks.
As drone warfare becomes more prominent, demand for anti-drone solutions has accelerated globally. Governments are reassessing defence readiness, particularly around critical infrastructure, airports, and military facilities.
The latest developments in the Middle East have only highlighted how relevant DroneShield's technology has become.
Elsight Ltd (ASX: ELS)
The Elsight share price is up 10.99% today to $5.25.
Even more striking, the stock has surged almost 50% in just 1 week.
Elsight provides secure connectivity solutions for drones and autonomous systems. Its Halo platform enables reliable data transmission across multiple communication networks, which is critical for military, emergency response, and unmanned operations.
As drone deployment expands across conflict zones, secure and uninterrupted connectivity becomes increasingly important. That longer-term shift appears to be driving renewed interest in the company.
However, after such a rapid move, volatility is likely to remain high in the near term.
Electro Optic Systems Holdings Ltd (ASX: EOS)
The EOS share price is currently up 10.58% to $9.93. Earlier in the session, the stock was up more than 15%.
EOS shares are now up close to 40% over the past week.
The company recently announced it had secured a contract with a Middle Eastern country for its remote weapon systems (RWS). These systems are designed to deliver highly accurate defensive fire, including against drone threats.
In a region now experiencing live drone and missile attacks, that capability is clearly front of mind for defence planners. The timing of the contract has strengthened the view that EOS sits in a strategically important segment of the market.
Is it too late to buy?
History shows defence spending usually climbs when global tensions rise. And once governments lift budgets, they rarely reverse those decisions quickly.
Right now, drone warfare and counter-drone defence are at the forefront of modern conflicts.
All 3 stocks have surged in a matter of days. That reflects genuine shifts in global risk, but it also means expectations have moved quickly.
The real test will be execution. Can these companies convert stronger demand into sustained revenue growth and improve margins?
If tensions in the Middle East persist, these defence names could remain in favour. But after such rapid gains, investors should expect volatility and manage position sizes carefully.
