Another US contract has put DroneShield Ltd (ASX: DRO) back on investors' radar on Tuesday.
At the time of writing, the DroneShield share price is up 3.55% to $3.21.
The ASX defence stock was stronger earlier in the session, hitting an intraday high of $3.33 in morning trade.
Even with today's gain, DroneShield shares are still down around 11% over the past month.
Zoom out, though, and the longer-term picture looks very different. The stock remains up about 150% over the past year.
Let's take a closer look at today's announcement.

A new US defence contract
According to the release, DroneShield has secured a $24.9 million contract linked to the US Department of War's Joint Interagency Task Force 401.
The contract has an initial value of $19.3 million, with another $5.6 million in options over a 5-year period.
It covers the supply of mobile and fixed-site counter-drone systems, including hardware, subscriptions, warranties, and services.
DroneShield said the hardware is available from existing planned production, with deliveries expected across 2026 and 2027.
The company also said the contract requires it to buy and install third-party interoperable solutions alongside its own products.
Payments for the initial contract value are expected from the second half of 2026 through the first half of 2027.
At least $10 million of the initial contract value is expected to be recognised as committed revenue in FY 2026.
The remaining amount is expected to be recognised in FY 2027.
Why investors are buying
The US defence link appears to be the main reason investors are buying the stock today.
DroneShield said JIATF-401 is the US Department of War's main organisation for coordinating counter-drone efforts across the joint force.
Its role is to help partners acquire counter-drone capability in response to the growing threat from drones.
Chief Executive Angus Bean said the contract shows rising demand for counter-drone capability across complex operating environments.
He said customers are looking for solutions that combine fast deployment with ongoing operational support.
The company's US President, Ray Fitzgerald, also said the contract represents another milestone in DroneShield's growth in the United States.
Foolish Takeaway
The contract is a useful win for DroneShield, especially given the US defence customer and multi-year structure.
It also gives investors more detail on future revenue, with at least $10 million expected to land in FY 2026.
Still, expectations around DroneShield are already high.
Even after the recent monthly pullback, the company has a market capitalisation of about $3 billion.
The next test is whether DroneShield can keep turning strong demand into larger contracts and revenue growth.
