L3Harris secures up to $106 million to supply a counter-drone system born from Ukraine's battlefields, as the Army scrambles to build layered defenses against increasingly common aerial threats.
The US Army has placed a bet on a system forged in the crucible of a real war. L3Harris announced a contract worth up to $106 million to supply its Vampire counter-drone platform, a vehicle-mounted weapon designed to shoot down hostile drones and remotely piloted aircraft with laser-guided rockets.
The contract addresses what the Army calls an urgent requirement. Drone threats to ground forces have escalated dramatically in recent years, and the existing suite of counter-UAS tools hasn't kept pace. Vampire slots into what the Army describes as a "layered defense" approach, the idea that no single weapon can handle every aerial threat, so multiple systems at different ranges and price points must work together.
How Vampire Works
At its core, Vampire is a self-contained firing platform. It mounts on a truck bed or similar vehicle and combines a telescopic mast with an electro-optical and infrared targeting system. A launcher sits ready to fire effectors, which in military parlance means projectiles designed to destroy something.
The primary weapon is the Advanced Precision Kill Weapon System, or APKWS. These are essentially Hydra 70 rockets, a 2.75-inch projectile that has been in US inventory since the Vietnam era, fitted with a laser-homing nose kit. The result is a guided weapon that costs a fraction of purpose-built anti-drone missiles. The economics matter enormously here. Using a $3 million missile to shoot down a $500 commercial drone is not a sustainable strategy, and the Pentagon knows it.
The system can engage targets out to six kilometers, roughly 3.8 miles. Its laser designator can highlight targets while coordinating with other platforms, enabling what L3Harris calls a distributed approach to engagement. Multiple Vampires could theoretically share targeting data, creating overlapping fields of fire without centralized coordination.
L3Harris emphasizes that Vampire has a modular plug-and-play architecture. Sensors, effectors, and radio management systems can be swapped or upgraded without redesigning the entire platform. This modularity reflects a broader trend in defense procurement, where the ability to upgrade individual components is valued over monolithic systems that become obsolete as a whole.
Born in Ukraine, Tested in Combat
The timing is notable. L3Harris says Vampire was developed at the beginning of Russia's full-scale invasion of Ukraine, specifically to counter the drone threats that have defined modern ground warfare. The system has since accumulated more than 350,000 operational hours in support of European combat operations since 2023.
Ukraine has been the proving ground for a generation of counter-drone technology. Both sides in the conflict have deployed commercial and military drones in unprecedented numbers, forcing rapid innovation on both the offensive and defensive sides. Systems that were theoretical concepts in 2021 have been stress-tested in actual combat, and the ones that survived are now being adopted by militaries worldwide.
The APKWS rocket itself has found applications beyond Vampire. British Typhoon fighter jets deployed to the Middle East have been fitted with the same laser-guided rockets as a relatively inexpensive drone-busting option. The Royal Navy has equipped Wildcat helicopters with Martlet missiles for anti-drone work. The pattern across NATO militaries is consistent: find the cheapest guided weapon that can reliably kill small drones, then scale it up.
The Gap in Layered Defenses
The Army's layered defense concept typically includes short-range systems like directed energy weapons and electronic jamming, medium-range options like Vampire, and longer-range interceptors for larger or faster threats. Each layer addresses different attack profiles, from swarms of cheap commercial drones to larger military-grade unmanned aircraft.
Vampire fills a specific gap: a mobile, relatively affordable kinetic kill option that doesn't rely on line-of-sight jamming or directed energy. Electronic warfare can be effective against drones that rely on radio links, but autonomous drones that follow pre-programmed waypoints are immune to jamming. Directed energy weapons, while promising, remain limited by power requirements and atmospheric conditions. A guided rocket works regardless of whether the target is listening to radio signals or flying in fog.
L3Harris has ramped up production at a new facility in Huntsville, Alabama, in anticipation of demand from the US and allied nations. The company has not disclosed how many systems the Army will receive for its $106 million, but the investment signals that Vampire is expected to be a volume product rather than a niche capability.
Counter-Perspectives and Open Questions
Not everyone views the arms race in counter-drone systems as straightforwardly positive. Some defense analysts argue that the rapid proliferation of drone-killing technology reflects a failure to address the root cause: the unchecked spread of cheap, capable drones to state and non-state actors alike. Building better defenses is necessary, but it is a reactive posture.
There are also questions about cost-effectiveness at scale. While APKWS rockets are inexpensive relative to dedicated anti-air missiles, they are not cheap in absolute terms. Each rocket costs several thousand dollars, and a typical engagement might require multiple rounds to guarantee a kill. Against swarms of dozens or hundreds of drones, even "low-cost" interceptors add up quickly.
Directed energy weapons, which can fire for the cost of electricity, remain the theoretical endgame for counter-drone defense. Several programs are in development, but none have reached the fielding stage at the scale needed to replace kinetic interceptors. Vampire represents the practical present, while lasers represent the aspirational future.
The modular design could also prove to be a double-edged sword. Open architectures are easier to upgrade but also more complex to maintain and integrate. Field reports from Ukraine have occasionally highlighted the challenges of keeping sophisticated electronic systems operational in harsh combat conditions.
For now, the US Army is betting that a system proven in Ukraine's skies can protect American forces and infrastructure from an evolving drone threat. The $106 million contract is a down payment on a problem that is unlikely to get smaller anytime soon.
