IN Brief:
- Auriga Space and DEVCOM Armaments Center will assess electromagnetic counter-UAS launch technology.
- The containerised Hermes prototype accelerates an interceptor using stored electrical energy.
- Power supply, thermal control, launcher life, guidance, sensing, and total engagement cost remain unresolved.
Auriga Space and the US Army Combat Capabilities Development Command Armaments Center have signed a three-year research agreement to evaluate electromagnetic launch technology for counter-drone interception.
The cooperative research and development agreement gives Auriga access to Army expertise in munitions, testing, and weapon integration, while DEVCOM can examine whether electrical acceleration offers a lower-cost way to fire interceptors against small uncrewed aircraft.
Auriga’s Hermes prototype packages the launch system inside a 10ft container. Instead of using a rocket motor or conventional gun propellant, the system stores electrical energy and releases it rapidly to accelerate a projectile towards the target.
That architecture could reduce dependence on energetic launch materials and allow velocity to be adjusted for different projectiles or engagement conditions. The current agreement remains a research mechanism rather than a procurement contract, however, and no operational requirement or production order has been established.
Electromagnetic launch has been studied for artillery, naval weapons, space access, and laboratory testing for decades. The persistent engineering problem is not achieving one successful shot, but packaging the required power, cooling, controls, and mechanical durability into a field system that can fire repeatedly.
Power storage is the first constraint. A launcher must release substantial energy in a short period, requiring capacitors, switching equipment, conversion systems, protection circuits, and thermal management. Those components add weight, cost, and maintenance even when the projectile itself remains inexpensive.
Counter-UAS operations also require rapid re-engagement. The system must recharge quickly enough to handle several targets without overheating or demanding a generator and support vehicle so large that mobility and deployment become impractical.
Launcher wear may ultimately govern the operating economics. High currents, mechanical forces, and heat can damage rails, coils, insulation, and switching components, turning a nominally low-cost shot into an expensive maintenance event if critical parts require frequent replacement.
The interceptor creates a separate design problem because high acceleration can damage conventional electronics, seekers, batteries, and control surfaces. Components must be ruggedised while remaining light enough to reach the required velocity and retain useful manoeuvrability.
A purely ballistic projectile would depend on highly accurate target prediction, particularly against small drones changing speed or direction. Guidance can improve probability of kill, but seekers, actuators, communications, and power supplies add cost and complexity.
Hermes will therefore need to connect with radar, electro-optical sensors, or another tracking system capable of producing a sufficiently precise firing solution. The launcher alone does not detect, classify, identify, or authorise engagement of the target.
Containerisation helps with transport and protects equipment from the environment, while a standard enclosure may simplify installation around bases, depots, or infrastructure. The deployed footprint will still include generators, cooling, sensors, communications, maintenance access, and safety zones.
Military qualification will place further demands on the system. High-voltage equipment must remain safe after transport, shock, vibration, rain, dust, electromagnetic interference, and long periods in storage, while crews need procedures for isolating stored energy during maintenance or damage.
The US Army is pursuing a layered response to low-cost drones. Electronic warfare can disrupt control links, guns offer relatively economical fire, missiles extend engagement range, and directed-energy systems promise low theoretical cost per shot.
Britain’s work on Skyhammer and DragonFire illustrates the same industrial search for affordable interception layers. Auriga approaches the cost problem by replacing conventional launch propulsion rather than the interceptor’s guidance or terminal effect.
Manufacturing could draw on suppliers beyond the established missile base, including companies producing power electronics, capacitors, advanced conductors, thermal equipment, precision structures, and rugged computing. Qualification for military use will narrow that pool, but it may still offer more capacity than specialised rocket-motor production.
Outdoor flight tests should reveal projectile stability, actual energy consumption, launcher consistency, and whether the concept can move from controlled firing towards representative engagements. Probability of kill must then be measured alongside full cost per shot, including power generation, barrel or coil replacement, sensors, maintenance, and crew.
Production planning should begin before a successful demonstration creates sudden demand. Specialist electrical components can carry long lead times, while a start-up may find it harder to expand quality, safety, and field-support teams than to build additional prototype hardware.
The research agreement gives Auriga time to establish where electromagnetic launch genuinely reduces cost and where expense has merely shifted from the interceptor into the launcher. Hermes will become a credible counter-UAS product only when repeated shots, field reliability, and maintainable power hardware are demonstrated together.
