BAE Systems unveils a Technology Readiness Level 6 high-power microwave weapon to counter drone swarms
BAE Systems unveiled a high-power microwave weapon at AUSA 2026 that it says has reached Technology Readiness Level 6. Only the microwave half of the pairing works without conventional ammunition, and no Army adoption is shown.
The Product Desk

Key figures: more than 99 percent of the HPM system's components are commercial off-the-shelf; the HPM system supports four deployment configurations; BAE says Scorpio-XR doubles the range of existing precision-guided projectiles fired from 155 mm cannons.
| Figure | Value | Note | Claim |
|---|---|---|---|
| HPM components commercial off-the-shelf, more than | 99% | 4 | |
| HPM deployment configurations | 4 configurations | 5 | |
| Cannon size for existing guided projectiles | 155 mm | BAE says Scorpio-XR doubles their range | 8 |
What happened
- The microwave weapon engages groups of drones with electromagnetic energy and can keep taking successive targets for as long as its power supply remains available.
- BAE says outdoor range testing, including tests involving billions of microwave pulses to document effects on targets, has validated the weapon's operation.
- The weapon is modular and comes in four configurations: fixed installations, towed systems, combat vehicle integration and maritime platforms.
- The air-transportable MDACS artillery platform can launch the guided Hypervelocity Projectile against aerial threats.
- MDACS can also fire Scorpio-XR at fixed and moving ground targets, and BAE says that round doubles the range of existing precision-guided projectiles from 155 mm cannons.
Why it matters
- constraint The saving on missile interceptors applies to the microwave layer. MDACS is a projectile-based layer, so a buyer still has to plan munition supply for that half.
- contradiction The pitch is swarm defense, but the reported testing documents effects on targets. The source does not say how many drones were engaged at once.
- constraint The source says the eventual role of either system depends on further development, testing and procurement decisions.
BAE Systems is selling against the ammunition limit of a crew defending a fixed site from a drone swarm. Missile interceptors carry finite ammunition supplies, and replacing each shot can create substantial logistical demands in a prolonged engagement [3]. The buyer in view is the US Army [1].
The pitch is a layered defense in which the two systems complement each other [9]. In the source's description, one system uses directed energy to engage drones without conventional ammunition, and the other relies on high-velocity projectiles for kinetic interception [12]. In our view, the claim about sparing missile interceptors belongs to the microwave weapon alone. The artillery layer swaps in a different kind of round.
The microwave weapon needs no ammunition, but it depends on its power supply. BAE says its architecture is more than 99 percent commercial off-the-shelf components and that this supports manufacturing and sustainment [4]. Each of its four configurations can accommodate different power requirements [13].
The testing described is real but specific. BAE reports outdoor range validation at Technology Readiness Level 6 [6]. The reported announcement does not include a price, a power draw or an engagement range. Jason Casciotti, vice president of BAE Systems' Weapon Systems product line, said BAE's aim is to get mature technology into operational use more quickly, and he pointed to validated designs and a resilient supply chain [10]. The source adds that the eventual role of either system depends on further development, testing and procurement decisions [11].
For anyone specifying a counter-drone layer, it helps to sort each layer in a two-column table. In the first column, write what the layer spends on each engagement: a missile, a projectile or electrical power. In the second, write who measured the claim, the vendor or the customer. On BAE's account, the microwave weapon spends power and its testing claims are BAE's [6]. MDACS spends projectiles [12].
We'd judge each layer on that table before judging the pair. The tradeoff is that the microwave weapon's advantage, no ammunition resupply, lasts only while its power supply does [2].
What to watch
- Any Army test, program or procurement announcement that names BAE's HPM or MDACS, since the source ties their role to those decisions.
- Published power draw, engagement range and swarm-size results from the outdoor range testing, ideally from the customer rather than BAE.
- Cost and supply figures for Hypervelocity Projectile rounds, which would show how much of the interceptor saving the artillery layer keeps.
