Fire Storm 250 Drone: What the IAI and Sig Sauer M250 Test Showed
Israel Aerospace Industries and Sig Sauer demonstrated a quadcopter carrying an M250 light machine gun over a simulated battlefield, firing in single-shot and semi-automatic modes. On October 13, 2026, Defense News reported that Sig Sauer and Israel Aerospace Industries (IAI) announced a firing test of the Fire Storm 250.
The test paired IAI's reusable, heavy-duty quadcopter with Sig Sauer's M250 light machine gun mounted on a stabilized mount with a 53-pound remote-controlled weapon system. The trial showed an armed quadcopter identifying targets over a simulated battlefield and firing while airborne under human control. The reporting gives no accuracy results, customers or orders.
What the Fire Storm 250 Test Showed
In the announced demonstration, the Fire Storm 250 hovered over a simulated battlefield, identified targets using an onboard camera, and fired the M250 machine gun in single-shot and semi-automatic modes. It fired at varying distances and altitudes.
The weapon was installed on a stabilized mount integrated into a 53-pound remote-controlled weapon system (RCWS). Both companies stated that sensor information and fire-control data combined into a unified targeting solution.
The Defense News article does not state where the test took place.
Flight and Payload Specifications
The Fire Storm 250 is an aerial platform with stated specs including vertical takeoff and landing. Per Janes, the aircraft uses an internal combustion engine compatible with multiple jet fuels, allowing field reuse.
Janes reported two hours airborne. The stated specs per Janes include an ammunition capacity of 200 rounds alongside the 53-pound remote weapon mount.
| Item | Stated figure | Source and notes |
|---|---|---|
| Aircraft configuration | Heavy-duty quadcopter | Vertical takeoff and landing; reusable |
| Flight endurance | Two hours | Reported by Janes |
| Propulsion | Internal combustion engine | Runs on various jet fuels (per Janes) |
| Weapon mount | 53 pounds | Stabilized remote-controlled weapon system |
| Ammunition load | 200 rounds | Stated ammunition capacity |
| Primary armament | Sig Sauer M250 | Operated in single-shot and semi-automatic modes |
The M250 Weapon System and Cartridge Options
The primary armament tested on the drone is the Sig Sauer M250, a belt-fed light machine gun set to replace the legacy M249 squad automatic weapon under the Army's Next-Generation Squad Weapon (NGSW) program. Sali Okanin, Israel General Manager for Sig Sauer, described the weapon as a belt-fed platform with greater range than legacy systems.
The U.S. Army's M250 is chambered for Sig Sauer's 6.8x51mm cartridge, whereas the Israel Defense Forces have operated a 7.62x51mm variant since 2025. Reporting indicates that the Fire Storm 250 can carry either caliber.
Targeting Architecture and Human-in-the-Loop Control
IAI and Sig Sauer highlighted that operators make engagement and firing decisions using imagery and tracking data from onboard sensors.
Earlier reporting said AI automates some tracking and detection components. Even so, the companies emphasized that human operators make engagement and firing decisions.
Project Timeline and Fielding Expectations
IAI first unveiled the Fire Storm 250 in October 2025. In February 2026, Janes reported that flight tests for the platform were scheduled for summer 2026. The firing test was announced October 13, 2026.
Sig Sauer executives expect fielding of the M250 itself to begin in the first half of 2027.
Unconfirmed Operational Details
The announcement said the drone fired in single-shot and semi-automatic modes, but the Defense News article gives no hit rates, ranges or accuracy results.
The reporting did not clarify whether burst or fully automatic firing modes were tested.
The Defense News article does not give price, aircraft weight, orders, customers, export status or any military requirement for an armed drone of this type.
What Would Change This Read
Three developments would change this read:
First, published accuracy data from the firing test.
Second, a named customer or order.
Third, an Army requirement for an armed drone of this type.
