AFRICOM's CURTAIN CALL Swarm Cleared A Harder Test. Confirmed Kills Weren't The Point.
AI Analysis
U.S. AFRICOM successfully completed a second field test of its CURTAIN CALL counter-drone swarm system at Lawrence Livermore National Laboratory, focusing on coordinated drone attacks. While the system demonstrated improved tracking and rapid response capabilities, including successful communication with the defensive swarm and integration with TAK software, no confirmed intercept counts were released. The test highlighted the ongoing challenge of reliably and affordably neutralizing drone swarms.
Key Takeaways
- CURTAIN CALL is designed to create a defensive 'wall' of drones to intercept incoming threats.
- The second test involved both single drone and coordinated multi-drone attack scenarios.
- The system achieved near real-time threat detection, tracking, and cueing of the defensive swarm.
- A key operational goal met was the integration of the Tactical Awareness Kit (TAK) for enhanced situational awareness.
- AFRICOM acknowledges that reliably intercepting drones, especially in a swarm, at a cost-effective price remains a significant challenge.
Why It Matters
The development of effective counter-swarm technology is critical given the increasing use of drone swarms in modern conflicts, as seen in Ukraine and the Middle East. CURTAIN CALL's progress towards a deployable, low-cost defensive layer is significant, but the lack of confirmed intercepts underscores the persistent technological hurdles. This highlights the need for continued investment and innovation in both offensive and defensive drone capabilities.

U.S. Africa Command ran its CURTAIN CALL drone-swarm defense through a second field test at Lawrence Livermore National Laboratory in California from April 27 to May 1, 2026, and this round added the threat the program was built to stop: a coordinated attack by several drones at once, not a single aircraft.
What the command reported is narrower than the “defeat coordinated UAV attacks” framing now circulating. AFRICOM said the system detected and tracked the threats and cued a defensive swarm in near real time, with its communication and command links holding together. Then it logged where it fell short. No confirmed intercept count was released. That distinction matters, because every counter-drone program I have covered this year runs into the same wall. Tracking a swarm is the cheap part. Knocking one down reliably, at a price that beats the attacker’s, is the part nobody has fully solved.
The second test pointed the system at a coordinated attack
AFRICOM built CURTAIN CALL to throw a fast, synchronized wall of drones in front of incoming threats, and the five-day Livermore event tested that idea against both a lone drone and a coordinated multi-drone strike, the saturation tactic that has defined aerial combat from Ukraine to the Middle East.
The results, according to AFRICOM, showed the system tracking the threats and reacting faster than it did in the program’s first demonstration at the same Livermore site, which AFRICOM detailed in February. Under the concept, sensors and cameras watch the airspace, flag a possible threat, and alert a human operator who decides whether to engage. Once that operator approves, the defensive swarm launches to form an interception barrier in front of whatever is inbound. A human keeps the authority to fire.
“Our first demonstration gave us initial technical feasibility insights; this second event brought the concept to life in a controlled environment,” said U.S. Air Force Lt. Col. Jared Bindl, AFRICOM’s chief innovation officer. The team, he said, tracked coordinated threats and provided near real-time cueing of the defensive swarm, which he framed as inching the project closer to a deployable, low-cost defensive layer.
What CURTAIN CALL validated, and where it came up short
Beyond tracking, the command reported meeting a set of operational goals during the five-day test:
- Direct communication with the drone swarm, the link that lets defensive drones receive targeting data and respond as threat conditions change.
- Launching the swarm into action the moment a human operator approved the engagement, compressing the response timeline against fast-moving targets.
- Integration of the Tactical Awareness Kit (TAK), the situational-awareness software used across U.S. and partner forces, which gave operators a visual picture of the th
