Allen Control Systems (ACS) has completed a live demonstration of its robotic weapon station, Bullfrog, during the U.S. Army’s Project Convergence Capstone 5 (PCC5), held at Fort Irwin, California, from February 26 to March 16. The system was used to autonomously detect and engage a drone swarm in one of its most complex operational scenarios to date.
Bullfrog is designed to retrofit both modern and legacy weapons with autonomous targeting capabilities using AI, computer vision and proprietary control systems. The goal, according to ACS, is to enhance precision and responsiveness when facing unmanned threats. During PCC5, Bullfrog engaged and reportedly neutralized seven drone targets in a breach scenario – its largest autonomous engagement thus far.
The event provided an opportunity for ACS to test Bullfrog’s capabilities under field conditions. Although full scenario flexibility was limited by environmental constraints, ACS claims the system performed consistently across a range of metrics, including autonomous threat detection, operator onboarding, and rapid deployment.
One notable aspect of the trial was Bullfrog’s training curve. According to ACS, over 40 soldiers from various Military Occupational Specialties were trained to operate the system in under 30 minutes. The system also transitioned from storage to operational use in under two minutes, potentially offering rapid-response utility in fast-moving engagements.
All engagements were independently adjudicated by U.S. Army evaluators, with Sidewinder 20 and CPT Allison Carlisle overseeing the breach scenario in which Bullfrog was tested.
ACS positions Bullfrog as a lower-cost alternative to conventional counter-unmanned system (C-UxS) technologies by adapting existing weapons platforms. However, the company did not disclose which weapon types were used in the demonstration, nor did it provide footage or third-party assessments of performance during the exercise.
While the system’s real-world viability remains subject to further testing and evaluation, ACS sees Bullfrog as a step toward more autonomous, cost-efficient counter-drone solutions. The company also noted that feedback from the exercise will inform future improvements, particularly in target-switching, durability, and low-light performance.
Project Convergence is the U.S. Army’s premier modernization exercise, aimed at testing emerging technologies across a range of domains and scenarios to support future joint operations.
