The US Army has named Allen Control Systems (ACS)’ autonomous overwatch system Bullfrog a winner of its xTechOverwatch competition.
ACS will receive a $2-million Direct to Phase II Small Business Innovation Research award to accelerate Bullfrog’s development.
Bullfrog was selected from dozens of advanced defense technology submissions after rigorous evaluation of real‑world performance, technical innovation, and potential scalability across army formations.
The autonomous system layers artificial intelligence, computer vision, and proprietary control algorithms onto legacy or modern weapons. It is designed to enhance precision engagements and provide ground forces greater capability against evolving unmanned aerial threats.
ACS co-founder and CEO Mike Wior said that Bullfrog fills gaps where traditional systems fall short by enabling rapid autonomous counter‑drone performance tailored to maneuver forces, aligning with the army’s wider Transformation in Contact initiatives.
xTechOverwatch Autonomous Innovation
Since its launch in April 2025, xTechOverwatch has become a central venue for the army to identify and advance cutting‑edge autonomous capabilities among small businesses.
The competition received more than 600 submissions and 40 finalists were showcased at the October 2025 finals.
Among the diversified set of winners, several companies stood out for technologies supporting tactical autonomy beyond counter‑drone systems.
Scout AI won for its Fury autonomous agent, which uses a learned vision‑language‑action model to support navigation, intelligence, surveillance, and multi‑robot coordination in complex environments.
TERN, meanwhile, was recognized for its AI‑powered Independently Derived Positioning System, which provides secure, satellite‑free navigation, even in contested environments.
Multiple other firms were acknowledged in the competition for advancing autonomous capabilities.
Companies like FieldAI Federal have developed autonomy stacks that enable robotic systems to navigate unstructured terrain without GPS, while AZAK was recognized for resilient robotics adapted to uneven terrain.
Swarmbotics AI — another xTechOverwatch competitor — moved its autonomous ground robotics performance into a follow-on army contract to build swarming, attritable unmanned ground vehicles for the 1st Cavalry Division.
Competitions like xTechOverwatch aim to accelerate the transition of autonomous systems from prototype to operational use, reducing development timelines and rapidly integrating new capabilities into combined arms formations.
