Battlefield trial begins as Phantom MK-1 humanoid robots reach Ukraine

Two soldier robots have been delivered to Ukraine for battlefield evaluation, marking a new step in the development of robotic combat systems.

The humanoid Phantom MK-1 robots were sent by the US startup Foundation in February, according to the company.

Ukraine has increasingly become a real-world testing ground for emerging military technologies, attracting defense firms and startups from the West.

The San Francisco-based robotics firm plans to deploy the humanoid robots closer to the front line to refine their capabilities.

In October 2025, Foundation unveiled the Phantom MK-1, a humanoid robot designed specifically for combat and believed to be among the first built for warfare.

War tests humanoids

Foundation revealed that humanoid robots have already been sent to Ukraine for battlefield evaluation, highlighting the growing role of robotics in modern warfare.

In a recent interview with Time, Foundation co-founder Mike LeBlanc said the company deployed two Phantom Mk-I humanoid robots to Ukraine in February. The robots were sent to the frontline for reconnaissance as part of efforts to test the platform in a real combat environment, reports Futurism.

Foundation unveiled the Phantom Mk-I in October 2025, describing it as a humanoid robot designed specifically for military use. The deployment could represent the first known instance of a humanoid robot being tested on the front lines of the ongoing Russia–Ukraine War.

LeBlanc said the company believes robots could eventually perform dangerous battlefield roles currently carried out by soldiers. He added that the Phantom platform is being developed to handle a range of weapons systems typically used by humans.

The Mk-I is already undergoing trials in industrial facilities worldwide, but Ukraine has become a key testing ground for emerging military technologies. According to Ukraine’s state news agency United24, the country conducted thousands of robotic operations in January alone, most focused on logistics such as delivering ammunition, weapons, and supplies to frontline troops, reports Futurism.

The company is also in close contact with the US Department of Homeland Security about the potential use of Phantom robots for patrol operations along the southern border, reports Militarnyi.

Military robot surge

Foundation is accelerating the development of military-capable humanoid robots, with plans to manufacture up to 50,000 units by the end of 2027.

The company’s Phantom MK-1 is designed for both industrial and defense roles, positioning it among a small group of robotics systems targeting dual-use applications. The humanoid stands about 5 feet 9 inches tall, weighs roughly 175–180 pounds (79–82 kilograms), and is intended for tasks such as reconnaissance, bomb disposal, and other high-risk ground operations.

The robot is built to operate in dangerous environments where sending human personnel may be unsafe. Potential battlefield roles include surveillance, logistics support, and handling hazardous materials during military missions.

Production plans call for an initial deployment of dozens of units this year, scaling to thousands annually as manufacturing capacity expands. The company plans to lease the robots rather than sell them outright, with estimated annual leasing costs of around $100,000 per unit. Continuous operation could allow a single robot to replace multiple human work shifts in industrial settings.

Technically, the Phantom MK-1 relies primarily on camera-based vision systems rather than complex sensor arrays like LiDAR. It also uses proprietary cycloid actuators that deliver strength, quiet operation, and backdrivability for safer human interaction.

The system is designed with human-in-the-loop control, where robots manage movement and navigation while human operators retain authority over any lethal decisions.
