Foundation Phantom MK-1 is a US-built biped humanoid (5'9", 176 lb, 44 lb payload, 1.7 m/s, camera-first no LiDAR) reported to have 19 upper-body DOF and a reported lease price around $100,000/year. Its strongest evidence is a media-reported deployment of two units to Ukraine in February 2026 for logistics and reconnaissance testing, plus $24M in Pentagon research contracts. Industrial claims include factory/dockyard testing and a Foundation claim via Reuters of helping build over 24,000 cars in 2025. However, all evidence is media-mediated company claims; no official government/customer release, no independent benchmark, and no video transcript were reviewed. Major spec conflicts exist on battery/runtime, fall recovery, and arm/hand function, and the robot is not publicly purchasable
