Aechelon's technology creates the virtual environments used by the U.S. military and allies to train aircrew and test aircraft and autonomous systems before live flight, including support for the Pentagon's Joint Simulation Environment (JSE). Shield AI develops Hivemind, an AI autonomy software that operates military vehicles including F-16s, jet-powered UAVs and helicopters. By acquiring Aechelon, Shield AI brings simulation capability in-house to train and refine Hivemind more effectively. "The acquisition of Aechelon will accelerate the work we are doing with Hivemind, particularly in simulation like the Department of War's JSE," said Shield AI CEO Gary Steele. "It will also help advance our Hivemind Foundation Model for Defense, which is trained in simulation and continuously refined through real-world operations." Hivemind was recently selected by the U.S. Air Force as a mission autonomy provider for Collaborative Combat Aircraft (CCA). The $1.5 billion Series G values Shield AI at $12.7 billion and is led by Advent International, co-led by JPMorganChase's Security and Resiliency Initiative, with participation from Snowpoint Ventures, InnovationX and Riot Ventures. Funds managed by Blackstone are separately providing $500 million in preferred equity financing, plus a $250 million delayed draw facility. The Aechelon acquisition is expected to close following regulatory approvals. FREE NEWSLETTERS The world's leading authority of safety training news!
