Shield AI aims to integrate Aechelon Technology's simulation and training tools into its autonomous software ecosystem called Hivemind.
Shield AI, a maker of artificial intelligence-centric software to operate autonomous vehicles and other systems, has completed a $1.5 billion Series G capital raise with some of the proceeds going toward a planned acquisition.
Aechelon Technology is an image generation and simulation software developer that opened for business in 1998. The software is designed to help enable full-flight aircraft simulators for training military pilots and testing uncrewed aircraft before live flight.
Through this acquisition announced Thursday, Shield AI is looking to integrate Aechelon’s high-fidelity simulation and other related applications into the former’s Hivemind software ecosystem for enabling autonomous operations. Financial terms of the transaction were not disclosed.
Hivemind is a flagship offering of Shield AI alongside its V-BAT and X-BAT drones. A portion of the Series G proceeds will also support efforts to further develop and deliver those vehicles.
For Aechelon, its pending sale comes less than two years after private equity firm Sagewind Capital acquired majority ownership of the company. Aechelon provides simulation technology to the U.S. military’s Joint Simulation Environment, which is used to test and validate autonomous systems and combat aircraft.
Shield AI previously closed a $240 million Series F-1 round in March 2025 that included L3Harris Technologies as a new investor.
Both that and the Series G round highlight investor interest in defense tech companies that specialize in AI and autonomy as militaries around the world, including
