US-based Archer Aviation has signed definitive agreements to acquire Boeing subsidiaries Wisk Aero, SkyGrid and Insitu, aiming to expand its capabilities in physical AI technology. The agreement will see Archer integrate the autonomous flight expertise developed by Wisk over 16 years, SkyGrid’s digital air traffic management tools and Insitu’s unmanned aircraft systems (UAS) portfolio, which has seen extensive deployment with armed forces in 35 nations. Boeing will retain access to Wisk’s core autonomous flight technology for its own commercial and defence aircraft, and will maintain a stake in Archer, allowing it to benefit from future developments.
