Centaur

Centaur is an autonomous flight-control system from Helsing , the European defence-software company best known for its battlefield AI and strike drones. Where most of Helsing’s portfolio sits on the ground or in small unmanned aircraft, Centaur targets crewed combat aviation: it is an AI “pilot” trained to fly and fight a fighter jet, intended to operate alongside or in place of a human in the cockpit. It moved from simulator to real airframe in 2024, when Helsing and Saab announced a partnership to integrate it into the Gripen E test programme in Sweden.

The system is built on deep reinforcement learning. Helsing has described training Centaur across millions of simulated engagements, letting the agent discover tactics rather than scripting them. The output is a policy that ingests sensor and state data and emits stick-and-throttle-level commands at the rates a fighter requires. Centaur runs on standard mission-computer hardware rather than a bespoke autopilot, and during the Saab campaign it was hooked into the Gripen E’s flight controls through a software interface that lets a safety pilot intervene at any moment. The reinforcement-learning approach allows the agent to be re-trained against new threat models and weapons loadouts without rewriting the underlying code — a deliberate contrast with the hand-tuned control laws of legacy autopilots.

Sweden is the first operator to put Centaur in the air. Saab flew Gripen E test sorties with Centaur in command, including beyond-visual-range engagement scenarios against another Gripen acting as an adversary. Saab’s chief test pilot reported that the AI carried out the engagements without intervention. No production contracts have been announced; the work to date is a development partnership rather than a fielded capability, and Helsing has not disclosed which other air forces, if any, are evaluating the software.

Centaur sits inside a wider race to put AI into crewed and uncrewed fighters. The United States has pursued the same goal through DARPA’s Air Combat Evolution programme and the Air Force’s Collaborative Combat Aircraft effort, and Lockheed Martin’s Skunk Works has flown autonomy on an F-16 testbed under the VISTA programme. What distinguishes Centaur is its European origin and its focus on a generation-4.5 platform already in series production rather than on a future loyal-wingman drone. For Helsing, a company that began on the ground-truth side of battlefield software, the Saab partnership is its most visible move into air combat — and an early test of whether a software house can deliver the autonomy layer for a fighter built by someone else.
