For two years the jets sat in a hangar at Eglin Air Force Base while engineers tore into their airframes and taught them to think. This week one of them finally flew — and for stretches of that flight, no human was flying it.

The U.S. Air Force and DARPA have put the first F-16 fitted with the VENOM Autonomy Kit into the air with an artificial-intelligence agent doing the actual flying, a test pilot riding along only to watch. It is the moment the Pentagon’s long, careful march toward robot fighters stopped being a simulation and became a real jet over the Florida panhandle.

Two years of surgery, one historic sortie

The idea is deceptively simple: take a combat-proven fighter, wire in a computer that can fly it, and use the jet as a flying laboratory for the software that will one day pilot pilotless aircraft. The hard part is doing it without killing anyone.

Three F-16s arrived at Eglin in 2024 and 2025 to be rebuilt into testbeds under VENOM-AFT, handed to the 96th Test Wing and the 53rd Wing. The jets began flying again in June to prove they were still airworthy after the modifications. Then, in July, the team crossed the line that matters: an AI agent took control in the air and flew the aircraft itself, with the human on board shifting from pilot to supervisor.

This is not a drone conversion in the drop-the-cockpit sense. The pilot stays. What changes is who has the stick for a given test point, and how quickly the Air Force can throw new autonomy software at a real aircraft and see whether it holds up in the messy physics of actual flight.

The human never leaves the loop

The word the Air Force keeps repeating is “human-on-the-loop.” It means a pilot is always present, watching the algorithms work and holding the authority to start or stop any one of them in real time. VENOM is not about empty cockpits — not yet.

That caution is the whole point. The faster the Air Force can prove an autonomy behaviour is safe on a crewed F-16, the faster it can trust that same code on an uncrewed one. Gagnon has described the goal as “speed-to-ramp” — going as fast as is safely possible so the drones that follow arrive sooner.

Why a 1970s fighter is teaching tomorrow’s drones

VENOM feeds directly into the Collaborative Combat Aircraft program, the fleet of cheap, semi-autonomous drone wingmen the Air Force wants flying alongside the F-35 and the future F-47. Every lesson the F-16 testbeds return — how an AI handles a merge, a formation, a weapons pass — is a lesson the CCAs inherit.

The groundwork was laid by DARPA’s ACE program and its X-62A VISTA jet, which in September 2023 flew the first-ever within-visual-range dogfight between an AI-controlled F-16 and a human-flown one. VENOM takes that proof of concept and turns it into a repeatable production line for autonomy testing on ordinary front-line jets.

Two years ago this was PowerPoint and simulation. This week it was a grey Fighting Falcon climbing away from Eglin, flying itself, with a human along for the ride. The robots are not replacing the pilot yet. But they are learning fast — and they are learning in the real sky now.

DARPA’s AI agents fly an F-16 against a human pilot — the ACE work that laid the groundwork for VENOM.
