June 2016 - the proof is in the firing. Footage from the first ever firings of a Brimstone missile from an Apache AH-64E. Fired from a M299 launcher, and using a telemetry missile with no warhead, this proves Brimstone can be integrated on to an Apache.
The highly regarded Brimstone precision is clearly seen. A Boeing flight test engineer who witnessed the trials said, The mmW autonomous shot from a moving and banking platform against an off-axis target with the missile hitting the tanks turret ring was the most aggressive shot I have ever seen in my 30 years of the Apache programme.
