That's not the only party trick, either. An array of lights on the back of the Striker II help guide a head-tracking system that keeps projected information in close sync with head movements; a pilot caught in a dogfight won't have to wait crucial moments for flight info to drift into view. The gotcha for any aspiring aces? BAE hasn't said just when it expects the Striker II to go into service, or who might be a customer. The original Striker is currently in use by air forces flying Eurofighter Typhoons and Saab Gripens, though, so it makes sense that they'd be some of the first to line up.
