When Lockheed Martin began developing the F-35 in 2001, several technologies needed for the Joint Strike Fighter (JSF) to succeed were far from ready. One was a revolution in helmet-display technology. The goal was to combine the functionality of head-up and head-down displays and a helmet-mounted cueing system into a single helmet for the F-35 pilot. But Vision Systems International (VSI), a Rockwell Collins/Elbit Systems joint venture, encountered some thorny issues while maturing the technology. VSI is now incorporating lessons from tests that were added to the JSF program last year. Those 42 flights over six months, involving all three F-35 variants, were dedicated to pinpointing what improvements were needed to bring the "Gen 2" helmet-now being used in testing and training-up to a fully compliant Gen 3 standard.
