Boeing has integrated Vision Systems International's Joint Helmet Mounted Cueing System II/h (JHMCS II/h) on the F-15 Silent Eagle demonstrator aircraft.
"The JHMCS II/h allows a pilot to aim sensors and weapons wherever he or she is looking, through the use of new head-tracking technology and a display projected onto the helmet's visor," said Boeing in a statement.
A recent flight near St Louis, Missouri, collected data about the system, which took less than three months to integrate into the aircraft.
"Both pilots who flew with the JHMCS II/h system immediately noticed that the helmet was more balanced and the smaller, lighter interface cable was less restrictive," said Greg Hardy, Boeing JHMCS programme manager.
Boeing is pitching the Silent Eagle against the Lockheed Martin F-35A Joint Strike Fighter and the Eurofighter consortium's Typhoon in South Korea's F-X III competition for 60 aircraft.
