Between BAE and Rockwell Collins seeing a lot of innovation in these HDMS Systems with DNVG, is it a coincidence? F-35 Gen III Helmet Mounted Display System delivered for software integration to Lockheed Martin

The HMD has a biocular 40x30 degrees field-of-view, high brightness, and high resolution display, with integrated digital night vision. The HMDS displays the Distributed Aperture System (DAS) imagery from Northrop Grumman, which provides pilots with the ability to see through the structure of the aircraft for a 360-degree view as well as a direct picture of the ground beneath them.
