FARNBOURGH AIR SHOW: When Lockheed Martin bumped North Grumman’s Disgtributed Aperture System from the F-35 program in favor one offered by Raytheon, analysts were shocked.

it largely drove Northrop out of a significant segment of the electro-optical sensor market and was believed to significantly reduce the company’s revenue over the life of the F-35.

Greg Ulmer, the new head of Lockheed’s F-35 program, describes here why the company went with Raytheon’s sensor. He offered new details about it, noting it weighs less than Northrop’s and uses less power than does the current version.
