The U.S. Army recently provided the following definition for "digital engineering," in the article "A Matter of Course," that explains how the Army is developing a new digital engineering course. Here's how the Army describes digital engineering:

"Digital engineering is the process of digitally designing military equipment, such as future combat vehicles or other military hardware, to be designed and built in a virtual environment where it can be tested, analyzed and can engage with Soldiers before a single piece of iron is bent to build the prototype. While digital engineering has become the norm in many commercial manufacturing settings, it is still a relatively new concept to the Army, and this knowledge gap has created a need for professional education inside the force."

On the second episode of Season 4, we highlight some of the digital transformation and new digital technologies and capabilities being developed and adopted by three of the largest aerospace and defense manufacturers in the world, including Lockheed Martin, Northrop Grumman and Raytheon. The chief executives from each of these industry giants highlighted show they're using digital design tools, developing new digital capabilities and adopting artificial intelligence (AI) during their respective second quarter earnings calls.
