Nothing motivates me more in acquiring weapons for the Air Force than foreign military threats. Stealth fighters, satellite-guided missiles, and silent submarines were once unique US capabilities; now our troops must face them on future battlefields.

I’m also deeply motivated by lessons of the past, including the stymying effect late-to-post-Cold War weapons buying had on the defense industry, especially aviation. In the late 1950s, over a dozen companies built fighter jets called the Century Series that pushed boundaries of supersonic flight. Competing against the Soviet Union when air power was in flux, and deciding which new airplane would be the right one was uncertain, these companies built the F-100 through F-106 in just a few short years. Now we have only two companies building front-line fighters.
The pace of new defense programs is one of the casualties of reduced competition. Even in the 1970s, new military airplanes rolled out every four to five years. But the tech slowdown of the late Cold War—where nearly every aircraft system completely computerized—triggered a withering domino effect: Defense programs slowed from years to decades, profit shifted predominantly to production and upkeep, and companies merged (and still merge) to diversify their portfolios to remain competitive.
This was likely unavoidable, even necessary, to win the Cold War, but we will lose the current competition against China and Russia if it remains status quo. The tech speed-up we’re experiencing now in the digital age could trigger a burgeoning domino effect that speeds up programs, shifts more profit into design, and brings new companies into defense. But this will only happen if the Pentagon and its pundits think outside our five-sided building before it becomes a coffin of dead innovation.
That’s why I’m thrilled about three converging technologies—what I call the digital “holy trinity”—that are revolutionizing commercial industry and beginning to trend in defense: open systems design, agile cloud-based software, and digital engineering. Though not as hashtaggable as lasers, hypersonics, or spaceplanes, this trinity creates the opportunity for a miraculous new weapons-building process that is far more exciting.
Following similar digital transformation trends as the automotive and other commercial industries, we’re applying the trinity to our future “6th Generation” Fighter, creating what you might call a “Digital Century Series.” The core idea is replacing paper design and process with virtually-realistic models, called “digital twins” and “digital threads,” where all phases—design, assembly, flight, and even maintenance—are modeled so accurately we can digitally reduce overhead, labor, tooling, training, and learning-curve mistakes as if we had already built and debugged 100 units. “Fly before you buy”—a painstaking and in some cases time-consuming process of prototyping and flight testing—has been our troubleshooting mantra since the 1970s. This digital holy trinity will hopefully add a new line of defense acquisition scripture in a dawning era of digitally conceived ePlanes: “eDesign before you Fly.”
