Skunk Works

Kelly Johnson was regarded almost as a deity at the CIA, and I had him carry our request for disclosure to the director’s office. To my amazement, the agency cooperated immediately by supplying all our previously highly classified radar-cross-section test results, which I sent on to Dr. George Heilmeier, the head of DARPA (the Defense Department’s Advanced Research Projects Agency), together with a formal request to enter the stealth competition. But Dr. Heilmeier called me, expressing regrets. “Ben, I only wish I had known about this sooner. You’re way too late. We’ve given out all the money to the five competitors.” The only possibility, he thought, would be to allow us to enter if we would agree to a one dollar pro forma government contract. As it turned out, if I had done nothing more that first year than refuse that one dollar offer, I had more than earned my salary. I was sitting on a major technological breakthrough, and if I took that government buck, the Feds would own the rights to all our equations, shapes, composites—the works. Lockheed was taking the risks, we deserved the future profits.

It took a lot of arguing at my end, but Dr. Heilmeier finally agreed to let us into the stealth competition with no strings attached, and it was the only time I actually felt good about not receiving a government contract. But not Kelly. “You’re wasting your time,” he told me. “This is like chasing a butterfly in a rain forest because in the end the government won’t invest big dollars in stealth, when for the same money they can invest in new missiles.”

In part, I think, Kelly was trying to be protective. He didn’t want me to risk an embarrassing failure my first turn at bat, pursuing a high-risk project with little apparent long-range potential. I would be spending close to a million dollars of our own development money on this project, and if Kelly was right, I’d wind up with nothing to show for it. Still, I never waivered from believing that stealth could create the biggest Skunk Works bonanza ever. It was a risk well worth taking, proving a technology that could dominate military aviation in the 1980s even more than the U-2 spy plane had impacted the 1950s. At that point the Russians had no satellites or long-range airplanes that could match our missions and overfly us. Stealth would land the Russians on their ear. They had no technology in development that could cope with it. So I resolved to see this project through, even if it meant an early fall from grace. My department heads would go along because they loved high-stakes challenges, with most of the risks falling on the boss. I confided my stealth ambitions to Lockheed’s new president, Larry Kitchen, who was himself dancing barefoot on live coals while trying to pull our corporation up to a standing position after the pulverizing year and a half of scandals and bankruptcy. Larry cautioned me: “We need real projects, not pipedreams, Ben. If you’ve got to take risks, at least make sure you keep it cheap, so I can back you without getting my own head handed to me. And if something goes sour, I want to be the first to know. My blessings.” Good man, Larry Kitchen. After all, he had also approved hiring me as Kelly’s successor.

Denys Overholser reported back to me on May 5, 1975, on his attempts to design the stealthiest shape for the competition. He was wearing a confident smile as he sat down on the couch in my office with a preliminary designer named Dick Scherrer, who had helped him sketch out the ultimate stealth shape that would result in the lowest radar observability from every angle. What emerged was a diamond beveled in four directions, creating in essence four triangles. Viewed from above the design closely resembled an Indian arrowhead.

Denys was a hearty outdoorsman, a cross-country ski addict and avid mountain biker, a terrific fellow generally, but inexplicably fascinated by radomes and radar. That was his specialty, designing radomes—the jet’s nose cone made out of noninterfering composites, housing its radar tracking system. It was an obscure, arcane specialty, and Denys was the best there was. He loved solving radar problems the way that some people love crossword puzzles.

“Boss,” he said, handing me the diamond-shaped sketch, “Meet the Hopeless Diamond.”

“How good are your radar-cross-section numbers on this one?” I asked.

“Pretty good.” Denys grinned impishly. “Ask me, ‘How good?’ ”

I asked him and he told me. “This shape is one thousand times less visible than the least visible shape previously produced at the Skunk Works.”

“Whoa!” I exclaimed. “Are you telling me that this shape is a thousand times less visible than the D-21 drone?”

“You’ve got it!” Denys exclaimed.

“If we made this shape into a full-size tactical fighter, what would be its equivalent radar signature… as big as what—a Piper Cub, a T-38 trainer… what?”
