The B-29 Superfortress went from signed contract to combat mission in forty-six months. It was, at the time, the most complex machine ever put into mass production — pressurized cabin, remote-controlled gun turrets, four engines pushing technology barely out of the prototype stage — and the country building it still managed to field 3,970 of them before the war that demanded them was over. In 1944 alone, American factories produced 96,270 aircraft of every type. That is not a typo, and it is not ancient history romanticized by distance. It is a documented industrial fact about what this country used to be able to do in a single calendar year.

The B-21 Raider, America's newest stealth bomber, received its development contract in 2015 and first flew in 2023 — eight years, against the B-29's twenty-five months from contract to first flight. It's expected to enter service around 2026 or 2027, at a reported production rate of seven to eight aircraft a year. At that pace, matching the B-29's wartime fleet size would take roughly five centuries.

The Same Building, A Different Country

There's a detail here worth sitting with rather than rushing past: F-35 final assembly is housed at a mile-long facility in Fort Worth, Texas, nicknamed the "bomber plant" because it once turned out warplanes by the thousands for the Army Air Corps. Same building, same purpose in the broadest sense, radically different output. It isn't a story about the building losing some capability it used to have. It's a story about what got built inside it changing shape — fewer, far more expensive, far more capable machines, replacing a philosophy of overwhelming numbers with a philosophy of overwhelming sophistication.

Lockheed delivered a record 191 F-35s in 2025, and it's worth being honest about what that record actually represents before treating it as evidence the system is healthy. The stable target rate has held near 156 a year for some time. And of the aircraft the Department of Defense is actually requesting for the U.S. military in the coming budget, the number is 85 — well under half the total headline figure, with the rest of that "record year" built for export to allied nations. The production line is busy. Global demand is real. But the slice of that busyness feeding America's own Air Force is a much smaller number than the press release leads with.

Complexity as the Design Choice

None of this happened by accident or through simple neglect. Every generation of American combat aircraft since the B-29 has traded producibility for capability on purpose, as a matter of stated doctrine — fewer airframes, each one carrying more of what a fight is assumed to require: stealth, sensor fusion, networked data-sharing, systems integration across a dozen subcontractors that a 1944 production line never had to coordinate. That trade wasn't unreasonable in a world where America expected to fight short, technologically lopsided wars against adversaries who couldn't match the sophistication. It becomes a liability in exactly the scenario this series keeps returning to: a longer fight, against an adversary capable of attrition, where the number of airframes matters as much as what any single one of them can do.

A defense-industrial system that can build sophistication faster than it can track what the sophistication costs.

The F-35's own numbers make the trade explicit. Lifetime sustainment costs for the program have already grown from roughly $1.1 trillion to $1.58 trillion by the government's own accounting — a 44 percent increase over a single set of revised projections, on an obligation that stretches to the year 2088. That is not a production problem. It's a preview of the next chapter's problem.

Next: the wafer nobody in this country can make enough of, and the reason has almost nothing to do with the war effort this time.

To Whom It May Concern —

This piece was produced through a collaboration between a human author and an AI system (Claude, made by Anthropic). The research, structure, and editorial judgment are a joint effort; errors, once found, are corrected openly rather than quietly revised away. We think that collaboration is worth being honest about, so we are.
