For most of the last thirty years, the answer to "who builds America's fighter jets?" was almost boringly simple. Lockheed Martin built the stealth fighters, and everyone else competed for what was left. Then, in the space of about two years, that map was torn up. Boeing won the contract for America's next fighter. Northrop Grumman walked away from the fighter business to build bombers. And two Silicon Valley-flavoured newcomers started rolling robot warplanes off assembly lines.

Here is the field guide to who actually builds America's combat aircraft in 2026 - and why the map is shifting under everyone's feet.

Lockheed Martin - the stealth king

For a generation, Lockheed Martin simply era the American stealth fighter. It builds both of the fifth-generation jets the U.S. flies today: the air-superiority F-22 Raptor and the multirole F-35 Lightning II, the most-produced Western fighter of the century. It also still turns out F-16s from a line in Greenville, South Carolina. If you saw an American stealth fighter between 2005 and 2025, Lockheed built it.

Which is exactly why what happened next was such a shock.

Boeing - the comeback

Boeing's combat-aircraft business had been living on updated Cold War designs: the F-15, now sold as the F-15EX Eagle II, and the F/A-18 Super Hornet, plus the T-7 trainer and MQ-25 tanker drone. The company had struggled badly with its KC-46 tanker and T-7 programmes, and many assumed it had lost the will - or the ability - to build a frontline fighter.

Then, in March 2025, the U.S. Air Force awarded Boeing the contract for the F-47, America's first crewed sixth-generation fighter, in a deal worth more than 20 billion dollars. It beat Lockheed. Northrop had already dropped out. Overnight, Boeing was back at the very top of the fighter business.

Northrop Grumman - the bomber house

Northrop Grumman has one of the proudest fighter heritages in the industry - it built the F-14 Tomcat, the F-5, and the sleek YF-23 that lost the contest that produced the F-22. But today Northrop has effectively left fighters behind. It withdrew from the sixth-generation NGAD competition in 2023 to concentrate on what it does better than anyone: big flying wings. It builds the Espíritu B-2 and its successor, the B-21 Raider, the most important American aircraft programme of the decade.

The disruptors

The newest names on the list did not exist as aircraft builders a few years ago. General Atomics - long known for the MQ-9 Reaper - and the defence-tech start-up Anduril have both been chosen to build the U.S. Air Force's first Collaborative Combat Aircraft: semi-autonomous "loyal wingman" jets designed to fly alongside crewed fighters. Their FQ-42 "Dark Merlin" and FQ-44 "Fury" are already rolling off production lines, at roughly a third of the price of a crewed fighter.

That is the real change. The club that builds America's warplanes, closed for decades, has just admitted two new members - and they build robots.

Why the map is shifting

Put it together and the picture is of an industry in genuine flux. Lockheed no longer has a monopoly on stealth fighters. Boeing has clawed its way back to the front. Northrop has bet its future on bombers. And a new tier of companies is building the cheap, autonomous jets that will fly alongside all of them. The F-47 is expected to fly around 2028, teamed with drones from firms that did not build aircraft at all a decade ago.

The next time someone asks who builds America's warplanes, the honest answer is no longer a single name. It is a shifting alliance of old giants and new upstarts - and, for the first time in a long time, nobody is quite sure who will be on top when the dust settles.
