The 3 Billion Gamble of WW2 — The B-29

What was the most expensive American project of World War II? Not the atomic bomb.

It introduced pressurized cabins, remote-controlled gun turrets, and advanced fire-control computers, making it one of the most technologically ambitious aircraft ever built. The bomb changed history. But the B-29 was the machine that made its delivery possible. ✈️ TheAeroGraphyOfficial — aviation engineering, WW2 technology, and military innovation explained.
