Why The P-47 Thunderbolt Threw Away 2,000 Horsepower For Two Years The P-47 Thunderbolt carried the most powerful fighter engine America built during World War II, yet for two full years it climbed like it was underpowered. This video breaks down the real engineering story behind that paradox: Alexander Kartveli's turbo-supercharger obsession, the P-35 and P-43 Lancer that came before the Jug, the 1943 bomber escort crisis and the Schweinfurt raids, Hubert "Hub" Zemke and the 56th Fighter Group's dive-and-extend tactics, and the overlooked mechanical flaw that quietly wasted a huge share of the R-2800 engine's power for two years: the propeller. We trace how a set of thin "toothpick" Curtiss Electric propeller blades limited the P-47's climb rate long after the engine itself had more than enough power to spare, and how the introduction of wide-chord "paddle blade" propellers in the winter of 1943 into 1944, alongside water injection, finally let the Thunderbolt use the power it always had. The story builds to March 6, 1944, the first daylight raid on Berlin, when German pilots discovered their reliable vertical escape tactic no longer worked against the reborn P-47. This is a deep dive into WWII aviation engineering, fighter tactics, and the kind of overlooked mechanical detail that changed the balance of the air war over Europe, alongside the legacy of Alexander Kartveli through the F-84, F-105, and A-10 Thunderbolt II.
