The F-35: Even the engine is compromised
By David Archibald

The measure of the efficiency of a jet engine is its Thrust Specific Fuel Consumption or TSFC for short. This is its fuel consumption per unit of thrust and for US jet engines is measured in lbs per hour per pound of thrust. The TSFC of the F100-PW-229 engine that powers the F-15 and F-16 is 0.726 lb/Hr/lb.  The F-15 first flew in 1972. More than 40 years later, the TSFC of the F-135 engine which powers the F-35 is 0.889 lb/Hr/lb. This is 22% higher than the F-15’s fuel consumption despite all the decades of engine development in between.  If the F-35’s engine was as efficient as that of the F-15, the F-35 would be able to fly 22% further on its fuel load.  This is a big deal, so what happened?

You would think that the legacy of failure to design a fighter plane to satisfy ALL the different services needs would have stopped further efforts after the F-111, but no, our ever cost conscious federal bureaucracy keeps on trying the same old thing over and over with the same results.
