F119 & F135 in terms of thrust to weight ratio. Allegedly from recent revelation due to DOGE department probe, F119 thrust to weight ratio is 7 at the weight of 2.27 ton, while F135 is 6.7 at weight of 2.9 ton (exclude vertical lift fan). WS15 thrust to weight ratio is at 10.87 at weight of 1.6 ton.Which means F-35A get 19.4 ton thrust using a single 2.9 ton F135 engine, while J-20A get 34.8 ton thrust using 2 x 1.6 = 3.2 ton WS15 engines. F-22 get 32 ton thrust using 2 x 2.27 = 4.54 ton F119 engines. Back then they said J-20 is a bomber when it first reveal.
J-36 using 3 x 1.6 = 4.8 ton WS15 engines get 52 ton thrust, while aircraft that use 2 x 2.9 = 5.8 ton F135 engines get 38.8 ton thrust. Now they still say J-36 is a bomber.
The latest revelation of F-119 engine weight at 5,000 lb.
The latest revelation of F-135 engine weight at 6,422 lb for CTOLCV version, and 7,620 lb for STOVL version.
In light of recent revelation, F-119 spec, specifically the engine weight and thrust to weight ratio have been updated in Wiki.
An engine with thrust to weight ratio 10-11. The only known engine designed with this spec in mind is WS15.
Some said the revelation is actually from a technical doc leaked a year ago.
