If it is Japanese, don’t be surprised if it has leapfrogged the king of skies, the US F22 which has decades old technology.
It’s not going to leap frog much of anything if it really has engines with 5000kg of thrust
“It’s not going to leap frog much of anything if it really has engines with 5000kg of thrust”
The raptor engines have about 35000 foot lbs of thrust.
If the number 5000 is metric then this is 5000 kilogram meters of thrust or about 5000x2.2 lbs. per kg x3.1 ft per meter or 6.8 times 5000 ft lbs or 34000 foot lbs. of thrust.
Pretty much the same as the f22 raptor.
