ELI5: Explain Like I'm 5

Pratt & Whitney J58

The Pratt & Whitney J58 is a very big and powerful engine that is used to make very fast planes called supersonic jets.

To make a plane go very fast, it needs a lot of power, and that's what the J58 provides. It can generate a lot of thrust, which is like a big push that makes the plane go forward.

The J58 is special because it can work at very high altitudes and speeds. It has something called afterburners, which are like super-powerful boosters that can give the engine extra power.

The J58 is used in the SR-71 Blackbird, which is a super-fast plane that used to be used for secret spy missions. The plane could fly at almost three times the speed of sound, which is faster than a bullet!

So the Pratt & Whitney J58 is a super-powerful engine that helps make supersonic planes fly really fast, and it's used in cool and secret spy planes like the SR-71 Blackbird.
