How does the F-35 Lightning II's Pratt & Whitney engine compare to other fighter jet engines?

The F-35 Lightning II is a fifth-generation fighter jet that is designed to perform multiple roles and missions. The F-35 Lightning II is powered by the Pratt & Whitney F135 engine. The Pratt & Whitney F135 engine is a two-spool, axial-flow, afterburning turbofan engine that provides the F-35 Lightning II with supersonic speed and high-altitude performance. The F135 engine has a unique three-stream fan design that allows for more airflow and thrust, while also improving fuel efficiency.

Compared to other fighter jet engines, the Pratt & Whitney F135 engine on the F-35 Lightning II is considered to be one of the most advanced and powerful engines in the world. The F135 engine has a thrust-to-weight ratio that is greater than one, which means that the engine can produce more thrust than the weight of the aircraft. This allows the F-35 Lightning II to accelerate faster and maneuver more effectively than other fighter jets. Additionally, the F135 engine has a longer lifespan and requires less maintenance than other fighter jet engines, which reduces operating costs and increases readiness.
