T turbojet engines are limited to what weight class of aircraft?

Turbojet engines are capable of powering a wide range of aircraft, from small light jets to large commercial airliners and military fighters. This makes them versatile and suitable for all weight classes. Turbojets are designed for high-speed performance and efficiency at high altitudes, attributes that are beneficial across different aircraft sizes.

While lighter aircraft typically use turbofan engines due to better fuel efficiency and noise reduction characteristics, turbojets can still be found in many types of aircraft, including small, medium, and heavy classes, particularly in military applications and older commercial jets. Thus, the correct understanding is that turbojet engines are not limited to any specific weight class and can power aircraft of all sizes.
