The most significant difference between civilian and military engines lies in the design of the afterburner construction.
The former doesn't include an afterburner, its rated output is capped at the threshold of maximum safety and economy, and even flooring the throttle keeps it within rated power.
The latter, for combat purposes, sacrifices lifespan for extra power output, as both training duration and actual combat time are much less than civilian operational hours. Designing for too long a life would lead to excessive costs and also affect the renewal of current equipment; therefore, the best technology is not necessarily the most advanced.
If military engines were to be used with reduced power requirements and operational standards, their fault-free operational lifespan could far exceed their original design parameters.
In some ways, they could also be used as universal engines.
