All modern fighters have turbofan enginesBasically that. And yes Turbo jet enineSlovenia doesn't have fighter jets. At best they have a Dassault Falcon 2000EX, which is a business jet converted to medical transport. The rest is prop driven.Do you nerds see/hear military jets that rarely?Umm...
Where do you live that you've never heard a jet engine before?
Perhaps you are referring to military aircraft, since jet engines are on commercial airliners.
Here in swiss you can see them regularly, but then its a small country so oh well.
And even here in Germany hearing fighter jets is rare. Which has a lot to do with a low level flying ban (thanks Ramstein) and most bases being far from cities.
The only time I heard fighter jets growing up was when we still had MiG-29s and they were upgraded in my hometown not 500m from my parents' place. They ended up doing test laps over the city (one wing commander explicitly did that over schools).
