The Hellenic Air Force is one of the most powerful in Europe. With 37 helicopters, 343 fixed-wing aircraft including 206 fighter jets, as well as surveillance drones and surface-to-air missile systems in its service, it plays a key role in protecting Greece and its allies in the Mediterranean. In recent years, Greece's fleet of combat aircraft, particularly fighter jets, has been upgraded to ensure the force retains its position within NATO's structure. Alongside combat aircraft, the Hellenic Air Force has a significant domestic role that requires a fleet of water bombers to protect the country and its infrastructure from forest fires. Alongside are helicopters fulfilling search and rescue missions and training aircraft to ensure continuity of service throughout all the Air Force's specialist branches.
