As Iran and Israel slide ever more into direct conflict, people may wonder what are the most powerful air forces in the region party to the conflict. Iran’s militant group proxies, Hezbollah, Hamas, and the Houthis of Yemen, don’t operate air forces (while the obsolete Syrian Air Force doesn’t dare challenge the Israeli Air Force). There are also powerful players outside the region engaged in the conflict to varying degrees (including the US, UK, and Russia).
