This is just standard procedure ever since the Baltic states joined NATO. Those countries don't have any airforce, so the other NATO countries take turns, every 6 months I think, stationing some planes in one of the countries or in northern Poland.
This is discussed in one of my books, "Vlad" (2021), which describes a fictitious Russian operation to close "The Suwałki Gap" by annexing a strip of southern Lithuania, joining Kaliningrad to Belarus.
Ämari Air Base here in Estonia always has allied fighters ready to deploy, NATO Baltic Air Policing is essential in the East Flank. They've been busy recently. Also had a drone crash 15 from my location recently due to russian EW.
Greetings from Estonia.
That's not how NATO air policing works though 😅 It's not Turkish fighters doing as they please in their own sovereign national airspace, it's strictly controlled and following NATO parameters in Estonia airspace— there'll be no shoot down unless russian fighter / bomber engages first.
Turkey is the only NATO force that has shot down a Russian Fighter jet, an Su24 in 2015. We know Erdogan self-serves, but Turkey doesn’t fuck around when defending its territory and Russia won’t prod them again.
Or to convince Estonia to buy Turkish armour again, after switching away from Otokar and Nural Makina. Regardless, NATO air policing is what matters here, and we won't be buying anything we don't want or need.
Baltic air defense is served by NATO allies on a rotational basis (the Baltic states don't have their own fighter jets). It was Turkey's turn to send some planes. It's a routine deployment, I don't think there's reason to believe they expect something specific in return.
