Russia has bases in São Tomé and Príncipe.

Since the beginning of the war in Ukraine, Russian ships and submarines have passed along the Portuguese coast, only leaving with the intervention of our navy and even before this war, it was customary for Russian jets to violate the airspace of a random European country at least once a month, only leaving under the escort of the air forces to test their response time. We are not that protected from Russia as the geographical distance might erroneously lead us to believe.

In short, jets are needed for at least surveillance, deterrence and joint missions with our allies.

P.S.: I hope it doesn’t happen, but Trump has already threatened to violate the territorial integrity of Canada and Denmark. Who can guarantee that he won’t do the same to Portugal? The Azores archipelago, halfway between the US and Europe, is quite important strategically. He might consider claiming our islands.

I’m sorry but you’re just talking of your ass there.

Portuguese Air-force assets, including fighter jets, are constantly deployed to the Portuguese Economic Area for missions such following the naval assets of hostile nations passing through or near it or even investigating possible criminal activity. The maritime EEA of Portugal is way larger than the actual country and at times the only vehicles that can reach further out enough fast enough are fighter jets.

Furter, fighter jets are literally the only kind of significant help Portugal would be able to send within to its Eastern European partners in the EU and NATO if Russia invaded them (certainly neither the Leopard tanks or regular infantry would get there for a while).

By pointing out that the land territory of Portugal is at low risk of invasion you’re actually making the point in favor of fighter jets since those assets make a lot more sense than ground-based assets for a country whose main military demands are on a huge sea area off its territority including far-away parts (around Madeira and Azores) and its military obligations in the two large military alliances the country is part of.
