A Russian Mi-8 military helicopter briefly crossed into Polish airspace north of Braniewo on Sept. 22, according to the Polish Army Operational Command, in an incident that has intensified debate over NATO’s eastern defenses.
The helicopter, which entered from Russia’s Kaliningrad region, crossed into Polish territory at 11:08 a.m., reaching a maximum depth of about 300 meters before leaving 42 seconds later. Polish radar tracked the aircraft throughout, prompting fighter jets to scramble and ground-based air defense units to go on standby.
Polish military authorities said the brief incursion showed Moscow was testing the readiness and response times of NATO air defenses.
The incident happened within hours of remarks in New York by Polish President Karol Nawrocki, who revived a proposal to build a permanent U.S. military base in Poland known as “Fort Trump.” Foreign Minister Radosław Sikorski also raised the Braniewo incursion during a briefing with Polish media following his address to the U.N. Security Council.
Background on the base push
The “Fort Trump” idea dates to 2018, when Nawrocki’s predecessor, President Andrzej Duda, first suggested naming a permanent U.S. installation in Poland after Trump as part of an effort to secure a lasting American military presence.
Nawrocki said he was confident Warsaw and Washington would finalize a deal, though he acknowledged no specific timeline has been set because administrative and financial details remain unresolved.
“I hope that when work on the base is completed, President Trump will be able to personally attend the inauguration of ‘Fort Trump,'” Nawrocki said in New York on Sept. 22.
“It’s hard for me to give specific dates, but I think this matter has been definitively confirmed, because President Trump is known for keeping his word,” Nawrocki told Bloomberg. “Infrastructure preparation is progressing. In fact, the appropriate infrastructure is already being selected.”
Nawrocki called establishment of the base “only a matter of time” and said he was optimistic construction could be finished before Trump’s term ends in 2029.
Deputy Defense Minister Stanisław Wziątek said the base’s exact location has not been settled but that it would likely host between 3,000 and 5,000 U.S. troops. Poland ultimately wants to host around 15,000 American troops, building on the roughly 10,000 currently stationed there, largely on a rotational basis.
Wider tensions
Polish Prime Minister Donald Tusk warned on Sept. 18 that, according to intelligence available to Warsaw, Russia was planning drone and missile strikes against eastern NATO countries that Moscow could try to pass off as accidental, The Associated Press reported.
Russian drones have repeatedly entered NATO airspace and crashed on alliance territory, including in Poland and Romania, prompting NATO members to scramble fighter aircraft in response to Russian aerial activity near their borders.
President Trump has signaled support for the base project, calling it a “historic step for our Great US/Polish Alliance” in a Truth Social post on Sept. 17: “Thanks to the bold leadership of my friend, Karol Nawrocki, President of Poland, major progress is being made towards establishing a US Army base in Poland.”
