Announcement of Progress
On September 17, 2026, President Donald Trump posted on Truth Social that “major progress” is being made toward establishing a U.S. Army base in Poland and that the location would be announced “very soon.” He framed the development as a historic step for the U.S.–Polish alliance and credited Polish President Karol Nawrocki for the advance.
Background & Context
The United States has maintained a rotational presence in Poland since 2017, with roughly 10,000 service members deployed primarily on a temporary basis. Two permanent installations already exist, but both are sized for limited forces. Earlier in 2026 the Pentagon paused a planned deployment of 4,000 troops; President Trump later pledged an additional 5,000 troops, reversing the pause.
Poland allocates about 5 percent of its GDP to defense and has urged a larger, permanent U.S. footprint on NATO’s eastern flank after Russia’s 2022 invasion of Ukraine. Polish officials have offered to share the cost of a new base, aligning with Warsaw’s strategy to strengthen deterrence.
The announcement comes as the Pentagon conducts a Europe-posture review slated for completion in December, a process that could affect force levels abroad.
