Poland's National Security Bureau estimates construction of a permanent US military base, proposed as 'Fort Trump,' could cost up to $4.4 billion. The base would host about 5,000 American troops and could open in 2029. No final US decision or site selection has been made.

Key Facts

Poland's National Security Bureau estimates the base could cost between 11 billion and 17 billion zlotys, up to $4.4 billion.
The base is planned to host about 5,000 American troops.
Under favorable conditions, the base could open in 2029, while Deputy Defense Minister Stanislaw Wzientek said full readiness may come after 2030.
The Polish government tasked negotiations on June 16 to agree on location, infrastructure, costs, and funding sources with the US.
The name 'Fort Trump' was first proposed in 2018 by then-President Andrzej Duda and has not been approved.

Cost Estimates

Poland's National Security Bureau provided written responses estimating the base construction at 11–17 billion zlotys, up to $4.4 billion. The estimate assumes about 5,000 American troops stationed at the facility. The bureau said the multi-year expenditure would not exceed the Polish defense ministry's budget capacity. It described the project as comparable to building a small town, including infrastructure for troops, families, and base personnel.

Site Selection and Timeline

No site has been chosen, with requirements including proximity to an airport, highways, a logistics hub, and a major city in western Poland. Areas near Wroclaw are considered for a heavy ground brigade, Poznan for an aviation component, and Szczecin remains an option. The base could open in 2029 under favorable conditions, but Deputy Defense Minister Stanislaw Wzientek said full readiness may be reached after 2030. The US has not made a final decision and will first determine its force posture in Europe, with a review expected by the end of 2026.

Negotiations and Naming

The Polish government tasked negotiations on June 16 to agree on location, infrastructure, costs, and funding sources with the US. Defense Minister Wladyslaw Kosiniak-Kamysz said the US responded positively to Warsaw's proposal. The name 'Fort Trump' was first proposed in 2018 by then-President Andrzej Duda and has not been approved. President Karol Nawrocki said the base would be named after the US president if both governments complete the project.
