US President Donald Trump publicly rebuked German Chancellor Friedrich Merz after Merz criticized the US approach to the Iran conflict, prompting Trump on Truth Social to say Merz “doesn’t know what he’s talking about.” Trump then threatened to reduce US forces in Germany, and US Defense Secretary Pete Hegseth ordered the withdrawal of about 5,000 American troops over the next six to 12 months. Such threats are not new, but US bases in Germany remain strategically important and economically significant.
Scale and footprint
Some 35,000 to 39,000 US soldiers are stationed in Germany, plus roughly 13,000 Air Force personnel. They occupy about 20 major sites, mainly in the south and southwest, and roughly 40 US-run military installations in total.
Ramstein and Spangdahlem
Ramstein Air Base in Rhineland-Palatinate is the largest US base outside the United States. It is a logistics hub for troops, equipment and freight bound for the Middle East, Africa and Eastern Europe, and supports NATO airspace surveillance. Ramstein hosts satellite relay infrastructure used to control combat drones and serves as a medical hub: injured personnel from operational theaters are flown to Ramstein and treated at nearby Landstuhl Regional Medical Center. Both facilities are part of the Kaiserslautern Military Community, which comprises more than 50,000 US soldiers, civilian employees and family members.
Spangdahlem, about 120 km northwest of Ramstein, is primarily operational. It hosts a fighter squadron—around 20 F-16 aircraft—that acts as a rapid reaction force to help secure NATO’s eastern flank and to suppress enemy air defenses.
Stuttgart and Wiesbaden
Stuttgart houses the US European Command (EUCOM) and US Africa Command (AFRICOM), coordinating US military activity across Europe and Africa. Wiesbaden hosts the headquarters of US Army Europe and Africa and plays a role in coordinating Western arms deliveries and training programs for Ukraine.
Grafenwöhr and Hohenfels
These Bavarian training areas form the Joint Multinational Readiness Center, the US military’s principal training hub in Europe. Grafenwöhr offers large live‑fire ranges and modern training grounds; Hohenfels provides realistic combat scenarios in mock villages, sometimes using civilian role-players. Thousands of NATO troops train there annually to enhance interoperability.
Büchel
Büchel air base in Rhineland‑Palatinate is widely believed to be Germany’s only remaining nuclear weapons site under NATO “nuclear sharing.” While neither the US nor Germany has officially confirmed stockpiles, the Stockholm International Peace Research Institute (SIPRI) estimates 15–20 tactical nuclear bombs may be stored there. Büchel hosts a German tactical air squadron trained for nuclear delivery and a US ammunition support squadron responsible for maintenance and storage support. The base is currently undergoing extensive upgrades.
Why so many bases in Germany?
After World War II the western zones of occupation left substantial US forces concentrated in the south and southwest. During the Cold War West Germany was a frontline state bordering Warsaw Pact countries, and the US built up forces—peaking at over 250,000 troops in the mid-1980s—to deter the Soviet Union. After the Soviet collapse, Germany’s central location remained useful for operations in the Middle East and Africa and for securing NATO’s eastern flank, so bases continued to be used despite a steady reduction in troop numbers.
Economic importance to Germany
US bases are major local economic drivers, especially in rural regions where the US military is often the largest investor and employer. More than 10,000 Germans work directly for US forces; an estimated 70,000 jobs are indirectly tied to contractors and service providers such as construction and retail. The US invests billions annually in base operations, modernization and expansions. Germany‑based US personnel and their families spend in local businesses, and the military community contributes up to about €3.5 billion ($4.1 billion) a year to regional economies.
Conclusion
US military facilities in Germany remain strategically valuable for logistics, command and control, medical support, rapid reaction forces and multinational training, while also supporting NATO nuclear arrangements. They are embedded in local economies and shaped by decades of postwar and Cold War history, which helps explain why debates over troop levels and base presence draw both political attention and public concern.
