Overview
- Government now expects total costs of around €2 billion, up from the initial €700 million estimate in 2023.
- Officials attribute the overrun to compressed construction timelines and U.S. security mandates that restrict the pool of cleared contractors.
- The project remains on track to deliver new runways, hangars and a high-tech center supporting 35 F-35 jets by the 2027 deployment deadline.
- The upgrade is the Bundeswehr’s largest and most complex construction effort, driven by NATO nuclear sharing obligations.
- The Büchel renovation sits alongside a broader €67 billion Bundeswehr infrastructure backlog and has prompted plans for a new law to expedite military construction approvals.
