Executive Summary

armasuisse is remediating the military shooting range Langnau near Reiden in the Canton of Lucerne on behalf of the Swiss Army. The project includes noise protection measures, remediation of contaminated sites, and renaturalization of the Weierbach stream. Construction work is scheduled for summer 2027 to spring 2028 and will cost approximately 3.2 million Swiss francs. The goal is full compliance with noise limit values in the surrounding area.

Detailed Summary

The Langnau military shooting range near Reiden has been used by various units of the Swiss Army for approximately 60 years. The range operates year-round for up to 35 weeks and is used for combat shooting as well as occasional explosive exercises.

The planned remediation pursues several objectives: reduction of shooting noise exposure in the surrounding area through relocation and new construction of infrastructure, elimination of soil contamination, and ecological enhancement. Although noise limit values are largely complied with today, the measures are intended to guarantee them comprehensively.

Concrete measures:

  • Short-distance shooting stations (KD-boxes) will be relocated downhill
  • New KD-box 3 with emission-free bullet traps at the new location
  • Opening of the Weierbach stream over 120 meters in length
  • Creation of a pond for ecological enhancement
  • Removal and proper remediation of contaminated soils at all shooting station locations

The public inquiry of the military planning approval procedure is scheduled for spring 2026. Implementation begins in summer 2027 and ends in spring 2028.


Key Statements

  • Noise protection in focus: Infrastructure will be strategically relocated to permanently reduce noise exposure
  • Environmental justice: Combination of remediation, elimination of contaminated sites, and stream renaturalization
  • Costs: Approximately 3.2 million Swiss francs for the entire project
  • Timeline: Planning phase 2026, implementation 2027–2028
  • Participation: The public was informed on 26 January 2026 and had the opportunity to ask questions
