Executive Summary

The Swiss Army will remain defenseless against air attacks until at least 2030. The Defense Department (VBS) is struggling with massive delays and cost overruns in critical major projects such as Air2030, the airspace surveillance system Leis, and the F-35 fighter jets. At the same time, there is a lack of political and financial confidence: 62 percent of the population doubt efficient use of funds, 76 percent reject the planned VAT increase.

The VBS is under pressure: Three of four Air2030 subprojects are off schedule. The new airspace surveillance system Leis is delayed until 2030 – originally planned for 2024 – and costs twice as much as budgeted. The F-35 fighter jets are becoming more expensive than expected, the Patriot air defense system is suffering from unclear US delivery timelines. Critical: By 2028, Switzerland has no financial means for necessary down payments, while European intelligence agencies warn of Russian test scenarios from 2028 onwards.

Detailed Summary

Systematic project problems dominate the VBS. The Airspace Surveillance and Operations Control System (Leis) fails due to integration into the Army's new digitalization platform – which did not exist when the project was supposed to start in 2024. The VBS needs approximately twelve additional positions and has now engaged Thales, the French defense contractor, for external support. The costs are unclear but should remain within the 300 million franc framework. In parallel, a fundamental pattern emerges: complex major projects are systematically underestimated, while old weapons systems deteriorate – the M113 armored personnel carriers had to be taken offline again.

Financing crisis exacerbates security gaps. The Federal Council proposes a temporary VAT increase of 0.8 percentage points for ten years to mobilize 31 billion francs for capability gaps. However: Only the Center party openly supports the measure, 76 percent of the population rejects it. Armaments Chief Loher made clear that weapons systems have become 40 percent more expensive, delivery times are six years, and down payments of approximately one-third of the purchase price are mandatory.

Dependence instead of sovereignty. Switzerland has no own sensors outside its territory and depends on air situation data from neighboring countries. In return, Bern can offer nothing – military information about Swiss airspace is excluded. This dependence contradicts demands from partner countries, who expect that Switzerland can "at least defend itself."

Key Statements

  • Critical vulnerability: Switzerland cannot take action against air attacks until at least 2030; precisely in the time window when European states expect intensified threats.
  • Financing debacle: 62% of the population doubts efficient use of funds; political majority for tax increase is lacking; without new financing, down payments are also impossible by 2028.
  • Systematic project deficiencies: Leis costs twice as much, integration problems were underestimated; F-35 and Patriot suffer from price jumps and delivery delays; M113 fleet shows aging problems.
  • Geopolitical time window: Russia could test European defense readiness from 2028 onwards; Switzerland must order today to be equipped by 2028 – impossible without financing.

Critical Questions

  1. Data Quality: What objective metrics show that the VAT increase is the right financing mechanism – and not just symptom management for management failure at the VBS?

  2. Conflicts of Interest: To what extent do defense contractors (Thales, US manufacturers) influence VBS cost forecasts and schedules, and are there external audits to validate them?

  3. Causality: Are the Leis delays really only due to subsequent digitalization platform integration, or are fundamental project management standards lacking at the VBS?

  4. Feasibility: How realistic is it that the Federal Council will obtain air situation data from neighboring countries under the demanded exchange veto – and what actual military capability results without this data?

  5. Side Effects: If the VAT increase fails, does the VBS have concrete emergency scenarios for air defense 2028–2030 or will Switzerland be effectively defenseless?

  6. Counter-Hypotheses: Could a reduced air defense ambition (only hybrid scenarios) be more cost-efficient in the long term than the current stop-and-go projects?
