In 2012, India barred Zurich-based Rheinmetall Air Defence from arms deals in connection with corruption allegations. Investigators accused an Indian intermediary of receiving US$530 000 to secure the company’s removal from a blacklist. Rheinmetall denied the allegations. In 2014, Federal Councillor Ueli Maurer lobbied his Indian counterpart in support of a suspended order for the Indian navy. In June 2026, it was reported that the Zurich subsidiary’s exclusion had been extended until 2028. Fire-control systems were exported to India in 2017 and 2018 through Tethys Systems, founded by former Rheinmetall managers. WOZ reconstructed the transactions by cross-checking licensing and export data; in 2017, the approved value was 8.3 million Swiss francs. Tethys held a Rheinmetall licence. On 26 April 2017, the competent Indian criminal court discharged Rheinmetall Air Defence, Gerhard Hoy, Abhishek Verma and Anca Neacsu from the bribery proceedings. The CBI challenged the decision in the Delhi High Court that same year. The Central Information Commission’s information-access decision of 11 May 2026 documents the separate administrative procurement ban and its extension in 2023. The Rüstungsreport profile lists approved Tethys export values of 75.05 million Swiss francs (2015), 14.42 million (2016), 8.31 million (2017) and 2.29 million (2018), all for fire-control equipment.
