Germany wants Switzerland to sell some of the tanks back to arms maker Rheinmetall (RHMG.DE), which would allow the company to backfill gaps in the armaments of European Union and NATO members.
Germany, Poland, Portugal, Finland and Sweden are among countries sending Leopard tanks to help Ukraine defend itself against Russian attack, creating gaps in their own arsenals.
German Defence Minister Boris Pistorius and Economics Minister Robert Habeck informed Swiss Defence Minister Viola Amherd about the project in a letter dated Feb. 23, the defence ministries in Bern and Berlin told Reuters on Friday.
Under its neutrality laws and a separate arms embargo, Switzerland is prohibited from sending weapons directly to Ukraine.
The Swiss military currently has 134 Leopard 2 tanks in service and a further 96 in storage.
