The Netherlands and Denmark are set to deliver 14 refurbished Leopard 2 tanks to Ukraine, the Dutch defence ministry has said.
Both countries in April last year said they would buy the tanks from a third party and get them ready for battle in Ukraine.
The tanks have been completely brought to battlefield standard by by German arms manufacturer Rheinmetall after months of testing.
They will be delivered before the end of summer, the ministry said.
"The Leopard 2A4 tanks can help Ukraine gain the upper hand on the battlefield," it said in a statement.
