"The Versuchstr\u00E4ger 1-2 (abbreviated: VT, meaning \"test-beds\" or \"experiment carrier\") were two German prototype twin gun turretless main battle tanks. Since the early 1970s a number of West German companies have been working on conceptual designs for a successor to the Leopard 1. This project had the name Kampfpanzer 3 (KPz 3). The KPz 3 project was temporarily a British-German joint project, until the UK withdrew because they wanted a turreted tank."@en . . "3.54"^^ . "Versuchstr\u00E4ger 1-2"@en . "9.06"^^ . .
