On 25 October 1979 the first series-built Leopard 2 tank was handed over to the German army. Since then the tank has gone through several Kampfwertsteigerungen, combat value enhancements. Each version carries its own designation, such as A5 or A7V. From 2019, 104 tanks were upgraded to the A7V standard. The next version is called A8, and its delivery was planned for 2025 to 2026.
