Rheinmetall wants to provide Ukraine with the KF51 Panther. Expect many more Russian tankers in orbit.
I feel that's a rather cruel marketing stunt on Rheinmetall's part. They should know that KF51 is many years away from service. At the moment, it's a concept vehicle. Actually, a concept
turret on a dressed-up Leopard 2 hull. And AIUI Rheinmetall has neither the license (KMW's design) nor the means to build new hulls.
The better move to support Ukraine (and NATO) would be to drastically expand Leo 2A7 production capacities. With proper funding, I'm sure the industry will gladly open another production line, even if it's just for a limited number of years/vehicles.
