So the British are modernising the Challenger. The Challenger 3 will have a 120mm smoothbore(finally) so it seems they have finally given up on that rifles nonsense. But it won't have a 130mm though I kind of thought that it would not. They are going to have 148 of them, certainly the numbers are getting low. Australia has 50.
I don't know. They say that it has fancy technological systems integrations but is it really that much of a step up? It has a gun that everybody else has been using for a while now and it is an updated version of a reasonably old platform yet they say this is future proof. It will be coming into service in 2030. 2030! By then we might be seeing autoloading 130mm tanks rolling about(the ones that India and Brazil build as they are going to be superpowers by then, surely).
