It's just speculation that it will be a bigger Type 15 with some new tech tacked on it. To me, that does seem as a good route, as the Type 15 has amazing specs in its role.Wasn't there also rumours they are moving to a bustle loader based on the one in the ZTQ-15?
Other speculation says it will be unmanned turret like Armata. Which could also be good, because the new type tank will almost certainly be available in large numbers, unlike Armata.
There's nothing wrong with tanks similar to the Leopard 2. It's just that Germany doesn't have the best industrial capacity. China also produces high hundreds to thousands of similar vehicles, despite armored conflict not being the top priority. Would it be China that had to build Leopard 2s, they could make enough 2A6+s to fill the force too. And if Germany had the 99As, they would still struggle with building enough.There are several heavy armor brigades with ZTZ-99 in the northern theater countering K2.
Just look at all these destroyed Ukrainian Leopard 2, is it necessary for all these fancy designs to exist? Air superiority is way more important than comparing ZTZ-99 and K2.
And if it becomes a total war, then tanks are consumables. Tanks like Leopard 2 or K2 are too fancy and expensive, they are not practical at all when it comes to mass production. I perfer 10 brigades of ZTZ-96/ZBD-08/ZTL-11 than one brigade of Leopard 2 or K2.
99As are still early 90s design, despite having APS nowadays. In terms of generation, they are roughly comparable, but the K2 can incorporate more recent tech due to its newer status.By the way, I don't see how revolutionary the K2 is compared to ZTZ-99.
Overall, the 99A will fail out in the long term due to lack of planned upgrades. But presumably the new force using Type 15s and new heavy tanks will completely replace them, with a new ground combat system that is purpose built for network warfare.
