From same guy, a shopping list for Poland:
In short:
- 180 K2, to be upgraded later to K2PL.
- 820 K2PL produced partially in Poland.
- K3PL development project between Poland and South Korea.
- 1,000-1,400 Borsuk light IFV (amphibious).
- Unknown number of heavier AS21 IFVs.
- 144 AHS Krab.
- 48 K9 upgraded to K9PL.
- 642 K9PL based on K9A2.
- Co-development of next generation SPH.
- Poland interested (i.e no concrete plan/buy) in K239 Chunmoo to supplement existing M142 HIMARS and WR-40 Langusta buys.
- 48 F/A-50PL.
- Poland interested in KF-21.
All of these sound very much plausible, except for a potential KF-21 buy. What sounds more reasonable to me is Polish insistence on participation in the KF-21 project as a supplier.
@koxinga I only now saw your question re: Poland and SK cooperating on K2PL. I do not think it will be anything similar to Altay.
Turkey bought the hull design of the K2, but essentially made their own MBT within that mechanical frame.
Turkey's approach was more like "sell us the first building blocks and we'll take it from there".
Poland's approach is more "we want this and that in an MBT, so if you build it like that, and involve us in the production, we'll buy that from you. And the next major upgrade should have our requirements built in from the start, and we'll buy that as well when it's ready".
