Well it's seems that all polish 2A4 will be improved to level
over the leopard-2A5, in fact polish "maximum" variant is preatty close to the Leopard-2A7.
Modernization of the single Leopard-2A4 to 2APL level is assumed by polish MoD on between 2-2,5milion euro.
in
the required basic level modernization consist:
"basic level":
1. replacement PERI R17 whit new PERI R17A3 whit Attica thermal camera
2. full hunter-killer plus mode between Tk and Tc
3. new driver night vision block and new rear driver camera from polish PCO factory: KDN-1
4. replacement main turret "special armour" (inside armour cavity) by newest avaible ones (yes yes yes!)
5. elimination EMES-15 gap by rising whole EMES-15 vision block above turret roof, remove new PERI, total change gun mantled mask whit new placment FERO
6. spall-linear inside turret
7. ready to use "fixing point" do aditional special armour (NERA?) in front of the turret and hull
8. changes in FCS to use air-burst 120mm ammo (polish production ones or from other manufacures)
9. replacment turret elevation and stabilisation mehanism to fully electrical - so from WNA-H22 to E-WNA
10. new interface and the workplace for Tank Comander, and for Gunner
11. use CAN to keep all system and new RPP-1 system
this above is "basic level" -the minimum needed by polish MoD, but they are some additional modernisation levels: A, B,C,D - it's possible modernisation level beyond basic level. propably polish MoD will decide to modernisation in sucht way - to achive circa leopard-2A7 level. Levels (A B C D) are listed according to the priorities of the polish MoD -so A level will be done first - level D only when extra money will be avaible. Propably if offered price in this trade will be good for polish MoD level basic + D (maximum program) will be implemented.
levels:
eacht level consist minimum "basic level" + some addons in few groups (A,B.C.D)
level A:
basic level + external aditional modular armour on turret front and hull front to incarese protection in +/-35. degree from longitiudal axis, APU whit it's separate STOPFire sytsem, new drivers anti-blast seats
level B:

level C:
basic level + level A + level B + replacment EMES-15 thermal camera by next Attica - so more or less changing whole EMES-15. Cooling system for crew and electronics block.
level D:
