To the rescue!

 


Yes, ERAWA-2 casettes are covered by 4mm special absorber layer (1K2KS and 1KF2KS absorber) whit mass 6kg/m2 and able to protect against radar working in band X and Ku whit f=8-16GHz. On typical PT-91 sucht absorber cover circa 20m2 and achive reduce detecting range at 50 to 60% for typical conditions.
 


Yes, on Ukarine in 2016 (tests for other client) when ERAWA-2 outperform Knive ERA vs HJ-8, RPG-29 and PG-7VR and BK-14M.  Sorry, no details couse all is classified still :(

Apage satana!

GDLS has ofered Polish Army ca 320 M1A1/M1A2PL  - unfortunatly cost wast to hight for us now. Previously GDLS has ofered ca 800 M1A1PL for ca 4,5 billion Euro. And service center in Poland.
Future of the armoured corps is still old shitty T-72M1. Sad.
 

And control station whit polish president

My friends draw about Spz Puma upper frontal hull armour.
 

 
 
 

Well in SPz Puma even hot air exhaust is made by double slopped NERA:
 

 
 

 
 

 
 
About month ago I looked very cearfully on Shutzpanzer Puma on Ostrava NATO days :-) Lets's sey that is  better protected then I suspected. Mucht better. Talks whit crew was very interesting too.
 
In fact for upper front hull part SC jet or 30-40mm KE rod must overcome 2 or 3 slopped on 18@ NERA plates, then overcome slopped front plate (LOS ca.50-60mm) then fly trought engine comparment and finnaly overcome 20mm bulkhead before crew comparment.  In lower hull we have two slopped 15mm plates whit primary engine fuel tank (50L) then we have huge slab of metal - HSWL and MTU engine and then 20mm bulkhead.
IMHO Puma front is between 200-250mm vs KE penetrator from medium caliber automatic canons. In case SC warhed lower hull is less protected but upper hull - it shoud be able to stop any 80's ATGM without precursor and propably RPG-28 and PzF-3T frontally. A lot of NERA and huge space is nice protection IMHO.    
Couple photos:
Engine compartment - look at triple NERA layers:
 

 
NeRa or NxRA everywhere...:

 
Here is visible bulkhead thickenss:

 
And chamber for 50L fuel tank and doubla slopped ca.15mm plates:

 

In some way funny but it's seems that Abrams are seriously consider for polish army...
 
11 Armoured Cav. Div. HQ told to brigades that in December will be finall decision about take ca.240 M1 Abrams. I'sholud be sceptic but source is rather good.
Abrams should be taken by two brigades: 10Armoured Cav Brig and 34 Armoured Cav Bde. Still Im doubt but knowing this goverment - it's possible...
 

Here is a German news article about the MGCS and possible European partners (it is mostly talking about Poland, but uses it as example for problems that can be found with most of Eastern Europe):
 
https://www.faz.net/aktuell/politik/ausland/ruesten-fuer-europa-huerden-fuer-den-gemeinsamen-kampfpanzer-16439321.html
 
Interesting parts:
Poland backed an Italian alternative program to the MGCS, which then was apparently canceled - France has not forgotten that and thus doesn't like Poland as partner for the MGCS Industrial capabilities of Eastern European countries are limited and often focused on upgrading old Soviet vehicles. Due to the fact that industry is often inter-woven with politics, they are considered unreliable (illustrated by Poland canceling a contract buyiing French helicopters in 2016 just because some politicans wanted to appease their American partners) big holding companies like PGZ are deemed to be bad for innovation, making Poland a less attractive partner, as they lack competition while being state-owned/state-driven

And and that this info's came public due to sevral polish military journalist in 2015 ;-)
 
More seriously - sucht german patent:

Show this idea:

 
 
When we are talking sevral years ago the only posiblities to overcome sucht thick and multi-ERA-layerd armour like on Oplot-M (whit some consist Lmax for western 120mm ammo) was to change idea of the attack, and infos about data-link for M829E4, Nexter OLF-F1NG, and...KE2020 whare some aditional help to think how to hell it could work.
And really the only resonable option is detached during fly precursor -in fact it can be very elegeant and simply solution but onnly whit state-of-art metalurgy. Just metal  conection beetween main rod and precursor which overheat during fly  lets go "precursor" - rest is pure areodynamic or in more complex way - small air breakers somwhere near fins or tracer - just tiny ones to very small incarase aerodynamic resistance.

Well in SPz Puma even hot air exhaust is made by double slopped NERA:
 

 
 

 
 

 
 
About month ago I looked very cearfully on Shutzpanzer Puma on Ostrava NATO days :-) Lets's sey that is  better protected then I suspected. Mucht better. Talks whit crew was very interesting too.
 
In fact for upper front hull part SC jet or 30-40mm KE rod must overcome 2 or 3 slopped on 18@ NERA plates, then overcome slopped front plate (LOS ca.50-60mm) then fly trought engine comparment and finnaly overcome 20mm bulkhead before crew comparment.  In lower hull we have two slopped 15mm plates whit primary engine fuel tank (50L) then we have huge slab of metal - HSWL and MTU engine and then 20mm bulkhead.
IMHO Puma front is between 200-250mm vs KE penetrator from medium caliber automatic canons. In case SC warhed lower hull is less protected but upper hull - it shoud be able to stop any 80's ATGM without precursor and propably RPG-28 and PzF-3T frontally.

My anotherone  article - this time:
 

 
 
RAK  SELF - PROPELLED MORTAR vs COMPETITION
Article in english:

RAK  vs Nona, Vena, Chosta, AMOS, NEMO, Mjolner.
 
 

But there's one problem.
 
Elbit's UT30MK2 hasn't passed climatic tests for Romanian army. Its FCS is going crazy in low temperature so this problem concerns also a MT30MK2 offered for Czechia.      

From my article about 2AV armour.
 
Many thanks for all peoples who help me whit this subject ;-)
