In terms of machine vs machine comparison, AH1Z is miles ahead of Z10 in every aspect, better payload, better cruise, better survivability, better situation awareness, better maintenance, a more modular design and higher availability rate than which increases its 'fear factor' in comparison with that of Z10.
Only aspects which benefit Z10 are that it's cheaper, can be fielded in large numbers and carry no risks associated with supply chain blockade.
AH1Z were (are) suppose to deploy in Multan, a critically vulnerable spot where the threat of Indian armor offense is maximum.
It can sustain adverse weather conditions and will remain available at its optimum capacity for longer duration of time in the conflict. This is something Z10 cannot do (or was not able to do). Last time it's electronics burnt up in extreme heat and engine showed indications of power loss in certain conditions while carrying 'maximum payload'.
Now how Z10ME will rectify such issues is not in my knowledge. Yes, quantity can generate its own quality as may be 36 Z10ME can be deployed instead of 12 AH1Z. But again, the adversary will be fielding AH-64E equipped with longbow/hell fire combination which will give it such qualitative advantage which cannot be overcome by fielding more Z10 helicopters. We need a 'quality' solution also. One which could put mmW FCR and 16 ATGM capacity on table.
Pal I don't deal with such paper comparison. Pakistan has evaluated both T129 & Z10 to their maximum capacity. Their results show which one is better.
