lol just a slight over-estimate there, maybe around 40 would be a better number
in recent times around 6-7 of our AH-1 Cobras have been so badly damaged in COIN operations they have been taken out of service and cannibalized for spares parts, it would be interesting to see how well this helo stands up to battle damage and how well it takes a punch
That's a good question, and I hold some reservations about just how suitable the Z10 might be for a country like Pakistan who would likely by using their attack helos against a low-tech adversary.
Looking at the sleek lines of the Z10, it's construction (the fuselage is a single piece composite structure) and the comprehensive array of sensors and countermeasures installed, and you can see that the Z10 was designed to fight a high-tech enemy, and would be relying on it's stealth, agility, sensors and countermeasures to survive combat rather than thick armor.
The Z10 was designed to pick apart hostile heavy armored formations from a distance and with massive friendly ground and air support. It was primarily designed to evade missiles rather than withstand AAA fire. The Z10 seems more like a fencer rather than a street brawler.
As such, it looses much of it's greatest strengths if pitched against an enemy who does not have heavy armor for the Z10 to target or rely on fancy missiles that the Z10's self-defense suit is optimized to spoof.
The best MAWS will not help you when some guy is aiming a HMG or RPG at you with iron sights, and neither will ECM or chaff/flairs/laser dazzlers cause a bullet or RPG round to deflect from it's target.
If Pakistan wants Z10s as a counter against India, I think it would be a perfect fit, but I hold reservations about just how effective the Z10 would be if pitched against insurgents.
I think the world's attack helos can be divided into roughly two groups. You have your high tech 'fencer' helos like the Tiger, Ka50/52, Z10, and then you have your beefy 'brawler' helos like the Apache and Mi28.
Against a high tech foe, your 'fencers' should fair better because they have a better chance of avoiding being hit, and with high tech foes, if you get hit by a big-ass missile, slightly heavier plating and sturdier design won't help much. OTOH, against low tech foes, the 'brawlers' do better because their slightly heavier armor and sturdier construction often makes all the difference when your first warning of being under attack could be the sound of enemy fire smashing into your hull.
I think that there is a reason the Russians decided to buy the Mi28 as well as the Ka50/52 and why the US operates both the AH64 and the AH1.
China does not really see itself ever having to fight a COIN war, and even if it does, it has the manpower to flood the area with friendly boots and that is ultimately the only fool-proof solution to an armed insurgency. Because of this, the Z10 was designed primarily to fight other high-tech armies. It's just a matter of slightly different operational requirements and design goals between what the PLA wants and what the PA might want in an attack helo.
If Pakistan wants an attack helo mainly for COIN, I think it can do a lot worse than taking a long hard look at the Mi28, especially if they are only looking at a modest order.
If Pakistan wants a massive number of attack helos, it might be better to follow the JF17 model and team up with China to design a new one from the ground up to specifically meet Pakistan's unique needs.
