Can this Tank compare up against the M1A2 Abrams,Leopard M1A2, British challenger and the French Leclerc.(top 4 tanks with chobom armor.)Also what about the Type-99 that i herd off. Which is Better
No, no, no, and no...
Just as the Israelis done a good job in upgrading the M-60 into Sabra standard, the upgraded tank is still not on par with a brand new (latest) M1A2.
But that's not the purpose of the upgrade. Money doesn't grow on trees, and the army is often left with the smallest budget for vehicle procurements. While the AF is given $90 million/plane, the army grunts have to break out the torch and bolt hillbilly armor to their vehicles.
The PLAAF or PLAN is far more likely to receive billions of dollars for new planes or ships, than the PLA for new tanks. If budget wasn't a consideration, I'm sure the PLA would love to procure T-99 MBT's by the thousands. But the reality is that they have to buy the cheaper T-96 to save money, and put their existing old MBT's to good use.
The T-59 is an old MBT, but with proper upgrade and maintenance, it's still useful for training and reserve duties. China has over a dozen countries on its border, and not everyone is equipped with the latest tanks. If the PLA needs to allocate some tanks to troops stationed along "low threat" borders (Burma, Laos, Mongolia, etc), upgraded T-59's will probably be sufficient.
I also suspect that, though the 105mm gun isn't as powerful as the 120mm or 125mm used on newer tanks today, with good ammo (DU?) it'd probably penetrate the frontal armor of a typical T-72.
