From what I can tell the Leopard 1A5HEL is part of an actual upgrade program, unlike the M60HEL which is currently just a proposal, so we should at least see a prototype for the former at some point in the future.
At the very least I know that Greece is also amidst an upgrade program for the M163.
IMO I feel like they should’ve done this especially with the new gun but either way its pretty sick to see the new composite armor and RCWS integration. At the least swapped in the D2’s new gun from the old 105mm M68.
it is planned, using new gun replacing m68. and the D2 turret version is not just C&P, the protection will be buffed to about 300mm ke similar to original M60 turret with additional armor.
My big thing is I always hated when country’s just put composite armor over the existing turret and call it “advanced”. I feel like it wastes space that could introduce better armor, more electronics, and more stowage for munitions. Not to mention, in this case the new 105mm would be a LOT better for overall accuracy. At least if it was ERA it’s modular and can be replaced. I think the one vehicle that had done it well with armor casing is the M60T/Sabra II.
for D2 turret, I think it’s just big. D2 turret is not a good design.
none of this is included, and more expensive.
both kinds of turret just aims for defending RPG and autocannon. so the old turret version is more reasonable.
as for electronics, FCS and gun, they share same things
