What spare parts? Whenever a Dutch howitzer breaks down they have to scavenge parts from another vehicle(s). The way the German army has been screaming about the state of spare parts in the Bundeswehr for years (decade+ ?) with zero improvement forget about it. The Italians can't be off any better.
So it's an over-engineered howitzer requiring frequent highly technical maintenance with little to no spare parts in storage and ramping up production ... nah. Very few built, so scavenging isn't going to last very long either and will radically strip various of the larger NATO member states of fire power. The thing has a reputation for breaking down frequently even among NATO crews, and that's under peace time conditions with few rounds being fired at all never mind in limited time high volume with actual support infrastructure tuned to service the thing.
Soviet/Russian equipment doesn't last very long, that's why they built so much of the stuff. Their equipment doctrine has significant losses factored into both the design and the use of their systems because they knew and know that a large scale war chews up equipment and spares which European bean counters gladly ignored in order to be able to report to their political masters that they had saved another 300 million on "excess" defence spending. Simple mediocre guns in massive numbers that keep firing and are easy to maintain will defeat handfuls of supreme guns that require a thorough overhaul by expert technicians ever couple of hundred rounds. If a howitzer gets properly hit it's destroyed regardless of whether it's a 2S3, 2S5 or PzH2000. The problem is we ain't got the numbers of PzH2000s or the parts in storage to play that game. This is a war of attrition, not lobbing a round or two a day at some jihadist in his mud hut.
Replace with towed artillery? A lot of NATO members got rid of them and stuck/replaced with small numbers of self-propelled pieces. The Russians were smart enough to retain both because the towed piece from 1960 is still better than having no artillery at all after a couple of months of fighting.
During WW2 the allies didn't build Gucci vehicles either, they built the things that could be built in large quantity and be "good enough" whereas the Germans toyed around with unfeasible designs for tanks, tank destroyers and SPGs alike.
excuse me, but I think this is a total misinterpretation of the facts.
German Gucci stuff: it was just that modern technology and German morale and training had brought a bloody harvest to the Russian ranks.
And the western stuff, with a few exceptions (heavy tanks, V-2 Me-262) was much more Gucci than the German stuff, and was made in their thousands. War economy, right.
Temporary superiority was achieved by the Germans, but already in 1944 many development projects that would have surpassed them were cancelled: there was no need for them, and then came the generational leap in military technology.
In Ukraine, on the Kiev front, partly because of military geography, the more modern equipment, which was only part of the armament of the Western armies (Nlaw, Javelin, drones, combined with the remaining Ukrainian equipment), drove the Russians out of Ukraine.
The presence of a minimal amount of more modern anti-ship systems and precision weapons has cancelled the siege of Odessa, now they have had to give up their plans to block grain shipments.
Donbass: the Russian doctrine so beloved of the two-bit Russian fans: in a matter of weeks they managed to take control of an area about the size of a Hungarian county, using an incredible amount of munitions (logistics hello, this is the only place where they could bring the Russian plans to transport munitions by rail to the front)
- the Ukrainian defenders didn't get the systems they needed until july, because first the western leadership thought it was still 2014, then they believed the Russian blackmail about the deployment of WMD.
Last month, truly modern Western heavy weapons technology arrived in small numbers, the event is known.
And no , the Russians don't have infinite reserves either, the real capacity of their military complex is a fraction of that of South Korea.
Taiwan: .i'm sure if the yellows tried it and America decided to get in on the act, the Chinese fleet, feared in the media, would be subject to the same as the Russian armoured columns under Kiev
