perhaps so but within the errors are a number of serious issues to take home and correct. Your task is to separate the gold from the dross and adapt accordingly without trying to shoot the messenger
Without delving into classified info, I can’t give a good breakdown of why that article is utter tripe.
Sticking to some OS only topics:
The 777 is an airborne/airmobile gun. Ideally we would have sent the old 198’s, as we have thousands in storage - and while much heavier if you’re not moving much, it’s a solid gun. We move the 777 with Hummers (and now JLTV’s) when not slinging or dropping them, the weight savings comes at a cost - there is a lot of Titanium in it, and that’s not a cheap material, nor does some of its properties help for a howitzer frame.
It’s barrel life is fairly standard for a 155mm, the issue is do to numbers of guns the Ukrainians are generally having to fire a lot more rounds in a shorter period of time than ideal - so all their Arty is wearing out faster than anticipated (heat kills). A barrel that has say a 5k life span at a given rate will deteriorate faster when shot at a faster firing schedule as the heat retained in the barrel is not being dissipated like it would be if fired at a slower rate.
There are 3 types of Switchblades being used in Ukraine, the light one is fairly ineffective against armor - and that isn’t a surprise to anyone as it was designed to target soft vehicles or other unarmored targets.
Russia has been GPS jamming areas of Europe for over a decade now. There are ways around that - but keep in mind the majority of munitions supplied to Ukraine have been old stock - that doesn’t have counter GPS Defeat tech, and we are fairly tight on controls with that technology anyway.
So Ukraine has to play rock paper scissors and conduct counter EW missions - which NATO would primary do with air power, or use munitions with INS in them as well which isn’t as accurate as GPS combined with INS.
The GLSDB like the GMLRS has anti GPS spoofing via INS . But it’s a got 35lbs of explosives, and the bomb that tends to sink in the mud depending on season or when used in air burst mode, the lethal radius isn’t much either — I don’t think anyone who knows much about munitions expected it to be an overwhelming success/game changer. It was simply an extended range option compared to the older MRLS/HIMAR munitions provided. By far the most effective systems for HIMARS and MLRS have been the cluster submunitions, then the pre-fragmented tungsten.
The Abrams, well, no Abram’s crews where lost in the 7 lost tanks - the Russians have been targeting the blowout panels in the turret of most western tanks with their OWUAS systems - when you see what the Russians threw at those tanks, I don’t think the losses where unexpected, and on a cost benefit basis, I think the Russians spent a lot of time and money that they can’t recoup trying to get those tanks.
That’s pretty much the end of the OS takes from what I can see — but I think the author is a moron.
