This is going to be a long thread 🧵on artillery logistics in the Ukraine war. It will explain what we should be seeing, but are not.
To get there, I need to start with calling myself out with being wrong and why I think that was.

It turned out the Russians refusal to use artillery on Ukrainian counter-attacks at Izyum had to do with a large set piece artillery barrage the Russians had planned to open their Donbas offensive across the entire front.

The logic chain of that thread fell apart on that point.
It also helped I had been tipped off about coming a coming article saying there was a Russian shortage in 160mm & 240mm mortar ammo because of the heavy use of those calibers in Syrian cities.

You can now file this under "Trent Telenko can be wrong."
There were additional factors besides those two points that gave me a context to reach that conclusion.

Back in late 2014 I joined a Ukrainian diaspora email list covering the Donbas war. At the time I was studying the 1945 artillery battle at Okinawa.

This dud rate is better than the oldest Ex-Soviet stuff seen in Afghanistan (~30%), but not the less than 5% rate of duds seen in older Western ammo.
Acronyms:
UXO - unexploded ordnance
KIA - Killed in action
WIA - Wounded in action.

A shell fuze is an explosive train from smaller to largest of a primer, a detonator and a booster charge meant to set off the main bursting charge of a shell

Generally, as artillery fuzes age, they get less reliable. This is because the chemicals in the Fuze's primer are the most unstable & subject to degrading over time.
Artillery ammunition of all sorts has a life span.
Highly energetic solid explosives & propellants degrade

An 18% dud rate on Smerch rockets is a symptom of the aging of the primer in the rocket fuze, AKA a time expired munition.

There were other indications of "time-ex" Russian artillery rocket munitions from the 2015 122mm Grad rocketing of Mariupol.
As rocket propellent ages, it generates marginally & unpredictably less thrust.

Soviet Union's strategic reserve of artillery ammunition used up.
When the US Military overran Iraq in 2003. It found more artillery ammunition, mostly ex-Soviet, than in it's own war reserves.
These Iraqi munitions were destroyed in the US anti-IED campaign of 2004-2007.

The radar proximity "VT-Fuze" debuted for the first time in Pacific ground combat at Okinawa.

The impact marks of high speed fragments thrown from an airburst shell look different than ground & delay fuzed shell bursts.

Please note, there are no craters. There are only wide u-shaped fragment patterns.

Airburst shells are infinitely superior to ground or delay bursts because they will kill infantry in trenches without overhead cover.
They are also much better at killing trucks as this US Navy 5-inch gunfire test shows.

Finally, this video shows a near miss of a Ukrainian trench line by a Russian impact fuzed shell.
If it had been a time or proximity fuzed shell, the fragments would have killed the soldier taking the video.

So what is this lack of Russian & Ukrainian airburst fuzing mean?
Good fuzing is expensive, requires high end manufacturing capability & quality control.
Russian artillery simply doesn't have either available.
See this time mortar fuze from Taiwan.

The replacement of chemical percussion, mechanical, and electromechanical fuzing with pure electric-electronic fuzing for superior shell performance is a 21st Century trend Russia is ill prepared to follow.
Taiwan is just one example of this.

But the best way to upgrade Ukrainian artillery is going to be with NATO & other artillery fuzes to give Ukraine more airburst and other options versus Russia.
And the fuze that will help Ukraine the most is the ATK precision guidance kit fuzes for its incoming NATO 155mm

The PGK turns ordinary 155mm shells into precision guided artillery projectiles (PGAP) at the cost of 10% of maximum range.
You can airlift 40 PGK for the weight of a single Excalibur guided artillery shell.

The PGK requires minimal additional training to properly use and it will vastly reduce the required artillery shell tonnage for the same battlefield impact.
The only reason it cannot be used on current Ukrainian shells is they have the Russian 36mm fuze threads compared

...to the 45mm used on NATO artillery shells.
So the UA would have to take 152mm and 203mm casings and machine out the threads to fit the PGK NATO fuse thread.
Ukraine has a plant in Sumy that manufactures 122mm, 152mm ammo, so this is not an unusual challenge for them.

It is the little things in war that make all the difference.
Things like shell fuzes.
Why we have not seen the Western intelligence notice or Defense Departments & Defense Ministries to go there with upgrading Ukrainian artillery and mortar fuzes is a mystery...
