thought you would like that collection. Sadly this has been something we've hit back and forth since March of last year. Well finally you are seeing the results of your long held view on russian artillery. Took longer than either of us thought but now it is clearly here. They cannot keep these losses up and I would think that soon the only self propelled artillery will be the old t62/t55 tanks. Far cry for a 203mm mortor of 152mm SPG
It did take a while. The shell weight for a tank gun used as artillery is not as much as for the average howitzer, but the biggest problem for tanks used as artillery is the limit of gun elevation. Because the gun can't elevate as far, the range is limited. Russia is going to face the same problem with tank artillery that they have with their artillery now. The tanks will have to get suicidally close to the front lines to fire.
What is the obstacle to manufacture of artillery barrels?
Gun barrels require a special alloy of steel to make and special tools are required to bore out the barrels. After the USSR collapsed the Russians allowed the old Soviet artillery production to whither and die since there were so many guns in storage. I believe the artillery gun barrel manufacturing was mostly done in Ukraine which was now another country.
Today there are very few companies that make the machine tools to make large gun barrels. I believe the biggest is in Germany. The machine tool makers who can make these tools is limited outside the west. Even China imports a lot of their machine tools from the west.
Russia does make tank gun barrels for their T-90 production, but the rate is about 250 a year. They have been selling most of those to other countries before the war. They were a source of income for the country. They made a handful of barrels for the 2S35 Koalitsiya-SV next gen howitzer. They made 12 of them. The only artillery production in about 20 years.
Like the T-14 tank, Russia was trying to get a foreign buyer to get the artillery piece into production. The Russian arms procurement system is set up so they need a foreign buyer before they can put any new arm into production. If no buyer comes forward, the weapon stays in the prototype stage.
Russia could switch over their limited barrel production capacity to howitzer barrels, but they would have to shut down tank production. They have been talking about increasing tank production to 1500 a year, but so far there is no indication that production has increased at all. Probably because there are many bottlenecks preventing production increase, including limited barrel production.
Is North Korea a viable/plentiful source for artillery and shells? Putin was meeting with his North Korean buddy for a minute.
Russia has already received artillery shells from North Korea. Their storage is poor and the shells Russia received were in poor condition. Russians were posing photos on Telegram.
Both NK and SK have a lot of artillery. It's assumed that if the Korean War kicked off again that artillery would play a significant role.
Nobody knows for sure how many guns the NK have or what condition they are in. But they have a number of different types.
