Spare parts for 105mm Howitzers and other equipment
The story of the U.S. weapon support for Ukraine is one of diminishing quantity and quality. First the U.S. gave 143 M-777 155 mm systems to Ukraine. These proved to have a high breakage rate and were also easily targeted.
Then the U.S. had run out of 155 mm ammunition it could give away. It next offered 36 105 mm howitzers and 180,000 105mm rounds. Same story.
After that came the 120 mm mortar. Artillery is usually fought against with counter artillery. When battle radar pics up a flying artillery round one can calculate where its has been fired from. Then a dedicated counter artillery battery, usually with longer range, will be tasked to fire at that position. In a good organized unit that takes less than one or two minutes.
The M-777 guns have a firing range of about 20 kilometers. That is somewhat equal to 152 mm guns the Russians are using. The 105 mm guns came next. Their range is about 11 kilometer. The 120 mm mortar can reach about 7 kilometer.
Aside from HIMARS Ukraine’s front artillery has become smaller with less reach than those systems used on the other side. That will make it easier to counter it. Ukraine also has an acute lack of ammunition for those few weapons that still exist. It has long lost the artillery war.
The war in Ukraine is waged on an industrial level. But the ‘west’ and its Ukrainian proxy are not prepared for industrial warfare. In a longer piece - It’s War, Josep, But Not As We Know It - Aurelian explains why that is the case:
Posting to an idiot, who doesn't know that Burisma's owner, Mykola Zlochevsky, is a pro-Russian oligarch who served as a minister under the Russian-puppet Viktor Yanukovych, is in no position to come up with a chart on Ukraine.
