Now the question is: How many of those are going to Ukraine?

Even if none of the shells go to Ukraine it still increases the supply at a time when there is high demand for 155 ml shells and please realize that before this war started, there were few plants making these shells. Supply and demand are the name of the game.  Also, the EU initiative concerned with supplying ukraine with artillery shells was started because Ukraine couldn't buy it's own shells on the market because prices were so high. The increase in supply will keep that from happening to some extent. 

The US should be sending older shells to Ukraine and replacing their inventory with newer shells made in Scranton PA.

lol, putin I throwing together some new units to evict Ukraine from kursk, and he didn't supply the new troops with artillery. That's really surprising since mordor loves artillery I'm it's warfare. His new units will probably have horrible losses lmao and they can get wrecked

Raytheon has been hit with a $200 million fine for sale of military equipment to Russia. Shame on Raytheon. Defense contractors should be especially mindful of the bigger picture and not aid the enemy. Also, good job on Biden administration for enforcing this against American companies.
