>Presently, the US is decreasing its artillery ammunition stockpiles. In 2020, artillery ammunition purchases decreased by 36% to $425 million. In 2022, the plan is to reduce expenditure on 155mm artillery rounds to $174 million. This is equivalent to 75,357 M795 basic ‘dumb’ rounds for regular artillery, 1,400 XM1113 rounds for the M777, and 1,046 XM1113 rounds for Extended Round Artillery Cannons. Finally, there are $75 million dedicated for Excalibur precision-guided munitions that costs $176K per round, thus totaling 426 rounds. In short, US annual artillery production would at best only last for 10 days to two weeks of combat in Ukraine. If the initial estimate of Russian shells fired is over by 50%, it would only extend the artillery supplied for three weeks. >The US is not the only country facing this challenge. In a recent war game involving US, UK and French forces, UK forces exhausted national stockpiles of critical ammunition after eight days. >Unfortunately, this is not only the case with artillery. Anti-tank Javelins and air-defence Stingers are in the same boat. The US shipped 7,000 Javelin missiles to Ukraine – roughly one-third of its stockpile – with more shipments to come. Lockheed Martin produces about 2,100 missiles a year, though this number might ramp up to 4,000 in a few years. Ukraine claims to use 500 Javelin missiles every day. >The expenditure of cruise missiles and theatre ballistic missiles is just as massive. The Russians have fired between 1,100 and 2,100 missiles. The US currently purchases 110 PRISM, 500 JASSM and 60 Tomahawk cruise missiles annually, meaning that in three months of combat, Russia has burned through four times the US annual missile production. The Russian rate of production can only be estimated. Russia started missile production in 2015 in limited initial runs, and even in 2016 the production runs were estimated at 47 missiles. This means that it had only five to six years of full-scale production. >If competition between autocracies and democracies has really entered a military phase, then the arsenal of democracy must radically improve its approach to the production of materiel in wartime The initial stockpile in February 2022 is unknown, but considering expenditures and the requirement to hold substantial stockpiles back in case of war with NATO, it is unlikely that the Russians are worried. In fact, they seem to have enough to expend operational-level cruise missiles on tactical targets. The assumption that there are 4,000 cruise and ballistic missiles in the Russian inventory is not unreasonable. This production will probably increase despite Western sanctions. In April, ODK Saturn, which makes Kalibr missile motors, announced an additional 500 job openings. This suggests that even in this field, the West only has parity with Russia. The US does not have the production capacity to wage a sustained war with russia for more than a few days. They aren't going to ramp up their production of advanced weapons to the levels needed in less then 5-10 years. The time it takes to assemble entirely new factories and equipment and train personnel. The underlying infrastructure is not there and vast swaths of the components are manufactured exclusively in china. You don't need just a missile factory. You need to build every factory down the supply chain to supply the components including the production facilities to mine and process the resources. None of which currently even exist in the US because they were all shut down and sold off with the equipment moved to china and asia. https://www.zerohedge.com/geopolitical/biden-better-buy-more-bullets Theres the original article with links to the numbers.
