>Army never had a lot of ATACMs to begin with as launching missiles at things is not really their job
It's called the Army tactical missile system FFS. It was literally built for them. It's rocket artillery!
We built only 3500 of the missiles total. We stopped investing in rocket artillery because they get very close to IRBMs, and those were banned until recently.
The Marines had some, but not anymore (IIRC). Other branches have zero. The replacement, PrSM is not in any serious production yet.
Other long range precision strike munitions include:
Tomahawk: 10k total production through all US history. We only fired 800ish total in all of the 2003 Invasion of Iraq. We have so far fired over 1000 in Iran. The immense "Shock and Awe" that the world drooled over during the Gulf War involved fewer than 300 Tomahawks.
AGM-158 JASSM: This is our bread and butter Air launched cruise missile (There isn't an air launched version of Tomahawk!). They only cost about $800k each! Lockheed claims they can someday build 1000 a year. We built 10k total. We fired 1100 in Iran so far and only have 1500 left.
AGM-86 ALCM: A 70s era cruise missile. We built 1800. We supposedly only have a few hundred remaining as nuclear tipped cruise missiles.
Donald Trump has fired over 2500 of our missiles in Iran, for no benefit, which represents a massive draw down of our long range precision munitions.
These numbers are literally public information.
