Those look like procurement contract years/values. Actual deliveries usually lag a year, two or three.
I agree, also congress needs to maintain funding to make these a reality. When combined with the reconciliation funding of a potential $450 billion (some advocating for $600 billion) it seems as if there is some support to bring US defense spending to around 5% of GDP.
If they can maintain a defense budget of 5% of GDP then I think we will need to re-evaluate our assumptions on the future US defense posture. These targets for missile production are representative of a much more ambitious production capacity. I expect similar scaling in things like fighter and bomber procurement as well. F-15EX, F-35A, B-21 and F-47 would see not only large increases in rate of production but also number of platforms procured.
