The entire Apollo program had a budget of $165.5 billion (in 2021 dollars), over a 10 year program. $16.5 billion per year. It's a big number, but it's absolutely dwarfed by things like a $600bn military.
Apollo was actually pretty close to the same GDP share (2.5% of GDP annually) as the modern defense budget (3.1% of GDP).
Inflation-adjusted numbers ignore that we have more people and more value produced per capita now than in the 1960s.
I don't have the numbers though.
Yes, the spending on the Apollo program is pretty close (as share of GDP) to the current military budget, not to the contemporary (1960s) military budget, which ranged from a 7.6-9.4% of GDP.
