It is easy to gauge how much goes to military spending. Practically all of it if we go by previous years: https://en.wikipedia.org/wiki/File:US_aid_to_Israel.gif

And of that military spending, IIRC >=50% is only allowed to be spent on purchasing from US companies (i.e. driving US military innovation) and IIUC from 2019 onwards that percentage will go up to 100%, so it will primarily drive US military innovation (and at the same time discourage Israeli military innovation, since the Israeli government will be less likely to spend money on local military products)
