Pentagon estimate to Congress (reported 18 Sep 2026) replaces CBO $38B (to 1 Aug). The extra $1.5B 'set aside for supplementary fuel needs' (giving the $45.1B headline) is excluded as a reserve, not a cost incurred. Includes interceptors used defending Israel in 2026. No later official figure found as of 5 Oct 2026; CBO projects $2-3B per month going forward.
