The US-Iran conflict has escalated into an open military war, raising concerns about its potential financial impact on the US. The operation, named Epic Fury, has already seen significant spending, with estimates ranging from $779 million in the first 24 hours to over $33 billion in total US spending connected to the conflict since 2023. The US has deployed a wide array of advanced weapons systems, including stealth bombers, fighter jets, drones, and missile defense systems, at a potential cost of billions more. However, experts caution that the financial sustainability of the operation may not be the primary concern, as the US has a substantial defense budget and a vast arsenal of weapons. The real challenge lies in the inventory of interceptors and the manufacturing pace of replacements, which may not be able to sustain the current pace of operations indefinitely.
