[The First Round of U.S. Strikes on Iran Estimated to Cost $4 Billion] According to a report by Jinse Finance, German defense giant Rheinmetall estimates that the U.S. used up to $4 billion worth of ammunition in the first 72 hours of strikes on Iran. This included approximately 400 cruise missiles and 800 air defense interceptors. The company stated in its Wednesday financial report that these figures are based on 'public information and internal assumptions.' Other reports suggest that the cost of ammunition in the first two days of the conflict was even higher, reaching $5.6 billion.
