The United States expended about 25% of its supply of advanced THAAD interceptors during the 12-day war with Iran, CNN reported citing two sources familiar with the details. According to the sources, during the campaign American forces helped defend Israel by using more than 100 THAAD interceptors - possibly up to 150. They said the rapid depletion of interceptor stocks has raised concerns in Washington about the U.S. ability to replenish and produce the missiles at the required pace.
