The United States has used nearly all of its available Army Tactical Missile Systems and Precision Strike Missiles during the five-month war with Iran, according to a Reuters report based on interviews with people familiar with internal military data. The weapons allow U.S. forces to strike distant targets accurately while reducing the need to send pilots into heavily defended airspace.
The report also said the United States has used a little less than half of its worldwide Tomahawk cruise-missile supply since the war began. The people who described the stockpiles did not disclose how many missiles remain, and Reuters said it could not independently verify the Tomahawk figure.
Officials and analysts are concerned that diminished supplies could limit the military’s ability to respond to another major international crisis. A separate estimate from the Center for Strategic and International Studies found that substantial portions of the nation’s Patriot and THAAD defensive-missile inventories also have been expended during the conflict.
The White House disputed concerns about readiness, saying the country has more munitions than it needs and that defense manufacturers are expanding production. Pentagon spokesperson Sean Parnell likewise said the military retains a deep arsenal capable of protecting U.S. interests.
