The United States has used a large portion of its stockpile of highly accurate long-range missiles during its five-month war with Iran, raising concerns about the country’s military preparedness for future conflicts, according to a Reuters report citing people familiar with the data. The report said the U.S. Army has used much of its inventory of Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM), two of its key surface-to-surface weapons. According to two of the sources quoted by Reuters, the military has used “virtually all" of these missiles. Key missile stocks under pressure Reuters reported that the extent to which the U.S. military has depleted its ATACMS and PrSM stockpiles had not been reported previously. The long-range weapons allow the military to strike targets accurately from a safe distance.
ATACMS supplied by the United States have also played a significant role in the Ukraine war by enabling Ukrainian forces to hit targets inside Russia. The PrSM is the newer generation missile that is expected to replace the shorter-range ATACMS. Experts told Reuters that these missiles, each costing more than $1 million, would also be critical in any future conflict involving China. However, how many missiles remain in U.S. stockpiles remains unknown. Trump, Pentagon defend military readiness President Donald Trump launched the Iran war jointly with Israel in February, saying the conflict would be short. However, as the conflict has continued, three people familiar with the matter expressed concern that declining missile stocks could weaken America’s ability to deter rivals such as Russia and China. A fourth source said Central Command had nearly exhausted the land-based missiles available before the war but had replenished supplies using stockpiles from other parts of the world. Responding to Reuters, Trump said the United States still had “far more munitions than anyone in the world" and “far more than we need." He added that American defence companies were producing more munitions than ever before while expanding manufacturing facilities. Pentagon chief spokesperson Sean Parnell also defended the military’s preparedness, saying the U.S. remained fully capable of carrying out operations whenever required.
