As the U.S. Patriot missile inventory has dwindled to fewer than 1,700, it has been confirmed that with the prolonged war with Iran, the U.S. military has been relocating air defense systems and precision weapons deployed in Asia and Europe to the Middle East in large numbers.

The New York Times (NYT) reported in its coverage on the 8th (local time) that the U.S. Department of Defense estimates it will take more than two years to replenish its weapons stockpiles, and that changes to the security environments in Ukraine, the Korean Peninsula, and across Europe have become inevitable in the process.

Consumption Rates and Inventory Shortages from the Iran Conflict

As the war with Iran has dragged on for nearly six months, thousands of U.S. high-value missiles and air defense weapons have been depleted. According to the NYT, the United States has used more than 1,500 Patriot missiles alone in operations against Iran, and given the current production rates of defense contractors, it will take at least two years to replenish the consumed stockpile. In particular, air defense missile inventories were significantly reduced in the process of responding to Iran's retaliatory attacks, and some weapons deployed in Asia and Europe were diverted to the Middle East.

Regional Security Impact

Ukraine — The weapons shortage has dealt an immediate blow to Ukraine. Ukrainian President Volodymyr Zelensky stated that air defense missiles received from the West this year have plummeted to one-third of last year's levels.

Asia — Some long-range weapons, including Tomahawk missiles, that were deployed in preparation for rising tensions with China, along with hundreds of advanced air defense missiles, are reported to have been moved to the Middle East. There are also concerns that as the U.S. Department of Defense concentrates reconnaissance and air defense assets in the Middle East, the deterrence capabilities of U.S. Forces Korea against North Korea could be weakened. Among U.S. officials, concerns have also been raised that allies such as South Korea and Japan, due to diminished confidence in non-nuclear forces, may consider the possibility of developing their own nuclear arsenals.

Europe — With weapons production stalled, allies are already seeking ways to diversify their procurement sources.

Strategic Implications and Analysis by U.S. Officials

U.S. officials explained that Russia and China are already aware that U.S. weapons reserves are limited, and that they also understand it will take considerable time for the United States to reconstitute the stockpiles needed for specific war plans. Experts at the Center for Strategic and International Studies (CSIS), a U.S. think tank, also warned that delays in rebuilding U.S. military readiness could influence the strategic calculations of China and Russia. The NYT analyzed that the U.S. military's missile inventory shortage could serve as a new variable affecting support for Ukraine as well as the security environments of the Korean Peninsula and Europe.

U.S. Department of Defense Rebuttal

Meanwhile, the White House warned of strong legal action against those responsible for leaking intelligence. The U.S. War Department dismissed reports of weapons shortages as inaccurate, stating that it 'has everything needed to strike at a time and place of the president's choosing.'
