Patriot missile demand surges as global interceptor stocks run low
Global Patriot interceptor supplies are strained by Ukraine's war and Middle East conflicts, prompting urgent requests for replenishment.
The U.S.-built Patriot air defense system, a mainstay of modern missile defense since the 1991 Gulf War, is facing unprecedented demand. Interceptor missile supplies have been heavily depleted by Ukraine's fight against Russian strikes and by the expanding conflict in the Middle East, according to defense analysts and industry data.
Ukraine has repeatedly asked for more Patriot interceptors to counter nightly Russian ballistic missile attacks. At the same time, the war involving Iran has drained stockpiles in the U.S. and Gulf states, while several European nations are retaining missiles for their own defense needs.
What is the Patriot system?
Patriot stands for Phased Array Tracking Radar for Intercept on Target. Built by Raytheon Technologies, it is a mobile, all-weather, long-range surface-to-air missile system. Developed in the 1980s and modernized since, it is expected to remain operational through 2048. A typical battery includes radar, control systems, power units, launchers, and support vehicles, and can engage aircraft, tactical ballistic missiles, and cruise missiles depending on the interceptor used.
Capabilities and interceptors
The system's effectiveness depends on the missile type. The older PAC-2 interceptor uses a blast-fragmentation warhead, while the PAC-3 family employs hit-to-kill technology for direct collision. Raytheon produces the PAC-2 GEM-T, effective against short-range ballistic missiles, cruise missiles, and aircraft. Lockheed Martin builds the advanced PAC-3 MSE, capable of engaging longer-range ballistic missiles, cruise missiles, aircraft, and hypersonics. In July, Lockheed unveiled a lower-cost PAC-3 ACE interceptor.
The radar can track up to 100 targets simultaneously within a range exceeding 150 km. In May 2023, Ukraine reportedly used the system to shoot down a Russian Kinzhal missile, which Moscow claims is hypersonic. Ukraine said in January it had destroyed 250 targets, including 140 ballistic missiles, though exact figures are closely guarded.
Global usage and costs
Raytheon has delivered over 240 Patriot fire units, and thousands of interceptors have been manufactured. Nineteen countries operate the system, including the U.S., Germany, Poland, Ukraine, Japan, Qatar, Saudi Arabia, and Egypt. Sixteen nations field the newest PAC-3 MSE missiles, and six to eight countries have requested additional missiles to replenish stocks.
A single new Patriot battery costs over $1 billion, including about $400 million for the system and $690 million for its missiles. PAC-3 interceptors are priced at roughly $4 million to $5 million each.
Why supplies are running low
Exact inventory numbers are classified, but the Center for Strategic and International Studies estimates that about 65% of U.S. Patriot interceptors were used between February and July, leaving fewer than 850 on hand, down from 2,330 before the Iran war began. Gulf state inventories are also severely depleted, and several European countries have transferred some supplies to Ukraine.
The U.S. is in talks to allow Ukraine to produce Patriot interceptor missiles, including an option for Ukraine to build components for final assembly in Europe. Last month, the U.S. Army awarded Lockheed Martin a contract worth up to $58.6 billion for Patriot interceptor production.
