First used in the 1991 Gulf War, the US Patriot air defence system has seen demand spike sharply this year, with supplies of interceptor missiles depleted by Ukraine’s war against the Russian invasion and the widening war in the Middle East.
Patriot, short for Phased Array Tracking Radar for Intercept on Target, is a mobile surface-to-air missile defence system built by US weapons maker Raytheon Technologies that can be used in all kinds of weather and at long range.
A typical battery includes radar and control systems, a power unit, launchers, and support vehicles. The system can intercept aircraft, tactical ballistic missiles and cruise missiles, depending on the interceptor used.
Specific inventory numbers are classified, but CSIS estimates that about 65 per cent of US Patriot interceptors were expended between February and July, with less than 850 left on hand, down from 2,330 before the Iran war began.
