US security-policy journal; analysed how the Iran war depleted US Patriot stocks available for Ukraine
By lens · 1 takes across the edition
Foreign Policy quantified the Patriot stock competition between the Iran war and Ukraine: the US entered the Iran campaign with an estimated 2,330 Patriot interceptors and has consumed roughly half in five months of active air-defence operations, directly competing with Ukraine's need for 2,000 interceptors per year. The piece argues this stock depletion explains why the 570-weapon July 2 salvo succeeded in breaking through with 25 ballistic missiles, and predicts further exploitation of the gap before JUMPSTART production can fill it.
