Interceptor missiles are in high demand as Israel and U.S. allies are facing a growing threat from Iran, and the shortfall may become even more critical after Israel's weekend retaliatory strikes on Iran if Tehran responds with more attacks.

The most common interceptors are the Standard Missiles being used to defend Israel from Iran and to stop Houthi rebels' attacks in the Red Sea. U.S. officials say more than 100 Standards have been launched since last year's Hamas attack on Israel.
