Iron Dome

Even some of the interceptor missiles for its own Iron Dome air defences are made in the US.

An executive order calling for the creation of what was initially termed the "Iron Dome for America" noted that the threat of next-generation weapons has "become more intense and complex" over time, a potentially "catastrophic" scenario for the US.

The president was referring to Israel's "Iron Dome" system, which the country has used to intercept rockets and missiles since 2011.

Israel's Iron Dome, however, is designed to intercept shorter-range threats, while two other systems - known as David's Sling and the Arrow - combat larger ballistic missiles such as those that have been fired by Iran and the Houthis in Yemen.

Ms Bazylczyk described the Iron Dome as geared towards "lower tier" threats, such as rockets fired from Gaza or southern Lebanon.
