Israel and the United States have begun work on a new ballistic missile defense interceptor, the Arrow 4, amid heightened tensions in recent years over Iran’s increased missile capabilities.
The Arrow 4 will be the latest of the two country’s jointly developed ballistic missile interceptors, and is set to replace Arrow 2 in the coming decades, the US Missile Defense Agency announced Thursday. Meanwhile, the Arrow 3 will remain Israel’s highest-altitude interceptor, designed to knock down missiles beyond earth’s atmosphere in space.
