Israel said on Thursday it is developing a new ballistic missile shield, the Arrow-4, with the United States, another layer in a defensive system built with an eye towards Iran.
Israel's Arrow-2 and Arrow-3 interceptors are already operational as part of a multi-layered system to destroy incoming missiles in the atmosphere and in space.
"The development of Arrow-4 together with our American partners will result in a technological and operational leap forward, preparing us for the future battlefield and evolving threats in the Middle East and beyond," Defence Minister Benny Gantz said in a statement.
