The “Arrow” anti-ballistic missile program, is a joint project, financed and designed between Israel and the United States that began in 1986 to get a more effective missile against ballistic threats than the MIM.104 Patriot. In 1990, after the dubious anti-ballistic capabilities of the Patriot during the Gulf War, it was decided to accelerate the project and the first effective interception of a missile was achieved in June 1994. The Arrow-1 was a basic test missile, with the Arrow-2 being the first version to enter service with Israel in 2000. Currently the Arrow-2 Block.5 is the most modern in service, although the Arrow-3 has been declared operational in 2017 and the Arrow-4 is already under study. The Arrow program has cost about 2,600 million dollars for the American side and nearly 2,000 million for Israel until 2016.
