U.S., Israel Test Arrow Block 4 missile ARLINGTON, Va., Feb. 10 (UPI) -- The United States and Israel have flight tested the Arrow Weapon System to evaluate and verify the missile system's Block 4configuration. The test, conducted over the Mediterranean Sea, was a target-only exercise in tracking a target and was conducted by the U.S. Missile Defense Agency and the Israeli Missile Defense Organization. "The success of the test is the final test before delivery of the Block 4 Arrow Weapon System," the MDA said. This was a major milestone in the development of the Arrow Weapon System and provides confidence in operational Israeli capabilities to defeat the developing ballistic missile threat. The first Arrow missile, for theater defense against ballistic missiles, came into service with Israeli forces in 2000. The Arrow was designed by Israel Aerospace Industries and is manufactured by IAI and Boeing. The United States and Israel signed an agreement for the system's funding in 1998. The U.S. MDA said that during the test, the AWS' fire control radar tracked a Blue Sparrow target missile and then transferred information to a battle management controller, which prepared a simulated intercept solution.
