of the Arrow 1, near the
Technion's Faculty of Aerospace Engineering.
Arrow 1 The first launch of the Arrow interceptor took place on August 9, 1990, designed to test the missile's control and guidance systems. The test came to a halt seconds after takeoff, and the missile was intentionally destroyed due to fears it might go off track and hit a settled location. This was caused by the failure of the ground tracking radars to track the missile's
trajectory. The Arrow 1 was reportedly a two-stage
solid propellant missile, with an overall length of , a body diameter of , and a launch weight of around . It was estimated that the second stage had a length of , and that it had
inertial and
command update mid-course guidance, with a terminal
infrared focal plane array. The missile was described as being relatively high-speed and maneuverable, with
thrust vectoring in both stages. The range capability has been described as around . On the other hand, the Arrow 1 could be a single stage missile. Reportedly, in June 2001 Arrow missiles were test-fired in the course of a joint American-Israeli-Turkish exercise code-named
Anatolian Eagle, in the southeast of Turkey. On August 27, 2001 (AST#6), the Arrow system successfully intercepted its target at some from shore, the highest and farthest that the Arrow 2 had been tested to date. In October 2002 the second battery was declared operational.
Block-2 A successful test of the Arrow 2 Block-2 took place on January 5, 2003 (AST#8). Four missiles were launched towards four simulated targets in order to examine the interceptor's performance during special flight conditions as well as system performance during a sequence of launches. The test was a success, with the interceptor destroying the "Scud" that flew a trajectory This was the twelfth Arrow interceptor test and the seventh test of the complete system, the first interception of a real "Scud". This significant test became known as the AST USFT#1. It detected the true target, but a technical malfunction reportedly prevented it from maneuvering to strike it, leading to a suspension of testing. Actual testing of the complete Arrow system was resumed in December 2005, when the system successfully intercepted a target at an unspecified but reported record low altitude.
Block-3 On February 11, 2007, an Arrow 2 block-3 successfully intercepted and destroyed a "Black Sparrow" target missile simulating a ballistic missile at high altitude. A precursor of the next block was launched without a target on March 26, 2007, to gather information on its flight and performance, introducing unspecified modifications to its hardware and
electronics and reduced manufacturing costs by some 20 percent.
Arieh Herzog, then Director of IMDO, has said: "Our Arrow operational system can without a doubt deal with all of the operational threats in the
Middle East, particularly in Iran and Syria."
Block-4 On April 15, 2008, the Arrow weapon system successfully detected and made a simulated intercept of a new target missile, and reportedly the
Iranian
Shahab-3 as well. In September 2008 the IDF attempted a test of actual Arrow 2 block-4 missile against the "Blue Sparrow". The drill had to be aborted, however, when the target missile malfunctioned shortly after launch. Eventually the Arrow 2 block-4 was successfully tested against the "Blue Sparrow" on April 7, 2009. A July 22, 2009, joint test of the Arrow 2 block-4 against an airborne target missile with a range of over once again at the NAS Point Mugu, was reportedly aborted in the final second before launch after the missile failed to establish a communications link. "Tracking of the target worked well, but tracking trajectory information that the radar transferred to the battle management center erroneously showed we would be out of the prescribed safety range, so the mission was aborted," a program source said. The aborted interception came after two earlier setbacks in the planned test, initially scheduled for July 17. The first try was scuttled due to a technical glitch in the C-17 aircraft, and a planned July 20 attempt was scrubbed due to a malfunctioning
electric battery that was not providing enough power to a key element of the Arrow system. The test was widely referred to as a failure, On February 22, 2011, the Arrow system successfully intercepted a long-range The test validated new block-4 versions designed to improve discriminating capabilities of the Arrow 2 interceptor. It was a body-to-body impact that completely destroyed the target. According to
Arieh Herzog, block-4 upgrades "improve the process of discrimination of what happens in the sky and the transmission of target data for much better situational control." On September 9, 2014, an intercept test was conducted over the Mediterranean Sea with block-4.1 versions of the operational system. The outcome was inconclusive and remained so until the data was fully analyzed. In February 2015, an official at the IMDO acknowledged that a test was successfully acquired, but narrowly missed its target.
Block-5 By April 2011, IMDO launched the initial definition of a new Block-5 upgrade to the complete Arrow system that will merge the lower-tier Arrow 2 and exoatmospheric Arrow 3 into a single national missile defense system. According to Arieh Herzog, the planned block-5 will include new ground- and airborne sensors, a
command and control system, and a new target missile – the
Silver Sparrow The planned Block-5 will optimize the existing Super Green Pine radar to operate with the AN/TPY-2 radar as well as with radars commanding anti-ballistic missiles aboard
United States Navy destroyers. U.S. radars will be used to support
closed-loop operations if Israel and U.S. targets in the region come under attack.
Arrow 3 By August 2008, the United States and Israeli governments had initiated development of an upper-tier component to the Israeli Air Defense Command, known as Arrow 3. The development is based on an architecture definition study conducted in 2006–2007, determining the need for the upper-tier component to be integrated into Israel's ballistic missile defense system. According to Arieh Herzog, the main element of this upper tier will be an exoatmospheric interceptor, to be jointly developed by
IAI and
Boeing. Arrow 3 was declared operational on January 18, 2017. Arrow 3 operates at greater speeds, In early 2021, Israel revealed that the development of the Arrow 4 interceptor was ongoing and that the system was targeting the interception of hypersonic threats such as
hypersonic cruise missiles and
hypersonic glide vehicles. Efforts to counter hypersonic threats took on new urgency following a November 2022 announcement by Iran that they had tested a hypersonic missile which can reach Israel within four minutes. ==Specifications==
