David's Sling ((ヘブライ語:קלע דוד)), also sometimes called Magic Wand ((ヘブライ語:שרביט קסמים)), is an Israel Defense Forces military system being jointly developed by the Israeli defense contractor Rafael Advanced Defense Systems and the American defense contractor Raytheon, designed to intercept medium- to long-range rockets and cruise missiles, fired at ranges from 40 km (24.85 miles) to 300 km (186.41 miles).〔https://fas.org/sgp/crs/mideast/RL33222.pdf〕 David's Sling is meant to replace the MIM-23 Hawk and MIM-104 Patriot in the Israeli arsenal.〔(Israeli Patriot Replacement ) - Strategypage.com, 13 December 2012〕 It is designed to intercept the newest generation of tactical ballistic missiles, such as Iskander, using an on-board dual CCD/IR seekers to distinguish between decoys and the actual warhead of the missile, in addition to tracking by Elta EL/M-2084 Active electronically scanned array multi-mode radar.〔(Israel Missile Chronology ) Nuclear Threat Initiative, 2010〕〔''New Israeli Anti-Rocket Projects Move Ahead'', ''Aviation Week & Space Technology'', Robert Wall, 06/23/2008〕 The multi-stage interceptor consists of a solid-fuel, rocket motor booster, followed by an asymmetrical kill vehicle with advanced steering for super-maneuverability during the kill-stage. A three-pulse motor provides additional acceleration and maneuverability during the terminal phase.〔''Missile-Killing Interceptors Eyed By Israel, US'', Aviation Week's DTI, David A. Fulghum, 23 September 2010〕 David's Sling was planned to be deployed in 2015, but budget shortfalls for infrastructure for deployable missile batteries will delay its operational date. David's Sling is meant to bolster the second tier of Israel's theater missile defense system. The two-stage radar and electro-optic guided system has a 70-300 kilometer range, three times that of Iron Dome. The system can be deployed against aircraft and missiles, with plans to convert the system to intercept cruise missiles in the future. The name David's Sling comes from the biblical story of David and Goliath.〔http://www.usatoday.com/story/news/world/2012/11/13/israel-missile-defense-system/1703221/〕 ==Development== The interceptor is a two-stage missile, with two targeting and guidance systems installed in its nose-tip (a radar and an electro-optical sensor). In 2006 Rafael was awarded a contract to develop a defense system to counter the threat of medium- to long-range rockets with ranges between 70 km and 250 km. In order to enable Israel to make use of the financial aid provided by the United States to further develop the system and to produce it, a partnership was established with Raytheon which will develop the missile firing unit and overall logistic system and assist Rafael with developing the interceptor. In some of Raytheon's publications, the interceptor is referred to as "Stunner". In November 2012, David's Sling was expected to enter operational service in 2013 or 2014. David's Sling owes much to the SPYDER programme's modified Python 5 and DERBY seeker technology .〔 The increasing danger of rocket and missile fire against Israel (Qassam rocket fire from Gaza, Katyusha rocket fire from southern Lebanon, and Iran's ballistic missile arsenal) has led to the development of defense systems to counter this threat. In addition to the David's Sling system, which is designed to intercept medium- and long-range rockets, the Iron Dome system, a separate system with which it will be used in conjunction, designed to intercept short-range rockets (4–70 km), and the Arrow missile, a separate system designed to intercept ballistic missiles, are already in use. On 25 November 2012, Israel successfully tested the Stunner interceptor missile. The David's Sling battery, stationed at an undisclosed desert location in Southern Israel, fired and destroyed the incoming missile with a two-stage interceptor. In late November 2014, the IDF revealed that the David's Sling system would soon be deployed in various areas around Israel for a trial period before becoming operational. Initial trials will focus on its ability to intercept short and medium-range rockets and missiles with a range of coverage three times greater than Iron Dome. After that, the system needs to undergo two further trials, testing its ability to intercept aircraft and longer-range missiles and then cruise missiles. David's Sling will be linked up to the Home Front Command's command and control systems, as well as also having its own independent interception management center.〔(Israeli-made David Sling air defense missile system will be soon deployed for trial period by IDF ) - Armyrecognition.com, 30 November 2014〕 In February 2015 Israel asked US Congress for $250M in additional assistance in producing David's Sling. US Companies that would be awarded contracts include Raytheon Co.; Arlington, Virginia-based Orbital ATK Inc.; and Falls Church, Virginia-based Northrop Grumman Corp.〔(Israel said to seek additional $300 million from US for missile defense ) - TimesofIsrael.com, 28 February 2015〕 Other defense website reported that Israel has requested US funding $150M for the procurement phase, which will include two systems controlling multiple fire units, covering the entire area of Israel.〔(Following a successful test series David’s Sling to become operational this year ) Defense-Update.com, 1 April 2015〕 From still other sources, development cost for David's Sling was capped to around $250 Million dollars so far. The $150 Million request is for initial procurement of one or two batteries. Since two batteries can cover the whole territory of Israel it is clear that Israeli initial procurement will start with just two batteries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「David's Sling」の詳細全文を読む スポンサード リンク
