Akash (Sanskrit: आकाश Ākāśa ''"Sky"'') is a medium-range mobile surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO), Bharat Dynamics Limited (BDL) for Missile Systems, Ordnance Factories Board and Bharat Electronics (BEL) for other Systems in India.〔〔(AkashSAM.com )〕 The missile system can target aircraft up to 30 km away, at altitudes up to 18,000 m.〔(Asian tribune: Upgraded version of ‘Akash’ test fired; By Hemanta Kumar Rout )〕 It has the capability to "neutralise aerial targets like fighter jets, cruise missiles and air-to-surface missiles" as well as ballistic missiles.〔(Akash missile successfully test fired for second day, ''Dated:November 18, 2014'' )〕〔(India Successfully Test Fires Medium-Range Akash Missile )〕〔http://articles.timesofindia.indiatimes.com/2007-12-13/india/27973517_1_akash-missile-nuclear-capable-multi-target-missile Nuclear-capable Akash missile test fired〕〔http://www.army-technology.com/projects/akashsurfacetoairmis/ kash Surface-to-Air Missile System, India〕 It is in operational service with the Indian Army and the Indian Air Force. An Akash battery comprises four 3D passive electronically scanned array radars and four launchers with three missiles each, all of which are interlinked. Each battery can track up to 64 targets and attack up to 12 of them. The missile has a high-explosive, pre-fragmented warhead with a proximity fuse. The Akash system is fully mobile and capable of protecting a moving convoy of vehicles. The launch platform has been integrated with both wheeled and tracked vehicles. While the Akash system has primarily been designed as an air defence SAM, it also has been tested in a missile defense role. The system provides air defence missile coverage for an area of 2,000 km². The Indian military's combined orders of the Akash, including radar systems (WLR and Surveillance), have a total worth of 23,300 crore (US$4 billion).〔〔(Akash Missile Users Give Feedback To DRDO | AVIATION WEEK )〕〔http://www.aviationweek.com/aw/generic/story_generic.jsp?topicName=india&id=news/awx/2011/03/25/awx_03_25_2011_p0-301846.xml〕 ==Development and history== Mark-I The first test flight of Akash missile was conducted in 1990, with development flights up to March 1997. Two Akash missiles intercepted two fast moving targets in simultaneous engagement mode in 2005. 3-D Central Acquisition Radar (3D-CAR) group mode performance is also fully established.〔(【引用サイトリンク】title=IAF initiates process for inducting Akash and Trishul SAM's )〕〔(【引用サイトリンク】title=Defense19 )〕 The Akash Missile Development cost of 1,000crore (€150 million; $200 million), including the project sanction of 600 crore (€90 million; $120 million), is 8-10 times lower than the cost of similar system developments in other countries. Akash has certain unique characteristics like mobility, all-the-way-powered flight till target interception, multiple target handling, digitally-coded command guidance and fully automatic operation.”.〔 Mark-II As reported on June 11, 2010, Akash Mk-II version has begun development and will be ready for a first flight in 24 months. The Akash Mk-II will be a longer-range, faster and more accurate SAM. The missile will have an intercept range of 30–35 km and increase in the accuracy of the missile's guidance system and the fire control system. Putting a seeker on board to allow the Akash Mk-II to operate over a larger profile is one of the options being considered.〔(【引用サイトリンク】title=Saurav Jha's Blog : Interview with Dr Avinash Chander, DRDO Chief and Scientific Adviser to Defence Minister )〕 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「Akash (missile)」の詳細全文を読む スポンサード リンク
