The ''Shivalik'' class or Project 17 class is a class of multi-role frigates in service with the Indian Navy. They are the first stealth warships built in India. A total of three ships were built between 2000 and 2010, and all three were in commission by 2012.〔 The ''Shivalik'' class, along with the seven Project 17A frigates currently being developed from them, are projected be the principal frigates of the Indian Navy in the first half of the 21st century.〔("Capital Cruisers" ), ''Sainik Samachar'', Ministry of Defence (India), 15 March 2004. Adm. Madhvendra Singh, Chief of Naval Staff: ''"These would be the future ships of the Indian Navy and will be of the Shivalik class"''.〕 All ships of the class were built by Mazagon Dock Limited. The class and the lead vessel have been named for the Shivalik hills. Subsequent vessels in the class are also named for hill-ranges in India.〔 Originally conceived as a successor to the ''Talwar''-class frigates, the ''Shivalik'' class frigates feature improved stealth features and land attacking capabilities.〔 ==Design and description== ''Project 17'' was conceived in the 1990s to meet the Indian Navy's need for a class of stealthy frigates that were to be designed and built in India.〔(2003–04 Annual Report of the Ministry of Defence ), India.〕〔(MoD – Report on Major Activities, 2002–05 (doc) ), Ministry of Defence (India).〕 The Directorate of Naval Design (DND)'s specifications for the project called for a class of "5000 ton stealth frigates (Project 17) incorporating advanced signature suppression and signature management features".〔(The Corps of Naval Constructors – Building Self Reliance ), MoD Samachar, Ministry of Defence (India), 1 December 2006.〕 The first three units were formally ordered by the Indian Navy in early 1999. ''Shivalik''s design embodies many firsts in Indian ships. ''Shivalik'' is the first Indian naval vessel to use a combined diesel or gas (CODOG) propulsion system. The CODOG gearboxes were designed and built by Elecon Engineering. The main features of the class are its stealth characteristics and land-attack capability. The ships incorporate structural, thermal and acoustic stealth features.〔"Warship Building Prowess", ''FORCE'', January 2008, ((forceindia.net )).〕 The vessels use 10 gigabit LAN for their network. There has also been an increased emphasis on crew comfort in this class of ships with more spacious accommodation being provided. Also, INS ''Shivalik'' is the first ship in the Indian Navy with chapati- and dosa-makers on board.〔(【引用サイトリンク】url=http://www.telegraphindia.com/1100422/jsp/nation/story_12366830.jsp )〕 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「Shivalik-class frigate」の詳細全文を読む スポンサード リンク
