The Archer Artillery System or Archer - FH77BW L52 is an international project aimed at developing a next-generation self-propelled artillery system for Sweden and Norway. The heart of the system is a fully automated 155 mm/L52 gun howitzer and a M151 Protector remote controlled weapon station mounted on a modified 6×6 chassis of the Volvo A30D, all-terrain articulated hauler. The crew and engine compartment is armoured and the cab is fitted with bullet and fragmentation-proof windows. Aside from this, the system consists of an ammunition resupply vehicle, a support vehicle, BONUS〔http://www.baesystems.com/BAEProd/groups/public/documents/bae_publication/bae_pdf_bonus.pdf〕 and the M982 Excalibur guided projectile. ==Development== The project began its life in 1995 as earlier studies for a self-propelled system based on the FH 77. Further test systems received the designation FH 77BD and FH 77BW. By 2004, two prototypes had been ordered based on a lengthened version of the FH 77B mounted on a modified Volvo Construction Equipment A30D dump truck (6×6 Volvo chassis). In 2008, Sweden ordered a first batch of seven units, while Norway ordered one.〔(Kuriren Klartecken för Archer )〕〔 〕 In August 2009, Norway and Sweden ordered 24 Archers each, in a cooperative deal. The Howitzer was developed for the Swedish armed forces following a contract awarded to Bofors (now BAE Systems Bofors) in 2003 by Försvarets Materielverk (FMV), the Swedish defence acquisition agency to build two demonstrator howitzers. The prototype FH77 BW L52 self-propelled howitzers entered firing trials in Sweden in 2005 and 2006. In September 2006, the FMV placed a contract for detailed design work on Archer and, in January 2007, a contract for the next development phase. The Swedish Army has a requirement for 24 systems (two battalions). Following In September 2008, the Swedish government approved the final development and procurement of the Archer artillery system. In November 2008, Sweden and Norway signed a co-operative agreement for the development of the Archer system and, in January 2009, awarded BAE Systems a contract to complete development of the artillery system with the exception of the remote weapon system which is made by Kongsberg Defence & Aerospace. A final prototype is scheduled for completion by September 2009, which is expected to be followed by a contract for 48 systems – 24 for Sweden and 24 for Norway. Archer was planned to enter service in 2011 but was delayed until October 2013. This because of unforeseen technical problems.〔http://www.svd.se/nyheter/inrikes/sverige-star-helt-utan-artilleri_8272024.svd〕 The Swedish Army received its first four pre-serial production FH-77 BW L52 Archer systems on 23 September 2013.〔(Swedish army has received first pre-serial production of Archer 155mm 6x6 self-propelled howitzer ) - Armyrecognition.com, 23 September 2013〕〔(Sweden Takes Delivery of First Four Archer Artillery Systems ) - Deagel.com, 26 September 2013〕 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「Archer Artillery System」の詳細全文を読む スポンサード リンク
