The BMD-4 (Russian: "Боевая Машина Десанта-4"; ''Boyevaya Mashina Desanta-4'' literally "Combat Vehicle of the Airborne") is an amphibious infantry fighting vehicle (IFV) originating from post-Cold War Russia.〔(【引用サイトリンク】url=http://www.armyrecognition.com/russia_russian_army_light_armoured_vehicle_uk/bmd-4_bmd-3m_bakhcha_airborne_infantry_combat_armoured_vehicle_technical_data_sheet_information_uk.html )〕〔(【引用サイトリンク】url=http://www.globalsecurity.org/military/world/russia/bmd-4.htm )〕 Originally designated as the BMD-3M, the chassis of the BMD-4 is the same as that of the BMD-3, because it was developed on the same basis. This armored fighting vehicle is one of the lightest and one of the most heavily armed in its class, possessing a substantial amount of firepower in comparison to its counterparts. The vehicle was designed to transport Russian Airborne Troops (VDV); increasing its mobility, armament, and protection on the battlefield.〔 Many components of the vehicle, such as the ergonomics and positioning of the passengers, remain relatively unchanged. Primary differences between the BMD-4 and its predecessors lie in its armament. The vehicle is fitted with the Bakhcha-U turret which consists of: a 100 mm 2A70 low-pressure rifled gun, a 30 mm 2A72 coaxial autocannon, and a 7.62 mm PKT coaxial machine gun. The 2A70 rifled cannon is capable of firing high explosive fragmentation rounds and laser guided anti-tank missiles. It also features secondary weapons designed to engage and destroy enemy infantry and armored fighting vehicles. The automated fire control system of the vehicle is advanced with new features that simplify the use of the vehicle's armament by the gunner and commander.〔(【引用サイトリンク】url=http://www.kbptula.ru/en/productions/armament-for-light-and-hard-armour/bakhcha )〕 The vehicle is designed by the Volgograd tractor factory and the armament was developed by the KBP Instrument Design Bureau unitary enterprise located in Tula. Kurganmashzavod is the official manufacturer of the vehicle. The only operator of the BMD-4 is Russia where it entered service in late 2004 and has been produced ever since then. In 2008, a modernized version, designated as the BMD-4M, was introduced with significant contributions from Kurganmashzavod; the designer of the BMP. ==Production== The BMD-4 was adopted by the Russian Armed Forces on December 31, 2004. In August 2005, the 106th Guards Airborne Division received the first batch of these vehicles with a total of 60 vehicles being produced. In 2010, all further purchases of the BMD-4 with the "Bakhcha-U" turret were cancelled along with the 2S25. It was later noted by Colonel Gennady Anashkin that the BMD-4 will still enter service due to the vehicle being a completely new generation essential for the VDV. VDV commander Vladimir Shamanov told in an interview that the original BMD-4 possessed an unreliable base while the modernized BMD-4M is more than satisfying for the Russian airborne troops. On March 21, 2008, Kurganmashzavod unveiled a modernized variant of the vehicle and was designated as the BMD-4M. The primary cause of the alterations was due to the bankruptcy of the original manufacturer being the Volgograd tractor factory. In 2008 it is planned to carry out comprehensive testing modernized BMD-4 program agreed with the Chief Armor Management (Bolshoi) of the Ministry of Defense and the VDV. According to test results and Mikhail Bolotin, the president of Concern Tractor Plants (KTZ), mass production was initially planned for the following year. The mass production of the modernized BMD-4 was later postponed along with the 2S25 Sprut-SD. Nikolay Makarov, the Chief of the General Staff of Russian Armed Forces, dismissed the BMD-4 as "a version of the BMP-3" with no protection and costs more than an expensive tank. In August 2012, Alexander Sukhorukov, who was then deputy Defense Minister, said that the armored vehicle BMD-4M does not meet the requirements put forward by the Russian military department, and will not be purchased.〔 At the same time a week before, Vladimir Shamanov said the BMD-4M is fully compliant with the VDV, which was more important in this regard than the requirements of the Ministry of Defence. He stressed that the fate of the BMD-4M is decided by the supreme commander Vladimir Putin.〔(【引用サイトリンク】url=http://www.militaryparitet.com/ttp/data/ic_ttp/2581/ )〕 The Russian Army received another prototype batch of the modernised BMD-4M airborne assault vehicle during mid-2014. Eight modernized BMD-4M vehicles were delivered to the 106th Guards Airborne Assault Division by Kurganmashzavod, where the vehicles continued to undergo testing.〔 "The vehicles proved themselves as technology of the future: they roved in differing climatic conditions, airdropped, tested in water, including being redeployed at sea. All of this was noted by the commission, which recommended to supply the VDV (the vehicles ) this year as a result of testing," Maj. Gen. Andrei Kholzakov, deputy commander of VDV, said on January 15, 2015. Kholzakov added that the decision of the state commission came as field tests of BMD-4M airborne fighting vehicles and BTR-MD Rakushka armored personnel carriers concluded successfully in 2014.〔http://sputniknews.com/military/20150115/1016945481.html〕 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「BMD-4」の詳細全文を読む スポンサード リンク
