The Lockheed Martin JLTV (Joint Light Tactical Vehicle) is a prototype armor-capable vehicle that was one of six original competitors for a Joint Light Tactical Vehicle that will replace the Humvee.〔http://defensetech.org/2010/06/04/first-look-joint-light-tactical-vehicle-jltv/〕 The JLTV goal was to provide a family of vehicles able to perform multiple missions protected, sustained and networked mobility for personnel and payload over a full range of operations.〔http://www.lockheedmartin.com/us/products/jltv.html〕 Lockheed's JLTV design lost out to the Oshkosh L-ATV in August 2015.〔(Oshkosh Wins JLTV Award ) – Armytimes.com, 25 August 2015〕 On 9 September it was announced Lockheed Martin would protest this decision.〔(【引用サイトリンク】title=Lockheed Martin Protests JLTV contract award to Oshkosh )〕 ==Design== The Lockheed JLTV vehicles were powered by a Cummins diesel engine coupled to an Allison Transmission. The engine was the primary source of electrical and could provide external power for dismounted users.〔〔(Lockheed JLTV ) - Army-Technology.com〕 It could sustain top speeds exceeding , ford of salt or fresh water, and had a gross weight of .〔(3D camo pattern, new wheels, armor on tap ) - Armytimes.com, 14 November 2010〕 The four-cylinder engine had a fuel efficiency of as much as 14 miles per gallon, better than some SUVs. The system did not have an alternator, but instead used an in-line power generator capable of producing 24 kW of electricity, which could be scaled up to as much as 75 kW.〔(Army to Start Next JLTV Competition This Fall ) - DoDBuzz.com, 25 September 2014〕 In August 2012, Meritor Inc. announced they would be integrating their ProTec High Mobility Independent Suspension (HMIS) into the Lockheed JLTV in response to its moving on to the EMD phase of testing. Meritor designed the ProTec Series 30 HMIS to provide enhanced off-road maneuverability and ride quality. Meritor asserted that the system underwent thorough testing, totaling over 100,000 miles of travel.〔(Meritor Defense Supports Lockheed Martin with Protec Suspension for JLTV Development Contract ) - Prnewswire.com, August 27, 2012〕 The independent air suspension offered of travel and greatly reduced crew fatigue through a smoother ride over terrain.〔 The vehicle had an improved V-hull to protect from underbody blasts. It had standard armor protection and could accommodate add-on armor kits. In October 2011, Lockheed announced their JLTV met standards for IED-protected vehicles in government blast tests, providing the level of protection with 40 percent less weight than currently deployed all-terrain mine-protected vehicles.〔〔 Its underbody used a modified V-hull called a "cursive W"-shaped hull that was effective in dissipating blasts forward, aft, and out to the sides.〔 The internal cab had been designed similar to that of a cockpit to make use of all available space. It was made to be ergonomic with capabilities integrated into the dashboard to free up space for the operators to be able to perform their missions. All vehicle variants were the same from the driver's seat forward.〔 The base vehicle had no specific armament configuration, but could be fitted with a 7.62 mm or 12.7 mm machine gun.〔〔 Lockheed and Moog Inc. joined to develop the Common Hellfire Package (CHP) to enable the firing of AGM-114 Hellfire missiles from various platforms. The CHP has been test fired from a stationary trailer-mounted pedestal that could be towed behind the Lockheed JLTV. The vehicle also fired Direct Attack Guided Rockets from a pedestal launcher mounted in the bed. The JLTV's ability to integrate these systems would provide troops greater firepower, with the intent being to reduce the need to call for aviation support.〔(Lockheed, Moog Develop JLTV-Towed Hellfire Launcher ) - Defensenews.com, 22 October 2013〕 Vehicles for the EMD phase were manufactured at BAE Systems' facility in Sealy, Texas. On 16 October 2013, Lockheed announced production would be moved to their assembly line in Camden, Arkansas. The new manufacturing complex was expected to give better production efficiency and cost reductions. BAE remained a partner on the Lockheed Martin JLTV team, providing integrated cabs, protection solutions, and vehicle manufacturing expertise.〔(Lockheed Martin to build Joint Light Tactical Vehicle at Award-Winning facility in Camden, Arkansas ) - Armyrecognition.com, 16 October 2013〕 BAE's Sealy facility was shut down by June 2014.〔(BAE Shutters Texas Factory, JLTV Production Moved ) - Defensenews.com, 15 October 2013〕 The Lockheed JLTV passed the government’s Manufacturing Readiness Assessment (MRA) from 18-19 November 2013, allowing it to be manufactured at the Camden facility.〔(Lockheed Martin JLTV vehicle successfully completes U.S. Manufacturing Readiness Assessment ) - Armyrecognition.com, 12 December 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「Lockheed Martin JLTV」の詳細全文を読む スポンサード リンク
