Joint Light Tactical Vehicle (JLTV) program

[Hicks]

La proposta di AM General\General Dynamics Land Systems per il programma JLTV, il GTV(General Tactical Vehicle), è già in fase di test. La differenza tra M-ATV e il JLTV sta nel peso e nella versalità: il secondo più "leggero" può essere trasportato per via aerea CH-53K mentre il primo no. Oltre alla maggiore mobilità farà da piattaforma a tutte quelle versioni che l'HW ha ricoperto in questi anni.

L' M-ATV è stato pensato per missioni di pattugliamento, scorta ma soprattutto richiesto urgentemente per l'Afghanistan. L'equipaggio dell'M-ATV è di 4 posti mentre l' JLTV dovrebbe arrivare ad ospitare 6 operatori. In sostanza il JLTV è la vera evoluzione dell'HUMVEE.

 

 

The 27 April 2010, The General Tactical Vehicles (GTV) team of General Dynamics Land Systems and AM General delivered today seven Joint Light Tactical Vehicles (JLTVs), four trailers and supporting equipment ahead of schedule to the U.S. Army and U.S. Marine Corps for Technology Development (TD) phase testing. The TD phase includes a 12-month test and evaluation process at Aberdeen Proving Grounds, in Aberdeen, Md., and at the Yuma Proving Grounds in Yuma, Ariz. This follows GTV’s previous ahead-of-schedule deliveries of armor samples, ballistic hulls and spare parts.

In January 2009, Australia entered into a Land Force Capability Modernization Project Arrangement for the TD phase of the JLTV program, enabling tactical vehicle interoperability and integration between U.S. and Australian forces.

Armament

On this time, there is not specific armament mounted to the vehicle, but in the future the vehicle can be fitted with a 12,7 mm or 7,62 mm machine gun for his self-protection.

Protection

The JLTV design will include a basic armor protection package as well as provisions to accommodate an additional add-on armor kit. General Tactical Vehicles will locate in the Detroit metropolitan area to leverage the best of American automotive technology and military research and development to deliver the JLTV. General Tactical Vehicles applies proven technologies along with a modular design that will accommodate continuing advances in armor and vehicle systems. The innovative GTV JLTV design features a robust light-weight hybrid hull, semi-active suspension system, digital cockpit, and over 95 percent common components across the entire JLTV family of vehicles.

Propulsion

GTV’s offer for the JLTV maximizes survivability and optimizes power and payload. The approach focuses on commonality of systems and components along with modular armor, resulting in an innovative and agile vehicle system that will provide enhanced crew protection, increased cargo capacity and transportability. The JLTV General Dynamics is equipped with parallel arm adjustable height suspension to give the vehicle increased mine blast protection without jeopardizing air and sea transportability. The JLTV is motorized with a proven propulsion systems with a high horsepower-to-weight ratio to maximize payload, plus a driveline that gives the vehicle tough off-road capabilities.

Variants

The JLTV family of vehicles will comprise five “Mission Role” variants: the Combat Tactical Variant, the Command and Control Variant, the Utility Variant, the Light Infantry Squad Carrier Variant and the Reconnaissance Variant. The vehicle family will also include compatible trailers. Key deliverables under the JLTV TD contract include seven vehicles and four trailers representing the three mission role variants (infantry, general purpose, utility) comprising the JLTV Family of Vehicles; designs for each of 10 sub-configurations; and ballistic hulls and sample armor components for government testing.

premetto che mi limito a osservazioni da uomo di strada (appassionato); in effetti sembra parecchio "leggero", tanto più per i nuovi scenari (per non parlare dell'A-stan stesso).

da 1.7t a 2.3t a seconda delle versioni è neppure lo scafo a V. I nuovi veicoli (altri stati) considerati "leggeri" son ben più protetti muovendosi in tutt'altra direzione; gli stessi Lince sono i "leggeri" presenti e futuri di vari stati e partono da ben altri requisiti.... certo i kit di protezione aggiuntivi possono fare qcs...

Il sito ufficiale del mezzo conferma la presenza dello scafo a V per la protezione dalle mine e IED. Ho scordato di riportarlo nel primo post, scusate.

 

Drawing from the combined experience of General Dynamics and AM General in building and supporting tactical and combat vehicles, GTV’s vehicle design provides an armored crew capsule with an optimized V-shaped hull for protection against mines and IEDs, a state-of-the art C4 architecture that accommodates future force technology capabilities, high-performance and off-road mobility and deployability by land, sea and air.

La differenza di peso tra l'M-ATV e il JLTV è di 5-5,5 tonnellate: 14 tonnellate per il primo e 9 per il secondo. Il Lince si attesta sulle 7 tonnellate. Direi quindi che il programma JLTV è in linea almeno con il nostro Lince.

A che punto si trova il programma? Il Senato ha proposto di cancellarlo, in quanto i requisiti sono stati cambiati molto spesso oltre all'aumento dei costi. C'è qualche possibilità che prosegua o verrà definitivamente cancellato?

The Joint Light Tactical Vehicle (JLTV) is being developed by the Army and the Marine Corps as a successor to the High Mobility, Multi-Wheeled Vehicle (HMMWV) that has been in service since 1985. On October 28, 2008, awards were made for the JLTV Technology Development (TD) Phase to three industry teams: (1) BAE Systems, (2) the team of Lockheed Martin and General Tactical Vehicle, and (3) AM General and General Dynamics Land Systems. Once testing was completed and technology requirements established, a full and open competition was expected to be conducted in the late summer of 2011 for the Engineering and Manufacturing Development (EMD) Phase; the Department of Defense (DOD) planned to award two contracts for the EMD phase, which was scheduled to last 24 months.
In February 2011, it was announced the award of the EMD contract would be delayed until January or February 2012 because the Army changed requirements for the JLTV. DOD had planned to award two contracts for the EMD phase, which was scheduled to last 24 months, but instead proposed a 48-month-long EMD. There will be two JLTV variants—a Combat Tactical Vehicle (CTV) that can transport four passengers and carry 3,500 pounds and a Combat Support Vehicle (CSV) that can transport two passengers and carry 5,100 pounds.
On January 26, 2012, the Army issued the Request for Proposal (RFP) for the JLTV’s EMD phase. Up to three EMD contracts could be awarded, and contract award was scheduled for June 2012. The EMD phase was planned to last 27 months, and vendors would be required to provide 22 prototypes for testing 12 months after contract award. The target cost for the base vehicle is $250,000 excluding add-on armor and other kits.
On August 22, 2012, the Army announced the award of three firm-fixed price JLTV EMD contracts totaling approximately $185 million. The three companies awarded the EMD contracts were AM General, LLC (South Bend, IN); Lockheed Martin Corporation (Grand Prairie, TX); and Oshkosh Corporation (Oshkosh, WI). Australia is reportedly “not committed” to participating in the EMD phase, and the new RFP has no Australia-specific requirements—such as right-hand drive. Furthermore, the Australian Ministry of Defense (MOD) is said to be looking at a domestic variant of the JLTV, although they stated that they would continue to monitor the JLTV program.
The FY2013 Budget Request for JLTVs is $72.3 million for Army Research, Development, Test and Evaluation (RDT&E) and $44.5 million for Marine Corps RDT&E, for a program total of $116.8 million. The House and Senate Armed Services Committees as well as the House Appropriations Committee have recommended fully funding the Administration’s FY2013 JLTV Budget Request. The Senate Appropriations Committee recommended cutting $5.9 million from the FY2013 Budget Request due to a two-month contract award delay.

Potential issues for Congress include clarification of foreign participation in the JLTV program, given Australia’s apparent non-participation, and how the Army’s upcoming study to revise overall tactical wheeled vehicle requirements might affect the JLTV program. Reported possible JLTV budget shortfalls starting in FY2015 might also be of congressional concern. This report
will be updated.
