The US Army and the US Marine Corps have successfully completed limited-user testing (LUT) on Oshkosh Defense's light-combat tactical all-terrain vehicle (L-ATV).
Oshkosh is offering the vehicle as part of the joint light tactical vehicle (JLTV) programme.
Undertaken as part of the JLTV engineering and manufacturing development (EMD) contract, the testing focused on the JLTV system capabilities, functions, operations and interfaces, in a range of simulated tactical environments.
Oshkosh Corporation executive vice-president and Oshkosh Defense president US Army major general (retired) John Urias said: "Our completion of the limited-user testing milestone reinforces Oshkosh's proven ability to design and build vehicles based on decades of experience and a true appreciation for those who will ultimately operate the JLTV.
"Our JLTV solution draws upon real-world experience, gained from supporting the ground operations that our soldiers and marines perform every day."
The LUT also covered operator and crew-level preventive maintenance for the entire JLTV system, ensuring that operators could proficiently and safely operate the vehicle during test and evaluation.
Conducted in September and October, the army-user testing included four tests, three of which were held as 96-hour cycles that were meant to simulate operational missions. The other involved a live-fire demonstration.
US marines completed two test cycles in October and November, including a live fire demonstration.
Oshkosh provided 40-hour new equipment training courses to soldiers and marines operating the JLTVs before the start of their respective testing sessions.
To ensure mission readiness, the company refurbished its testing vehicles for the two LUT phases.
As part of a $56.4m JLTV EMD contract, awarded by the US Army in August 2012, Oshkosh has developed and delivered 22 JLTV prototypes.
Manufactured on the company's active manufacturing line, the JLTV prototypes include a four-door multipurpose variant and two-door utility variant.
Both versions feature common crew protection and advanced automotive systems, as well as the patented Oshkosh TAK-4i intelligent independent suspension system.
The JLTV programme seeks to replace the US Army and Marine Corps' fleet of ageing high-mobility multipurpose wheeled vehicles, and also involves Lockheed Martin and AM General.
