Oshkosh L-ATV

The Joint Light Tactical Vehicle (JLTV) was a program to find a replacement for the Humvee with the primary aim of the design to improve on areas where the original Humvee fell short.  The JLTV was in development for several years with a number of military contractors submitting bids to the program.
After several years of development, evaluation and tests in various proving grounds by the Army and Marines the Oshkosh Light Combat Tactical All-Terrain Vehicle (L-ATV) was selected on 25 August 2015.

While the Humvee is a very capable vehicle able to tackle a wide variety of off-road situations, it initially lacked protection to the occupants from machine gun fire, shrapnel and improvised explosive devices (IEDs).
JLTV program was to incorporate lessons learned from using the Humvee in combat situations while balancing payload, mobility and protection into a new vehicle.  The new vehicle must be able to be delivered via C-130 or CH-47/CH-53 helicopters.
The Army requirements is to buy close to 50,000 vehicles in the next 25 years and the Marine Corps another 5,500.  A production contract is to be awarded to a single vendor with each vehicle coming off the assembly line not exceeding $250,000.
