This is why the Army is replacing the Hummer

The famous HMMWV's days are numbered. The Army has made its fifth order for the new Joint Light Tactical Vehicle, officially coming in four versions: the M1278 Heavy Guns Carrier, the M1279 Utility, the M1280 General Purpose, and the M1281 Close Combat Weapons Carrier.


According to a release by OshKosh Defense, this order consists of 748 vehicles and over 2,350 installed kits. The vehicle is currently in Low-Rate Initial Production, and the first units are expected to be equipped with the vehicle by the middle of Fiscal Year 2019,with a planned Initial Operating Capability by the end of 2020.

The HMMWV has served for over 30 years, but like the Jeep it replaced in the 1980s, it was proving to be incapable of meeting the demands of a modern battlefield. For the Jeep, the problem was keeping up with armored fighting vehicles like the M1 Abrams tank and the M2/M3 Bradley Fighting Vehicle.

During the War on Terror, the HMMWV proved it could keep up with vehicles, but it was also very vulnerable to a favored tactics of insurgents in Iraq and Afghanistan: the improvised explosive device. Up-armored HMMWVs were developed, but they still proved vulnerable and eventually the military bought Mine-Resistant Ambush-Protected vehicles, including the M-ATV from OshKosh, for use on many missions in Iraq and Afghanistan.

OshKosh notes that the JLTV is 33 percent smaller and 33 percent lighter than the M-ATV. The company stated that the program remains on time and "on budget" in the release. A decision on full-rate production is reportedly pending.

It will still take a long time for the JLTV to replace the HMMWV: Over 281,000 Humvees have been built since it entered service in 1985. This order represents less than one half of one percent of the total Humvee built.
