The order was issued under the US Army's existing Family of Heavy Tactical Vehicles (FHTV) contract.
Production will begin in April 2010 and be completed in September 2011.
The PLS A1 is the next generation of the PLS, which Oshkosh has manufactured for the US Army's distribution and resupply needs for its most challenging military missions.
The vehicle features a Long Term Armor Strategy (LTAS)-compliant cab and a 600-hp engine.
It also uses the Oshkosh-patented TAK-4(r) independent front suspension for greater off-road mobility.
Additionally, the truck and trailer carry a demountable cargo bed, also known as a flatrack, which features a 16.5-ton payload capacity.
Oshkosh Defense has also received an award valued at more than $33 million from TACOM LCMC to install rear-view camera systems on more than 2,250 MRAP All Terrain Vehicles (M-ATV).
Work under the delivery order is expected to begin in March 2010 and be completed in May 2010.
With this delivery order, a total of 4,400 M-ATVs will be integrated with the camera system.
The camera system, which integrates with existing vehicle video displays, provides excellent rearward visibility under all operating conditions.
The system uses an infrared camera core in an LED-equipped tailgate assembly and provides visibility through dust, obscurants and incremental weather in both day and night operations.
