Oshkosh Defense has been awarded a sole source contract with the Defense Logistics Agency (DLA) to provide replacement parts for medium and heavy tactical vehicles. This annual contract has a potential duration of 10 years, if all option years are exercised, and a value of up to $1.12 billion. This follows a one-year contract that included seven option years, each of which were exercised, that ended in December 2008. Under the contract, Oshkosh Defense will supply the DLA with replacement parts to support Oshkosh's medium and heavy tactical vehicles, which include the Medium Tactical Vehicle Replacement, Heavy Expanded Mobility Tactical Truck, and Palletized Load System. Oshkosh also supplies replacement parts for other manufacturers' medium- and heavy-payload vehicles.
