Contractor Logistics Support (CLS) is when a contractor, rather than the government, is responsible for the integration of logistics support functions such as providing engineering support, identifying requirements for spare and repair parts, facilities, materiel, equipment, personnel, and performing maintenance on weapon systems. CLS is a method of obtaining support for a product throughout its life cycle. Contractors can provide logistics support over a wide range of options, from Interim Contractor Logistics Support (ICLS) covering the initial fielding while the product support package is being deployed, to supporting specific limited operations, to full contractor support. CLS may be utilized as appropriate for all of the requisite logistics support for specific logistics functions. [1, 2]

CLS includes the burdened cost of contract labor, material, and assets used in providing support to a weapon system, subsystem, and associated support equipment. CLS funding can cover depot maintenance and, as negotiated with the operating command, necessary organizational and intermediate maintenance activities. If CLS is selected as the primary means of support, all functional areas included in the CLS cost should be identified. [1]
