1. SCOPE.

This statement of work (SOW) defines the effort required for the design, construction, testing, and deliverycharter of the auxiliary dry cargo ships (T-ADC(X)). The work is divided into twohree phases: engineering design, and detail design and construction, and charter. It includes the associated program management, design, construction, testing, and delivery, and charter requirements.

 

The T-ADC(X) program has been initiated to design, construct, and delivercharter auxiliary dry cargo ships that fulfill the requirements of the T-ADC(X) operational requirements document of (TBDdate). The ships replace the current logistics lift capability of the T-AE 26, T-AFS 1, and T-AFS 8 Class ships.
