Task Force 63 is the Logistics Force. Task Force 63 and Military Sealift Command’s Sealift Logistics Command (SEALOGEUR) are two separately named formations that actually operate as a unified one with one staff. Task Force 63 is headquartered at Naples, Italy. Composed of oilers, provision ships, and repair ships, its mission is the delivery of supplies at sea, and effecting repairs to other ships and equipment of the Fleet. Commander, Task Force 63 (CTF-63) is the operational commander of all the U.S. 6th Fleet air and sea logistics. While in theater, Military Sealift Command’s Naval Fleet Auxiliary Force and Special Mission ships report to CTF-63 along with cargo planes that support 6th Fleet and U.S. European Command logistics missions.

CTF-63 is also responsible for ordering and tracking spare parts and supplies being delivered to ships in theater. CTF-63 is the immediate operational commander of Maritime Prepositioning Ship Squadron One (MPSRON ONE) based in the Mediterranean Sea. The ships of MPSRON One are deployed year-round. This pre-positions U.S. military cargo at sea. Should a military or humanitarian crisis arise in theater, the squadron can deliver its cargo ashore, enabling a faster U.S. response.
