Mobile offshore base
Mobile offshore base (MOB), sometimes called a joint mobile offshore base (JMOB), is a concept for supporting military operations beyond the home shores, where conventional land bases are not available, by deploying on the high seas or in coastal waters, in-theater multipurpose floating base assembled from individual platforms. In essence, a MOB is a multipurpose modular self-propelled floating platform, or several interconnected platforms, that can perform multiple functions of a sea base including strike, deployment and logistics.
