These "sea bases" offer a host of benefits over terrestrial bases. They're easier to defend, can be deployed anywhere in the ocean, and are expected to save the US taxpayers quite a bit of money over the long term. Part of that savings comes from the military's flexibility in their construction. While a traditional naval command ship for example costs billions of dollars and decades to construct, the Navy has no qualms about renting cargo ships and converting them into short term warfighters, as Military Sealift Command (MSC) did with the M/V Cragside, a top secret Maritime Support Vessel (MSV) that can deliver our Special Forces anywhere in the world.
