The Port of Mobile became the economic genie that pulled Alabama out of the Second Great Depression. It was successful in doing so because it maintained its own security, both on land and on the open water. Its early waterborne security was primarily composed of armed tugboats, but their yard facilities refurbished, converted, or built numerous other armed escort and security craft during and after the emergency. Most of their craft were only good for the Gulf of Mexico, but they built true ocean-going escort craft in time. They never built warships, you understand. Only nations need warships. The corporations of Mobile built armed escorts to protect Alabama-flagged shipping and other port facilities throughout the Americas and all over the world in time. Never warships.
