Donald Trump is going to make America’s military great again by bolstering our most important strategic advantage: the United States Navy. Here’s how:

Boosting shipbuilding to meet the Navy’s 355-ship goal could require an additional $5 billion to $5.5 billion in annual spending in the Navy’s 30-year projection, according to an estimate by naval analyst Ronald O’Rourke at the Congressional Research Service.

The Navy’s revised Force Structure Assessment calls for adding another 47 ships including an aircraft carrier built in Virginia, 16 large surface warships built in Maine and Mississippi, and 18 attack submarines built in Connecticut, Rhode Island and Virginia. It also calls for more amphibious assault ships, expeditionary transfer docks and support ships.

In addition to being good for national security, a larger fleet would be better for both the sailors, who’d enjoy shorter deployments, and for the ships, which would have more down time for maintenance, said Matthew Paxton, president of the Shipbuilders Council of America, which represents most of the major Navy shipbuilders.

“Russia and China are going to continue to build up their navies,” he said. “The complexities aren’t going to get any easier. The Navy, more than any of the services, is our forward presence. We’re going to need this Navy.”

It’s a welcome move for the President elect. Whether he can do it without the obscene levels of government waste showcased by the government’s F-35 program remains to be seen, but it’s an encouraging start.
