Naval power has always been a strong arm of any advanced military. Whether used in ship to ship combat or ground support, there has never been any vessel more proven in combat than the battleship.
The United States Navy is (as far as I know) the only navy in the world that has two decomissioned battleships that can be recomissioned into service, and are always maintained to do so. These ships, the USS Missouri and USS Iowa, had recently participated in the 1991 Gulf War, providing support for troops on the ground with their large battery.
In this the Missouri performed remarkably well, firing over 100 rounds and over 40 Tomahawk missles. Her decomissioning has launched a naval debate as to the future of naval-ground support, and the role the battleship plays.
The new class of American destroyers, DD(X) USS Zumwalt, is being designed to replace the battleships as a land bombarding vessel.
Gen. Michael W. Hagee, former commandant of the Marine Corps, said on April 1, 2003, that loss of naval surface fire support from battleships would place his troops "at considerable risk."
The DD(X) has already cost $5.964 billion, as of January, already exceeding the original estimates, by 81%! The first ship will not even be in comission by about 2015.
Keeping the battleships in reserve only costs $250,000 a year, reactivating them $500,000, and modernizing a battleship at about $1.5 billion.
The main argument is in armament. The battleships could fire, with their 18 16-inch guns, 460 projectiles in nine minutes. The Zumwalt can only fire 70 missles, about $1 million a minute. It does include 2 155mm guns, but Marines claim they cannot reach the shore.
Former longtime National Security Council staffer William L. Stearman, now executive director of the U.S. Naval Fire Support Association, "In short, this enormously expensive ship cannot fulfill its primary mission: provide naval surface fire support for the Marine Corps."
Gen. P.X. Kelley, the renowned former commandant, said: "I would hate to see a premature demise of the battleships . . . without a suitable replacement on station. In my personal experience in combat, the battleship is the most effective naval fire support platform in the history of naval warfare."
In short, the battleship is still a reliable tool against surface targets. If we get rid of them now, ultimately, the soldiers in need of the big guns will pay the price.
