United States Naval Gunfire Support debate

The United States naval gunfire support debate is an ongoing debate among the United States Navy, Marine Corps, Congress, and independent groups like the United States Naval Gunfire Support Association over what role naval gunfire support and naval surface fire support (NSFS) should play within the navy and how such a role can best be provided. At the heart of the issue is the role that naval gunfire support—the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range—should play in the U.S. Navy of the 21st century.

Although the debate at large traces its roots back to the end of World War II, the current debate began in 1992 with the retirement of the last active Iowa-class battleship, USS Missouri (BB-63), as a result of the reduced demand for naval artillery, the rise of ship and submarine-launched missiles and aircraft-launched precision guided munitions (such as laser-guided bombs, which can accurately strike and destroy an enemy target with a single strike). The most striking point of the debate in the United States centers on battleships: owing to the longtime maintenance and upkeep that the four completed Iowa-class battleships have undergone during their time in the navy's active and mothball fleets, many still view battleships as viable solutions for gunfire support, and these members have questioned if the navy can adequately replace the gunfire support provided by a battleship's main guns with the smaller guns on its current fleet of cruisers and destroyers.

The debate has played out across a wide spectrum of media, including newspapers, magazines, web blogs, and congressional research arms like the Government Accountability Office. Each side has presented different arguments on the best approach to the problem, but most of the participants favor the continuation of the DD(X) program or the reinstatement of the Iowa-class battleships to the Naval Vessel Register. The Iowa-class battleships, the Arleigh Burke-class destroyers, and Zumwalt-class destroyers have entered the debate as options put forward for naval gunfire support, while others advocate the use of specifically designed close air support planes and newer missile systems that can loiter in an area as a replacement for naval gunfire.
