5 Experimental Warships That Changed Naval Warfare Forever

Dreadnought reset the global battleship race. Pre-dreadnoughts (Dreadnought gave her name to both the old and the new generations of battleship) immediately became second-class ships. Traditional naval powers quickly invested huge resources in the construction of dreadnought fleets, and smaller powers soon followed suit. Dreadnought herself served until 1918, drawing blood only once, when she rammed and sank a German U-boat.

Just a few months back, the U.S. Navy began a great experiment: The USS Zumwalt.

The first of a probable three ships, Zumwalt once represented the future of U.S. naval surface warfare. Budget shortfalls, changed priorities and predictable cost overruns cut the projected purchase from a fleet-sustaining thirty-two units to an experimental trio of ships.

Still, Zumwalt represents a technological marvel, including an array of innovations that set her apart from every other ship in the U.S. Navy, and indeed the world. Her value as an experimental test bed for new concepts, architectures and technologies may, over time, exceed her value as a military unit. In this she joins a long tradition of experimental warships, vessels that often had more impact as technological marvels than as useful ships of war. Here are the five most important experimental vessels of the modern seafaring age:

Is It Time to Bring Back the Battleships?

HMS Dreadnought

In 1905, the Royal Navy laid down HMS Dreadnought, the world’s first all-big-gun ship. American and Japanese engineers had explored the potential of such ships, but neither dove into construction with the enthusiasm of First Sea Lord Jackie Fisher. Dreadnought came about through the combination of a series of architectural innovations, including improved fire control and superior propulsion. When she entered service, Dreadnought immediately became the world’s most powerful battleship, faster and more heavily armed than any contemporary.

Are Submarines Almost Obsolete?

USS Monitor

USS Monitor was not the first ironclad warship, or even the first to have an entirely iron hull. However, she included so many technological innovations that she richly merits inclusion of this list. The impetus for construction of Monitor was a report that the navy of the Confederate States was converting an older, wooden warship into an ironclad in order to break the blockade of Hampton Roads.

With a single turret sitting atop a long metal raft, Monitor looked like no other warship of the time (or since). However, when she reached Hampton Roads she managed to turn back CSS Virginia (which had previously wreaked havoc on the wooden ships blockading the port) in the first clash of ironclads. Monitor patrolled the area until advancing Union troops forced the scuttling of Virginia. Several months later, she sank in a storm en route to North Carolina. By that time, the U.S. Navy had built several more examples of the type, even as France and the United Kingdom had begun serious investment in armored cruisers.

Could America Beat Russia and China in a Naval War?

HMS Furious

HMS Furious holds the distinction of being at the center of two experiments; the first failed, the second successful. In the early days of World War I, First Sea Lord Jackie Fisher sought specialized warships for the “Baltic Project,” a half-baked plan to invade Germany’s Baltic coastline. Debate endures regarding how seriously Fisher pursued this project, but his advocacy resulted in HMS Furious and two sisters. Furious, termed a “light cruiser,” displaced 20,000 tons, and was intended to carry two 18-inch guns; larger than any battleship gun at the time.

The experiment didn’t last long, as the Royal Navy had little need for another battle cruiser after Jutland. However, Furious provided a useful hull for testing another concept; a dedicated aircraft-carrying vessel that could launch and recover conventional aircraft. Furious underwent partial conversion during the war, and full conversion after. The first real aircraft carrier, she served with distinction in World War II, and set the terms for a revolution in naval warfare.
