The little cruiser with a battleship’s guns

It first entered Navy service in February, 1895, with some doubters mocking its excessive armament while Americans hoped that its speed, steel, and guns would allow it to survive while outnumbered if under heavy attack. Instead, the small but mighty USS Olympia slaughtered an enemy fleet, bombarded shores, and escorted convoys during its 27-year career.

In the late 1800s, the U.S. Navy wrestled with what the service should do and what ships it needed for the 1900s. The battle of the Merrimack and Monitor decisively proved that wooden ships were on their way out, but the rise of steel ships showed that the iron vessels made in earnest during and after the Civil War wouldn't survive either.

Meanwhile, sails were the efficient and cheap method of propelling a ship, but it was clear that steam gave commanders more flexibility and more options in combat.

And the Navy needed ships to secure American shores even as a constrained budgets made ship-building tough. Some presidents were already looking at using the Navy for power projection as well.

So, the Navy had to decide whether it should have lots of cheap ships, lots of coastal defenses, steam or sail power, all while keeping power projection a feasible option.

The Navy figured out a plan address all the changes and requirements: A new fleet of steel vessels that relied on steam power but still had masts for sails for long voyages when the winds were favorable. Because the U.S. couldn't spend as much on ship hulls as potential European attackers, each ship would be heavily armed and as fast as possible.

This resulted in cruisers that could hopefully run ahead of enemy fleets, pelting the lead of the enemy ship with shot after shot while staying out of range of the rest of the enemy fleet. (Video game players do this today against powerful enemies and call it, "kiting.")

A jewel of this new fleet was C-6, an armored cruiser scheduled to first float in 1892 and commission a few years later. This ship would become the USS Olympia, named for the capital of America's newest state at the time, Washington.

The Olympia fit all the qualifications of the new naval plan. It could steam at over 21 knots while most of its potential enemies topped out at 18. It had four 8-inch guns, two in a single turret forward and two in a turret aft. These big guns were the primary armament, but the ship also had ten 5-inch guns. A few years after launch, it also got Gatling guns and sidearms for potential boarding parties.

Some naval observers around the world critiqued the design, saying that it was either an overarmed cruiser or a too-tiny battleship. But these heavily armed cruisers were designed for their own mission, and they could outrun attackers while picking them off with their larger guns.

The defensive war Olympia was ostensibly designed for never came, though. Instead, it was sent to the Pacific where it became the flagship of Commodore George Dewey before the USS Maine, a larger and even better armed ship, blew up in Havana Harbor. While the explosion was later found to have likely been caused by an ammo handling accident or an overheated bulkhead that touched gunpowder stores, the U.S. blamed it on a Spanish attack at the time.

In response to the Maine's destruction, Dewey and his squadron were sent to Manila Bay to attack the Spanish fleet there. The hope was that the ships, protected by steel and heavily armed, could rush past the guns of the Spanish coastal defenses and engage the Spanish fleet with the large guns.

Dewey sent his fleet towards the bay in two columns steaming behind the USS Olympia. Dewey was holding his fire until sunlight and reconnaissance revealed the enemy fleet, even though this allowed shore gunners to try to spot and hit the American ships in the darkness. A sudden fire on the revenue cutter exposed it, and a cruiser and the cutter were forced to return fire.

But the rest of the fleet held its fire until Dewey saw the fleet, crept in range, and got the angles right. Spanish rounds were raining against the steel hulls of the American ships, and gunners crouched behind the paltry armor and prayed for safety until Dewey, on the Olympia, calmly told the ship's captain, "You may fire when ready, Mr. Gridley."

The American fleet opened up and slaughtered the decrepit Spanish fleet, sinking all vessels and capturing the port in mere hours. America now owned the capital of the Philippines and would get the islands in the peace treaty that came later. Nine Americans had been wounded while the fleet had killed 161 Spanish fighters and wounded 210.

The Olympia and Dewey became famous, and the ship went on to serve in World War I as a convoy escort. And, in 1918, Olympia bombarded the shore during an amphibious assault at Murmansk in the Russian Civil War.

But the era of the Dreadnought had come, and in the years following World War I, it became clear that the Olympia was no longer enough ship to compete with enemy combatants. And America, flush with prestige after World War I and possessing overseas colonies from the Spanish-American War, had the money to build a larger, more powerful fleet.

In 1922, Olympia was decommissioned, and the hull was slated for the scrap heap, but activists pushed for the ship to be turned into a museum. It took decades of wrangling before Philadelphia donors got the money to return Olympia to the 1898 configuration and moored the ship in the city's waterfront in 1958.

Since then, the ship has hosted visitors who wanted to walk the weathered boards of its deck or see the steam engines that made its speed possible. The Flagship Olympia Foundation is trying to raise the money necessary to dry dock and overhaul the ship. It's already been on the water since 1892, and could have decades more in it after repairs.
