Dravo Corporation Shipyard
Neville Township, Allegheny County, Pennsylvania
Marker Inscription
During World War II, Dravo's shipyard here was a leader in the manufacture of Landing Ship Tanks--LSTs--for the U.S. Navy. Dravo's over 16,000 workers produced a total of 145 LSTs. This and four other inland yards, all using techniques pioneered by Dravo, contributed two-thirds of the Navy's fleet of over 1,000 LSTs. These amphibious craft proved vital to the success of Allied landings on enemy shores, 1943-45.

The Story
On this island in the Ohio River just below Pittsburgh, the Dravo Corporation turned a peacetime engineering firm into one of the arsenal of democracy's most unlikely powerhouses. Its inland shipyard mass-produced Landing Ship Tanks—the ungainly, flat-bottomed LSTs that carried tanks, trucks, and troops straight onto hostile beaches. Using assembly-line techniques Dravo pioneered, this yard and four others hundreds of miles from any ocean built two-thirds of the Navy's entire LST fleet, floating them down the rivers to the sea. More than 16,000 workers here produced 145 of the vessels between 1943 and 1945.
Why it matters
The LST was one of the decisive workhorses of Allied amphibious warfare, from Sicily to Normandy to the Pacific, and Pittsburgh's rivers helped make its mass production possible—proof that America's industrial heartland won battles it never saw.
The story behind this marker
AI contextThe era
During the Second World War, the United States remade itself into what President Roosevelt called the arsenal of democracy, and nowhere was that transformation more complete than in the industrial corridor around Pittsburgh. The rivers that had carried coal and steel for generations now carried something new: warships, built hundreds of miles from any ocean.
The Ohio River, forming just below Pittsburgh, was the artery. Along it, engineering firms that had spent peacetime building bridges, dams, and river craft pivoted almost overnight to military production. Neville Township, on its island in the river, became one of the improbable centers of that effort.
It was an era when the whole country was mobilized, and the home front became a battlefront of its own kind — measured not in territory but in tonnage, in ships launched, in the sheer pace of production that could out-build an enemy.
People & events
Here the Dravo Corporation turned its river-engineering expertise to a single urgent purpose: building Landing Ship Tanks, the vessels the Navy called LSTs. Ungainly, flat-bottomed, and enormous, an LST was designed to run right up onto a hostile beach, drop its bow doors, and disgorge tanks, trucks, and troops directly onto the sand.
Dravo did not just build them — it pioneered the techniques for building them fast. More than 16,000 workers on this site produced 145 of the vessels. Their assembly-line methods were then adopted by four other inland yards, so that together these river shipyards, far from any coast, turned out two-thirds of the Navy's fleet of more than a thousand LSTs.
Each completed ship began an unlikely journey: floated down the inland rivers toward the sea, then out to the theaters of war. The workforce here never saw the beaches their ships would reach, but their labor was stitched into every one of them.
Its place in the American story
The LST was one of the decisive workhorses of Allied amphibious warfare. Between 1943 and 1945, the great landings that turned the war — on hostile shores in Europe and across the Pacific — depended on getting armor and men from ship to beach under fire. The LST is what made that possible at scale.
What happened on this island is a powerful reminder that America's industrial heartland won battles it never saw. The muscle that had built the nation's bridges and river trade was redirected toward the sea, and the same rivers that carried commerce carried the tools of liberation.
It is also a story about ingenuity as much as size. Dravo's pioneering methods, copied across the inland yards, show how a single good idea about how to build faster could ripple outward into a national capacity — the quiet, unglamorous genius of mass production that underwrote the fighting front.
If you visit
Come to see the water first. Standing near the Ohio River below Pittsburgh, you can picture the sheer strangeness of the scene: fully built warships slipping downstream, hundreds of miles from the ocean they were bound for. The geography is the whole point of the story.
Think about the scale as you look around — more than sixteen thousand people working here, and 145 ships launched into a river. This was industry as a civic effort, a community mobilized around a single wartime task.
It fits naturally into a road trip through Pittsburgh's river-and-industry heritage, a counterpoint to the steel and coal history all around it. Bring your imagination: the yard's greatest monuments long ago sailed away to distant beaches, so what you're really visiting is the launching point of an outsized contribution to a war fought an ocean away.

Mooncrest
Carnegie, PA · est. 2004
In 1943, with the nation's factories running full-tilt for the war, the federal government threw up planned housing like Mooncrest to shelter the workers who kept the arsenal fed. Its residents crossed the river to the Dravo Corporation, turning out armor plate, munitions, and ships for the fight overseas. After the war the Air Force ran the community briefly before the little homes passed into private hands in the 1950s.
Pittsburgh Grease Plant
Pittsburgh, PA · est. 2000
Founded in Pittsburgh by Grant McCargo in 1885, this plant became a major producer of the lubricating grease that kept American industry, railroads, and machinery running. Its most storied contribution came during World War II, when it supplied five million pounds of "Eisenhower grease" deemed vital to the war effort. Absorbed into Standard Oil of New Jersey after 1929, the works kept operating until 1999 — more than a century of quiet but essential industrial labor.
Davis Island Lock & Dam
Avalon, PA · est. 1987
In the decades after the Civil War, the U.S. Army Corps of Engineers set out to tame the Ohio River for year-round navigation. Their first lock and dam on the river, built here between 1878 and 1885, was a marvel of its day—the largest movable dam yet constructed, with the world's first rolling lock gate and its widest lock chamber. It served until 1922, when the nearby Emsworth Locks and Dams replaced it.
Michael A. Musmanno (1897-1968)
Stowe Township, PA
This plaque marks the home of Michael A. Musmanno, a Pittsburgh-area jurist whose career stretched from the coal-country courtrooms of the 1920s to the world stage. He served in both World Wars, sat in the state legislature, and in 1947–48 presided over one of the Nuremberg trials that held Nazi leaders to account for their crimes. He capped his life with sixteen years on the Pennsylvania Supreme Court and authorship of sixteen books, and was laid to rest at Arlington National Cemetery.
