Richmond, California · 8–12 November 1942 · Kaiser Richmond Yard No. 2

Four Days, Fifteen Hours

U-boats were sinking ships faster than the Allies could build them. So America learned to build a 441-foot cargo ship in less than five days.

Workers crowd the ways as a newly launched Liberty ship leaves its building dock at the Kaiser yard in Vancouver, Washington.

The moment · 15:27 · 12 November 1942

Sunday, one minute past midnight: the keel goes down. Cranes swing whole deck sections and fitted-out deckhouses onto the hull. Two hundred fifty thousand parts. Fourteen million pounds. Four days and fifteen hours after the keel, the bottle breaks. The Robert E. Peary slides into San Francisco Bay.

In 1942 German U-boats hit more than 1,300 Allied ships. Every tank, shell and soldier bound for Britain, Russia or the Pacific had to cross an ocean, and the cargo ships to carry them were going to the bottom. The answer was one plain freighter, built by the thousand, by men and women who had never built a ship before.

  1. A British order

    Britain is losing merchant ships faster than its own yards can replace them. Its shipping mission signs contracts for 60 freighters of a plain, cheap design from J.L. Thompson & Sons of Sunderland. Thirty will come from a new yard on the tide flats of Richmond, California, run by a group of road and dam builders led by Henry J. Kaiser. None of them has ever built a ship. Work on the yard starts that month.

  2. The emergency program

    President Roosevelt announces an emergency program of 200 cargo ships modeled on the British design. Adm. Emory S. Land’s Maritime Commission reworks the plans for speed: oil-fired boilers, and welded seams in place of rivets. The result is the EC2: 441 feet 6 inches long, 57 feet wide, a 2,500-horsepower steam engine, 11 knots and about 10,800 tons of cargo.

  3. Liberty Fleet Day

    From dawn to dark, fourteen ships slide into the water on the Atlantic, the Pacific and the Gulf. The first is the SS Patrick Henry, at Bethlehem-Fairfield in Baltimore. In a radio address the President recalls Patrick Henry’s demand for liberty or death, and the new ships take a name: Liberty ships. He asks for a launching a day, then two a day.

  4. Wendy the Welder

    Kaiser’s yards build ships the way Detroit builds cars. Bottoms, bulkheads and deckhouses are made in sheds and lifted onto the ways by giant cranes. Welding replaces riveting, and a new hand can learn it in days. In July 1942 Phyllis Gould becomes one of the first six women welders at Richmond. By war’s end 27 percent of Richmond’s shipyard workers are women, and the town has grown from 20,000 people to more than 100,000.

  5. Ten days in Portland

    At Oregon Shipbuilding, run by Kaiser’s son Edgar, the keel of the SS Joseph N. Teal goes down on 13 September. Ten days later she is launched, with President Roosevelt watching from his car and his daughter Anna swinging the bottle. Down in Richmond, yard manager Clay Bedford, a dam builder who had never built a ship before 1940, sets out to beat it.

  6. Keel down

    Yard No. 2 builds its 47th hull in pieces ahead of time and stages them beside the way. At one minute past midnight on Sunday the keel is laid. The bottom shell and inner bottom follow, and the boilers are aboard by mid-morning. Bulkheads and the shaft tunnel go in next. Seventeen banks of welding machines line each side of the hull, ready for the next section.

  7. Up from the ways

    On the second day the upper deck goes on, in seven big sections instead of the usual 23, with the forepeak and the fantail. On the third day come the masts, the cargo booms and the deckhouses, lifted aboard already fitted out down to the bunks and the fans. On the fourth day the crews finish the wiring, the welding and the paint, and set the forward gun platform.

  8. Into San Francisco Bay

    Four days and fifteen and a half hours after the keel went down, Mrs. James F. Byrnes breaks the bottle and the SS Robert E. Peary slides into San Francisco Bay. About 250,000 parts weighing 14 million pounds have become a ship. She is delivered three days later, and on 22 November she sails for the South Pacific loaded with food and war supplies.

  9. The bridge of ships

    Eighteen yards on three coasts build 2,710 Liberty ships between 1941 and 1945, the most ever built to one design. By 1943 the country is turning out about three a day. Kaiser’s seven yards deliver 1,490 ships of all types, 27 percent of everything the Maritime Commission builds, and Richmond’s four yards alone launch 747. The convoys carry the war to every front, and the U-boats lose the race.

The builders

Founder, Kaiser ShipyardsHenry J. Kaiser

Left school at about 13, then built roads and helped build the Hoover, Bonneville and Grand Coulee dams. He had never built a ship before 1940. His seven wartime yards turned out 1,490 ships, more than a quarter of the Maritime Commission’s total.

General Manager, Oregon ShipbuildingEdgar F. Kaiser

Henry’s son. Started as a shovel foreman on Boulder Dam and rose to superintendent of canyon excavation. Ran Oregon Shipbuilding in Portland, where his crews built the Joseph N. Teal in ten days and set the record Richmond went after.

Naval constructor, Naval Academy class of 1902, awarded the Navy Cross for his submarine design work in the First World War. Chaired the Maritime Commission from 1938 and ran the War Shipping Administration from 1942, steering the whole Liberty ship program.

Born at Camp Lewis, Washington. In July 1942 she became one of the first six women welders at the Richmond yards, and her two sisters and mother followed. She welded until the war ended, then fought for decades to honor the Rosies.

After

The Robert E. Peary went to war on 22 November 1942. She carried supplies to New Caledonia and Guadalcanal, crossed to the Atlantic in 1943, and on 7 June 1944 brought men and equipment to Omaha Beach. She kept running to Normandy until September.

Two Liberty ships still sail. The Jeremiah O’Brien, built in South Portland, Maine, in 1943, made 11 round trips to Normandy. In 1994 she steamed back across the Atlantic for the 50th anniversary of D-Day, the only large ship of the original fleet to return. The John W. Brown, launched in Baltimore in 1942, made 13 wartime voyages and still steams out of Baltimore.

In 2000 Congress made the old Richmond yards the Rosie the Riveter WWII Home Front National Historical Park. Its memorial stands on the ground of Yard No. 2, where the Peary was built.
