Why did Liberty ships fail?

The brittle fractures that occurred in the Liberty Ships were caused by low notch toughness at low temperature of steel at welded joint, which started at weld cracks or stress concentration points of the structure. External forces or residual stress due to welding progress the fracture.

Who crewed the Liberty ships?

Each Liberty Ship was manned by a crew sized between 38 and 62; the crews were complimented by 21 to 40 US Navy personnel who operated the communications systems and weapons. The last Liberty Ship built was SS Albert M.

Eighteen different companies eventually built the engine.
