The Federal Shipbuilding Co., a U.S. Steel subsidiary based in South Kearny, played a key role in supplying ships for both World Wars. Scarcely six months after Pearl Harbor, according to John Cunningham in "Made in New Jersey," Federal "completely proved its might. On one day alone in May 1942, the company launched four destroyers. By 1943, Federal Shipbuilding was employing 52,000 people and building ships faster than any other yard in the world."
