In 1928, Webb began his namesake company which was a construction contractor. He received many military contracts during World War II, including the construction of the Poston War Relocation Center near Parker. Poston interned over 17,000 Japanese-Americans and at the time was the third largest "city" in Arizona. Webb was associated with Howard Hughes and played golf with Hughes, Bing Crosby, Bob Hope and Barry Goldwater. A former semipro baseball player and a lifelong fan, Webb and partners Dan Topping and Larry MacPhail purchased the New York Yankees in 1945 for $2.8 million from the estate of Col. Jake Ruppert, Jr.. After buying out MacPhail in October 1947, Webb and Topping remained owners of the Yankees until selling the club to CBS in 1964. During those twenty seasons, the Yankees were in fifteen World Series and won ten of them. In 1946 and 1947, mob bossBenjamin "Bugsy" Siegel hired Webb as the construction foreman for the Flamingo Hotel and Casino in Las Vegas. After boasting about his claim that he'd personally had killed 16 men, Siegel said to Webb, "Del, don't worry, we only kill each other." In 1948, Webb was contracted to build 600 houses and a shopping center called Pueblo Gardens in Tucson, Arizona. San Manuel, Arizona a miningcompany town and currently a resort town followed. Established in 1953, the town was built by Webb for The Magma Copper Company. It required the building of streets, shopping centers, schools, a hospital and parks. This was a prelude to Sun City, Arizona, which was launched January 1, 1960, with five home models, a shopping center, recreation center and golf course. The opening weekend drew 100,000 people, ten times more than expected, and resulted in a Time magazine cover story. In between these two projects, in 1951, Webb was given the huge contract to build the Hughes Missile Plant in Tucson, Arizona.
Webb was portrayed by Andy Romano in the 1991 film Bugsy. He was elected to the Gaming Hall of Fame in 2000. The Del Webb Middle School, named in his honor, opened in Henderson, Nevada in 2005. A charitable foundation named for him funds medical research in Nevada, Arizona, and California. One of the main thoroughfares in Sun City, Arizona, is named "Del Webb Boulevard."
