Greater Orlando is a popular tourist destination thanks to the many theme parks in the area. Famous attractions include Walt Disney World, SeaWorld Orlando and Universal Orlando. Millions of tourists visit these and other attractions every year. In 2015, the Orlando area attracted 68 million people.
The citrus industry historically dominated the Orlando area economy, but has declined over the past 100 years. The Christmas 1989 impact freeze proved particularly damaging to commercial citrus farming within Greater Orlando. There are still three major orange juice plants remaining in the area: Cutrale Citrus Juices in Leesburg; Florida's Natural Growers in Umatilla; and Silver Springs Citrus in Howey-in-the-Hills. Minute Maid maintains a major juice flavoring plant in Apopka. Other agricultural pursuits, particularly cattle farming, remain important parts of the Central Florida economy, but are now all located on the outer fringes of the metro area. Orlando is also a major food processing center.
Metro Orlando has served as a major military defense and aerospace center since World War II. The most prominent defense contractor in the area is Lockheed Martin, which operates both a laboratory and a manufacturing facility in Orlando. Military presence began in the 1940s, with the opening of McCoy Air Force Base and the Orlando Naval Training Center. McCoy AFB was a major hub of B-52 Stratofortress operations. McCoy AFB was split between the city and NTC Orlando in 1974, and NTC Orlando closed in the mid-1990s. McCoy AFB is now the location of the Orlando International Airport. Farther north in Sanford, the Orlando Sanford International Airport was originally Naval Air Station Sanford.
