U-Tapao–Rayong–Pattaya International Airport (; ) also spelled Utapao and U-Taphao, is a joint civil–military public airport serving Rayong and Pattaya cities in Thailand. It is in Ban Chang District of Rayong Province. It also serves as the U-Tapao Royal Thai Navy Airfield, home of the Royal Thai Navy First Air Wing. U-Tapao is the home of a large Thai Airways maintenance facility, servicing that airline's aircraft as well as those of other customers. Due to the blockade of Bangkok's airports by opposition protesters, U-Tapao briefly became the main air gateway to Thailand between 26 November and 5 December 2008. As both of Bangkok's international airports essential to the country's tourist boom are operating beyond capacity as of 2015, U-Tapao in particular has been eyed as an alternate international gateway due to its relative proximity to the capital. Location U-Tapao lies approximately southeast of Bangkok, south of Sukhumvit Road at Km. 189, near Sattahip on the Gulf of Thailand, about a 45-minute drive from Pattaya (Thailand's most popular beach resort). History Vietnam War U-Tapao was built by the United States to accommodate B-52 bombers for missions in Vietnam, Laos, and Cambodia during the Vietnam War. Construction began on 15 October 1965 and was completed on 2 June 1966. U-Tapao was the primary Southeast Asian airfield for US Air Force B-52 Stratofortress bombers, called "Bee-hasip-sawng" (B-52) by the local Thais.

The USAF B-52s made regular sorties over North Vietnam and North Vietnamese-controlled areas in Laos, carrying an average of 108 500-pound and 750-pound bombs per mission. U-Tapao was a regular stop on Bob Hope's Christmas shows for the troops. November 2008 protests in Bangkok With the temporary closure of Suvarnabhumi Airport and Don Mueang Airport in late November 2008 because they had been occupied by anti-government protestors, U-Tapao became for a time Thailand's main supplementary international gateway. Many airlines arranged special flights to and from U-Tapao to ferry international passengers stranded by the closure of the Suvarnabhumi Airport. Several governments including Italy, Macau and Spain also sent chartered flights to evacuate residents. As many as 100,000 passengers were stranded in Thailand until early December.
