previous track for USAF navigators was termed Joint Undergraduate Navigator Training (JUNT). Today, all USAF Undergraduate CSO Training (UCSOT) for all USAF aircraft is consolidated at NAS Pensacola as a strictly USAF organization and operation under the 479th Flying Training Group (479 FTG), an Air Education and Training Command (AETC) unit. The 479 FTG is a tenant activity at NAS Pensacola and a GSU of the 12th Flying Training Wing (12 FTW) at Randolph AFB, Texas. The 479 FTG operates USAF T-6A Texan II and T-1A Jayhawk aircraft. Other tenant activities include the United States Navy Flight Demonstration Squadron, the Blue Angels, flying F/A-18 Hornets and a single USMC C-130T Hercules; and the 2nd German Air Force Training Squadron USA (– abbreviated "2. DtLwAusbStff"). A total of 131 aircraft operate out of Sherman Field, generating 110,000 flight operations each year. The National Naval Aviation Museum (formerly known as the National Museum of Naval Aviation), the Pensacola Naval Air Station Historic District, the National Park Service-administered Fort Barrancas and its associated Advance Redoubt, and the Pensacola Lighthouse and Museum are all located at NAS Pensacola, as is the Barrancas National Cemetery. History The site now occupied by NAS Pensacola has been controlled by varying nations. In 1559, Spanish explorer Don Tristan de Luna founded a colony on Santa Rosa Island, considered the first European settlement of the Pensacola area. The Spanish built the wooden Fort San Carlos de Austria on this bluff in 1697–1698. Although besieged by Indians in 1707, the fort was not taken. Spain was competing in North America with the French, who settled lower Louisiana and the Illinois Country and areas to the North. The French destroyed this fort when they captured Pensacola in 1719. After Great Britain defeated the French in the Seven Years' War and exchanging some territory with Spain, British colonists took over this site and West Florida in 1763. In 1781, as an ally of the American rebels during the American Revolutionary War, the Spanish captured Pensacola. Britain ceded West Florida to Spain following the war. The Spanish completed the fort San Carlos de Barrancas in 1797. Barranca is a Spanish word for bluff, the natural terrain feature that makes this location ideal for the fortress. Pensacola was taken by General Andrew Jackson in November 1814 during the War of 1812 between Great Britain and the United States. British forces destroyed Fort San Carlos
