Joint Base San Antonio-Lackland is home to the 37th Training Wing (TRW), the largest training wing in the U.S. Air Force. We have a rich history of refueling the world’s greatest Air Force with trained and prepared Airmen ready to answer our nation’s call. Also known as the “Gateway to the Air Force,” the 37th TRW is home to four groups and one academy, each with a training mission.

More than 2,000 military and civilian members of the wing work to provide training and education to more than 79,000 students annually. We are providing foundational training and education to develop mission ready Airmen, Guardians, sister service members and international students.
