The Texas Air National Guard origins date to 14 August 1917 with the establishment of the 111th Aero Squadron as part of the World War I United States Army Air Service.
The 111th served at Kelly Field, San Antonio, then after the 1918 Armistice with Germany was demobilized in 1919.

The Militia Act of 1903 established the present National Guard system, units raised by the states but paid for by the Federal Government, liable for immediate state service.
If federalized by presidential order, they fall under the regular military chain of command.
On 1 June 1920, the Militia Bureau issued Circular No.1 on organization of National Guard air units.

The unit was reorganized with the establishment of a permanent air service in 1920, forming in the old Houston Light Guard Armory.
The 111th Observation Squadron received Federal Recognition on 29 June 1923, as part of the 36th Division, Texas Air National Guard.
It is one of the 29 original National Guard Observation Squadrons of the United States Army National Guard formed before World War II.
The 111th Observation Squadron was ordered into active service on 25 November 1940 as part of the buildup of the Army Air Corps prior to the United States entry into World War II.

On 24 May 1946, the United States Army Air Forces, in response to dramatic postwar military budget cuts imposed by President Harry S. Truman, allocated inactive unit designations to the National Guard Bureau for the formation of an Air Force National Guard.
These unit designations were allotted and transferred to various State National Guard bureaus to provide them unit designations to re-establish them as Air National Guard units.

The modern Texas ANG received federal recognition on 27 January 1947 as the 136th Fighter Group at Love Field Airport, Dallas.
It's 181st Fighter Squadron was equipped with F-51D Mustangs and its mission was the air defense of the state.
 Other units assigned to the 136th in 1947 were the 111th Fighter Squadron at Ellington Field, Houston, and the 182d Fighter Squadron at Kelly Field, San Antonio.
They were also equipped with F-51D Mustangs.
18 September 1947, however, is considered the Texas Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act.

On 1 July 1957 the 111th Fighter-Interceptor Squadron in Houston was authorized to expand to a group level, and the 147th Fighter Group (Air Defense) was allotted by the National Guard Bureau, extended federal recognition and activated.
 On 1 August 1961 the 182d FIS in San Antonio was expanded to become the 149th Fighter-Interceptor Group.

Today, the 136th Airlift Wing (136 AW) provides global airlift for Air Mobility Command; the 147th Attack Wing (147 AW) flies the MQ-9 Reaper reconnaissance/strike RPA and the 149th Fighter Wing (149 FW) flies the Block 30 F-16C/D Fighting Falcon tactical fighter-bomber.

From 2001 through 2007, elements of every Air National Guard unit in Texas were activated in support of the Global War on Terror.
Flight crews, aircraft maintenance personnel, communications technicians, air controllers and air security personnel deployed to Iraq, Afghanistan, Qatar, Israel, and other locations throughout Southwest Asia.
Additionally, in 2005 elements of all the units were activated to provide relief after Hurricane Katrina and Hurricane Rita.
