The 492nd Bombardment Squadron had its origin in the 80th Aero Squadron, which was organized at Kelly Field, San Antonio, Texas, on 15 August 1917. Early the next month the service nature of the unit became clearly apparent when it was redesignated the 80th Aero Squadron (Construction). Near the end of October the unit left San Antonio on the first lap of its journey overseas, and arrived at Garden City, New York, on 3 November. The Carpathia, on which it sailed for Europe some three weeks later, docked at Le Havre, France, on 14 December 1917.

Three days after arriving in France the 80th Squadron took station at the 2d Aviation Instruction Center in Tours. There it performed construction work until the end of World War I. Meanwhile, on 1 February 1918, it had been redesignated the 492nd Aero Squadron (construction). The unit returned to the United States aboard the Frederick late in January 1919 and was disbanded at Garden City on 13 February 1919.

In order to perpetuate the history and traditions of the 492nd Aero Squadron, the unit was reconstituted on 5 December 1936 and consolidated with the 492nd Bombardment Squadron which had been constituted and allotted to the Organized Reserve on 31 March 1924. The consolidation of the two units under the bombardment designation thus served to extend the history of the reserve squadron back to 15 August 1917. The 492nd Bombardment Squadron was stationed at Seattle, Washington, from the time it was constituted in 1924 until it was disbanded on 31 May 1942.

On 19 September 1942, less than four months after the 492nd Bombardment Squadron was disbanded, the 492nd Bombardment Squadron (H) was constituted. Having been assigned to the 7th Bombardment Group (H), it was activated at New Delhi, India, on 25 October 1942. There was no relation between this 492nd Bombardment Squadron (H) and the earlier 492nd Bombardment Squadron until 31 March 1960, when the Department of the Air Force, acting on the recommendation of the USAF Historical Division, consolidated the histories of the two units.

When the "new" 492nd Bombardment Squadron was activated in October 1942 it took station at Karachi Air Base, India, and immediately began preparations to enter combat with its parent group in the India-Burma Theater of Operations. The initial cadre consisted of one officer, First Lieutenant Herbert C. Boettcher, who assumed command of the unit and ten enlisted men. Personnel strength grew slowly at first. Yet by 1 February 1943, with 48 officers and 388 enlisted men, the squadron was considered a complete fighting unit. By that time it was equipped with eight B-24 Liberator aircraft, a number which ultimately grew to fourteen.

The squadron actually entered combat on 24 January 1943 when, operating from its base at Gaya, India, it bombed docks, shipping, and warehouses at Rangoon, Burma. That raid was followed early in February with an attack upon a railroad bridge at Myitnge. During the next five months, the squadron participated in repeated attacks on enemy communications lines in central and southern Burma, particularly in the area around Rangoon. Major targets in that respect included bridges, docks, and railroad yards at Rangoon; railroad bridges at Myintge, Pyinmana, and Sinthe; docks at Moulmein; and shipping in the Gulf of Martaban. The squadron's Liberators struck also at the Mingaladon Airport, a Japanese fighter base near Rangoon; the Mantu lead mines; and the Thilawa oil refinery.

The monsoon season, commencing in May 1943, slowed down combat operations. Only eight missions were flown in that month, for instance only four were completed in June. Squadron officers took advantage of this slack period to initiate a number of special training courses. They included armament, the geography of Burma, naval craft identification, navigation, radio code practice, and weather. In July 1943, however, the unit attacked enemy shipping in the far distant Port Blair in the Andaman Islands. During August, it persistently harassed shipping lanes in the Gulf of Martaban from Rangoon down to the Andaman Islands. A significant mission for September was an attack upon the Syrian oil refineries on the river opposite Rangoon.

During the last three months of the year, following the breakup of the monsoon, the squadron increased the tempo of its combat activities. In October communications lines in the Rangoon area and shipping lanes in the Andaman Sea felt the brunt of its bombers. The highlight of the unit's raids during November 1943 was an attack upon the Insein yards at Rangoon, reportedly the only place in Burma with facilities for repairing locomotives. In December, there were two 2,300-mile roundtrip flights to Bangkok, Thailand, the first for an attack upon the government docks there, and the second to bomb the Terminus Railroad Station.

On 22 January 1944, the 492nd Squadron took station at Madhaiganj Army Air Base, India. It began the second year of combat activities with continued efforts to destroy enemy-held communications into and within Burma by bombing bridges, docks and warehouses, locomotives and rolling stock, and railway marshalling yards on land, and cargo vessels and naval craft on the adjacent waters. Such attacks were interspersed at times, particularly in the late spring of 1944, with raids on airdromes, barracks areas, depots, gasoline plants, landing strips, supply dumps, and troop concentrations.

In mid-June 1944, after the beginning of the monsoon period, the squadron moved to Tezganon-Kurmitola, India, and for the time being ceased combat operations. Instead, it began transporting gasoline across the "Hump" to the Fourteenth Air Force in China. The first cargo was flown to Kunming on 20 June. These operations continued until after the first of October. During the period involved the unit had transported approximately 500,000 gallons of gasoline to China. Effective 5 October the squadron moved back to Madhainganj and began a "refresher" training course which included gunnery practice, formation flying, and dry-run bombing. Near the end of the month, much to the satisfaction of all personnel, the unit resumed regular combat activities.

Highlights of bombing operations for the remainder of the year were raids on the Ban Dara and the Geang Luang bridges on the Bangkok-Chiengmai railroad, an attack on the Pyinmana railroad yards, and a series of strikes along a 60-mile stretch of the Bangkok-Thanbyuzayt railway yards. For the greater part of December 1944, however, the squadron switched from blasting enemy lines of communications to destroying enemy stores. In December, also a small component of the 492nd Squadron left on six weeks of detached service in China. Based at Luliang, it engaged in hauling gasoline and other supplies to Sui-chuan and Liang-shan.

Early in 1945, the 492nd Bombardment Squadron supported British ground forces in the region north of Mandalay and east of the Irrawaddy River. After a resumption of attacks upon communications lines, it participated in a 2,500-mile mission in which it blasted railway roundhouses, rail sidings, and warehouses at Jumporn, a port on the Malay Peninsula south of Bangkok. In March, the squadron went all out against enemy communications in southern Burma, Thailand, and the Tenasserim Peninsula. That involved two raids on the Ban Tak Kam Bridge at Bandon, Thailand. In each instance the Liberators were in the air for over 17 hours, thought to be a record at the time for heavy bombers. Other highlights of the unit's combat activities during the closing weeks of the Burma campaign included a night raid up and down an 82-mile section of the Bangkok-Thanbyuzayt railroad, during which it destroyed two locomotives and numerous railroad cars. Later in the month the 492nd participated in a massive effort with other units of the 7th Bombardment Group to destroy the Burma-Thailand railroad. Using the unit's Liberators as "dive-glide" bombers on that occasion, the aircrews destroyed nine bridges.

After the fall of Rangoon on 7 May 1945, the 492nd Bombardment Squadron moved to Tezpur, India, and once again took on the mission of airlifting gasoline over the Hump into China. Some six weeks were required to refit the heavy bombers as substitute cargo carriers. The first mission was flown on 20 June. Normal operations continued throughout the summer. On 9 September, the squadron was notified that its airlifting mission would be considered as accomplished when it had transported a specified amount of gasoline to China. Speeding up operations, the aircrews completed the allotted task by 18 September. Six weeks later the squadron moved to Dudhkundi, India and thence to Kanchrapara on 19 November. It sailed from Calcutta aboard the General Black on 7 December 1945, and arrived at Camp Kilmer, New Jersey, on 5 January 1946. The unit was inactivated at Camp Kilmer the following day.

Effective 1 October 1946 the 492nd was redesignated a very heavy bombardment unit; activated at Fort Worth Army Air Field, Texas; and assigned to the 7th Bombardment Group, Fifteenth Air Force, Strategic Air Command. It was not until the last week in October, however, that the squadron received its first contingent of troops, 59 officers and 328 enlisted men on assignment from the 327th Bombardment Squadron. Lieutenant Colonel James H. Thompson assumed command of the newly activated 492nd. It then began a training program that was designed primarily for overseas operations. The squadron was equipped with the B-29 aircraft until late in the summer of 1948.

In April 1947 the 492nd Squadron engaged in three long-range missions. The first was as part of a mass formation flight from its home base to Los Angeles. Next it participated in a simulated bombing attack on Kansas City. Lastly, the squadron helped to provide an escort for President Miguel Aleman of Mexico in a flight from New Orleans to Washington, D.C., in May 1947.

The squadron spent a part of June and July 1947 on maneuvers in Japan. During August, most of its B-29s joined others of its companion units (9th and 436th Bombardment Squadrons) on a nonstop flight to Anchorage, Alaska, for the purpose of testing the immediate mobility of the 7th Bombardment Group. Before returning to Fort Worth, they engaged in flights that provided training in local approach procedures and in navigation. The following month the three squadrons deployed to Giebelstadt, Germany. While in Europe they flew several training missions in the central and southern parts of the continent.

The squadron received its first B-36 aircraft in June 1948. A few weeks thereafter it was redesignated a heavy bombardment unit. By January 1949 the squadron had completed the transition to the new bomber and had closed out its B-29 program. In March 1949 an aircrew assigned to the unit flew nonstop a distance of 9,600 miles (from Fort Worth to Minneapolis, Great Falls, Key West, Denver, Great Falls, Spokane, Denver, and back to Fort Worth) in 44 hours. As reported, this was the longest recorded flight to that date in a B-36 bomber.

The 492nd Bombardment Squadron remained assigned to the 7th Bombardment Group until the group was inactivated in June 1952. For several years thereafter it was assigned directly to the 7th Bombardment Wing. During that time it continued to operate from its Fort Worth station, known after 29 January 1948 as Carswell Air Force Base. Generally speaking, its primary mission all the while was to maintain a high degree of strategic striking power, whether operating on the squadron, group, wing, division, air force, or command level. Most of its operational activities were conducted at its home base and on various types of cross-country flights and special missions within the forty-eight states. Over the whole period, however, there were numerous deployments, maneuvers, and temporary duty missions outside the United States.

In August 1949, for instance, the 492nd Squadron inaugurated for the 7th Bombardment Group a series of routine training missions to Alaska. During February 1950, the squadron participated with other bombardment units of the group in an operational readiness test which a so involved flights to Alaska. For that purpose they deployed several aircraft to Eielson Air Force Base, Fairbanks. It served as a forward staging area from which simulated missions were directed against designated targets in the United States. In May 1950, the 492nd Squadron provided one of two B-36's on a mobility mission to Ramey Air Force Base, Puerto Rico.

On 17 July 1951 six aircraft and aircrews assigned to the squadron departed Fort Worth for Goose Air Base, Labrador, Canada. Thence they were dispatched on a navigation mission to Thule Air Base, Greenland. On the return flight from Goose Bay to Carswell, they made simulated attacks on Tampa, Florida; Birmingham, Alabama; and Fort Worth. Another deployment to Goose Bay on a unit simulated combat mission followed in March 1954. Meanwhile in December 1951, the squadron provided one of two heavy bombers of the 7th Bombardment Wing on a special mission to Sculthorpe, England. The purpose of this deployment was to participate in a Royal Air Force navigation mission on a noncompetitive basis, to effect a mutual exchange of ideas with Royal Air Force personnel, and to compare techniques in target study and briefing.

In August 1954 the 492nd Squadron participated in a 7th Bombardment Wing maneuver to North Africa on a simulated strike mission, flying non-stop the 4,600 miles to Nouasseur Air Base, French Morocco, which had been designated the post-strike headquarters. On the return flight to Carswell Air Force Base, the bombers made simulated attacks upon targets in the state of Mississippi. Eleven months later the entire 7th Wing deployed to North Africa for 60 days on a unit simulated combat mission. While there the 492nd Squadron, along with its companion tactical units, flew several missions to test the facilities of Nouasseur Air Base both As pre-strike and post-strike staging area for a B-36 task force. In February 1956 the squadron deployed about one-half of its aircraft and aircrews to North Africa as a part of a 19th Air Division Task Force operation. It involved a flight to Nouasseur Air Base by way of Loring Air Force Base, Limestone, Maine; a strike mission from Nouasseur to Dhahran, Saudi Arabia; a strike mission from Nouasseur and return; and redeployment to Fort Worth. A second mission overseas in connection with a 19th Air Division operations occurred in October-November 1956. On that occasion, in addition to the flights over and back to the home base in the United States, there were strike missions from Nouasseur and return, and from Nouasseur to Burtonwood Air Depot, England.

In December 1957, the entire 7th Bombardment wing began preparations for converting from the B-36 aircraft to the B-52 Stratofortress. Early in February, the wing officially became a B-52 organization, with the adoption of pertinent manning documents and equipment authorization. In March 1958 the commanding officer of the 492nd Bombardment Squadron, along with other officers in the wing, went to Castle Air Force Base, California, for transition training in the Stratofortress. The first of the B-52s arrived at Carswell in June, at which time the wing became in reality a jet bombardment organization. In January 1959, it attained a combat ready status in the B-52.

Effective 15 June 1959, less than six months after having completed the transition from the B-36 to the B-52 aircraft, the 492nd Bombardment Squadron was reassigned to the 4228th Strategic Wing, and took station at Columbus Air Force Base, Mississippi. It immediately began routine training Activities as a component of the 4228th Wing. Special operations and missions soon followed.
