The 489th Attack Squadron is an active United States Air Force unit, stationed at Creech Air Force Base, Nevada, and operating General Atomics MQ-1 Predator and General Atomics MQ-9 Reaper unmanned aerial vehicles. It was active at Beale Air Force Base, California as the 489th Reconnaissance Squadron from 2011 to 2015.

The squadron was first activated as the 77th Aero Squadron in 1917. Redesignated as the 489th Aero Squadron, it served as a construction unit in France during World War I before returning to the US and being demobilized in 1919.

Through most of its existence, the squadron was named the 489th Bombardment Squadron. It served under this name from 1925 to 1942 in the Organized Reserve. The squadron served in the Mediterranean Theater of Operations during World War II, earning two Distinguished Unit Citations for actions in North Africa and Sicily. Inactivated after the war, it served briefly in the reserves a second time between 1947 and 1949. When Strategic Air Command reorganized its Boeing B-47 Stratojet wings as four squadron units the squadron was activated at Whiteman Air Force Base, Missouri, remaining active until 1962.

The squadron flies launch and recovery remotely piloted aircraft operations for General Atomics MQ-1 Predators and General Atomics MQ-9 Reapers. After launching these aircraft, they are handed off to the aircrew who execute the assigned mission, before returning them to the squadron for recovery operations.^[6]

The squadron was activated as the 77th Aero Squadron at Kelly Field, Texas in August 1917, and commanded by Capt. H. L. Mumma. In November 1917 the 77th moved to the Air Depot at Garden City, New York for deployment to the American Expeditionary Forces. On 4 December 1917, the squadron moved to the Philadelphia Port of Embarkation and boarded the transport SS Northland. On the Northland were 9 Aero Squadrons with 70 officers and 1,339 enlisted men. These 9 Squadrons were the 10th, 12th, 13th, 16th, 19th, 75th, 76th, 77th and 101st.^{[citation needed]}

In January 1918 a new numbering scheme for aero squadrons was set up. The numbers 400 through 599 were reserved for Aero Squadrons (Construction).^{[citation needed]} The 77th was redesignated as the 489th Aero Squadron (Construction).^[4] It served in France building facilities. The 489th returned to the States in February 1919 and went to Camp Stuart, Virginia. In March 1919 it was demobilized at Camp Lee, Virginia.^[4]

The first 489th Bombardment Squadron was constituted in the Organized Reserve in March 1924 and allotted to the Ninth Corps Area. The squadron was manned in 1925 at Boeing Field, near Seattle, Washington.^[4][7] It was assigned to the 349th Bombardment Group from 22 October 1925 until c. June 1929 for mobilization as part of the General Headquarters Reserve.^[8] The 489th was one of the few Air Corps units in the Organized Reserve that possessed facilities, equipment and, aircraft between the wars, including Curtiss B-2 Condor bombers.^[9] In June 1932, the 489 Aero Squadron was reconstituted and consolidated with the 489 Bombardment Squadron. The unit typically conducted its inactive training at Pearson Field or in Seattle. It performed its summer training at various Air Corps installations in the Pacific coastal region. The squadron was disbanded, along with all other Organized Reserve Air Corps units on 31 May 1942 and its remaining personnel were called to active duty individually.^[4][7]

The second 489th Bombardment Squadron was activated at Columbia Army Air Base, South Carolina on 20 August 1942 as one of the four original squadrons of the 340th Bombardment Group.^[4][10][11] However, it was not until September that the squadron received its initial cadre, mostly drawn from the 309th Bombardment Group.^[12] It completed Phase I and Phase II training^[d] at Columbia with North American B-25 Mitchells, then moved to Walterboro Army Air Field, South Carolina in November, where it completed Phase III training and departed for the Mediterranean Theater of Operations at the end of January 1943.^[4][12]

The squadron's ground echelon travelled by train to Camp Stoneman, California, where it boarded the USS West Point (AP-23) for the combat zone via the Pacific and Indian Oceans.^[4][13] The air echelon travelled by train to Kellogg Field, Michigan, where it received new B-25s to ferry across the Atlantic.^[14] It departed Morrison Field, Florida on 25 February 1943.^[15]

The squadron arrived at its first combat base, RAF Kabrit, Egypt in March 1943, with the air echelon arriving between 10 and 20 March and the ground echelon on 29 March.^[12] It began combat operations from Medenine Airfield, Tunisia in April, where the 340th Group flew its initial seven missions with the 12th Bombardment Group. Shortly thereafter, it moved to Sfax Airfield, Tunisia and began operations on its own.^[12] The 487th engaged primarily in air support and interdiction operations, targeting airfields, roads, bridges, road junctions, supply depots and marshalling yards. It participated in Operation Corkscrew, the reduction of defenses in Pantelleria and Lampedusa in June 1943. Although the squadron's operations were hindered by primitive living conditions at its base and unfavorable weather, the squadron supported the British Eighth Army in Tunisia and Allied forces in Operation Husky, the invasion of Sicily. For these actions, it was awarded a Distinguished Unit Citation (DUC).^[4][10]

As the Germans retreated from Sicily, the squadron attacked their evacuation beaches near Messina the following month. In September, it supported Operation Avalanche, the invasion of Italy near Salerno. During the first six months of 1944, it provided air support for the Allied drive on Rome. In March 1944, Mount Vesuvius erupted, covering 340th Group aircraft at Pompeii Airfield with volcanic ash. As a result, the squadron was forced to move to Gaudo Airfield.^[e] In April, it moved to Alesan Airfield, on Corsica.^[10]

The squadron sometimes bombed strategic targets as well. It operated against factories in Albania, Austria, Bulgaria, France, Greece, Italy, Tunisia and Yugoslavia. After September 1944, these targets included German lines of communication, particularly in the Alps, where it conducted raids on targets in the Brenner Pass. It also engaged in psychological warfare operations, dropping propaganda leaflets behind enemy lines. The squadron received a second DUC for action on 23 September 1944. The Italian Navy was attempting to block access to the heavily defended harbor of La Spezia by sinking a cruiser to block the entrance to the harbor. The squadron attacked and sank the cruiser before it could be maneuvered into position.^[10]

Just prior to V-E Day, the squadron returned to Italy, leaving for the United States in July 1945. The air echelon ferried its Mitchells, turning them in upon arrival in the United States, while the ground echelon returned by ship, leaving Naples on 28 July and arriving at Hampton Roads, Virginia on 7 August.^[16] It arrived at Seymour Johnson Field, North Carolina in August,^[4] although its personnel were granted leave and the squadron only began to reassemble in September.^[12] It returned to Columbia in October, but was inactivated in November.^[4]

The 489th was reactivated as a reserve unit under Air Defense Command (ADC) at Davis Field, Oklahoma on 10 November 1947.^[4] The 177th AAF Base Unit (later the 177th AF Base Unit, 2592d AF Reserve Training Center), located at Tinker Air Force Base, 140 miles to the west, oversaw its training. Through July of 1948 the unit had only a single airplane assigned full time, and squadron strength was reduced by the end of the year as a dozen qualified pilots left the squadron and returned to active duty.^{[17] [f]} In 1948 Continental Air Command assumed responsibility for managing air reserve and Air National Guard units from ADC.^[18] President Truman’s reduced 1949 defense budget required reductions in the number of units in the Air Force,^[19] and the 489th was inactivated in June 1949^[4]

From 1958, the Boeing B-47 Stratojet wings of Strategic Air Command (SAC) began to assume an alert posture at their home bases, reducing the amount of time spent on alert at overseas bases. The SAC alert cycle divided itself into four parts: planning, flying, alert, and rest to meet General Thomas S. Power's initial goal of maintaining one-third of SAC's planes on fifteen-minute ground alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike.^[20] To implement this new system B-47 wings reorganized from three to four squadrons.^[20][21] The two 489th Squadrons were consolidated as a single unit, which was activated at Whiteman Air Force Base as the fourth squadron of the 340th Bombardment Wing.^[2] The alert commitment was increased to half the squadron's aircraft in 1962 and the four squadron pattern no longer met the alert cycle commitment, so the squadron was inactivated on 1 January 1962.^[2][21]

The squadron was activated as the 489th Reconnaissance Squadron on 26 August 2011 at Beale Air Force Base near Marysville, California as a component of the 9th Operations Group, flying Beechcraft MC-12W Liberty aircraft. It was inactivated on 10 May 2015.^[2] The squadron used Beale as the home base for the MC-12W, while it deployed crews trained to pursue elusive high-value targets such as insurgent kingpins in the Middle East.^[22] In 2015, all aircraft were transferred to United States Southern Command, the Army, and other US government agencies.^[23]

The squadron was redesignated as the 489th Attack Squadron at Creech Air Force Base under the 432d Operations Group, on 2 December 2016.^[2] It operates General Atomics MQ-1 Predator and General Atomics MQ-9 Reaper unmanned aerial vehicles.^[2][24] Members of the unit deploy to meet mission needs, while other members stay at Creech to meet home station requirements such as training, professional development and personal readiness.^[6] The squadron was the first in the Air Force to use the MQ-9's automated takeoff and landing capability.^[25]
