Walker Air Force Base is a former United States Air Force base located three miles (5 km) south of the central business district of Roswell, New Mexico. It was opened in 1941 as an Army Air Corps flying school and was active during World War II and the postwar era as Roswell Army Air Field (RAAF). During the early years of the Cold War, it became the largest base of the Strategic Air Command. It is also known for the Roswell UFO incident, an event that occurred on 4 July 1947. It is alleged that a "flying disc" crashed during a severe thunderstorm near the base at Corona, New Mexico.

Walker AFB was named after General Kenneth Newton Walker, a native of Los Cerrillos, New Mexico, who was killed during a bombing mission over Rabaul, New Britain, Papua New Guinea, on 5 January 1943. His group scored direct hits on nine Japanese ships before being intercepted by enemy fighters. Walker was last seen leaving the target area with one engine on fire and several fighters on his tail, and he was awarded the Medal of Honor posthumously by President Franklin D. Roosevelt in 1943. The base was renamed in his honor on 13 January 1948. Funding cutbacks during the Vietnam War led to the closure of the base in 1967. It was subsequently converted into a civil airport and renamed Roswell International Air Center.

History What became Roswell Army Air Field was acquired by the United States Army Air Forces in 1941 from rancher David Chesser for the purpose of establishing a Military Flying Training Center and Bombardier School. From the beginning, it was designed as a large, expansive facility, given the excellent flying weather in New Mexico. The airfield consisted of seven concrete runways, two parallel North/South 7329x200 and 7000x200; two parallel NE/SW 7200x200 and 5655x200; two parallel NW/SE, 6964x200 and 5900x200 and one E/W runway 6884x200 (E/W).

In addition, no less than nine auxiliary landing fields for overflow and touch/go landing/takeoffs were established in the area. Enough construction was completed for the base and airfield to be activated and assigned to the United States Army Air Corps Training Command on 20 September 1941.

World War II The Roswell Army Flying School was activated on 20 September 1941. Its mission was the training of third-phase aviation cadets in twin-engine aircraft. The school operated Beechcraft AT-11 Kansan twin-engine trainers and four (548th, 549th, 550th and 551st) Two-Engine Flying Training Squadrons. In addition to the flying school the Bombardier's school, operated 3 training squadrons also flying the AT-11.

In 1943, three additional twin engine flying training squadrons were added and two additional squadrons were added to the Bombardiers school as additional runways became available. Over 300 trainers filled the large parking ramp, which included Vultee BT-13 and BT-15 Valiant single engine trainers and Cessna AT-17 twin-engine trainers.

Until the fall of 1944, Second Air Force provided all Boeing B-29 Superfortress transition training for the Army Air Forces. Then, on 12 September 1944, HQ AAF directed Training Command to establish B-29 schools for the transition of crews consisting of pilots, copilots, and flight engineers. Initially, there were few B-29s available for Training Command to conduct training. However, by January 1945 Roswell AAF had transitioned and the 3030th AAF Base Unit (Pilot School, Specialized Very Heavy) which specialized in B-29 Superfortress 4 engine pilot transition and bombardier training was activated.

Although there was a bombing target adjacent to the runway, the only items dropped from an aircraft were bags of sand or flour. The practice bombing and gunnery ranges were due south of the air field and on Matagorda Island along the Texas Gulf coast.

In addition to the airfield, the Roswell Prisoners of War (POW) camp was built for up to 4,800 POWs. Most of the POWs housed at the camp were German and Italian soldiers captured during the North African campaign. The POWs were actually used as construction laborers on local projects and many of Roswell's parks were built by POWs. The Spring River, which passes through downtown Roswell, was lined with concrete and stones using POW labor. The prisoners used stones of different colors to form an Iron Cross in the riverbed.

With the end of World War II, the training mission at Roswell AAF ended on 1 November 1945. The base was designated as a permanent Army Air Force facility and jurisdiction of the base was transferred to 238th Army Air Forces Base Unit, Second Air Force, Continental Air Command.

Strategic Air Command

The 509th Composite Group returned from its wartime base on Tinian and relocated to Roswell on 6 November 1945, initially being assigned to Second Air Force under Continental Air Forces. With demobilization in full swing in late 1945, much juggling of units was being performed by the Army Air Forces. It was reassigned to the 58th Bombardment Wing at Fort Worth Army Airfield on 17 January 1946. The 509th was assigned to Strategic Air Command on 21 March 1946, being one of the first eleven organizations assigned to SAC.

In April 1946 many of the group's Boeing B-29 Superfortress aircraft deployed to Kwajalein as part of Operation Crossroads, a series of atomic bomb tests. The remainder became the core of two new squadrons activated as part of the group, the 715th Bomb Squadron and the 830th Bomb Squadron. In May 1946, the Army Air Forces gave the newly formed SAC the responsibility of delivering the atomic bomb. Only the 509th was trained and ready for the atomic bomb mission.

Squadrons assigned to the 509th were: 393d Bombardment Squadron 715th Bombardment Squadron 830th Bombardment Squadron

On 10 July 1946, the group was renamed the 509th Bombardment Group (Very Heavy). With the creation of the United States Air Force as a separate service, the group became the combat component of the 509th Bombardment Wing on 17 November 1947, although it was not operational until 14 September 1948, when Colonel John D. Ryan was named commander.

The wing pioneered a new concept on 30 June 1948, when the 509th Air Refueling Squadron was activated as part of the 509th BW, along with the 43rd ARS at Davis-Monthan AFB, Arizona, the first such units ever created. With the addition of KB-29M tankers, the 509th's bombers could reach virtually any point on Earth. In June 1950, it began receiving the upgraded version of the B-29, the Boeing B-50A Superfortress. When the huge Convair B-36 Peacemaker joined the Air Force inventory, the "Very Heavy" designation was dropped. The 509th – like all other B-29 and B-50 wings – was redesignated "Medium".

In January 1954, the Boeing KC-97 aerial tanker replaced the aging KB-29Ms, and the wing entered the jet age in June 1955 when it received the first all-jet bomber: the Boeing B-47 Stratojet. On 16 June 1958 the 509th Bombardment Wing was transferred to Pease AFB, New Hampshire.

The 468th Bombardment Group arrived at Roswell on 12 January 1946 from West Field, Tinian. At Roswell the group exchanged aircraft and equipment with the 509th, with the lowest-hour and most reliable B-29 aircraft being transferred then being sent to Carswell Air Force Base, Texas for modification to Silverplate (Atomic Bomb-Capable) specifications. The balance of the aircraft were sent to storage at Davis-Monthan AFB Arizona or Pyote Army Airfield Texas. The group was inactivated on 31 March 1946.

33rd Fighter Group

The 33rd Fighter Group was assigned to Roswell on 25 August 1947, being transferred from Bad Kissingen AB, West Germany after a year of occupation duty. Squadrons of the 33rd at Roswell were: 59th Fighter Squadron (F-51, F-84) 60th Fighter Squadron (F-51, F-84)

The group was initially attached to the 509th Bombardment Group to perform fighter escort duties. The group was redesignated as the 33rd Fighter Wing on 15 October 1947. It remained at Roswell until 16 November 1948 when it was transferred to Otis Air Force Base, Massachusetts.

6th Bombardment Wing

The 6th Bombardment Wing, Medium was activated on 2 January 1951 at Walker AFB and was equipped with Boeing B-29 Superfortress. On 1 August 1951, the 307th Air Refueling Squadron was attached to the wing. It flew KB-29 tankers until inactivated 16 June 1952. The 6th, along with the 509th Bombardment Wing at Walker formed the SAC 47th Air Division until June 1958 with the reassignment of the 509th to Pease AFB.

However the three squadrons of the wing (24th, 39th, 40th) were soon re-equipped with SAC's new heavy bomber, Convair B-36D Peacemaker and the unit was redesignated the 6th Bombardment Wing (Heavy).

The B-36D was the first major production model of the bomber, being equipped with two pairs of General Electric J47-GE-19 turbojets in pods underneath the outer wings to assist the six R-4360-41 piston engines. The B-36D flew fairly well on just four or even three piston engines, so it was common practice to shut down some of the engines during cruise. The turbojets were normally used only for speed dashes over the target area or for takeoff. The 6th conducted strategic bombardment training with the aircraft, being deployed at Andersen AFB, Guam from October 1955 to January 1956.

The phaseout of the B-36 began in 1957, when the wing began receiving the new Boeing B-52 Stratofortress jet bomber. They were flown by its existing squadrons. The last of the B-36s departed Walker in 1958.

To provide air defense of the base, United States Army Nike Hercules Surface-to-air missile sites were constructed during 1959 near Roswell (W-10) and Hagerman (W-50) , New Mexico. The sites were selected and built, the battalion activated, batteries were assigned, and then the whole setup was shut down. Many of the personnel were later transferred to Omaha, Nebraska for the protection of Offutt AFB.

In September 1959, the 24th and 30th Bombardment Squadrons joined the newly assigned 4129th Combat Crew Training Squadron to train B-52 and KC-135 crews. The 40th Bombardment Squadron continued flying operational missions until 10 June 1960. From 10 June 1960 to 1 December 1961 the wing flew a few operational missions in a non-combat ready status. The 40th Squadron returned to operational status on 1 December 1961. The other two bomb squadrons regained tactical status on 5 September 1963. The 39th Squadron discontinued a few days later, but the 24th and 40th continued global bombardment training through December 1966, when they phased down for inactivation.

The 6th Air Refueling Squadron, flying early-model KC-135A aircraft, was assigned to Walker AFB from 3 January 1958. On 3 February 1960, a "short-tail" (non-hydraulic-power-assisted rudder) KC-135A crashed during takeoff in strong and gusty crosswinds. The pilot failed to maintain directional control, rotated the aircraft 5–10 knots too early and the aircraft settled onto the dirt apron of the runway, shed two engines, plowed through the aircraft parking area and came to rest in an aircraft hangar. This single crash resulted in the destruction of three KC-135 aircraft and the deaths of eight military personnel.

The wing was redesignated the 6th Strategic Aerospace Wing on 1 May 1962. On 25 June 1965, the 310th Air Refueling Squadron was attached to the wing. It flew KC-135A aircraft until the base was closed and the unit was moved to Plattsburgh AFB, NY on 25 January 1967.

579th Strategic Missile Squadron

In 1960, Atlas missile silos were constructed around the Roswell area. Reportedly, the first Atlas missile to arrive in Roswell received a welcoming parade. On 2 January 1961, the 579th Strategic Missile Squadron was activated as part of the 6 BW at Walker. New Mexico's Governor Edwin L. Mechem gave the keynote speech at a Site 10 ceremony held on 31 October 1961, in which the first missile site was turned over to the Air Force.
