The 805th Engineer Aviation Battalion was a United States Army Air Force unit activated on February 12, 1941 at MacDill Field (Army Air Base) near Tampa, Florida.


* The primary mission of the battalion was to build aviation facilities for fighter and bomber aircraft.

* Deactivated shortly after World War II


* Florida The 805th Engineer Company, Aviation (Separate) was created from the inactive 2nd Battalion, 28th Engineers, Aviation. After activation at MacDill Field in Florida, the company left the base on March 20, 1941; traveling via rail to Charleston, South Carolina, for embarkation to the Panama Canal Zone.

* Panama The company arrived in Panama on March 26, 1941 and were encamped at Albrook Field. On June 28, 1941 the 805th was increased to battalion strength and subdivided into four companies (Headquarters,A,B,C). On June 12, 1942, the transport ship S.S. Sixaola was torpedoed by U-159 while transporting a detachment of the 805th to Guatemala; 28 crewmen were killed and the 805th lost a large amount of construction equipment when the ship sank near Colon, C.Z. The 805th remained in Panama until March 30, 1943, having constructed numerous airfields in Panama, Guatemala, Ecuador, and the Galapagos Islands. The battalion traveled from Albrook Field to the New York Navy Yard on the USAT Frederick Funston, arriving there on April 7, 1943. The battalion then traveled by rail to Richmond (Virginia) Army Air Base for training and furlough.

* Hawaii The battalion departed Richmond, Virginia, in November, 1943, traveling by rail to Camp Stoneman, California. After twelve days the battalion departed San Francisco on the ATS Lurline, a former luxury liner. The battalion arrived at Pearl Harbor on December 20, 1943, and were encamped at Bellows Field. While stationed on Oahu the battalion was assigned to lengthen and widen the landing strip at Kahuku, on the northern end of Oahu. The runway was being modified to accommodate the new B-29s, which were still on the manufacturing line in the United States. This runway was going to be a stopover point for the planes on their way to the Western Pacific.

* Saipan On June 7, 1944, the battalion departed Oahu on the SS Mormacport. On June 25, 1944, the 805th arrived offshore at Saipan, an island in the Marianas chain. The battalion landed on June 27, (d-day +2) and commenced repairing and expanding the existing Japanese airfield to accommodate B-29s. Four months later, the first B-29s landed at the field; in November, 1944, the first B-29 missions were on their way to Japan.

* Ie Shima On May 23, 1945, the 805th boarded LSTs anchored in Tanapag Harbor off Saipan. On May 29, 1945, the battalion arrived off the coast of Okinawa, but was assigned runway construction on Ie Shima (Iejima), a small island off the northwest coast of Okinawa. The battalion cam ashore on Ie Shima near the site of war correspondent Ernie Pyle's death. Pyle had been killed by a hidden Japanese machine gunner during the initial landings on Ie; at this point the site was only marked by an upturned rifle stuck in the mud with Pyle's helmet on it. It was later marked by a monument created by the 77th Infantry. As had been the case on Saipan, the 805th was assigned runway construction for B-29 operations. These runways were constructed primarily from native coral quarried from the island's interior. On August 10, 1945, the 805th completed runway "B" on Ie Shima; the runway was 7000 feet long and was the first all-American built runway in the Ryukyus Islands. On August 19, 1945, the Japanese surrender party arrived on Ie Shima in two Betty Bombers, each repainted white with green crosses in place of the rising sun. The Japanese transferred to a C-54 transport for the trip to Manila and a meeting with General MacArthur to review the terms of surrender. Members of the 805th were allowed to line the sides of the runway as the Japanese delegation landed and departed, signaling the imminent end of World War II. [1]

Post World War II

The unit was reduced to reserve status on January 4, 1946, at Fort Lawton, Washington.
