east of Attu. The following day, United States Army Engineers came ashore to begin construction of a runway suitable for B-29 Superfortress bombers. Tents were erected, a rudimentary electrical system, radios and some rough streets were laid down. A 10,000-foot runway was constructed, along with two 5,000-foot cross runways.The 404th Bombardment Squadron flew B-24 Liberator heavy bombers along with one Beechcraft AT-7, which was used for navigator training. The 344th Fighter Squadron flew both P-40 Warhawks and P-38 Lightnings. In addition, a North American AT-6 was utilized for pilot training. One RB-34, a UC-64A and numerous TB-26s were flown by the 15th Tow Target Squadron that was stationed on Shemya. The Navy assigned one squadron of Consolidated PB4Y-2 Privateers, which were single tail versions of the twin tail B-24. Many administrative and cargo aircraft, such as the C-47 "Gooney Bird" flew in and out of Shemya during the war. The dispersal aircraft standings were placed in the area to the north of the main runway. With the successful completion of the Aleutian Campaign in August 1943, Eleventh Air Force came within striking distance of the Japanese Kurile Islands, the northernmost being 750 miles to the south-southwest of Shemya. The Japanese had established a sizable defense complex on the northernmost islands, with most installations being located on Paramushiro, the largest island in the chain. It supported three airfields and the Imperial Japanese Army Kashiwabra Staging Area. In addition, it was the headquarters for the Imperial Japanese Navy Fifth Fleet, located on Kataoka. The mission of Eleventh Air Force was to take advantage of the new airfields on Shemya and Attu, and carry out offensive operations against the enemy forces in the Kuriles. Orders were issued in early July 1943 for the first bombing attack on the Japanese Home Islands since the April 1942 Doolittle Raid. Crews and aircraft were to be provided by the 21st, 36th and 77th bomb Squadrons. Initially Eleventh Air Force had little intelligence available about the Kurile Islands. IX Bomber Command coordinated with Navy personnel who were able to provide various documents, maps and other documents about the Islands. This included captured Japanese documents from Attu. From this information the command put together an accurate assessment of the Japanese military installations on the island chain. On 10 July 1943, eight B-25 Mitchells from the 77th Bombardment Squadron left Adak AAF and refueled at Alexai Point AAF on
