Interesting. The first raid over the Kuriles was conducted by B-25's from Alexei Field on Attu, early July 1943. I don't think you can reach Paramushro wtih B-25's in AE
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 Attu. High-explosive bombs were also loaded on the aircraft. Six B-24 Liberator bombers from the 21st Bombardment Squadron on Shemya were scheduled to join them, however they were diverted to attack Japanese transport ships spotted by a Navy PBY aircrew. The B-25s reached Paramushiro, which they found completely socked in by clouds. Using time/distance calculations they dropped their 500-pound bombs though the clouds on what they believed were the Japanese installations, then headed back to Alexi Point and landed after nine and a half-hour, 1,000-mile flight. At the time, it was the longest B-25 Mitchell mission of the war. Meanwhile, the B-24 Liberators had attacked the transports but failed to achieve any hits. One Liberator was hit by anti-aircraft fire from the ships and managed to make a wheels-up landing on Shemya.
