The alignment is from left to right so that an American Element is equal to a Japanese Shotai. As you can see there is not always an equivalent. The Japanese Army Air Force adds the Air Brigade and Air Division in between their equivalent of the American Group and Air Force. Note too that the IJAA has no Chutai while the IJNA does.
The numbers of planes is an ideal number as it existed on paper. In real life in the field there were any number of conditions that had an impact on those numbers. On very rare occasion there may have been more planes available for a mission than pilots. Most often the opposite was true, pilots out-numbered the planes. The reasons were varied. Early in the war the combat planes that had been in the Pacific when the war started wore out before replacements were available. When the war in the Pacific had started America's resources were dedicated to the war in Europe. The forces in the Pacific were expected to just hold on until America could win in Europe or until it could bring it's production capacity up to the levels needed to supply all the combat theaters. What changed that was Guadalcanal. When it was discovered that the Japanese were building an airfield on Guadalcanal the government had to act. This forced America to move over to offense before it was ready. This caused extensive wear-and-tear on the planes as flying in those tropical conditions was very hard on them. They broke down or were shot down so that missions were basically made up of what- ever planes were capable of flying. The one unit that did not change was the Element. It was essential for survival that all fighter pilots flew in pairs. A squadron might only have 6 planes ready to fly but the Element was always 2. If there was an odd number of planes available then you found someone who's wingman was unavailable and you paired up with him, but you didn't fly alone.
As the war progressed and second generation fighters started to appear the supply problem diminished but didn't disappear. There were other reasons planes might be unavailable. Planes crashed, were shot up, were damaged in collisions, or simply had some part break or wear out. Maintenance crews did an incredible job of patching and repairing but parts were often in short supply.
The thing to remember is the American policy of flying in pairs and the tactics devised to exploit the use of 2 man teams combined to be one of the main reasons why the Allies were able to establish air supremacy in the Pacific by late 1943. |
