With the fall of Wuhan/Hubei province to the Japanese, the wartime capital of China had been pushed back to Chongqing, where an all-airwar campaign against targets in Sichuan province between the CAF and the IJAAF/IJNAF would rage for years in a cat and mouse game under the codenames ""Operation 100", "101" and "102"" IJA/IJN "joint-strike force" terror-bombing campaigns. Despite the general obsolescence of the Chinese fighter aircraft against the new Japanese "Schnellbombers", the CAF improvised, continuing to inflict casualties and losses against the Japanese raiders, culminating with the well-timed deployment of experimental air-burst bombs launched against the massive heavy bomber formations in August of 1940, and climaxing with the introduction of the most advanced fighter aircraft of the time: the Mitsubishi A6M "Zero", which gained almost complete air-supremacy with its unheard-of performance against the Chinese Air Force the following month, and would incredibly remain largely unheard-of almost a year and a half later when the allied air powers faced the scourge of the "Zero" fighter as the Imperial Japanese war machine expanded into the Pacific with the attack on Pearl Harbor.
