This volume chronicles aerial warfare in the South Pacific from December 1941 until March 1942, during which air operations by both sides became a daily occurrence. As Imperial Japanese Navy flying boats and land-based bombers penetrated over vast distances, a few under-strength squadrons of the Royal Australian Air Force put up a spirited fight. However it was the supreme power of aircraft carriers that had the biggest impact. Four Japanese fleet carriers facilitated the capture of Rabaul over a devastating four-day period in January 1942. The following month, the USS Lexington’s fighter squadron VF-3 scored one of the most one-sided victories of the entire Pacific War. By March 1942 the Japanese had landed on mainland New Guinea, and the scene was set for a race to control Port Moresby.
