Japanese naval aviation began the war with an elite cadre and an inadequate reserve and training system for replacing it. As experienced formations suffered losses, carrier air groups supplied leaders and pilots to sustain land-based units into spring 1943. This kept those units effective temporarily while depleting another part of the force. By late 1943, mounting replacement demands coincided with less training time and less fuel, leaving increasingly inexperienced crews to enter combat. Aircraft that offered little protection to their crews compounded the difficulty of preserving experienced personnel.
