Morison, an Admiral himself by 1945, and a shrewd observer of Naval tactics, theorized that the better trained Japanese pilots including those using kamikaze tactics had been expended prior to Okinawa, and those trained for the battle there lacked time to gain commensurate skills with those available at the Battle of Lingayen.
