During World War II, the U.S. military lost some 35,000 aircraft to enemy action, training incidents, typhoons, aircraft carrier deck mishaps, mechanical failures or just normal wear-and-tear where aircraft were scrapped and used for parts to keep others flying. Many just failed to return from their missions. To date, the 15,069 aircraft represented in this 3-volume set is information initially transferred from hand-written "Aircraft History Cards" and are the total number of U.S. Navy, Marine Corps and Coast Guard aircraft lost between 7 December 1941 and 15 August 1945, and lost outside the continental United States (CONUS). Volume I represents the information on any aircraft lost that was attached to the 197 different ships in the database. Given the thousands of hours that went into this effort, the author hopes that, as a 3-volume set of reference books, it provides assistance to others who are researching ship, squadron and aircraft histories.
