In compiling this Handbook of Armament as used on aircraft, no attempt has been made to treat the various subjects in an exhaustive technical manner. Full data of this description can be obtained from the various reference books issued by the War Department, of which there is a list embodied in this book. The principal idea has been to acquaint all interested, with the correct nomenclature in particular, and with the appearance, fundamental ideas, and theories relative to all articles of armament pertaining to airplanes as produced by the United States.
