9USS Yorktown (CV-5) was the US Navy's first battle-worthy, purpose-built aircraft carrier. Her crew, already accustomed to wartime conditions by maintaining Neutrality Patrols during 1941 in the Atlantic, quickly adapted to the Pacific Theater, having been dispatched there immediately after Pearl Harbor. First at Coral Sea, then at Midway, Yorktown's flyers blunted the sword of Japanese aggression. The men flying from her decks were instrumental in turning the tide of WWII in the Pacific. This volume explores Yorktown's construction, prewar and wartime activities through carefully researched photos, many of which have never before been published, which are reproduced in remarkable clarity. This clarity, and the large size of many of the photos, coupled with descriptive and informative captions, puts the reader on the deck of this historic warship throughout her history.
