History
Fort Casey was named for Brigadier General Thomas Lincoln Casey, U.S. Army Chief of Engineers.[ Designed as part of the massive modernization program of U.S. seacoast fortifications initiated by the Endicott Board, construction on Fort Casey began in 1897. In 1901, the big guns on disappearing carriages, which could be raised out of their protective emplacements so that the guns were exposed only long enough to fire, became active. However, the fort's batteries became obsolete almost as soon as their construction was completed.
The invention of the airplane in 1903, and the subsequent development of military aircraft made the fort vulnerable to air attack. In addition, the development of battleships designed with increasingly accurate weaponry transformed the static strategies of the nineteenth century into the more mobile attack systems of the twentieth century.
