Project 7734 was a secret project by the U.S. Military to defend the planet against alien incursion by any means necessary. Led by General Sam Lane, the group's distrust of the newly-restored Kryptonian civilization on the planet New Krypton caused them to begin work on an preemptive attack. This attack led to the destruction of New Krypton, as well as a full-fledged war between the Kryptonian and Human militaries. (Comic storylines: Superman: New Krypton, The Last Stand of New Krypton, War of the Supermen)
