Why was the ENIAC created?

In 1946, Mauchly and Eckert developed the Electrical Numerical Integrator And Calculator (ENIAC). The American military sponsored this research because it needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy.
