The ENIAC was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory, but it's first use was in calculations for the hydrogen bomb.
The ENIAC used 160 kilowatts (160,000 watts).

ENIAC was designed and built in WW2 for the following purposes:Calculate new firing tables for existing artillery pieces in use where existing tables were found inadequateCalculate firing tables for new artillery piecesIt had to be able to do this much faster than the existing human computers then used for these tasks. However ENIAC was not operational until after the end of the war.
The ENIAC computer was finished in November, 1945.
