Yes. That's why ENIAC was developed by the army--to generate tables.

WW II dramatically changed a great many areas of science and technology affecting many things in every day life, such as development of Saran Wrap as a protective film and molded plywood for furnishings. The pressure of war allowed the govt to throw big money to solve problems. Some solutions were found, some were failures and forgotten.
