Office of Net Assessment

The Office of Net Assessment (ONA) is an agency of the United States Department of Defense created in 1973 by Richard Nixon to serve as the Pentagon's "internal think tank" that "looks 20 to 30 years into the military's future, often with the assistance of outside contractors, and produces reports on the results of its research". The office was temporarily abolished by Secretary of Defense Pete Hegseth in 2025, before being restored with a reduced budget.
