Institute for Defense Analysis

The Institute for Defense Analyses (IDA) is a US federally funded research and development centre (FFRDC) headquartered in Alexandria, Virginia. Founded in 1956, it serves the Office of the Secretary of Defense, the Joint Staff, and intelligence-community agencies through three centres: the Systems and Analyses Center, the Center for Communications and Computing, and the Science and Technology Policy Institute.

UAP-Related Role

IDA's analytical work has intersected with UAP research primarily through Cold War-era threat-assessment studies and modern advanced-technology reviews. In the 1960s, IDA analysts contributed to Department of Defense evaluations of reported UAP encounters, particularly those with potential strategic-threat implications. Contemporary IDA work on hypersonic threats, adversary stealth capabilities, and advanced propulsion frameworks overlaps with topics examined by AARO and the intelligence community.

Significance

As an FFRDC, IDA produces authoritative but often classified analyses consumed by senior defence officials. Its reporting culture makes its records an important, though limited, reference for US UAP policy analysis. IDA-adjacent analysts have contributed to public discussions of UAP threat assessment since 2021.
