Office of Naval Research (ONR) The Department of Defense National Defense Science and Engineering Graduate Fellowship (DoD NDSEG) is a fellowship awarded annually to U.S. citizens pursuing doctoral degrees in science and engineering disciplines.

The NDSEG Fellowship lasts for three years, paying for full tuition and all mandatory fees in that period.

[4][5] An act of Congress established the NDSEG Fellowship in 1989, requiring that fellows be selected "solely on the basis of academic ability.

Applicants are required to submit a 4-page single-spaced research proposal, with a maximum of one page for cited work.

The fellowship has previously been managed by the American Society for Engineering Education (ASEE),[9][16] STI-TEC,[17] and Systems Plus.
