Research, Development, Test and Evaluation Unmet Needs Act of 2023

S 2455 requires the U.S. Department of Defense to submit an annual report to Congress within 10 days of the President's budget submission. The report must detail unfunded defense research, development, test, and evaluation priorities - including their objectives, required funding amounts, and program identifiers - ranked by urgency. It excludes priorities already covered in other existing reports. This law creates a new reporting mechanism under 10 U.S.C. § 222e to increase transparency about defense R&D funding gaps.
