Weapon Systems Annual Assessment: Requiring Mature Technologies Could Enable Shift to Rapid Delivery , July 2 , 2026
From the report: "The Department of Defense (DOD) continues to struggle to deliver technologies quickly and within budget. Since its last annual assessment, GAO found:
• Programs are delaying interim events and milestones for some of the costliest major defense acquisition programs (MDAP).
• DOD has increased its use of the middle tier of acquisition (MTA) rapid prototyping and fielding pathways—intended to be completed in 5 years.
• Some programs began on the MTA pathway with technologies that require more time to develop, hindering timely delivery of essential capabilities.
• Programs do not consistently follow leading practices for product development that could help DOD achieve its stated goals.
Schedule delays persisted across MDAPs, signaling overly optimistic time frames. The overall average time frame to deliver a capability increased this year to over 12 years. Further, several MDAPs have not set new delivery dates or are delaying critical interim milestones. By keeping delivery dates static, these programs raise questions about how realistic their estimates are. This means the 12-year average will likely increase in the future."
