Major Defense Acquisition Program (MDAP)

A Major Defense Acquisition Program (MDAP) is a Department of Defense acquisition program that exceeds the statutory dollar thresholds established in 10 U.S.C. § 4201, specifically, research, development, test, and evaluation (RDT&E) costs exceeding $525M or procurement costs exceeding $3.065B in FY2020 constant dollars, triggering enhanced oversight, congressional reporting, and independent cost and technical assessments.

What is a Major Defense Acquisition Program?

MDAP designation triggers the most rigorous tier of defense acquisition oversight. When a program is designated as an MDAP, it must: receive OSD-level Milestone Decision Authority for milestone reviews; have an independent cost estimate prepared by the Cost Assessment and Program Evaluation (CAPE) office; undergo independent technical risk assessments; report annually to Congress on cost, schedule, and performance; and comply with the full suite of 5000 Series acquisition requirements.

The Nunn-McCurdy Act (10 U.S.C. § 4371) established specific cost breach thresholds for MDAPs: a "significant cost growth threshold" (25% increase in program unit cost over the original baseline or 10% increase over the most recently approved baseline) triggers mandatory congressional notification; a "critical cost growth threshold" (50% increase over the original baseline or 25% over the current baseline) requires the program to be restructured or terminated unless the Secretary of Defense certifies it is essential to national security.

Nunn-McCurdy breaches are major events in defense contracting. When a breach occurs, the certification process requires Congressional notification, an independent cost estimate, an independent technical assessment, a plan to control costs, and the Secretary of Defense's personal attestation. Programs that breach the critical threshold and cannot be certified are legally required to be terminated, a significant outcome that has ended several major programs.

The Most notable MDAPs in history include the F-35 Joint Strike Fighter, Virginia-class submarine, DDG-51 Arleigh Burke destroyer, Army Future Vertical Lift programs, and the Ground-Based Strategic Deterrent (GBSD). These programs represent tens to hundreds of billions in total cost and represent the pinnacle of defense acquisition complexity.

Why MDAPs matter for government contractors

MDAP designation means a program has the largest budgets, longest timelines, and highest stakes in the defense acquisition portfolio. Prime contractor positions on MDAPs anchor the defense industrial base's major business units, winning MDAP EMD or production contracts is a career-defining achievement in defense contracting.

Example

The F-35 Joint Strike Fighter is the largest MDAP in history. Originally estimated at approximately $200B total program cost, current estimates exceed $400B through production, a multi-decade MDAP that has experienced multiple Nunn-McCurdy significant cost breaches. Lockheed Martin as the prime contractor manages 1,500+ suppliers across the industrial base. The program's complexity, scale, and congressional visibility make it the defining example of MDAP management challenges.

Frequently Asked Questions

How many MDAPs are currently active?

The Pentagon's Selected Acquisition Reports (SARs), submitted to Congress annually, list all active MDAPs. As of recent reporting, there are approximately 80-100 active MDAPs across all DoD components at any given time, with combined current estimate total program costs in the trillions of dollars.

What is a Selected Acquisition Report (SAR)?

A SAR is the annual Congressionally mandated cost, schedule, and performance report that every MDAP must submit to Congress. SARs are publicly available and provide detailed information on program costs, milestone achievements, and changes from prior year baselines, making them valuable market intelligence for contractors tracking specific programs.

Can an MDAP be re-designated as a non-MDAP?

Yes, if a program is restructured significantly (scope reduction, quantity reduction) such that its estimated costs fall below the MDAP thresholds, the program office may seek re-designation. However, re-designation requires OSD approval and is relatively rare once a program is established as an MDAP.

What is the relationship between MDAPs and the defense budget?

MDAPs are funded through the President's Budget request, with RDT&E funding in the RDT&E budget lines and procurement funding in Procurement budget lines. Congress reviews MDAPs individually during the authorization and appropriations process, often adjusting quantities, schedules, and funding profiles. MDAP budget visibility means these programs are subject to intense congressional and public scrutiny.
