Marillyn Hewson Cut F-35 Unit Cost 26% — And Still Didn’t Fully Solve the Problem
The Lockheed Martin CEO Who Drove One of the Most Impressive Cost Reduction Trajectories in Defense Procurement History and Still Only Earns Three Kills Out of Five
From $108 Million to $80 Million Per Unit, a Direct Negotiation With the White House, and an Operational Availability Rate That Exposed the Limit of Cost Discipline Alone

The F-35 program is simultaneously the most expensive defense procurement project in American history and, under Marillyn Hewson’s stewardship, one of the most instructive cost reduction case studies in complex manufacturing program management. Hewson drove the unit cost of an F-35A from approximately $108 million in 2014 to $80 million in 2019 — a 26% reduction on one of the most technically complex production programs human beings have ever attempted. That is a genuine operational achievement. It is also incomplete. Because cheaper is not the same as better. And in complex systems management, the metric that actually matters most is not unit cost. It is operational availability — missions flown, aircraft ready, military capability delivered. Hewson moved the cost number. She didn’t fully move the availability number. That gap is the entire story of this forensic audit.
The Disease in the Program: When Cost Overruns Stop Being Failures and Start Being Forecasts
I have spent enough time inside large-scale manufacturing programs at Berkshire Hathaway and Illinois Tool Works to recognize the pathology that infected the F-35 before Hewson arrived. It is not unique to defense contracting. It occurs in any complex program — industrial, infrastructure, technology — where cost escalation is absorbed often enough that it stops triggering corrective action and starts being built into the baseline planning.
The F-35 program’s stagnation score was a 7 out of 10 on the corporate cancer scale when Hewson took the controls, and the disease was precisely this: cost growth normalization. A culture where cost escalation was expected, budgeted for, and absorbed as a structural feature rather than managed as a management failure. The operational discipline mechanisms that would detect and correct cost overruns had atrophied because nobody needed them. When everybody in a program expects costs to rise, nobody is structurally incentivized to hold them down. The budget absorbs the growth, the schedule absorbs the slip, and the disease compounds until someone decides that the normalization itself is the emergency.
I have seen this in industrial manufacturing programs that ran years over schedule and hundreds of millions over budget because the initial cost growth — tolerated in Year One — became the implicit permission structure for every subsequent overrun. The program team stopped asking whether costs were controllable and started asking how to explain the next increase. Hewson walked into a program that had been having that second conversation for years and forced the first one back onto the table.
The Real Betrayal: What Cost Growth Normalization Actually Costs the Customer
Here’s the part of this story that hits hardest when you audit it honestly. The customer’s actual need is not a low unit cost aircraft. The customer’s need is missions flown — operational squadrons at adequate readiness, available when the military requires them. Unit cost is a proxy metric, not the real metric. It is useful, it is trackable, it is reportable to Congress, and it is not the thing the Air Force, Navy, and Marine Corps actually need from a fifth-generation fighter platform.
When cost and schedule become the primary management focus in a complex weapons system program, operational performance metrics — reliability rates, maintenance costs, availability for deployment — can drift without triggering the same level of program leadership attention. That is exactly what happened in the F-35 program. The cost discipline Hewson applied was real and consequential. The operational availability rates for F-35 squadrons remained below targets throughout her tenure, which means the aircraft that cost less to build also cost too much to maintain at adequate readiness. You cannot declare a cost reduction victory on a product the customer cannot reliably use at the tempo the mission requires.
This is the manufacturing quality lesson I have applied in every industrial context I have worked in: unit cost reduction that degrades operational performance is not cost reduction. It is cost transfer — moving the expense from the acquisition line to the sustainment line where it is less visible and more painful. The total cost of ownership is the honest number, and Hewson’s tenure improved one component of it while leaving another component unresolved.
What Hewson Got Right: Three Operational Decisions Worth Studying Closely
The per-unit cost reduction trajectory is the headline and it deserves respect. Driving a 26% unit cost reduction on a program of the F-35’s technical complexity — thousands of components, dozens of international suppliers, three service variants with different performance specifications — is not a procurement efficiency exercise. It required sustained operational discipline applied across learning curve economics, supply chain negotiation, and lot-size leverage over a multi-year period. At the scale and complexity of the F-35, a 26% unit cost reduction represents billions of dollars of savings on future production lots. That is real money, real discipline, and a real operational achievement that most program managers in the defense industry did not match on comparable programs during the same period.

The direct negotiation with the Trump administration over F-35 pricing is the decision I find most operationally interesting. Most defense contractor CEOs in that political environment would have played the game defensively — managed the relationship, absorbed the political pressure, avoided the confrontation. Hewson engaged directly and publicly, forcing a price transparency conversation that most procurement relationships actively avoid. The outcome was a lower unit cost negotiation rather than a procurement confrontation. She converted external political pressure into an internal cost discipline lever. That is a specific kind of operational judo — using the force of an external threat to accelerate an internal improvement that the organization was not moving toward fast enough on its own. I have used exactly this mechanism in manufacturing turnarounds when the external pressure of a customer ultimatum or competitive bid was the only force capable of driving the internal cost structure conversation that the organization had been avoiding. The external pressure is not the enemy. Deployed correctly, it is the catalyst.
The supply chain sovereignty investment — Lockheed’s deliberate investment in supplier capability to reduce dependence on sole-source suppliers with pricing leverage — is the structural cost reduction move that most supply chain strategies miss. Negotiation-level savings are recoverable. Structural dependency on a sole-source supplier is a permanent pricing liability. Hewson invested in building alternative supplier capability specifically to eliminate the structural leverage that monopoly suppliers held over the program’s cost architecture. That is not a procurement tactic. It is a supply chain architecture decision that produces compounding cost benefits across every subsequent production lot.

The Murder Board: Three Kills Out of Five and the Availability Problem That Explains the Gap
Three kills out of five. Hewson earned genuine marks for what she accomplished on cost. The murder board is equally genuine about what she didn’t accomplish on performance, and the gap between those two scorecards is the most important lesson in this audit.
The F-35’s reliability and availability rates for operational squadrons remained below targets throughout Hewson’s tenure. The maintenance architecture produced aircraft that were too expensive to sustain at adequate operational readiness rates. A lower-cost aircraft that cannot maintain adequate mission-ready status is a partial achievement — and in a weapons system context, a partial achievement means squadrons that cannot fly at the operational tempo the mission requires. That is not a procurement abstraction. It is a military capability gap measured in sortie rates and deployment readiness.
The deeper structural lesson is about metric selection in complex program management. When cost and schedule are the primary accountability metrics, they tend to remain the primary decision filters even when operational performance is degrading. The program leadership optimizes what it is measured on. If availability is not an equally weighted accountability metric — not a secondary concern but a co-equal constraint alongside cost — it will drift. Hewson’s achievement on cost was real. The failure to match it with equivalent improvement on availability reflects a program management architecture that had not yet fully answered the question of what the customer actually needed the aircraft to do.

Frequently Asked Questions
How did Marillyn Hewson reduce the F-35 unit cost by 26%?
The cost reduction trajectory combined three mechanisms deployed simultaneously over multiple production lots. Learning curve economics — the natural cost reduction that occurs as manufacturing processes mature and production volumes increase — provided the baseline improvement. Systematic supply chain negotiation as lot sizes increased allowed Lockheed to extract better pricing from suppliers who were themselves moving down their own learning curves. And the deliberate investment in alternative supplier capability eliminated sole-source pricing leverage that had been a structural cost driver. The direct negotiation with the Trump administration added a political accountability layer that accelerated the cost discipline already underway. None of these mechanisms alone produced 26%. The combination, sustained over five years of production lots, did.
What is cost growth normalization and why is it so dangerous in complex programs?
Cost growth normalization occurs when cost escalation in a program is absorbed often enough that it stops being treated as a management failure and starts being treated as a structural feature — expected, budgeted for, and planned around. The danger is that it atrophies the operational discipline mechanisms designed to detect and correct cost overruns. Once the program culture accepts that costs will rise, no one is structurally incentivized to hold them down. The normalization compounds: each absorbed overrun becomes implicit permission for the next one. I have seen this pattern in industrial manufacturing programs where the first schedule slip became the template for every subsequent estimate. The cure always requires someone at the top of the program hierarchy to declare that normalization is the emergency — not the individual overruns, but the culture that makes them invisible.
Why did Hewson only earn three kills out of five despite the cost reduction achievement?
Because cheaper is not the same as better, and in a complex weapons system, the metric that matters most is operational availability — aircraft ready to fly missions at the tempo the military requires. The F-35’s reliability and availability rates for operational squadrons remained below targets throughout Hewson’s tenure. A lower-cost aircraft that cannot maintain adequate readiness is a cost transfer, not a cost reduction: the expense moves from the acquisition line to the sustainment and readiness line where it is less visible and more operationally damaging. The murder board is real and it is material. Hewson earned marks for cost discipline. She did not earn equivalent marks for solving the operational performance problem the customer actually needed solved.
What can manufacturers learn from Hewson’s supply chain sovereignty investment?
The supply chain sovereignty lesson is transferable to any manufacturing context with sole-source supplier dependencies. Negotiation-level savings are recoverable by the supplier on the next contract cycle. Structural dependency on a supplier with no qualified alternative is a permanent pricing liability that compounds with every production lot. Hewson’s investment in building alternative supplier capability — expensive in the short term, structurally decisive in the long term — is the correct response to that dependency. The question every manufacturing operator needs to answer about their own supply chain is not what price they negotiated last quarter but how many of their critical inputs have no qualified alternative source. Each sole-source dependency on that list is a cost growth normalization risk embedded in the supply chain architecture.
What is the real metric in complex systems management and why does it matter?
The real metric is the output the customer actually needs, not the proxy metric that is easiest to track and report. In a weapons system, the real metric is missions flown and operational readiness — not unit cost. In a manufacturing context, the real metric is customer-experienced quality and on-time delivery — not internal production efficiency. In a service business, the real metric is customer outcome — not billable hours. The F-35 program optimized aggressively on cost and schedule, which are the metrics that are reportable to Congress and trackable in procurement contracts. Operational availability, which is the metric the Air Force actually needs, improved more slowly. The lesson: define the real metric first, then build the management accountability architecture around it. Proxy metrics are useful only when they reliably predict the real metric. When they diverge, the proxy metric wins every time — and the customer pays the difference.

Episode: Forensic Audit: Marillyn Hewson and the F-35 Cost Reduction That Proves Cheaper Is Not the Same as Better
Key Insight: A 26% unit cost reduction on the most complex manufacturing program in history is a genuine achievement — and an incomplete one, because in complex systems management, availability is the metric that actually matters most and cost reduction is only the beginning.
Your assignment this week: identify the proxy metric your organization is optimizing most aggressively and ask whether it reliably predicts the real metric your customer actually needs. Pull the last four quarters of your primary operational KPI alongside the last four quarters of your customer-experienced outcome metric — delivery performance, quality rate, availability, or whatever the real output is for your context. If those two lines are diverging, you have a cost-growth-normalization-style problem in your metric architecture. You are optimizing what is easy to track at the expense of what the customer actually needs. Visit toddhagopian.com for the complete complex program management diagnostic framework. Are you measuring what’s convenient — or what actually matters to the customer paying the bill?
