Welcome to our summary of Turn the Ship Around!: A True Story of Turning Followers into Leaders by L. David Marquet. This powerful leadership narrative chronicles Marquet's experience as commander of the USS Santa Fe, a nuclear submarine with a history of poor performance. Instead of employing a traditional top-down, leader-follower command structure, Marquet sought to dismantle it. The book’s central purpose is to provide a real-world case study for creating a 'leader-leader' model, empowering every crew member to take control and make decisions, thereby fostering a culture of engagement and excellence.
Part 1: The Problem & The Pain
I walked onto the USS Santa Fe with the weight of expectation on my shoulders and a year of training for a different submarine class in my head. The ship I was supposed to command, the USS Olympia, was one of the best. The Santa Fe, my new assignment, was the worst. The absolute bottom of the fleet. You could feel it in the air, a palpable sense of resignation that clung to the steel bulkheads like a damp chill. It wasn’t a ship; it was a morgue with a nuclear reactor. The crew’s posture told the whole story: slumped shoulders, averted eyes, a quiet compliance that screamed disengagement. They were good men, but they were trapped in a system that had beaten the initiative out of them. They were cogs in a machine, waiting for the master cog—me—to tell them which way to turn. This was the Leader-Follower model in its most diseased form, and I, its newest captain, was meant to be its cure. I thought my job was to be the smartest guy in the room, to give the best orders, to drag this crew kicking and screaming toward competence. I was wrong. Terribly wrong. The system wasn't just inefficient; it was dangerous. My epiphany didn't come from a flash of strategic brilliance. It came from a moment of my own foolishness. We were running a drill, a simulation to test our readiness. I wanted to see how the team would react under my command. I decided we'd use a novel propulsion mode, something the crew wouldn't expect. “Ahead two-thirds,” I ordered the Officer of the Deck, a bright, eager young officer. His eyes met mine, a flicker of something I couldn't read passing through them. “Ahead two-thirds,” he repeated, his voice crisp, turning to the helmsman to relay the command. The helmsman’s hands moved toward the controls. And in that frozen second, my stomach dropped. A cold dread washed over me. On this class of submarine, a Los Angeles-class fast-attack, there was no “ahead two-thirds” setting for the electric propulsion motor we were simulating. It was a physical impossibility. The order was nonsensical. It was like ordering a driver to put a car in ‘fifth-and-a-half’ gear. Yet my highly-trained officer, a man I was entrusting with the safety of 134 souls and a billion-dollar nuclear vessel, was about to execute an impossible order. He was about to try to do it because I, the Captain, had said so. I lunged for the microphone. “Belay that order!” The silence that followed was heavy, thick with unspoken questions. In that moment, I saw the truth with sickening clarity. I had a crew of followers. They would follow me right off a cliff, as long as the order was given with authority. My brilliance, my expertise, my perfectly crafted commands—none of it mattered. In fact, it was the problem. I was the problem. The model itself was the problem. We had created a system that valued obedience over thinking, a system that actively discouraged intellectual engagement from the people closest to the controls. We had 135 men on that submarine, but we were only using one brain: mine. And my brain, as I had just proven, was fallible. We weren't just underperforming; we were fragile. One bad order, one moment of inattention from the top, and we were done for. That night, I didn't sleep. I paced my small stateroom, the hum of the ship a constant reminder of the dormant power, both mechanical and human, that surrounded me. The goal could no longer be to turn this crew into better followers. The goal had to be to turn them into leaders. Every single one of them. My new job wasn't to have all the answers. It was to create an environment where the answers could emerge from anywhere, from anyone. The goal was to unleash the intellectual horsepower of 135 minds, not just one. It was a terrifying prospect. It meant turning 200 years of naval tradition on its head. It meant I had to stop giving orders. It meant I had to turn the ship around, in every sense of the word.
Pillar 1: Giving Control, Not Taking It
The path from Leader-Follower to Leader-Leader is not paved with rousing speeches. It’s built, brick by brick, with changes in behavior. We couldn’t just think our way to a new reality; we had to act our way into new thinking. The first, most deeply embedded obstacle was the very language of the ship. Our vocabulary was the genetic code of the Leader-Follower hierarchy. It was a stream of questions flowing up the chain of command—'Request permission to…?', 'What should I do about…?', 'Is it okay if…?'—and a stream of orders flowing down. This code perpetuated passivity. It placed all the ownership, all the thinking, at the top. To change the culture, we had to change the code. I didn’t want permission-askers; I wanted intention-staters. So, we outlawed the phrase 'Request permission to…'. We banned it. In its place, we instituted a new mechanism, a simple phrase that would become the cornerstone of our entire transformation: 'I intend to…'. The first time I heard it, it was awkward. A young sailor, standing watch in the control room, needed to submerge the ship. Under the old way, he would have looked to his supervisor, who would have looked to the Officer of the Deck, who would have looked to me. A chain of permissions. Instead, after a long, hesitant pause, he looked at his console, then at his supervisor, and said, 'Sir, I intend to submerge the ship.' The silence was deafening. Every eye turned to me. The old impulse roared in my mind: Just say 'very well,' just give the permission, keep things moving. But that would have defeated the entire purpose. I had to resist the urge to provide the solution, to give the comforting approval. My job was no longer to approve actions but to ensure the thinking behind them was sound. I looked at the sailor. 'Okay. What are you seeing that makes you think that’s the right thing to do right now? What have you considered?' I was thinking out loud, verbalizing my own decision-making process to make it transparent, to teach. He walked me through the checklist, the contacts on the surface, the ship's depth. His voice grew more confident with each data point. He wasn't just following a procedure; he was owning the decision. He had the information. He was the one who should have the authority. When he finished, he didn't need my permission. He knew it was the right call. All I said was, 'Very well.' The ownership had shifted. It was a small moment, a tiny linguistic change, but the deck plates beneath my feet felt like they had shifted. This was acting our way to new thinking. It was uncomfortable. For me, it was a constant battle against my own instincts. My brain, trained for years to be the problem-solver, wanted to jump in. When an officer came to me with an issue, my first impulse was to provide the answer. It’s a satisfying feeling, being the hero who fixes things. But every time I gave a solution, I was robbing my officers of a chance to build their own problem-solving muscles. I was reinforcing the old model. I had to learn to say, 'That’s a tough one. What do you think we should do?' It was maddeningly inefficient at first. Conversations took longer. Decisions felt slower. But we weren't just solving the immediate problem; we were building a capacity to solve all future problems. We also had to dismantle the systems that signaled a lack of trust. We eliminated top-down monitoring systems, the endless check-up reports and brief-backs that served no purpose other than for senior leaders to feel in control. Instead of me checking on them, we empowered the crew to self-monitor and report anomalies. We were giving control, not taking it. And in giving it, we were paradoxically gaining more control over the ship's ultimate success than ever before. We weren't just changing what people did; we were changing who they were. They were no longer 'the guys who submerge the ship.' They were 'the leaders responsible for safely submerging the ship.'
Pillar 2: Building Competence
Handing over the keys to a high-performance sports car to someone who has never driven is not empowerment; it’s an invitation to a catastrophe. Pushing control down the chain of command is exhilarating, but there is a terrifying corollary: control without competence is chaos. Empowering a crew that isn't ready to make good decisions would have been the fastest way to sink the Santa Fe. Alongside giving control, we had to relentlessly and deliberately build competence, both technical and personal. This wasn't about more classroom training or thicker procedure manuals. This was about fostering a culture where learning was constant, continuous, and embedded in every single action. The first casualty of this new approach was the traditional military briefing. Briefings are a fundamentally passive activity. One person stands at the front of the room and dispenses information, while everyone else sits, nods, and tries to stay awake. Information is transmitted, but competence is not guaranteed. It's a system designed for compliance, not comprehension. So, we killed the brief. We replaced it with a process we called 'certification.' Before any significant evolution—getting underway, firing a torpedo, starting up the reactor—the officer in charge would have to 'certify' to me that his team was ready. This wasn't a one-way download of information. It was a two-way accountability session. I would pepper them with questions. Not 'Did you brief your team?' but 'How do you know your sonar operator is ready? What was the hardest question he asked you? Show me that you've thought through the contingencies. Convince me that you are prepared to do this safely and effectively.' The focus shifted from 'Did we talk about it?' to 'Are we truly competent?' It forced leaders to engage deeply with their teams, to ensure real understanding, not just passive reception. It was about taking deliberate action, moving from a reactive posture of compliance to a proactive stance of thoughtful execution. This philosophy extended to how we defined tasks. The old way was to specify methods. 'Go to compartment X, turn valve Y, and report back.' It’s clean, it’s simple, and it requires zero thought from the person executing the task. The new way was to specify goals, not methods. We would define the 'what' and the 'why,' but we would empower the team to determine the 'how.' I remember one maintenance job on a seawater pump that typically took eight hours, requiring a partial shutdown of certain systems. Instead of handing the Petty Officer a 12-page procedure, the engineering chief said, 'We need to get this pump serviced with minimal operational impact. The goal is to have it back online before the evening watch. I trust you and your team to figure out the best way to do it.' The team huddled. They looked at the system diagrams. They walked through the space. And they came back with a completely new sequence that allowed them to isolate the pump without the broader system shutdown. They got the job done in four hours. They invented a better method because we didn't give them one. They were more competent than the procedure manual. We had to create an environment where learning was a core activity, happening everywhere, all the time. We dissected errors, not to assign blame, but to extract the maximum possible learning. We celebrated procedural non-compliance when it led to a better outcome, and then we worked to change the procedure. Competence wasn't a static attribute you achieved in a schoolhouse; it was a dynamic state of readiness we had to cultivate every single day. Control and competence were two pistons in the same engine. One couldn't move without the other. By building competence, we weren't just making our sailors better technicians; we were making them worthy of the control we were determined to give them.
Pillar 3: The Clarity of Purpose
Imagine giving a team of brilliant, competent people full control over their work, but failing to tell them what the company is trying to achieve. You'd get a flurry of incredible, well-executed activity, all pulling in different directions. You’d get chaos. Control and Competence were the engine of the Santa Fe, but Clarity was the rudder. It provided the purpose and the guiding principles that allowed 135 individual leaders to make decentralized decisions that were aligned with our overall goals. Without clarity, empowerment is just anarchy. The most profound shift we made in this pillar was moving our focus from avoiding errors to achieving excellence. On a nuclear submarine, the institutional mindset is, understandably, dominated by error avoidance. 'Don't screw up' is the unspoken mantra. The problem is, 'Don't screw up' is a terrible goal. It’s passive. It’s defensive. It inspires timidity, not greatness. You can't rally a team around 'not failing.' We needed a proactive, affirmative goal. Our new goal became 'Achieve operational excellence.' This wasn't just semantic fluff. It fundamentally changed how we viewed our work. Instead of asking, 'How do we avoid mistakes?' we started asking, 'How could we do this even better? What does a perfect evolution look like?' This pursuit of excellence created the energy and motivation that error avoidance never could. Foundational to this clarity was trust. You cannot have a high-performing, Leader-Leader organization without a bedrock of psychological safety. People needed to know they could speak up, question authority, admit mistakes, and try new things without fear of punishment or humiliation. My 'impossible order' epiphany had taught me that our old system encouraged people to hide uncertainty. We had to reverse that. We had to make it safe to be wrong. We did this by taking care of our people, by seeing them as human beings, not just cogs. When someone made a mistake, our first question wasn't 'Who did this?' but 'What can we learn from this, and how can we make the system better?' This built the trust necessary for the honesty and risk-taking that excellence requires. To help guide decentralized decisions, we established a set of simple, memorable guiding principles. These weren't pages of regulations; they were short, powerful heuristics. 'Think out loud.' 'Embrace the inspectors.' 'Take deliberate action.' 'We learn.' These principles became our common language, a compass that any crew member could use to orient their decisions when I wasn't there. They provided clarity on how we would pursue our goal of excellence. We also needed a powerful 'why.' Why did this matter? We found it by connecting our work to a larger purpose. We used the legacy of the US Submarine Force—a history of courage, sacrifice, and innovation—as a source of inspiration. We weren't just turning wrenches and standing watch; we were stewards of a proud legacy, protecting our country. This gave our daily grind a sense of meaning that transcended the steel hull. Finally, we learned to use immediate recognition to reinforce the behaviors we wanted. When a sailor used 'I intend to...' perfectly, or when a junior officer certified his team with exceptional rigor, we celebrated it on the spot. We didn't wait for the quarterly awards ceremony. A public 'well done' over the ship's announcement system, acknowledging a specific leader-leader action, was more powerful than any medal. It sent a clear signal to the entire crew: this is what we value. This is what excellence looks like. Control gave them the 'how.' Competence gave them the ability. But Clarity gave them the 'why.' It was the shared consciousness that aligned all our efforts, turning 135 individual leaders into one cohesive, unstoppable team.
The Leader-Leader Legacy
Looking back, the transformation of the USS Santa Fe can be understood through a simple model I came to call the 'Ladder of Leadership.' When I arrived, my crew was on the lowest rung: 'Tell me what to do.' They were passive receivers of instructions. As we started implementing our changes, they slowly began to climb. First to 'I think…,' then to 'I recommend…,' and finally, to the rung that changed everything: 'I intend to…'. But we didn't stop there. The ultimate goal was to reach the top rungs: 'I have done…' and 'I have been doing…', where the team was so competent and so aligned with our goals that they were taking proactive, necessary action and simply reporting it. We reached that level. We went from the worst ship in the fleet to the best, earning the highest performance awards and setting records for retention and promotion. This wasn't a miracle. It was the result of a deliberate, replicable process. It was the result of the Leader-Leader model. It was the result of a simple, powerful formula: Control + Competence + Clarity. These are the three pillars of empowerment. Give people control over their own work. Ensure they have the competence to exercise that control effectively. And provide absolute clarity on the organization's goals and purpose. Take away any one of those pillars, and the structure collapses. Control without competence is chaos. Competence without control is frustrating and leads to disengagement. And both without clarity are a recipe for well-executed but misaligned work. The entire philosophy is underpinned by one core tenet: push authority to information. In the industrial age, leaders sat at the top of the pyramid because that's where the information was consolidated. In the information age, that model is obsolete. The people at the bottom, the ones at the pointy end of the stick, the ones with their hands on the controls and their eyes on the sonar screen—they have the most current, granular information. To deny them the authority to act on that information is to intentionally build inefficiency and fragility into your system. Our job as leaders is not to hoard authority and information, but to push it down, to marry it together at the lowest possible level. The ultimate proof of the Leader-Leader model's success wasn't the awards we won while I was in command. The ultimate proof came after I left. Under the old Leader-Follower model, a ship's performance craters when the 'heroic' leader departs. The crew, dependent on the leader for direction, is lost. But the Santa Fe continued to excel. It continued to win awards. It continued to promote its sailors into leadership positions at rates far exceeding the fleet average. We hadn't built a great ship that was dependent on a great captain. We had built a great crew that had learned to lead itself. We hadn't just turned a ship around; we had created an enduring legacy of leadership. We had created a machine for building leaders. That is the only victory that truly matters.
In the end, Marquet’s revolutionary approach achieved unprecedented success. The critical resolution is not just that the USS Santa Fe’s performance improved, but that it transformed from the worst-performing submarine in its fleet to the very best. This dramatic turnaround culminated in record-breaking retention and inspection scores. The crew, once disengaged, became a cohesive team of leaders, with a remarkable number of officers later being selected for their own commands—a true testament to the model's lasting impact. The book's primary strength is its documentation of specific, actionable mechanisms for achieving this cultural shift, making it an essential guide for leaders seeking to unlock their team's full potential.
