The Shipyard Worker Who Destroyed a $700 Million U.S. Navy Submarine Just to Leave Work Early
Some disasters begin with war, storms, mechanical failure, or enemy action.
This one began with a man who wanted to go home.
On May 23, 2012, the USS Miami, a nuclear-powered U.S. Navy attack submarine, was sitting in dry dock at Portsmouth Naval Shipyard in Kittery, Maine. The Los Angeles-class submarine was undergoing a major overhaul, the kind of long and complex maintenance period required to keep one of the world’s most advanced underwater vessels ready for service.
Inside the submarine, civilian workers were performing repair and maintenance tasks. Among them was Casey James Fury, a civilian painter and sandblaster working aboard the vessel.
According to court records and news reports, Fury wanted to leave work early. He was reportedly suffering from anxiety and had no vacation or sick leave left. Instead of speaking to a supervisor, asking for help, or simply enduring the shift, he made a decision that would become one of the most expensive acts of workplace arson in modern U.S. military history.
He used a lighter to set fire to a bag of rags on a bunk inside the submarine.
He expected a small fire.
What followed was a 12-hour inferno.
More than 100 firefighters battled the blaze. Seven people were hurt. Forward compartments of the submarine were badly damaged, including living areas, the command and control center, and the torpedo room. The nuclear propulsion area was not reached, and weapons had already been removed for maintenance, preventing an even greater disaster.
But the damage was still catastrophic.
At first, the U.S. Navy planned to repair the USS Miami. Initial estimates placed the damage and repair cost around $400 million to $450 million. Later assessments raised the projected repair bill to roughly $700 million. Under budget pressure, the Navy decided the submarine was too expensive to restore.
The USS Miami was decommissioned and sent to be scrapped.
One reckless act, committed to escape a work shift, effectively destroyed a nuclear-powered submarine.
It is a story that sounds almost impossible, but it is real. It is also a chilling reminder that in high-risk environments, one irresponsible decision can create consequences far beyond anything the person imagined.
What Was the USS Miami?
The USS Miami, officially USS Miami (SSN-755), was a Los Angeles-class nuclear-powered attack submarine. Commissioned in 1990, it was part of one of the U.S. Navy’s most important submarine classes.
Attack submarines like the USS Miami are designed for multiple missions. They can track enemy submarines, gather intelligence, support special operations, launch cruise missiles, protect carrier strike groups, and operate quietly across the world’s oceans.
These vessels are not ordinary ships. They are complex machines packed with advanced systems, weapons infrastructure, sonar equipment, communications technology, navigation equipment, and nuclear propulsion systems. Building and maintaining them requires enormous technical skill and money.
By 2012, the USS Miami had already served for more than two decades. It was undergoing a scheduled overhaul at Portsmouth Naval Shipyard, a key maintenance facility for U.S. Navy submarines.
The overhaul was supposed to extend its useful life.
Instead, the shipyard period became the beginning of the submarine’s end.
The Day of the Fire
On the day of the fire, the USS Miami was not at sea. It was in dry dock, surrounded by workers, equipment, scaffolding, tools, temporary systems, and repair materials. A submarine in overhaul is not in its normal operating condition. Panels may be removed. Compartments may be opened. Equipment may be disconnected. Materials used for repair may be stored nearby.
This kind of environment can be vulnerable to fire.
Fury was working in the torpedo room area, but he left his assigned work area and went to a stateroom or berthing compartment. There, he used a lighter to ignite rags or a plastic bag of rags placed on a bunk.
Then he left.
A small flame inside a submarine is not like a small flame in an open room. Submarines are enclosed, narrow, and packed with systems. Smoke, heat, and toxic fumes can spread through tight compartments. Access is difficult. Firefighters must enter through hatches and move through confined spaces while wearing heavy gear and carrying breathing equipment.
The fire quickly grew out of control.
What Fury may have thought would be a minor incident became a nightmare for everyone at the shipyard.
A 12-Hour Inferno
The USS Miami fire burned for roughly 12 hours.
More than 100 firefighters responded. They had to fight the blaze inside a steel vessel full of narrow passageways, intense heat, smoke, and dangerous conditions. Some responders described the fire as one of the worst they had ever seen.
Fighting a fire aboard a submarine is extremely difficult. Visibility can collapse to almost nothing. Heat can build rapidly. Firefighters may only be able to work for a few minutes at a time before retreating to change air bottles or recover. Moving through hatches and ladders while wearing gear is slow and exhausting.
Seven people were injured during the incident.
The fact that nobody died was partly luck and partly the result of the courage and skill of the firefighters who entered the burning submarine.
The fire damaged forward compartments, including living quarters, command and control areas, and the torpedo room. These are not small or cosmetic areas. They are central to the submarine’s operation.
The nuclear propulsion section at the rear of the submarine was not reached, and the submarine’s weapons had been removed because of the overhaul. That prevented the disaster from becoming even worse.
Still, the damage was devastating.
Why the Fire Caused So Much Damage
People sometimes ask how a bag of rags could destroy a nuclear submarine.
The answer is that a submarine is a highly complex enclosed environment. A fire inside it can damage far more than the exact spot where the flames began.
Heat can destroy wiring, electronics, insulation, piping, control systems, and sensitive equipment. Smoke can contaminate compartments. Firefighting water can damage systems. If the fire spreads through connected spaces, it can affect areas that were never directly touched by the original flame.
The USS Miami was also in overhaul, meaning normal shipboard conditions were disrupted. Maintenance work can introduce temporary materials, exposed areas, altered ventilation, and vulnerable workspaces.
Reports said the fire damaged or destroyed critical forward systems. That included areas tied to command, control, living space, and weapons handling.
Even if the hull itself survived, the cost of replacing internal systems became enormous. A submarine is not like a car where a damaged seat or dashboard can be replaced cheaply. Every system must meet strict military and safety standards. Work must be inspected, tested, certified, and integrated with the rest of the vessel.
That is why a small act of arson escalated into hundreds of millions of dollars in damage.
The First Explanation Was Wrong
Early reports initially suggested the fire may have started accidentally, possibly from an industrial vacuum cleaner. That explanation was later overturned by the investigation.
As investigators dug deeper, suspicion turned toward arson. Fury eventually admitted to setting the fire.
This is important because major industrial disasters often begin with confusion. Early information is incomplete. Investigators must examine burn patterns, witness accounts, materials, timelines, worker movements, and technical evidence.
In this case, the final conclusion changed the story completely.
What first looked like a tragic accident became a criminal act.
Who Was Casey James Fury?
Casey James Fury was a civilian shipyard worker from New Hampshire. He worked as a painter and sandblaster, a physically demanding job involving maintenance and repair work on Navy vessels.
He was in his mid-20s when the fire occurred. Reports described him as suffering from anxiety. His defense later argued that he had mental health struggles, including anxiety and depression.
But mental health struggles did not erase the seriousness of what he did.
According to reports, Fury said he wanted to go home and had no more vacation or sick leave available. Instead of seeking help or using proper channels, he created a dangerous fire inside a nuclear-powered military vessel.
Then, weeks after the first fire, he set another smaller fire outside the same submarine and later triggered a false alarm. That second fire caused little damage, but prosecutors considered it especially disturbing because Fury already knew the consequences of the first fire.
This pattern strengthened the case against him.
The Court Case and Sentence
Fury pleaded guilty to two counts of arson.
In March 2013, he was sentenced in federal court to 205 months in prison, which is a little over 17 years. He was also ordered to pay $400 million in restitution to the U.S. Navy.
The restitution amount was largely symbolic in practical terms. Prosecutors acknowledged that Fury would almost certainly never be able to repay anything close to that amount.
The judge weighed several factors: Fury’s mental health, his guilty plea, the danger to firefighters, the financial cost, the damage to the Navy, and the fact that he set a second fire after seeing the consequences of the first.
The sentence reflected both punishment and deterrence.
This was not treated as a small workplace mistake. It was a deliberate act that endangered lives and destroyed a major military asset.
From $450 Million to $700 Million
After the fire, the Navy initially planned to repair the USS Miami. Early estimates placed the cost at around $400 million to $450 million.
That figure alone was staggering.
But as engineers inspected the submarine more closely, the projected repair cost rose. Additional damage was found. More components needed replacement. Repairing the submarine became more complicated than expected.
Eventually, the estimated cost rose to about $700 million.
At that point, the Navy had to make a hard decision. Repairing the USS Miami would consume money and shipyard capacity that could be used for other maintenance priorities. The submarine was already more than 20 years old. Although it might have served for more years if repaired, the cost became difficult to justify under budget pressure.
So the Navy decided not to repair it.
The USS Miami was decommissioned and sent for disposal through the Navy’s nuclear ship recycling process.
A submarine that had survived decades of military service was effectively lost because of one fire started by one worker.
Why the Navy Scrapped the Submarine
Scrapping the USS Miami was not an easy decision.
A nuclear attack submarine is an extremely valuable asset. The U.S. Navy does not casually give one up. Submarines are expensive to build, difficult to replace, and strategically important.
But repairing a damaged submarine is not always practical.
The Navy had to consider:
The age of the submarine
The cost of repair
The time required to return it to service
The availability of shipyard workers and facilities
The impact on other maintenance schedules
The broader defense budget situation
The risk of hidden damage
The value of investing in newer vessels instead
When repair estimates rose to roughly $700 million, the Navy concluded that decommissioning was the more practical choice.
This made the fire even more consequential. It did not merely delay the submarine. It removed it permanently from service.
A National Security Loss
The USS Miami fire was not only a financial disaster. It was also a national security loss.
Attack submarines are among the most strategically useful assets in the U.S. Navy. They operate quietly, gather intelligence, track threats, and project power in ways surface ships cannot. Losing one reduces fleet capacity.
Even one submarine matters because submarine maintenance schedules are already complex. At any given time, some vessels are deployed, some are training, and others are in repair or overhaul. A submarine unexpectedly removed from service creates pressure across the fleet.
Navy officials recognized this at the time. Losing the USS Miami meant losing years of remaining operational life from a capable attack submarine.
The fire therefore affected more than one shipyard. It affected readiness, scheduling, and strategic planning.
That is why this incident is often remembered as one of the most costly acts of workplace sabotage in U.S. military history.
The Human Risk Behind the Dollar Figure
The $700 million number attracts attention, but the human risk matters even more.
Seven people were hurt. Firefighters entered a burning submarine under conditions that could easily have killed them. Smoke, heat, darkness, toxic fumes, narrow spaces, falling hazards, and limited escape routes made the operation extremely dangerous.
One firefighter described the experience as like fighting a fire inside a wood stove while climbing down the chimney. That image captures the horror of the situation better than any dollar amount.
The workers and firefighters did not choose the risk. Fury’s decision created it for them.
This is one of the most disturbing parts of the story. A person trying to escape a shift ended up forcing others into a life-threatening emergency.
The submarine was lost. Money was lost. But the fact that no one died was almost miraculous.
Why This Case Still Shocks People
The USS Miami fire continues to shock people because the motive seems so small compared with the damage.
People expect major sabotage to involve espionage, terrorism, war, revenge, or ideology. Here, the stated motive was wanting to leave work early.
That contrast is what makes the case unforgettable.
A moment of panic, immaturity, and reckless thinking led to the destruction of a military asset worth hundreds of millions of dollars. The scale of the consequence feels almost impossible to match with the scale of the motive.
But real disasters often work this way.
They do not always begin with grand plans. Sometimes they begin with shortcuts, stress, negligence, impulsive decisions, poor supervision, weak safety culture, or one person thinking, “It will not get that bad.”
Then it does.
Lessons for Industrial Safety
The USS Miami fire offers several important lessons for industrial safety.
First, high-risk environments need strong fire prevention controls. Shipyards, submarines, aircraft maintenance facilities, chemical plants, oil platforms, and power stations all contain hazards that can turn a small fire into a major disaster.
Second, worker mental health and stress matter. This does not excuse criminal behavior, but it shows that unmanaged anxiety, pressure, and lack of support can create dangerous situations.
Third, access control and supervision are critical. Workers in sensitive environments should not be able to create hazards unnoticed.
Fourth, emergency response planning must assume worst-case scenarios. The firefighters who battled the USS Miami fire faced a situation far beyond an ordinary workplace incident.
Fifth, safety culture must encourage people to speak up before they reach a breaking point. A worker who feels trapped, desperate, or unwell should have a safe way to report it without creating danger for others.
A safe workplace is not built only on rules. It is built on systems that prevent one person’s bad decision from becoming a national disaster.
The Mental Health Question
It is important to discuss Fury’s reported anxiety carefully.
Anxiety and depression are real conditions. Millions of people experience them without harming anyone. Mental health struggles do not automatically make someone dangerous, and they should not be used to stigmatize people.
At the same time, in this case, Fury’s anxiety was part of the court record and part of the explanation he gave for wanting to leave work.
The lesson is not that anxious workers are dangerous. The lesson is that workplaces handling dangerous systems need clear support mechanisms. If someone is overwhelmed, there must be a way to seek help before the situation becomes a crisis.
A worker should not feel that the only way to leave is to create an emergency.
But responsibility still matters. Fury had choices. He chose the most dangerous one.
The USS Miami’s Final Fate
After the Navy decided not to repair the submarine, the USS Miami went through decommissioning and inactivation.
A nuclear-powered submarine cannot simply be thrown away. It must be carefully processed. Nuclear fuel must be removed. Sensitive equipment must be handled properly. The vessel must be prepared for disposal under strict procedures.
Eventually, the submarine was sent to be cut up and recycled through the Navy’s ship-submarine recycling program.
That was the final chapter of a vessel that had once been part of the U.S. Navy’s undersea force.
The USS Miami did not sink in battle. It was not destroyed by an enemy torpedo. It was not lost in a storm. It was ended by arson during maintenance.
That is why the story remains so strange and tragic.
A Costly Example of Small Decisions With Huge Consequences
The USS Miami fire is often used as an example of disproportionate consequences.
The act was small in physical terms: a lighter, rags, a bunk, a flame.
The outcome was massive: a 12-hour fire, injured responders, hundreds of millions in damage, a lost submarine, a federal prison sentence, and a permanent mark in naval history.
This is what makes the story so memorable. It shows how dangerous environments magnify irresponsible behavior.
In an ordinary setting, a small fire may damage a room. Inside a nuclear submarine under overhaul, a small fire can destroy a strategic military asset.
Context matters.
Risk is not only about what someone does. It is about where they do it.
Why the Nuclear Detail Matters
Because the USS Miami was nuclear-powered, the story often sounds even more terrifying. However, reports make an important distinction: the fire did not reach the nuclear propulsion components at the rear of the submarine.
That matters.
The incident was catastrophic, but it was not a nuclear accident. The nuclear reactor area remained safe from the fire, and weapons had been removed during the overhaul.
Still, the word “nuclear” is not irrelevant. Nuclear submarines require strict safety standards because of the complexity and sensitivity of their systems. Any major fire aboard such a vessel is treated with extreme seriousness.
The fact that the nuclear systems were not reached is a relief.
The fact that a fire inside such a vessel happened at all is alarming.
Could This Have Been Prevented?
In hindsight, many disasters look preventable.
The USS Miami fire raises questions about supervision, access, fire safety, worker screening, mental health support, and emergency preparedness. The Navy and shipyard officials examined these issues after the incident.
But prevention is never only about catching one person. It is about building layers of protection.
Could flammable materials have been better controlled?
Could worker movement have been monitored more carefully?
Could there have been better detection systems during maintenance?
Could supervisors have recognized Fury’s distress earlier?
Could leave policies or support systems have provided a safer option?
Could shipyard fire protocols have reduced damage faster?
These are the kinds of questions high-reliability organizations must ask after a disaster.
Blaming one person is necessary legally, but it is not enough organizationally. The deeper goal is to prevent the next disaster.
Why This Story Still Goes Viral
The USS Miami fire regularly resurfaces online because it has all the elements of a shocking historical story:
A nuclear submarine
A young civilian worker
A tiny fire
A bizarre motive
A 12-hour firefighting battle
Hundreds of millions in damage
A 17-year sentence
A final decision to scrap the vessel
The story feels almost fictional. It sounds like an exaggerated cautionary tale. But the facts are real.
It spreads because it captures a universal fear: that one irresponsible person in the wrong place can cause unimaginable damage.
It also sparks debate. Some people focus on Fury’s motive. Others focus on mental health. Others focus on shipyard safety, military budgets, or the fragility of complex systems. Some are simply stunned that a bag of burning rags could end the career of a nuclear submarine.
That shock keeps the story alive.
The Bigger Lesson
The biggest lesson of the USS Miami fire is not only that arson is dangerous. Everyone knows that.
The deeper lesson is that advanced systems are vulnerable to simple failures.
A submarine may contain billions of dollars in knowledge, engineering, training, and defense planning. But it can still be damaged by a small flame in the wrong compartment. A shipyard may have rules and procedures, but it can still be disrupted by one person’s reckless decision. A military fleet may be powerful, but it still depends on ordinary human responsibility.
Technology does not remove human risk.
It magnifies the consequences of human failure.
That is why safety culture matters so much. The more advanced the system, the more important discipline becomes. Every worker, every supervisor, every procedure, every inspection, and every emergency plan becomes part of the protection system.
The USS Miami was not lost because the Navy did not understand submarines.
It was lost because a human decision broke the safety chain.
Final Thoughts
The 2012 USS Miami fire remains one of the most shocking and costly arson cases in U.S. Navy history.
A civilian shipyard worker wanted to leave work early. He set fire to rags inside a nuclear-powered submarine. The fire spread quickly, burned for about 12 hours, injured responders, and caused catastrophic damage. Initial repair estimates were already hundreds of millions of dollars. Later assessments pushed the cost toward $700 million. The Navy eventually decided not to repair the submarine and instead decommissioned it.
Casey James Fury pleaded guilty and was sentenced to more than 17 years in federal prison.
The story is disturbing because the motive was so small and the consequences were so enormous. It shows how one reckless decision can endanger lives, destroy public property, damage national defense readiness, and leave a permanent scar on history.
The USS Miami was built for war.
It survived the ocean, deployments, and decades of service.
But it did not survive a fire started by a worker who wanted to go home.
That is what makes this incident so unforgettable.
It is not just a story about a submarine.
It is a warning about responsibility.
