KITTERY, Maine — Officials vented smoke and noxious fumes from a nuclear-powered submarine at a Maine shipyard Thursday so they could get inside to assess damage from a fire that took hours to put out.
Firefighters from the shipyard and coastal departments in Maine and New Hampshire spent Wednesday night and early Thursday fighting the fire on the USS Miami. Seven firefighters and crew members were hurt, but not badly. The cause of the fire is not yet known.
Rear Adm. Richard Breckenridge, commander of Submarine Group Two, said firefighters isolated the flames so they would not spread to nuclear propulsion spaces. There was nuclear fuel on board the sub, but the reactor has been shut down for two months and was unaffected.
The fire broke out Wednesday evening while the sub was in dry dock during a 20-month overhaul at Portsmouth Naval Shipyard. Authorities said nuclear components were not threatened, but firefighters had to work in cramped quarters and extreme heat.
Breckenridge praised the submarine’s crew, shipyard firefighters and additional firefighters from Maine and New Hampshire, saying there were “a lot of heroes that worked together to save the ship.”
“The fire spread to spaces within the submarine that were difficult to access, presenting a challenging situation for initial responders. But they persevered in incredible heat and smoke conditions, demonstrating exceptional courage,” the admiral told reporters at the entrance of the shipyard.
In a statement released Thursday, U.S. Sen. Susan Collins, R-Maine, said that “in situations like this, we see just how brave our first responders are.”
“I spoke to Capt. Fuller who described the tremendous effort it took to battle this blaze,” Collins continued. “I am impressed with the incredible work of some 150 firefighters, led by the shipyard’s unit, and involving firefighters from more than 15 communities in Maine, New Hampshire and Massachusetts. I understand this was an incredibly challenging and dangerous fire to fight because the heat and smoke were so intense and, at times, firefighters were operating in total darkness.”
Among those deployed to the scene were two trucks and about eight firefighters from the South Portland Fire Department, which brought tanks carrying about 1,000 gallons of foam to the site. Lt. Robb Couture said Thursday his department is unusually well trained for chemical and oil fires, because the city is home to a port, crude oil pipeline and two semiconductor manufacturers, among other things.
Couture said the South Portland firefighters remained on standby at the location and returned to the station after 3 a.m.
“Our resources were deployed, they were on hand if they needed to use them,” he said. “Our department has a certain expertise toward foam firefighting and hydrocarbon firefighting. … We also have members who have been to shipboard firefighting classes, so we not only have the personnel, but the resources to combat a fire like that.”
Working in the submarine’s favor was the fact that workers had removed some of the equipment and gutted part of the submarine during the retrofit, said U.S. Rep. Chellie Pingree after meeting with the shipyard commander.
Pingree described it as a “hot scary mess.”
“It takes a lot of guts to go into a burning building. But the idea of going into a submarine full of hot toxic smoke — that’s real courage,” she said.
Two sailors, three shipyard firefighters and two civilian firefighters were hurt, but their injuries were minor, officials said.
There were no details on the cause, and an investigation will take some time, said Breckenridge.
Crews responded at about 5:40 p.m. Wednesday to the USS Miami. It was not clear how many people were aboard at the time. The submarine is in the third month of a 20-month maintenance period.
Breckenridge said the fire started in the four forward compartments, which include living and command and control spaces.
No weapons were on board.
The USS Miami has a crew of 13 and 120 enlisted personnel. It arrived at the shipyard on March 1 to undergo maintenance work. It was commissioned in 1990 and its home port is Groton, Conn.
Residents reported hearing sirens from firetrucks and ambulances throughout the night, and the smoke spread over the area.
“It smelled like plastic burning,” said Janet Howe of Kittery, who lives three-quarters of a mile from the shipyard.
The fire damaged forward compartments including living quarters, the command and control center, and the torpedo room, leading to speculation on whether costly repairs would be undertaken on the 22-year-old Los Angeles-class attack submarine.
“The duration of the fire suggests extensive damage that could render the vessel useless. These submarines were designed decades ago. So they’re no longer state of the art,” said Loren Thompson, defense analyst at the Lexington Institute. “If this vessel returns to service, I will be amazed.”
Reporters were not allowed onto the base to see the submarine Thursday. But Pingree and others who viewed the vessel said there were no outward signs of damage because the fire was contained inside the 360-foot-long hull.

Lets thank our Union brothers and sisters for putting this danger to rest. They are there for us and we should be there for them. Thank you firefighters.
If it’s a slow news day, this could easily be the leading national news…. Here’s hoping the media will recognize the efforts of the firefighters and all involved. This could have easily been much worse.
Thank god that fire didn’t even touch that nuclear reactor. That would have been disasterous had that fire caused a containment breach. The fire crews did well in containing that fire.
Do you realize the magnitude and scope of fire that would be required to cause a “containment breach”?
Yup.
Its a little known fact that the reactor on subs are only protected by a few discarded pizza boxes and some tissue paper.
MisterX will disagree, because thats not what they said in “Hunt for Red October. “
OK – and can you tell me how the reactor is prepared prior to the sub being serviced?
No. I don’t think you do.
The fire would have done nothing to the reactor, since it was shut down. Most nuclear accidents result from the COOLING systems failing and the core overheating and melting-down. The reactor had been shut down (safely) 2 months prior…so absolutely nothing would have happened due to the fire. Nothing. The reactor WAS NOT REACTING.
The people in Japan were told that everything was OK.
I always wonder.
I am rolling my eyes so hard that they hurt.
I’d join you, but these hot pokers are in the way….
me too…
You should go hide underground until this all blows over. It will be safe there.
You would think with all the money that we spend on these ships that they would be protected by the best fire suppression systems available. So…….?
They are. The threat is ever-present on any vessel, though.
If she were at sea, the fire would have been quickly put out. Under overhaul in a shipyard, hatches may have been removed or blocked from closing, making it impossible to seal the affected compartment.
If the boat had been undergoing a refueling (a $200 million job, by the way) there may not have even been a core in the reactor.
My guess it’s a total loss after an intense, 12-hour fire.
thanks for the info…
I doubt that it’s a total loss. Do a search on the USS Hartford (SSN-768) and see the damage that was done to that in a collision with a surface ship. It had just undergone an overhaul, but they rebuilt it. Granted, it was a newer hull, but the same flight as the 755.
one would think,wouldn’t one???
More than likely the fire suppression system was disabled while work was in progress. This is done to prevent accidently release into compartments and endangering workers. It depends on the system used I would say but many workers have died in shipyards due to the accidental release of CO2 systems.
Many folks believe that God made people…there are hospitals…..everything can break ..regardless of the manufacturer.
The USS Miami was constructed in the late 1980s. A Navy report revealed that submarines of this generation had PCBs entrenched in cables, paint, and other substances. The Navy might have abated this source of toxin material; however, I doubt it and I also doubt that warnings were issued on response actions. The Navy will most likely keep the true story under wraps. The story should have pointed out the the nuclear reactors were still loaded with nuclear material event though nuclear warheads might have been removed. A close call which was reported and should be investigated in greater detail.
last time I checked we didn’t put nuclear weapons on 688 submarines any more.
Story says: “There was nuclear fuel on board the sub, but the reactor has been shut down for two months and was unaffected”.
Did you read the story before commenting?
The PNSY Fire Department is highly trained to deal with fires on submarines during overhaul. They are well aware of the poisonous environment inside a burning submarine.
/facepalm
It took shipyard firefighters plus crews from surrounding towns 12 hours to put this fire out! Good thing it didn’t happen at sea. Hopefully it was a fire that could only have been started as a result of dry dock operations….
They always say there was no release of radioactive material……..what else are they going to say……”run for your lives”?
Considering any and all radioactive material is kept in the engineroom and the bulkhead between the forward compartment and engineroom is roughly 12″ thick or a tank filled will seawater, I really doubt there was any chance of material release at all.
What do you prefer? Would you like them to not mention it at all and let people guess (panic)?
And if there WAS a release, there wouldn’t be much point in telling people to run away since they’d already be exposed, and likely dying.
