Plymouth bomb: How will disposal of WWII explosive work – and is there a risk it could explode?
More than 3,000 people have left their homes after an unexploded Second World War bomb was found in the back garden of a home in Plymouth.
Devon and Cornwall Police declared a major incident on Tuesday and evacuated properties within 200 metres of the bomb, extending it to 309 metres on Thursday.
Plymouth Council has confirmed bomb disposal experts from the army and navy plan to dispose of the bomb today – but how will they do it?
Here’s everything we know about the bomb and what’s being done to remove it – plus expertise from a bomb disposal expert.
What do we know about the bomb?
The bomb, which can also be referred to as an unexploded ordnance (UO), is a 500kg (1,102lb) German bomb from the Second World War, a Ministry of Defence (MoD) spokesperson has said.
The MoD identified it as a SC500 transverse fuzed airdrop weapon which, according to the Luftwaffe Resource Centre’s website, was a “general demolition bomb”.

It’s the same type of bomb that was found off the north coast of Guernsey in July 2023 by a local diver. The Royal Navy carried out a controlled explosion on the Guernsey bomb within an hour of specialist divers going to see it for the first time.
Andy Abbott, who spent 25 years in the Army Reserve’s bomb unit, told Sky News it was one of the biggest types of bombs the Germans dropped during the war that still get found today.
Where is the bomb and how was it found?
Officers were first called to a property on St Michael Avenue in Keyham on Tuesday, after a man reported finding the device while digging out the foundations for an extension in the garden.
Speaking to Plymouth Live, the man who called police said he actually found it “about a week ago”.

He said he “hit something with a spade, but we weren’t sure what it was at first”.
He said rain over the next few days made the object increasingly visible.
The man called the police on Tuesday and sent them photos.
“Five minutes later there’s a knock on the door and police officers asking to have a look,” he said. “The next minute they’re suggesting a cordon.”
Mr Abbott said bombs such as this one are usually found in big fields or in docks rather than more confined places such as the Keyham garden.
Who is dealing with it? And could it explode?
It was Devon and Cornwall Police who first came to the scene, but since then there has been the Royal Navy’s bomb disposal unit, military personnel and service members of various search and rescue teams, including from the local fire brigade.
Plymouth Council said the bomb would be removed and transported by military convoy through the city for disposal at sea.
In a statement, the council said the bomb disposal experts considered a controlled detonation on site, but ultimately decided “the safest and least impactful option is to remove the device from St Michael Avenue and travel to the Torpoint Ferry slipway – for the bomb to be disposed of at sea (beyond the Breakwater)”.
“Highly trained bomb disposal experts will carefully remove the device from the property and it will be transported by road in a military convoy, west along Parkside and Royal Navy Avenue, joining at the junction on Saltash Road to continue south joining Albert Road, turning right along Park Avenue and heading down Ferry Road to the Torpoint Ferry terminal,” the statement said.
Mr Abbott says “the best option is to always blow it up in situ”, but added the squad would have weighed up the damage that could be done to nearby houses and infrastructure.
When it comes to moving it “there is a risk, but it’s a minimal risk,” he added. “They wouldn’t be going with this process if they hadn’t weighed up the odds and found that it was pretty safe. But it is a big one, and there’s obviously always a slight risk.”
Explaining the process, he said: “They’ll probably lift the bomb onto the back of a truck, most likely with a crane.
“You protect it as much as you can on the back of the truck, probably by burying it in loads of sandbags, then they’ll gradually move it with a police cordon in place down to the sea.”
Images on Thursday showed tonnes of sand being delivered to the area, which a police source told Plymouth Live would be used to build a sand wall around the unexploded bomb.
Mr Abbott said sand and water bags are often used to mitigate for the bomb going off and that the bomb squad would have weighed up detonating the bomb on site, using them to contain the explosion.
“But you’re probably going to be blowing up four or five houses at least,” he said. “Even if you try and mitigate the explosion, the damage to those properties… they would be knocked down.”
Royal Naval Bomb Disposal experts dug around the explosive and used a special device to assess it.
A team of 200 volunteers from some of the organisations mentioned above have been visiting houses in the Keyham area, checking that the necessary homes have been evacuated and offering information to local residents.
Why not just diffuse it?
Mr Abbott says that while a fuse as old as the ones in a WW2 bomb are unlikely to be dangerous, there is a type of explosive acid often built into them which may cause problems while trying to diffuse it.
“Obviously the device is very old now. The fusion system they used on these were two fuses that transverse in the bomb itself,” he explained.
“So you’d have to mitigate the fusing. And by now, after this time, the fuses would be quite safe. The only issue you might have is sometimes these things were filled with picric acid, so you’d have picric crystals that can form after leaking and that is dangerous.
“So if you try and remove the fuse or take the fuse out that way, that could have the same effect as the fuse actually working. So you need to mitigate the risk of that too.”
How many people have been evacuated and when can they go back?
The cordon has meant 1,219 properties have been affected and an estimated 3,250 people have had to leave the area this week, with residents encouraged to stay with friends and family.
Those who have been evacuated have only been allowed to return to their homes to collect “urgent, essential items only” including medication or a pet, the council added.
But now residents of the Devon city living within 300 metres of the convoy route will need to completely evacuate their home between the hours of 2pm and 5pm this afternoon.
The council said it would “aim to keep residents informed throughout the operation” and that it would announce when roads are being reopened on its website and on social media.
Plymouth’s Life Centre has been set up as an emergency rest centre with tea and coffee, blankets, towels and toothbrushes, a creche and faith room available.
A similar incident to this one occurred in Plymouth in 2011, when an explosive device was unearthed by a workman at a building in Notte Street, near the city’s Hoe.
The device was made safe before it was moved to the seabed off Plymouth Sound, with an exclusion zone around it.
Plymouth saw more than 50 bombing attacks during the Second World War.
Singer Linda Nolan, who rose to fame alongside her sisters in The Nolans, has died after several years of battling cancer.
The Irish star, 65, and her sisters Coleen, Maureen, Bernie, Denise and Anne, had a run of hits in the late 1970s and ’80s – including the disco classic I’m In The Mood For Dancing.
Paying tribute on The Nolans‘ X account, her sisters described her as “a pop icon and beacon of hope”, who “faced incurable cancer with courage, grace and determination, inspiring millions”.
Linda died peacefully in hospital this morning, “embraced with love and comfort” with her siblings by her side, her agent Dermot McNamara said in a statement.
“As a member of The Nolans, one of the most successful girl groups of all time, Linda achieved global success; becoming the first Irish act to sell over a million records worldwide, touring the world and selling over 30 million records,” he said.
“Her distinctive voice and magnetic stage presence brought joy to fans around the world, securing her place as an icon of British and Irish entertainment.”
As well as her TV and musical career, Linda helped to raise more than £20 million for numerous charities, including Breast Cancer Now, Irish Cancer Society, Samaritans and others.
“Her selflessness and tireless commitment to making a difference in the lives of others will forever be a cornerstone of her legacy,” Mr McNamara said.

Linda’s death came after she was admitted to hospital with pneumonia over the weekend. She began receiving end-of-life care after slipping into a coma on Tuesday.
Details of a celebration of the star’s “remarkable life” will be shared in due course.
Linda was born to Tommy and Maureen Nolan in Dublin on 23 February 1959, the sixth of eight children.
Her parents were both singers and keen to turn their young family into a musical troupe. Linda made her stage debut aged just four.
Those early years put the siblings on track for a career in show business which lasted for decades. As well as I’m In The Mood For Dancing, The Nolans had hits with Gotta Pull Myself Together, Attention To Me and Don’t Make Waves, and they also had their own TV specials.
At their height, they toured with Frank Sinatra and were reported to have outsold The Beatles in Japan.
Linda left the group in 1983, but later reformed with her sisters for several comeback performances. She also became known for musical theatre, most notably performing the role of Mrs Johnstone in Blood Brothers for three years from 2000.

Four siblings struck by cancer
Linda was first diagnosed with breast cancer in 2005, and underwent a mastectomy two days before her 47th birthday.
After being given the all-clear in 2011, in 2017 she was diagnosed with secondary breast cancer. Three years later, Linda and Anne together revealed they were being treated for cancer once again.
The sisters were diagnosed with different forms of the disease just days apart after they returned home from filming a series of their show, The Nolans Go Cruising. Linda had cancer of the liver, while Anne had breast cancer.

They went on to write Stronger Together, an account of their journey that included frank details of their treatments and the side effects.
But in 2023, Linda revealed the cancer had spread to her brain and she was beginning treatment as part of a new drug trial.
The Nolans lost their second-youngest sister, Bernie, to cancer in 2013, aged 52.
Loose Women star Coleen Nolan also revealed she was diagnosed with skin cancer last year, and said she was using a chemotherapy cream to remove it.
Linda’s husband of 26 years, Brian Hudson, died in 2007 after being diagnosed with skin cancer.
Anne Nolan is now cancer-free.
Tributes to star ‘who was always a joy’
TV star and singer Cheryl Baker and comedian Tommy Cannon are among those who have paid tribute.
“I’m heartbroken to hear about the passing of Linda Nolan,” Cannon wrote on X. “I had the pleasure of working with her on so many occasions, and she was always a joy – full of warmth and love. My thoughts and love are with the Nolan girls and the whole family.”
“The most incredible voice, the wickedest sense of humour, such a massive talent,” Baker wrote. “You’re with Brian now, Lin.”
Loose Women also sent its love to her family. Linda appeared as a guest panellist on the ITV chat show over the years, alongside her sister Coleen.
The Blackpool Grand Theatre described her as “a true Blackpool icon”.
A 20-year-old trainee gas engineer who won £7.5m says he was back working on blocked drains the day after claiming his cash.
James Clarkson, 20, from Carlisle, Cumbria, found out he’d hit the £7,533,329 National Lottery jackpot on 4 January – but said he has no plans to quit his job.
“I was out in the cold fixing blocked drains the day after I found out I had won,” he said.
“It was a bit grim but that’s reality.
“I’m not going to stop working, I’m too young,” he added, admitting he knew it might sound “mad” to some.
“I want to qualify as a heating engineer and then go from there.
“I need to have a purpose in life, plus dad wouldn’t let me not work anyway. He says there are plenty of millionaires out there that still work and you need a reason to get up each day.”

Mr Clarkson added he still planned to have “some nice holidays” in between working, and revealed one of his first purchases was an all-inclusive luxury break to Cape Verde, along with a few designer items including a Gucci bag for his girlfriend and two new jackets for himself.
He said he also planned to splash out on a new car, possibly an Audi – but for now, he’s got his work van.
“If you drive a cold work van all day, going from job to job, you’d understand,” he said.
“The comfort, the steering, the heated seats. I realise how jammy that sounds, not many people my age can afford the car insurance let alone a car like that to drive.”

As a huge Manchester City fan, he said he was also looking to buy a season ticket at the Etihad Stadium, as well as taking care of his extended family – starting with paying off his parents’ mortgage.

He said: “I’ve been thinking about it a lot, it’s what I want to do. I told them last night and they seemed really overwhelmed.
“We are close and they have always been there for me. This win isn’t just for me, I want to make sure we all benefit.”
Mr Clarkson played on the National Lottery app, choosing his winning numbers – 16, 19, 22, 24, 27 and 35 – at random.
