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.
This scathing report goes a long way to answer the UK COVID-19 Inquiry’s critics, who have consistently attacked it as a costly waste of time.
They tried to undermine inquiry chair Lady Hallet’s attempt to understand what went wrong and how we might do better, and portray it as a lame exercise that would achieve very little.
Well, we now know that Boris Johnson’s “toxic and chaotic” government could well have prevented at least 23,000 deaths had they acted sooner and with greater urgency.
The response was “too little, too late”. And nobody in power truly understood the scale of the emerging threat or the urgency of the response it required.
The grieving families who lost loved ones in the pandemic want answers. They want names. And they want accountability.
The publication of the report into Module 2 of the inquiry will bring them no comfort, it may even cause them more distress.
But it will bring them closer to understanding why the UK’s response to this unprecedented health crisis was so poor.

We can easily identify the “advisers and ministers whose alleged rule breaking caused huge distress and undermined public confidence”.
And we know who was in charge of the Department of Health and Social Care as it misled the public by giving the impression that the UK was well prepared for the pandemic when it clearly was not.
All four UK governments failed to appreciate the scale of the threat posed by COVID-19 or the urgency of the response the pandemic required, a damning report published on Thursday has claimed.
Baroness Heather Hallett, the chair of the inquiry, described the response to the pandemic as “too little, too late”.
Tens of thousands of lives could have been saved during the first wave of COVID-19 had a mandatory lockdown been introduced a week earlier, the inquiry also found.
Noting how a “lack of urgency” made a mandatory lockdown “inevitable”, the report references modelling data to claim there could have been 23,000 fewer deaths during the first wave in England had it been introduced a week earlier.
The UK government first introduced advisory restrictions on 16 March 2020, including self-isolation, household quarantine and social distancing.
Had these measures been introduced sooner, the report states, the mandatory lockdown which followed from 23 March might not have been necessary at all.

All four UK govts ‘failed to appreciate’ scale of pandemic
COVID-19 first emerged in the Chinese city of Wuhan at the end of 2019, and as it developed into a worldwide pandemic, the UK went in and out of unprecedented lockdown measures for two years starting from March 2020.

Lady Hallett admitted in her summary that politicians in the government and devolved administrations were forced to make decisions where “there was often no right answer or good outcome”.
“Nonetheless,” she said, “I can summarise my findings of the response as ‘too little, too late'”.
Report goes long way to answer inquiry’s critics
This scathing report goes a long way to answer the Covid 19 Inquiry’s critics who have consistently attacked it as a costly waste of time.
They tried to undermine Lady Hallet’s attempt to understand what went wrong and how we might do better as a lame exercise that would achieve very little.

The response was “too little, too late”. And that nobody in power truly understood the scale of the emerging threat or the urgency of the response it required.
The grieving families who lost loved ones in the pandemic want answers. They want names. And they want accountability.
But that is beyond the remit of this Inquiry.
The publication of the report into Module 2 will bring them no comfort, it may even cause them more distress but it will bring them closer to understanding why the UK’s response to this unprecedented health crisis was so poor.
And we can easily identify the “advisors and ministers whose alleged rule breaking caused huge distress and undermined public confidence”.
Or who was in charge of the Department of Health and Social Care, as it misled the public by giving the impression that the UK was well prepared for the pandemic when it clearly was not.
‘Toxic culture’ at the heart of UK government
The report said there was “a toxic and chaotic culture” at the heart of the UK government during the pandemic.
The inquiry heard evidence about the “destabilising behaviour of a number of individuals” – including former No 10 adviser Dominic Cummings.
It said that by failing to tackle this chaotic culture – “and, at times, actively encouraging it” – former PM Boris Johnson “reinforced a culture in which the loudest voices prevailed and the views of other colleagues, particularly women, often went ignored, to the detriment of good decision-making”.
‘Misleading assurances’
The inquiry found all four governments in England, Scotland, Wales and Northern Ireland failed to understand the urgency of response the pandemic demanded in the early part of 2020.
The report reads: “This was compounded, in part, by misleading assurances from the Department of Health and Social Care and the widely held view that the UK was well prepared for a pandemic.”
The report notes how the UK government took a “high risk” when it significantly eased restrictions in England in July 2020 – “despite scientific advisers’ concerns about the public health risks of doing so”.
Lady Hallett has made 19 key recommendations which, if followed, she believes will better protect the UK in any future pandemic and improve decision-making in a crisis.
Repeated failings ‘inexcusable’
In a statement following the publication of Thursday’s report, Lady Hallett said there was a “serious failure” by all four governments to appreciate the level of “risk and calamity” facing the UK.
She said: “The tempo of the response should have been increased. It was not. February 2020 was a lost month.”
Lady Hallett said the inquiry does not advocate for national lockdowns, which she said should have been avoided if at all possible.
She said: “But to avoid them, governments must take timely and decisive action to control a spreading virus. The four governments of the UK did not.”
Lady Hallett said none of the governments were adequately prepared for the challenges and risks that a lockdown presented, and that many of the same failings were repeated later in 2020, which she said was “inexcusable”.
She added: “Each government had ample warning that the prevalence of the virus was increasing and would continue to do so into the winter months. Yet again, there was a failure to take timely and effective action.”
Fresh yellow weather warnings for ice have been issued for many areas of the UK, as some areas are threatened with blizzard conditions on Thursday.
An amber warning for snow – covering northeast England, including Scarborough, Whitby and parts south of Middlesbrough – is in force until 9pm on Thursday.
The Met Office said there could be “significant snow accumulations” over the North York Moors and parts of the Yorkshire Wolds with up to 25cm (10ins) on hills above 100m (330ft).
“Gusty winds, giving occasional blizzard conditions, and perhaps a few lightning strikes, may accompany some of the showers, posing as additional hazards,” the warning added.
Some A-roads in North Yorkshire were reported to be “gridlocked”, according to Shingi Mararike, Sky News’ North of England correspondent, but he added gritters are out to deal with the bad weather.

A number of yellow warnings are also in force for snow and/or ice across large parts of Britain.
In many of the warnings issued by the Met Office, there are concerns that where “showers persist and/or snow partially thaws and then refreezes overnight, this will bring a risk of ice”.

Jo Wheeler, Sky’s weather presenter, said clear skies will allow temperatures to tumble again as Thursday night approaches, “with an early and severe frost expected, and the associated risk of icy stretches on untreated roads and pavements”.
Coldest night so far
Overnight Wednesday into Thursday was the coldest of the season so far, according to the Met Office.
Temperatures dropped as low as -6.6C (20F) in Benson, Oxfordshire. There were two -6.4C (20F) temperatures recorded in Wales (in Sennybrigde) and in Scotland (Dundreggan).
While in Northern Ireland it fell to -2.8C (27F) in Altnahinch Filters.

As well as the one amber weather warning covering parts of the UK, there are two amber health alerts in place in three areas of England from the UK’s Health Security Agency.
An amber health alert is designed to prepare health services, including for the potential for a rise in deaths among the over-65s and people with health conditions.
The alerts are in effect in North East and North West England, along with the Yorkshire and the Humber region until 8am on 22 November.
Yellow cold-health alerts are in place for the rest of England and also expire at the same point.
Walk like a penguin
NHS Greater Glasgow and Clyde (NHSGGC) is recommending that people should walk like penguins to avoid dangerous slips and trips on icy surfaces.
The technique, which went viral in previous winters, is back for 2025 as part of the health board’s winter campaign.

Laura Halcrow, falls prevention lead at NHSGGC, said: “It might look funny, but waddling really works. A slip on ice can cause painful injuries and even hospital stays, especially for older people.”
Turning wet and windy
Sky’s weather presenter, Jo Wheeler, adds that the forecast is set to change this weekend.
“We’ll trade the cold sunshine and wintry showers for wet and windy conditions with rain turning heavy as it crosses the country on Saturday.”
“The British weather, fickle as always, looks like delivering a brief change to this milder westerly flow followed by an equally quick change back to a chilly northerly flow.”
