Underground

IRGC says underground military complexes allow missile production to continue even under heavy bombardment.

Iran is building underground military complexes able to sustain weapons production and storage even under heavy bombardment, according to the country’s Islamic Revolutionary Guards Corps (IRGC).

IRGC spokesperson Hossein Mohebbi made a series of announcements on Saturday about the military’s capabilities during a news conference in Tehran, Iranian media reported.

Among the achievements listed were an “underground missile city” set to be unveiled, the semi-official Tasnim news agency reported.

Mohebbi said the IRGC had rapidly transferred its missile and drone production lines from the surface to underground facilities. This allows Iran to continue producing missiles while its adversaries assumed its stockpiles were dwindling, he explained.

The spokesperson also outlined advances in stealth technology. He maintained that such improvements had allowed Iran’s missiles and drones to pierce air defence systems and accurately strike targets during previous rounds of fighting with the United States and Israel.

“Today, every weapon used by the IRGC Aerospace Force is manufactured using homegrown knowledge and expertise. Moreover, our products are not even derived from reverse-engineering captured enemy war material,” Iran’s IRNA news agency quoted Mohebbi as saying.

A recent report by US newspaper, The Wall Street Journal, shows that Iran caused billions of dollars in damage to US bases throughout the Middle East during previous rounds of fighting.

Meanwhile, a separate report by the Reuters news agency found that Iran had successfully targeted Gulf infrastructure on at least 135 occasions during the same period, causing billions of dollars in damage and lost revenues.

Mohebbi also warned on Saturday that restrictions on the range of Iranian missiles had been lifted. The warning follows a statement from Supreme Leader Mojtaba Khamenei, who said that there would be “no geographical limits” to Iran’s response if it were attacked again by the US and Israel.

The US-Israeli war on Iran was launched on February 28, prompting Tehran to close the Strait of Hormuz and triggering a global energy crisis. Mediation efforts have stepped up recently, as regional countries hope to bring the war to an end.

On Friday, President Donald Trump said the US military launched limited strikes on Iran’s Qeshm Island, while also claiming Washington had made “a lot of progress” in talks with Iran.

Tehran has repeatedly warned that it will target Gulf energy infrastructure if the fighting resumes. Such attacks would likely push energy prices even higher.

Meanwhile, Washington has also imposed additional sanctions on Iran as it seeks to force Tehran to concede to its demands. The restrictions have further strained the country’s economy, forcing Iran to adopt new trade routes.

On Saturday, US Central Command (CENTCOM) announced it was establishing a new task force that will support ongoing US efforts to prevent Iran from using land routes to transport advanced weapons and other materials.

The US has also imposed a naval blockade on Iran to prevent it from exporting oil.

OUR Spotlight On column suggests what to do and see in the top holiday spots as well as lesser known regions in the UK and farther afield.

This week, in honour of Halloween, we’re taking a look at Nottingham – one of the spookiest destinations in the UK, regardless of the time of year you visit.

MUST SEE/DO

If you’re into your spooks, the National Justice Museum should be top of your list.

The former court and prison dates back to 1375 and it has seen some terrifying things in those years.

Criminals were brought to justice here and held in the dungeons ahead of public hangings and executions.

Paranormal sightings are frequently reported, with some ghost hunters recording cold spots in the basements and hearing distant screams.

COOL CRUISE

TAKING OFF

Car-free islands to beach cities – trending 2027 destinations including UK city

If that’s not thrilling enough, book onto the Original Nottingham Ghost Walk, one of the oldest of its kind in the UK.

The two-hour experience ticks off some creepy locations within the city’s historic Castle Quarter – it will have your hairs standing on end.

HIDDEN GEM

Did you know that Nottingham is home to an underground labyrinth of caves?

Locals first began constructing the City of caves over a thousand years ago, during the Anglo-Saxon Era.

Nottingham’s unique geology and soft rock meant that workers were able to easily carve out spaces and homes that were protected from harsh weather and the natural elements.

Generations continued to carve out more spaces to use as cellars and then as bomb shelters during WWII.

Having seen so much history, it’s no wonder people have reported hearing mysterious noises down there.

Family tickets cost from £62 for two adults and two children.

BEST VIEW

You’ll have to venture a little out of the city centre for the best views, but you certainly won’t regret a visit to Wollaton Hall & Deer Park.

Spread across 500 acres, this glorious green space looks particularly magnificent at this time of year, when the autumn leaves are shedding.

For some chills and thrills, pop into the main manor house, once the home of Lady Middleton.

She suffered a stroke after falling from her horse back in the 18th century, but rumour has it that her ghost still wanders the halls today, dressed in a white gown.

RATED RESTAURANT

The tacos at city-centre restaurant Taquero are scarily good.

Favourites include the pork brisket which comes topped with pickled red cabbage and apple salsa and the baja with fried fish, chipotle aioli and coriander.

The Mexican restaurant has just updated its menus for autumn, too.

BEST BAR

Ye Olde Trip to Jerusalem claims to be Britain’s oldest inn, having been pouring brews since 1189.

According to legend, the Knights Templar and crusaders ventured here to down ale before setting off for the holy land.

It’s much cosier today and with a much better drinks selection, too!

Think local ales, modern beers, wines and classic cocktails such as the Old Fashioned. Its rooms are small and pokey, which adds to its charm.

HOTEL PICK

If the aim of the game is to be spooked then you may want to check into the Bestwood Lodge Hotel, a 25-minute drive from the city centre.

Once a Victorian hunting lodge surrounded by 700 acres of parkland, the now-hotel is supposedly haunted by the spirit of Nell Gwynn (the mistress of King Charles II).

You may notice strange happenings like lights flickering on and off and the noise of footsteps.

In general, the hotel is atmospheric with roaring fireplaces and dark wooden features. Rooms cost from £75 per night.

JUNIOR Andre has revealed he was forced to get a job on the London Underground after blowing all the money he made from his music career at just 17.

The singer, now 21, made the surprising confession during tonight’s opening episode of Celebrity Race Across the World, admitting he had learned the hard way about managing his finances.

Junior, the son of Peter Andre and Katie Price, opened up about his past while working alongside younger sister Princess, 19, picking coconuts in exchange for free food and accommodation during the first leg of their race.

He said: “Growing up in the public eye, I’m used to people prejudging me and stereotyping how I’m going to be.”

The star continued: “People just assume that I’m just living off Mummy and Daddy’s money, but I’m not going to take money from my parents. That’s just not me.”

Revealing how he ended up taking on a demanding night job, Junior explained: “I released my first single at 17, and I got a big chunk of money come in for my music, and I blew it all, so I had to go get a job.”

He added: “I worked on the London Underground, on the Piccadilly line, 10pm to 6am, and that was intense. I was doing wiring. I was carrying heavy materials, basically doing just loads of manual labour stuff.”

Despite having no previous experience of the job, he insisted he had thrown himself into it. “I may not have known as many things as everyone else on the Underground, but I worked hard. I like to think that I did the best that I could, and it taught me a lot about money.”

Reflecting on what he learned, Junior added: “You know, it taught me about having a budget that you need for your weekly shop.”

Junior and Princess are among four celebrity pairs taking part in the fourth series of the BBC travel competition, which sees contestants race thousands of miles without the usual luxuries of modern travel.

This year’s line-up also features Eurovision star Sam Ryder and his friend and tour manager Kaz, singer Ella Eyre and childhood friend Nana Pepera, and former Soccer Saturday host Jeff Stelling alongside his son Matt.

The teams are racing from Kuching in Malaysian Borneo to Melbourne, Australia, navigating unfamiliar destinations and completing challenges while sticking to a limited budget.

Iran is rebuilding Eagle 44, a hardened underground airbase carved into the side of a mountain that can shelter fighter aircraft, drones, and potentially cruise and ballistic missiles, despite the remote facility absorbing at least three rounds of airstrikes this year. High-resolution satellite imagery captured by Planet Labs in late September and reviewed by TWZ shows a new section of taxiway completed, several support buildings still destroyed or damaged, wrecked equipment cleared off the pavement, and obstacles that were placed to obstruct the runway now removed. Construction is ongoing at a time when the Pentagon and Trump administration maintain there is little remaining of the Iranian air force for such a facility to protect.

Eagle 44, also called ‘Oghab 44’ after the 44th anniversary of the 1979 revolution, was unveiled by Iranian state media in February 2023 when senior officials visited what was described as the country’s newest underground airbase. Islamic Republic of Iran Air Force (IRIAF) F-4D/E Phantom IIs, armed with AGM-65 Maverick air-to-ground missiles, laser and electro-optically guided bombs, unguided ‘dumb’ bombs, as well as domestically produced anti-ship missiles, were shown using the facility in the footage. The IRIAF had roughly 60 examples in service at the time, its most numerous combat jet by some margin, though how many remain today, and are actually operational, is unknown. In addition to the Phantoms, one-way attack drones were also seen in the background.

The IRIAF, rather than the Islamic Revolutionary Guard Corps (IRGC) Aerospace Force, operates the base, which is located in Hormozgan province and sits in the foothills of the Zagros Mountains, approximately 100 miles northwest of the Strait of Hormuz. Iranian state media described it as “one of the army’s most important air force bases, with fighters equipped with long-range cruise missiles and built in the depths of the Earth.” Then-Chief of Staff of the Armed Forces Maj. Gen. Mohammad Bagheri, who was present at the unveiling, warned that “any attack on Iran from our enemies, including Israel, will see a response from our many air force bases including Eagle 44.” He was eliminated in the opening strikes of the Twelve-Day War, which Israel dubbed Operation Rising Lion, in June 2025.

Work on the cavernous underground tunnel complex began in 2013. Construction of a 2.7-mile main runway, situated on the northern side of the base on a valley floor below the mountain range, started roughly eight years later. Two taxiways run through a smaller ridge connecting the runway to four entrances to the primary tunnel complex, where the jets and weapons are stored, although only one taxiway is currently operational.

The promotional video released in 2023 revealed at least one internal blast door, as well as branches from the main tunnel to revetment areas to park fighters and drones. A support compound of several buildings is on the west side of the base, next to the unfinished taxiway. The purpose of each structure is unclear, but a functioning airbase requires maintenance and repair facilities, crew quarters, reserves of fuel and munitions, security and force protection assets, and infrastructure to coordinate air traffic control and command and control functions.

The United States kicked off Operation Epic Fury alongside Israel on February 28, launching a massive wave of strikes against Iran from the west and south. Eagle 44 is located within striking distance of the munitions carried by air wings embarked on U.S. Navy aircraft carriers operating in the northern Arabian Sea and missiles fired by the guided-missile destroyers that escort them, as well as Air Force tactical and strategic aircraft and Army assets in the region. However, low-resolution images reviewed by TWZ through March 16 indicated that while the base was targeted, little damage was visible.

As the U.S. and Israel continued the relentless air campaign over the next several weeks, the base was targeted again at the end of March, with greater effect, according to a report from The New York Times. High-resolution images the paper reviewed revealed impact craters on the taxiways near the tunnel entrances, one building leveled, and small mounds placed along the runway, presumably to prevent enemy aircraft from landing. Battle damage assessments suggested the strikes were intended to cut the underground caverns off from the runway, trapping whatever was inside and preventing takeoff. The report did not state whether U.S. or Israeli aircraft carried out the attack, and Israeli officials declined to comment. However, the U.S. was primarily responsible for pressuring Iran’s southern flank, while the Israelis attacked the western front.

After the fragile April ceasefire collapsed and the U.S. imposed a second blockade, U.S. Central Command (CENTCOM), based out of MacDill Air Force Base in Tampa, Florida, and responsible for executing day-to-day operations of the war, launched multiple strikes across Iran on July 15, and Eagle 44 was hit for at least a third time. An analysis published by Soar Atlas, a satellite imagery provider, identified four aimpoints on July 16, with cratered taxiways and damage to additional infrastructure. According to that analysis, the structures targeted were related to the base’s construction unit, but TWZ has not independently verified this claim. The Pentagon and CENTCOM have not specifically named Eagle 44 in any press briefing or release, and Iran has not acknowledged the base was struck.

The Planet Labs satellite imagery from September 29, obtained exclusively by TWZ, indicates that Iran began reconstruction after the July attacks and that the effort is ongoing.

The main runway, previously blocked by obstacles meant to deter and prevent unauthorized aircraft from landing, is now clear. On the western taxiway (marked in red below), a new section leading into the ridge ‘pass-through’ is complete, with its finished upper cement-concrete layer visible. On the other side of the pass, construction of the next segment is underway, with a subgrade layer of stabilized, compacted dirt laid down but not yet paved (orange). Farther south, in front of the western tunnel entrances, impact craters (blue) are still visible. When finished, the second taxiway will provide a direct link between the western hangars and the runway, allowing additional aircraft to move freely without sharing a single taxiway, a major bottleneck for higher operational tempos and more complex sortie launches and recoveries. A second functional taxiway and tunnel would also provide critical redundancy if the other is hit.

On the primary eastern taxiway, two dark streaks (green) that appeared following the strikes in July run off the edge of the pavement, likely debris left by equipment that was struck and removed. Notably, the streak marks match the width of the wreckage, suggesting it was bulldozed or pushed off the taxiway to reopen it. There is no sign of the equipment being recovered, only that it was cleared out of the way.

In the main support compound (yellow) next to the western taxiway, two buildings are clearly destroyed and a third is damaged. They have not been rebuilt yet, which is consistent with previous reporting from The Times and Soar Atlas that the attacks degraded construction capabilities, and suggests the regime may be focused on completing and repairing the taxiways rather than the installations.

The four entrances to the main tunnel complex (white), arranged in two pairs less than half a mile apart at the end of each taxiway on the southern part of the base, appear to be intact, although the angle makes it unclear whether they are open or sealed. What’s inside the mountain, and how many fighters remain in Iran’s inventory, is unknown. Regardless of the status of the fighter fleet, as we noted earlier, the base can also store drones and could be packed with cruise or ballistic missiles.

The U.S. and Israel have a range of bunker buster bombs that could be used in an attempt to collapse the tunnel entrances, a major choke point for any underground weapons storage site. While not destroying what is being held within, doing so would block anything inside from leaving — and being used — for a period of time. Additionally, the pass-through tunnels make for easy targets, and hitting them would keep fixed-wing aircraft from reaching the runway. No impact points on the mountain itself or damage to the portals inside is apparent, but they could have been sealed and hit farther in, which may not be highly visible via satellite imagery. Reaching the main storage caverns themselves would likely be far harder. Larger bunker busters in the U.S. inventory include the GBU-57 Massive Ordnance Penetrator (MOP) guided munition, which could be capable of reaching deeper into the main site, but these are very limited in number and can only be delivered by the Air Force’s B-2A Spirit stealth bombers. It’s highly unlikely the U.S. would expend such resources on a site like this over many others of higher strategic importance.

Eagle 44 is not the only base that Iran is fixing during the lull in hostilities. By the end of May, Iran had cleared 50 of 69 tunnel entrances struck at 18 underground facilities, including some “missile cities,” according to a report by CNN − and that number is likely higher now. Planet Labs, Airbus, and Vantor imagery reviewed by The Wall Street Journal in July showed rebuilt entrances near Kangavar, fresh excavation at Dezful, and repairs near Kermanshah. “They have very impressive industrialization and reconstruction capabilities,” Israeli Brig. Gen. Ran Kochav told the paper. “They refilled their stockpiles,” he added.

A Western official told Bloomberg earlier this month that Iran “remains well-stocked with ballistic missiles and some anti-ship missiles, and can quickly add more,” and a U.S. official posited in May that “the Iranians have exceeded all timelines the IC [Intelligence Community] had for reconstitution.” Both assessments are at odds with what the White House and Pentagon have repeatedly claimed. Secretary Pete Hegseth stated in April that Iran’s air force was “wiped out” and its missile program was “functionally destroyed; launchers, production facilities, and existing stockpiles depleted and decimated,” while acknowledging a week later that the regime was “digging out” launchers, missiles, and bombed facilities but had “no ability to replenish offensive or defensive capabilities.” In May, CENTCOM Commander Adm. Brad Cooper told Congress, “Before Operation Epic Fury, the Iranian Air Force flew between 30 and 100 sorties each day; today that number is zero.” More recently, at a campaign rally in Kansas on Monday, U.S. President Donald Trump said, “They have no air force… their 229 beautiful fighter jets are now scattered all over the runways, the beautiful runways of the Islamic Republic of Iran.”

At the very least, strikes on Eagle 44 cratered the taxiways and degraded support infrastructure, which likely put at least some of whatever airpower is stored there, if any, out of action. But even after enduring months of war and extreme economic pressure due to the ongoing U.S. blockade and sanctions, as well as dealing with damage across the country, Tehran continues to prioritize construction on the remote base. That fact alone could put it back on the target list if the U.S. and Israel launch another operation. But above all else, it points to how important this facility is to the regime, for whatever reason.
