What to know about bunker-buster bombs and Iran’s Fordo nuclear facility

  • Fordo is Iran’s second nuclear enrichment facility after Natanz

BANGKOK: If the US decides to support Israel more directly in its attack on Iran, one option for Washington would be to provide the “bunker-buster” bombs believed necessary to significantly damage the Fordo nuclear fuel enrichment plant, built deeply into a mountain.
Such a bomb would have to be dropped from an American aircraft, which could have wide-ranging ramifications, including jeopardizing any chance of Iran engaging in Trump’s desired talks on its nuclear program. Israeli officials have also suggested that there are other options for it to attack Fordo as it seeks to destroy Iran’s nuclear capabilities.
But aside from a commando attack on the ground or a nuclear strike, the bunker buster bomb seems the most likely option.
What is the bunker-buster bomb?
“Bunker buster” is a broad term used to describe bombs that are designed to penetrate deep below the surface before exploding. In this case, it refers to the latest GBU-57 A/B Massive Ordnance Penetrator bomb in the American arsenal. The roughly 30,000 pound (13,600 kilogram) precision-guided bomb is designed to attack deeply buried and hardened bunkers and tunnels, according to the US Air Force.
It’s believed to be able to penetrate about 200 feet (61 meters) below the surface before exploding, and the bombs can be dropped one after another, effectively drilling deeper and deeper with each successive blast.
The bomb carries a conventional warhead, but the International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility. However, Israeli strikes at another Iranian nuclear site, Natanz, on a centrifuge site have caused contamination only at the site itself, not the surrounding area, the IAEA has said.
How tough a target is Fordo?

Fordo is Iran’s second nuclear enrichment facility after Natanz, its main facility. So far, Israeli strikes aren’t known to have damaged Natanz’s underground enrichment hall, nor have the Israelis targeted tunnels the Iranians are digging nearby.
Fordo is smaller than Natanz, and is built into the side of a mountain near the city of Qom, about 60 miles (95 kilometers) southwest of Tehran. Construction is believed to have started around 2006 and it became first operational in 2009 — the same year Tehran publicly acknowledged its existence.
In addition to being an estimated 80 meters (260 feet) under rock and soil, the site is reportedly protected by Iranian and Russian surface-to-air missile systems. Those air defenses, however, likely have already been struck in the Israeli campaign.
Still, Israeli Prime Minister Benjamin Netanyahu has said the goal of attacking Iran was to eliminate its missile and nuclear program, which he described as an existential threat to Israel, and officials have said Fordo was part of that plan.
“This entire operation ... really has to be completed with the elimination of Fordo,” Yechiel Leiter, Israel’s ambassador to the US, told Fox News on Friday.
Why does the US need to be involved?
In theory, the GBU-57 A/B could be dropped by any bomber capable of carrying the weight, but at the moment the US has only configured and programed its B-2 Spirit stealth bomber to deliver the bomb, according to the Air Force.
The B-2 is only flown by the Air Force, and is produced by Northrop Grumman.
According to the manufacturer, the B-2 can carry a payload of 40,000 pounds (18,000 kilograms) but the US Air Force has said it has successfully tested the B-2 loaded with two GBU-57 A/B bunker busters — a total weight of some 60,000 pounds (27,200 kilograms).
The strategic long-range heavy bomber has a range of about 7,000 miles (11,000 kilometers) without refueling and 11,500 miles (18,500 kilometers) with one refueling, and can reach any point in the world within hours, according to Northrop Grumman.
Whether the US would get involved is another matter.
At the G7 meeting in Canada, Trump was asked what it would take for Washington to become involved militarily and he said: “I don’t want to talk about that.”
In a weekend interview with ABC News, Israeli Ambassador Leiter was asked about the possibility of the US helping attack Fordo and he emphasized Israel has only asked the US for defensive help.
“We have a number of contingencies ... which will enable us to deal with Fordo,” he said.
“Not everything is a matter of, you know, taking to the skies and bombing from afar.”


Iraq’s dreams of wheat independence dashed by water crisis

Iraq’s dreams of wheat independence dashed by water crisis 

  • Iraq ranks fifth globally for climate risk
  • Average temperatures in Iraq have risen nearly half a degree Celsius per decade since 2000

NAJAF: Iraqi wheat farmer Ma’an Al-Fatlawi has long depended on the nearby Euphrates River to feed his fields near the city of Najaf. But this year, those waters, which made the Fertile Crescent a cradle of ancient civilization 10,000 years ago, are drying up, and he sees few options.
“Drilling wells is not successful in our land, because the water is saline,” Al-Fatlawi said, as he stood by an irrigation canal near his parched fields awaiting the release of his allotted water supply.
A push by Iraq — historically among the Middle East’s biggest wheat importers — to guarantee food security by ensuring wheat production covers the country’s needs has led to three successive annual surpluses of the staple grain.
But those hard-won advances are now under threat as the driest year in modern history and record-low water levels in the Tigris and Euphrates rivers have reduced planting and could slash the harvest by up to 50 percent this season.
“Iraq is facing one of the most severe droughts that has been observed in decades,” the UN Food and Agriculture Organization’s Iraq representative Salah El Hajj Hassan told Reuters.

VULNERABLE TO NATURE AND NEIGHBOURS
The crisis is laying bare Iraq’s vulnerability.
A largely desert nation, Iraq ranks fifth globally for climate risk, according to the UN’s Global Environment Outlook. Average temperatures in Iraq have risen nearly half a degree Celsius per decade since 2000 and could climb by up to 5.6 C by the end of the century compared to the period before industrialization, according to the International Energy Agency. Rainfall is projected to decline.
But Iraq is also at the mercy of its neighbors for 70 percent of its water supply. And Turkiye and Iran have been using upstream dams to take a greater share of the region’s shared resource.
The FAO says the diminishing amount of water that has trickled down to Iraq is the biggest factor behind the current crisis, which has forced Baghdad to introduce rationing.
Iraq’s water reserves have plunged from 60 billion cubic meters in 2020 to less than 4 billion today, said El Hajj Hassan, who expects wheat production this season to drop by 30 percent to 50 percent.
“Rain-fed and irrigated agriculture are directly affected nationwide,” he said.

EFFORTS TO END IMPORT DEPENDENCE UNDER THREAT
To wean the country off its dependence on imports, Iraq’s government has in recent years paid for high-yield seeds and inputs, promoted modern irrigation and desert farming to expand cultivation, and subsidised grain purchases to offer farmers more than double global wheat prices.
It is a plan that, though expensive, has boosted strategic wheat reserves to over 6 million metric tons in some seasons, overwhelming Iraq’s silo capacity. The government, which purchased around 5.1 million tons of the 2025 harvest, said in September that those reserves could meet up to a year of demand.
Others, however, including Harry Istepanian — a water expert and founder of Iraq Climate Change Center — now expect imports to rise again, putting the country at greater risk of higher food prices with knock-on effects for trade and government budgets.
“Iraq’s water and food security crisis is no longer just an environmental problem; it has immediate economic and security spillovers,” Istepanian told Reuters.
A preliminary FAO forecast anticipates wheat import needs for the 2025/26 marketing year to increase to about 2.4 million tons.
Global wheat markets are currently oversupplied, offering cheaper options, but Iraq could once again face price volatility.
Iraq’s trade ministry did not respond to a request for comment on the likelihood of increased imports.
In response to the crisis, the ministry of agriculture capped river-irrigated wheat at 1 million dunams in the 2025/26 season — half last season’s level — and mandated modern irrigation techniques including drip and sprinkler systems to replace flood irrigation through open canals, which loses water through evaporation and seepage.
A dunam is a measurement of area roughly equivalent to a quarter acre.
The ministry is allocating 3.5 million dunams in desert areas using groundwater. That too is contingent on the use of modern irrigation.
“The plan was implemented in two phases,” said Mahdi Dhamad Al-Qaisi, an adviser to the agriculture minister. “Both require modern irrigation.”
Rice cultivation, meanwhile, which is far more water-intensive than wheat, was banned nationwide.

RURAL LIVELIHOODS AT RISK
One ton of wheat production in Iraq requires about 1,100 cubic meters of water, said Ammar Abdul-Khaliq, head of the Wells and Groundwater Authority in southern Iraq. Pivoting to more dependence on wells to replace river water is risky.
“If water extraction continues without scientific study, groundwater reserves will decline,” he said.
Basra aquifers, he said, have already fallen by three to five meters.
Groundwater irrigation systems are also expensive due to the required infrastructure like sprinklers and concrete basins. That presents a further economic challenge to rural Iraqis, who make up around 30 percent of the population.
Some 170,000 people have already been displaced in rural areas due to water scarcity, the FAO’s El Hajj Hassan said.
“This is not a matter of only food security,” he said. “It’s worse when we look at it from the perspective of livelihoods.”
At his farm in Najaf, Al-Fatlawi is now experiencing that first-hand, having cut his wheat acreage to a fifth of its normal level this season and laid off all but two of his 10 workers.
“We rely on river water,” he said.
