CHILLING satellite pictures reveal Iran’s sprawling secret nuclear site codenamed “Rainbow”.

Sources in the country have exposed how the facility is being used to develop nuclear-capable missiles with a 2,000-mile range, capable of striking US bases in the Middle East.

Tehran’s authoritarian regime is disguising nuclear bases as oil and chemical facilities, according to explosive documents shared with The Sun by the National Council of Resistance of Iran (NCRI).

Haunting aerial images expose a network of clandestine sites – including “Rainbow” – used by iron-fist leaders to create terrifying nuclear weapons.

It comes after senior political sources in Israel told The Sun how Iran’s nuclear scheme should have been dealt with “a long time ago”.

Sources in Tel Aviv disclosed that Israel is ready to strike Iran within weeks in a coordinated effort with the US if Tehran fails to negotiate a nuclear deal.

But despite US vice president JD Vance insisting talks are on the “right pathway”, Iran has secretly been majorly expanding its nuke empire.

A powerful nuclear blast from Iran could have disastrous consequences for the Middle East – and beyond – thanks to the capability of the warheads.

Now sources inside Iran have revealed the regime’s nuclear weaponisation entity, Organization of Defensive Innovation and Research’s (SPND) secret project to accelerate nuclear ability.

Hidden under the guise of a chemical production facility, the crowning jewel of the operation is a base known internally as the “Rangin Kaman (Rainbow) Site”.

It is some distance from Iran’s already known nuke bases, and is masked as a chemical production company known as Diba Energy Siba.

Dedicated to constructing various nuclear weapon components, the site sprawls across almost 2,500 acres in the Ivanaki region, southeast of Tehran.

Development of the base began in 2009, and it became operational around 2013, insiders from the People’s Mojahedin Organization of Iran(PMOI/MEK) said.

It was named Rainbow as it sits near a mountain range of the same name to its north.

According to SPND’s disturbing plan, the site is being used to boost development of nuclear warheads that can be mounted on ballistic missiles with a range of 2,000 miles (3,000km).

Barbaric leaders are pursuing the extraction and utilisation of tritium in the weapon’s construction.

The Rainbow site’s main focus is the extraction of tritium – a radioactive isotope used to enhance nuclear weapons, according to NCRI sources.

Incorporation of tritium increases the nuclear weapons’ yield -especially in implosion-type devices – and also enables the potential production of hydrogen bombs.

The hush-hush base is made up of three independent factory-like facilities, a headquarters, and a checkpoint at the entrance.

Security is high – with the entire road leading to the site under military control with local residents barred from entering.

With some sites already exposed, the regime established several other bases amid its twisted bid to ramp up the yield of nuclear weapons and the range of ballistic missiles.

The bases are: Garmsar Radar Site, Shahroud Missile Site and the expansion of Semnan Missile Site.

According to insiders, five front companies were created to shield the bases and conceal their true uses.

The parent company is named Pishtazan-e Towsee-ye San’ati-ye

Arya Razi (Pioneers of Arya Razi Industrial Development), chaired by IRGC Brigadier General Naser Maleki.

Former deputy of the Ministry of Defense’s Aerospace Organization Maleki was included in the UN’s sanctions list for being “involved in nuclear or ballistic missile activities” in 2007.

A spokesman for the NCRI told The Sun: “The regime’s goal has never been anything but building a nuclear bomb.

“Over the past three decades all of the regime’s nuclear activities have been first exposed, much of it by the NCRI and its network inside Iran and then the regime has been forced to acknowledge them.

“Obtaining nuclear weapons is part of the regime’s survival strategy and has absolutely no foundation in the production of civilian nuclear energy.

“While two trillion dollars have been spent on this programme over the past three decades, there has been no significant investment in the oil and gas industry.

“Today, a significant portion of the gasoline and natural gas consumed within Iran is imported from abroad.”

It comes after The Sun previously revealed three sites that Iran’s leaders claimed were being used as part of a space initiative.

An ex-military intelligence agent last month warned Israel will do “whatever it takes” to stop Iran’s nuclear strength.

Dr Raz Zimmt, whose work in the Israeli Defence Forces (IDF) focussed on Iran, said it would require a “long process” to properly downgrade Tehran’s nuclear capabilities – not just one attack.

Iran would no doubt retaliate by striking Israel, as it did last April with a huge barrage of missiles and drones after several officers were killed in an assault on its Damascus consulate in Syria.

An Iron Dome operator in Israel’s north told The Sun they do not fear a bombardment from Iran as they are “200 per cent prepared”.

“We have dealt with attacks from Iran before. We know how to deal with it again,” Technical Sergeant (Tsgt) Y said.

Early in April, top political and military sources in Jerusalem and Tel Aviv told The Sun that Israel’s top brass is preparing to blitz Iran.

They said its nuclear programme should have been “dealt with a long time ago”.

And Dr Zimmt, now a senior researcher at the Institute for National Security Studies, has warned the “next two or three months are crucial”.

Furious Donald Trump gave Ayatollah Ali Khamenei a two-month deadline to reach an agreement on Tehran’s nuclear scheme or face the consequences – bombing.

Dr Zimmt said it is likely Israel and the US will consider blitzing Iran within weeks.

He told The Sun: “We are at the closest point of reaching the possibility of either Israeli or an American attack against Iran.

“If there is no understanding or certainly agreement between the two sides by late June, July, I think that the prospects for military confrontation will be very high.

“What’s going to happen in the next few weeks and months, mostly between Iran and the US, will certainly have a major impact on the trajectory and decision whether we are going to face a military strike.”

The aim of any strikes on Iran would be to severely diminish the progress its regime has made in its nuclear capabilities.
