Iran's defense ministry successfully performed a sub-orbital launch of Zoljanah SLV. Zoljanah is a 3 stage SLV, with solid fuel engines at first and second stages and liquid engine for the third stage. this SLV can compete with world's current carriers and will become Iran's platform for launching light satellites with up to 220kg cargo into 500km circular orbit. Zoljana was built to reduce the costs and increase the launch speed, and as it can be launched from mobile launchers, this gives Iran the ability to reach Sun-synchronous orbit.

Zoljanah's first stage engine with 1.5m diameter can produce 75 tonne of thrust and can be upgraded to 100 tonne as well. first stage will reach 15km altitude in 70 seconds. second and third stages have 1.5m and 1.25 diameter as well.




Sarir SLV for launching 1 ton cargo into 1000km orbit and Sorush Slv for launching 15 tonne into 200km orbit (or equivalent cargo in GEO) are among the future projects.

This is massive .. arent SLV iCBMs with tweaking of trajectory..

There is a little more to it, but you are mostly correct. This current Zoljanah if used as an ICBM could have a range of 10,000km. However, if Iran decides to show an actual military standard ICBM, it could do so easily. It is just a matter of political will. The technology has been there for years.

At early stages these programs may seem similar, but eventually comparing an ICBM with SLV is like comparing a race car with a truck.
 
Iran’s New Space Rocket Could Double As A Nuclear Missile


Iran has a big new rocket. And it could complicate efforts by the Biden administration to slow or reverse Iran’s work on nuclear weapons.

The Iranian regime on Monday announced it had test-launched, for the first time, its Zuljanah space launch vehicle.

“The test helped Iran to achieve its most powerful rocket engine,” Ahmad Hosseini, a spokesperson for the defense ministry in Tehran, told state media.

Zuljanah is an 84-foot, three-stage rocket with a solid-fuel engine in its first and second stages and a liquid-fuel engine in its third stage. The rocket can loft a 500-pound payload as high as 310 miles, according to the Iranian government.

That’s adequate to place a satellite in low-Earth orbit and, for Iran, a big step forward for both its space program and its effort to develop delivery vehicles for possible future nuclear warheads.

A sold-fuel engine is more flexible and, because it requires less support equipment, easier to conceal than a liquid-fuel rocket is. But it requirements precise chemistry, engineering and manufacturing. “Making large solid-propellant motors is hard,” tweeted Jeffrey Lewis, an arms-control expert at the Middlebury Institute of International Studies in California.

Rocket in hand, Tehran now can advance both its space program and its nuclear-weapons program. Bear in mind that the very first space-launch vehicle was a version of the very first large, front-line ballistic missile—Nazi Germany’s V-2.

If you bent the Zuljanah’s trajectory, aiming for distance rather than height, you could carry a one-ton warhead as far as 3,100 miles, Lewis estimated. A weaponized Zuljanah could strike targets as far away as China and the United Kingdom.

The development adds tension to the already-fraught relations between the United States and Iran.

The administration of former President Barack Obama in 2015 negotiated an agreement—the Joint Comprehensive Plan of Action—that capped Iran’s nuclear-weapons development in exchange for relief from economic sanctions.

Then in 2018, Obama’s successor Donald Trump withdrew the United States from the deal. Trump’s move was part of a broader assault on Obama’s diplomatic legacy and also reflected a deeply-ingrained opposition within Trump’s Republican Party to any international relations based on compromise.

As the JCPAO unraveled, Iran resumed work on the basic components of a nuclear warhead. Tehran’s rockets have advanced in parallel. If Iran ever finishes its nuke, it already will have a missile capable of delivering it across much of the world.

It’s up to the Biden administration to put the genie back in the bottle. But that’s easier said than done.

President Joe Biden already has signaled the United States will rejoin the JCPOA. “We would like to make sure that we reestablish some of the parameters and constraints around the program that have fallen away over the course of the past two years,” said Jake Sullivan, Biden’s national security advisor.

But the 2015 agreement only covers warheads, not missiles. To constrain Iran’s rocketry, Biden will need to cut an entirely new deal.

A regional approach involving Iran’s closest neighbors is wisest, said Kelsey Davenport, a nuclear expert with the Arms Control Association in Washington, D.C. “Once the [2015] deal is restored, Biden should pursue a longer-term nuclear framework and support a security dialogue that is led by states in the region.”

“I think it makes more sense to pursue missile limitations within that latter set of issues because Iran's missiles are a regional threat,” Davenport added. “There are a number of restrictions that could be explored, including limits on range, fuel type, or number of launchers.”
 
This is great step in the development of ICBM's and also shows Iran's quantum leap in space technology and dual use rockets.
 
liquid fuels aren't always ICBMs but soiled fuels are military missiles with civilian name om them.
There are solid fuel slvs. They are usuall used for replacing satellites that needs to be replaced ASAP.
 
What is Iran's mega-missile and what does it mean for nuclear deal?


Tal Inbar: Recent launch was Iran signaling its missile program is off the table for Iran deal discussions

Iran launched a new satellite-carrying rocket recently, according to reports on February 3.Forbes has reported that it could carry a nuclear warhead, while other media have pointed out that the launch was done as the new Biden administration is discussing the Iran deal.

The importance of the launch looks to be multilayered, both signaling to the US the power of Iran’s missile program, and also potentially threatening Israel.

Tal Inbar was the head of the UAV research center at the Fisher Institute for Air and Space Strategic Studies until 2019, and he is an independent analyst on missiles, UAV and space. He frequently covers new Iranian missile technology.

“This is an important development,” he told The Jerusalem Post in an interview. Iran introduced a totally new launch vehicle, according to Inbar. “We knew about it from Iranian sources more than a year ago, and it was fired and launched without a satellite as a test flight, and it is a three-stage launch vehicle.”It is called Zoljanah.



What is interesting is that the first and second stages of the missile use solid fuel. They are 1.5 m. in diameter, and this is the largest solid rocket in Iran’s arsenal. The rocket, or SLV (Satellite Launch Vehicle), is a new revelation, says Inbar.

It comes amid all the press coverage of Iranian threats, including to Israel, and the discussion surrounding Washington rejoining the Iran deal. Indications point to Washington hesitating before bending to Iran’s demands. Israel has warned Iran about its continued quest for nuclear weapons. Iran has warned Israel not to attack.

“It is not only a genuine test flight of a satellite vehicle, but a signal to the US, Europe and Israel that missile technology is off the table,” said Inbar.

The big question is whether it has potential as a satellite launch vehicle. What does it mean in long-range ballistic missiles? Inbar wondered. It is not an ICBM (intercontinental ballistic missile), he points out, but it could deliver high explosives several thousand kilometers. Using solid propellant is also important because it means the time needed to roll it out and prepare it for launch is minimal.

There are questions about what kind of transporter erector launcher (TEL) it might be moved on. Iran has in the past showcased TELs of varying sizes.

Iran has an extensive rocket program and numerous long-range and precision missiles which include the Shahab 3, Sejjil, the Ghadr, Fateh 110 and Qiam.Iran also showed for the first time some official renderings of future launch vehicles which will be much bigger and heavier.

Additionally, the Islamic Republic has a plan to produce a satellite launch vehicle of 2.5 tons, says Inbar.

Iran launched a military satellite last year and may try to put another satellite into geosynchronous orbit in the future.“We will have to wait and see future trends, because Iran has become more advanced in the field of solid propulsion, for example, steerable and movable nozzles and composite material.

”Inbar also pointed out that the US didn’t mention the recent test, contrasting it with how the US often critiques major missile tests in North Korea. North Korea is rumored to work with Iran on rocket technology and has recently revealed its own mega-missiles.

Another issue of importance is to pay attention to who is running the tests in Iran. In the past the IRGC played a key role, but the Space Agency was involved in the recent test. Last year a major missile test included a missile with both solid and liquid fuel. Several weeks ago Iran also had its Great Prophet military drill where it launched a number of missiles.

Why does liquid or solid fuel matter?
Inbar noted that many Russian and North Korean large missiles are liquid-fueled. Rockets aimed for space have liquid fuel. Liquid fuel has become more efficient in recent years. Countries like Ukraine and China also have expertise in these types of rocket engines.

Today, “you see a transition of medium range in North Korea from liquid to solid because of operational advantages; you can launch them with no preparation and do salvos, so the trend is moving in both directions, depending on the purpose of the missile,” Inbar explained.

China’s new generation of missiles, for instance, are solid propulsion.

It remains to be seen what comes next with Iran’s missile program.
