Tehran, Iran – Mehrdad Akhlaghi Ketabchi has been appointed Iran’s defence minister at a time when the war with the United States is expected to escalate.

The 68-year-old was approved on Sunday by parliament, which has convened online since the start of the US-Israel war on Iran on February 28, to assume leadership of the Ministry of Defence and Armed Forces Logistics. In total, 237 lawmakers voted in favour of Akhlaghi’s appointment and 15 against.

Former Defence Minister Aziz Nasirzadeh was killed along with a large number of other senior figures, including Supreme Leader Ali Khamenei, on the opening day of the war.

The position was filled temporarily by Majid Ebn-e Reza, who will now become Akhlaghi’s deputy.

Akhlaghi will be responsible for rebuilding and expanding Iran’s military-industrial infrastructure, which has been heavily targeted by the US and Israel.

The new minister’s defence plans were approved earlier by senior military authorities, President Masoud Pezeshkian and parliament’s Commission on National Security and Foreign Policy.

“The Islamic Republic of Iran will not be the instigator of aggression against any country but will defend the territorial integrity of the country strongly and to the death against any aggression,” Pezeshkian said.

The president said Akhlaghi has more than 42 years of experience in the Defence Ministry and related organisations.

His principal expertise is in ballistic missiles, solid-fuel propulsion, aerospace technology and military-industrial production, according to state media.

Previously, he served as the head of the Shahid Bagheri Industrial Group, the Aerospace Industries Organization and the Defence Industries Organization. Akhlaghi and these entities are all subject to sanctions by the US. He is also under United Nations sanctions.

He has been associated with developing several missile types and related weapons-development projects over the past decades, according to Tasnim, a newspaper linked with the Islamic Revolutionary Guard Corps (IRGC),

Akhlaghi reportedly played a role in expanding the major Sejjil and Zolfaghar family of Iranian ballistic missiles as well as precision-guided weapons, such as the Almas missiles and Yasin guided bombs.

He is also said to have expertise in space launchers, research rockets and infrastructure associated with the Imam Khomeini Space Center in Semnan. These have all been critical elements in Iran’s wars against Israel and the US.

This month, Iran’s Defence Ministry spokesman, Brigadier General Reza Talaei-Nik, told reporters that Akhlaghi’s nomination reflected Iran’s need to increase the quantity and quality of strategic weapons, particularly missiles and drones.

“Offensive arms are being actively improved,” the spokesman said.

The US has repeatedly claimed that it has destroyed most of Iran’s military-industrial capacities, but Tehran has maintained it continues to have considerable offensive and defensive capabilities outside the reach of US and Israeli bombs. These weapons have been upgraded based on Iran’s new war experience, it has insisted.

Akhlaghi told members of parliament this month that he had met with senior military commanders, including the commander-in-chief of the IRGC, Brigadier General Ahmad Vahidi, to develop a better understanding of their requirements during and after the war.

His priorities as defence minister would be faster military-industrial development, air defences, incorporation of emerging technologies using government and private sector firms, improvements in armed-forces welfare and development of international military cooperation, according to reports.

In his first comments as defence minister on Sunday, Akhlaghi taunted the administration of US President Donald Trump, which this month threatened to use the “mother of all bombs” on Iran’s nuclear and energy infrastructure.

“We have made preparations and continue our work with ease of mind,” he told reporters. “The US president must think of getting his forces out of our region in one piece. If he drops one bomb, he must see how many of his troops he will have to evacuate horizontally.”
