Iran developing chemical, biological warheads for ballistic missiles: report

• The IRGC is reportedly developing biological and chemical warheads for its long-range missiles, viewing unconventional weapons as a necessary deterrent following the June 2025 military strikes by the US and ‘Israel’ on Iranian facilities.
• The program coincides with a strategic relocation of missile launchers to eastern Iran, a development expected to be a primary focus of Prime Minister Netanyahu’s briefing to President Trump during their Mar-a-Lago summit on Monday.

Iran's Islamic Revolutionary Guard Corps (IRGC) is pursuing the development of biological and chemical warheads for its long-range ballistic missiles, according to a report by Iranian opposition news outlet Iran International.

This development is reportedly led by the IRGC Aerospace Force.

The program involves adapting missiles to deliver chemical and biological agents, alongside upgrades to command-and-control systems.

The report said that the IRGC has accelerated these efforts in recent months, viewing unconventional weapons as a critical deterrent in scenarios of existential threat.

One source cited by the report said that Iranian leadership perceives potential attacks from ‘Israel’ and the United States as threats to the current leadership’s survival.

This development follows a brief conflict in June 2025, during which ‘Israel’ and the US targeted Iranian military and nuclear facilities, prompting Tehran to rebuild missile production and repair air defenses.

Concurrently, the IRGC is transferring missile launchers to eastern regions of Iran, a move that aligns with the broader reconfiguration of its ballistic missile infrastructure.

While specific missile types for these warheads were not detailed, Iran's arsenal includes advanced systems like the Zolfaghar, known for improved range and accuracy.

These transfers and developments occur against a backdrop of heightened monitoring by Western intelligence agencies, which have noted unusual IRGC activities in recent weeks.

Iran has historically positioned itself as a victim of chemical warfare, referencing the 1987 attack on Sardasht by Iraqi forces using mustard gas, as confirmed by the Organization for the Prohibition of Chemical Weapons (OPCW).

Tehran consistently denies pursuing weapons of mass destruction (WMD), having signed treaties such as the Biological and Toxin Weapons Convention (BTWC) and the Chemical Weapons Convention (CWC).

‘Israeli’ Prime Minister Benjamin Netanyahu's planned meeting with US President Donald Trump on Monday, is expected to address the topic of Iran.

US media said Netanyahu is expected to brief Trump on possible strike options to take against the Islamic Republic.
