The IRGC Aerospace Force is working on the unconventional warheads for ballistic missiles as it transfers missile launchers to eastern regions of Iran, the sources said.
The sources, who requested anonymity due to the sensitivity of the matter, said these activities have accelerated in recent months and are being pursued amid rising regional tensions and Tehran’s concerns about the possibility of another direct confrontation with Israel and the United States.
Israeli Prime Minister Benjamin Netanyahu is in Florida to meet the US president on Monday, when he plans to brief Donald Trump on options for potential future strikes against Iran, amid concerns that Tehran is rebuilding ballistic missile production facilities and repairing air defenses damaged during a brief war in June.
Iran International’s sources say these programs are largely carried out under the supervision of the IRGC Aerospace Force and include optimizing ballistic missiles to carry chemical and biological agents, as well as upgrading the associated command-and-control systems.
The Revolutionary Guard, anticipating scenarios of large-scale conflict, is building capabilities that, in the view of the Islamic Republic’s decision-makers, would serve as a “complementary deterrent factor” alongside Iran’s conventional missile program, one source said.
The pursuit of chemical and biological warheads comes six months after Iran’s foreign minister described his country as “the largest victim of chemical weapons in modern history,” citing Saddam Hussein’s chemical attack on Sardasht in western Iran, which, according to OPCW documentation, killed more than 100 people in a large-scale mustard gas assault.
Asked about the contradiction, one source told Iran International, “The Iranian leadership views potential Israeli and American attacks as a threat to its very existence and intends, in the event of a conflict, to significantly raise the cost for the opposing side.”
There is a perception at the highest decision-making levels of the Islamic Republic that “the use of unconventional weapons can be justified in situations of existential threat," the source added.
Last week, Iran International reported that Western intelligence agencies had identified “unusual” activities by the IRGC Aerospace Force and had increased monitoring and surveillance of these movements.
Sources said intelligence services were tracking command-and-control signals as well as deployments and logistical movements linked to the force.
'Drastic change in Mideast deterrence balance'
Military analysts told Iran International that if these reports are confirmed, the development of chemical and biological warheads could drastically alter the region’s deterrence balance and trigger broad international reactions.
The deployment of such weapons would face widespread global condemnation and could pave the way for additional sanctions and intensified pressure on Tehran.
Tehran has consistently denied any effort to acquire unconventional weapons and has declared itself committed to its international obligations.
Over recent years, Iran has steadily increased the range, accuracy, and variety of its ballistic missiles, a program that has been one of the main sources of concern for Western countries and regional states.
