Iran is developing chemical and biological warheads for long-range ballistic missiles, military sources told Iran International, marking a significant potential shift in Tehran’s missile program amid rising regional tensions.
Iran’s Islamic Revolutionary Guard Corps (IRGC) Aerospace Force is working on unconventional warhead designs as it relocates missile launchers to the eastern part of the country, two unnamed sources said.
Background and Program Details
The initiative, described by sources as accelerating in recent months, involves adapting existing ballistic missile systems to carry non-conventional payloads, including chemical and biological agents.
Western intelligence agencies have reportedly detected what they describe as “unusual” movements and command-and-control signal activity tied to IRGC Aerospace Force deployments, prompting increased surveillance.
Officials familiar with the matter said Tehran frames the effort as a deterrent option under scenarios of direct conflict with Israel or the United States, even as Iranian authorities publicly deny any pursuit of weapons of mass destruction and reaffirm compliance with international commitments.
Regional Security Implications
If confirmed, the development of chemical and biological warheads could influence deterrence dynamics across the Middle East, raising questions about escalation risks and arms control regimes. Analysts say unconventional payloads on ballistic systems would draw global scrutiny and potential punitive measures.
Regional tensions remain high following a brief but intense conflict between Iran and Israel in June 2025, in which missile and air defense infrastructure sustained damage, according to multiple sources.
Strategic Context
Iran’s broader missile modernization has focused on increasing range and precision, a program that has long drawn concern from Western governments and regional states.
In parallel developments, Iran continues to advance its space capabilities, recently launching three domestically built satellites into orbit from Russia, a move that underscores dual-use technology concerns with strategic missile delivery systems.
