WANA (Oct 27) – Iran’s new ballistic missile, Qasem Basir, is a capability that the Iranian government says signals a significant advance in Iran’s missile forces and could reshape calculations on future battlefields. Officials describe the weapon as a solid-fuel, precision-guided ballistic system with features designed to defeat modern air- and missile-defense networks.

 

Solid fuel, long range, sub-meter accuracy

The Ministry of Defense’s Aerospace Industries Organization unveiled Qasem Basir on May 04. According to the announcement, the missile uses solid propellant and is an optimized version of the earlier Haj Qasem design. The developers say the missile has a range of more than 1,200 kilometres, a circular error probable (CEP) of less than 1 metre, and carries a 500-kg warhead.

 

 

Advanced terminal guidance: thermal imaging seeker

Officials emphasize that Qasem Basir is equipped with an advanced thermal-imaging (optical) seeker for terminal guidance. The seeker, which relies on infrared sensors, is described as capable of identifying and discriminating a primary target among decoys and secondary objects, and of functioning effectively in low-light, cloudy, or dusty conditions. Because the thermal sensor is passive, it does not emit signals and is therefore presented as inherently resistant to radio detection and some forms of electronic interference.

 

Navigation without GPS, improved maneuverability

The missile’s navigation suite reportedly avoids GPS altogether, relying instead on inertial and combined optical-inertial navigation methods. Iranian engineers say this design increases resilience to jamming and spoofing and allows the system to operate reliably even when satellite navigation is denied. Developers also claim the missile has enhanced maneuverability and a multi-phase flight profile intended to improve its ability to penetrate modern defensive systems.

 

 

Designed to resist electronic warfare and defeat modern defenses

Iranian statements assert that Qasem Basir has demonstrated strong performance under heavy electronic-warfare conditions and that recent tests — including a trial conducted on April 17 — proved the missile’s robustness. The makers claim the system is capable of defeating a range of advanced missile-defense systems, naming Arrow, THAAD, Iron Dome, and David’s Sling among those it can overcome.

 

What Tehran says the system means

Iran frames Qasem Basir as the product of years of specialized research and domestic engineering, combining indigenous know-how in propulsion, navigation, and terminal guidance. Officials portray the missile as a “new card” in Iran’s deterrence toolkit — a capability that, while not completely disclosed in public detail, is intended to alter strategic calculations by improving precision, survivability, and independence from satellite navigation.
